Not just a new Sound Blaster:
A new 16-bit audio standard
Introducing the Sound Blaster 16
Digital Audio Platform. A new concept
in sound cards. And a new standard
for 16-bit PC audio.
You WON'T Believe Your Ears.
PC audio never sounded so good-
genuine CD-quality audio with fully
12% more dynaniic

Hmids-frce mm better signal-to-
vokewniwi ^^ noise ratio than
any con\petiiig 16-bit sound board. Plus
software data compression that delivers
16-bit fidelity while maximizing disk storage capacit)',
But there's more. Included in the Sound Blaster 16
package is the biggest advancement in PC control since
the invention of the mouse: our exclusive VoiceAssist'"
software. It's a sophisticated speech recognition interface
that uses a 32,000-con\mand library to control Windows
applications hands-free!
THE ONLY SOUND CARD THAT GROWS WITH YOU.

Here's a list
of tlie ten best
products [
saw at this year's
Spring COMDEX.
Spring COMDEX, held this
past May in Atlanta, Geor-
gia, will go down in the his-
tory books as the best
COMDEX to date. Exhibit
halls were jam-packed with ea-
ger attendees, and a record
number of exhibitors filled the
show floors and demonstrat-
ed an amazing assortment of
cool new products. Here are
the ten best products I saw at
this year's show.
10. Doublecase makes a se-
ries of superlight, hard cases
designed to fit almost any note-
book. The Doublecase name
comes from the case's de-
sign, which uses two hard
shells for each wall. The in-
side of the case is dense
foam rubber that you can
mold to tit almost any note-
book or laptop. Your traveling
PC is probably as safe in a
Doublecase as it is on your
desk back at the office. Pric-
es start at $59.95.
9. Star has really upped
the ante in color printers with
its sleek, new SJ-144. This su-
perb small printer uses a new
medium to print color pages
that are amazingly crisp and
rich. Cost per page is about
the same as with a color
DeskJet, and the suggested
retail price is $599.
8. if you find yourself switch-
ing screen resolutions in Win-
dows, you'll love Any View
from Binar. This clever soft-
ware add-in lets you click on
a button to go from 640 x
480 to 800 X 600 to 1024 x
768. You also get a virtual
desktop, and perhaps most im-
pressive of all, you can adjust
your screen's scaling so rul-
ers in programs like Word for
Windows and PageMaker
measure exactly one real-
world inch. Neat.
7. Image-editing and
screen capture programs are
a large, competitive category
in Windows, and a new ver-
sion of ImagePals (U-Lead) in-
troduced at COMDEX goes to
the head of the class. With ex-
cellent tools for editing
bitmaps, editing color, and
capturing screens, all in a
scrapbook interface, Image-
Pals is fast, powerful, and
easy to use.
6. Intel's Pentium proces-
sor has caused quite a stir in
the last few months, and at
this COMDEX we saw some
of the first machines that are
actually designed around the
chip. The Pentium's potential
is amazing, but hardware sys-
tems and software must be
specially designed to take
full advantage of this poten-
tial. When they are, perform-
ance increases of nearly ten
times over that possible with
a 486 are attainable. Putting a
Pentium in a 486 systenn will
double your performance.
5. Here's a tie. Corel and Mi-
crografx have long been the
two giants in the illustration
program category. Both com-
panies had new products at
COMDEX, and both looked
great. The programs seemed
amazingly easy to use, even
for nonprofessionals. Co-
relDRAW! 4.0 includes every-
thing but the kitchen sink in
its box, and the company's
selling the previous version of
CorelDRAW! for $199, which
is a super deal. Designer 4.0
won't have quite as much in
its package as CorelDRAW!,
but you'll still find lots of good-
ies including clip art, fonts,
and a bitmap editor
4. Last year, presentation
programs became a major cat-
egory. This year, multimedia
presentation software is really
hitting its stride, and the best
newcomer is Compel from
Asymetrix. It's easy to use,
and it has all the tools you'll
need to combine dazzling
graphics, animations, and
sounds.
3- If you're in the business
of creating Windows help
files, RoboHelp 2.0 from Blue
Sky Software is the most ad-
vanced tool available. New at
COMDEX, RoboHelp 2.0
works with Word for Windows
and, as the name implies, au-
tomates help file creation, An-
yone who's created help files
by hand will appreciate the
point-and-click ease with
which you can build topics
and jumps and include
bitmaps in your help files, You
can also compile and test
your help files, all from a tool-
box that RoboHelp installs in
Word.
2. Windows programmers
and power users now have a
high-powered tool to investi-
gate what's going on behind
the scenes in Windows. Win-
Scope from Periscope lets an-
yone spy on the Windows mes-
sages, API calls, and hooks,
Ever wonder what's really hap-
pening when you drag a file
from File Manager and drop it
on Notepad? With WinScope
you can find out.
1. Page layout has long
been the domain of ultraexpen-
sive, powerful programs like
QuarkXPress and Page-
Maker. Now, PagePlus from
Serif changes the formula
with a program that's ultrainex-
pensive and very powerful.
This amazing program will do
the lion's share of what the
heavyweights do and at a
price of $59.95. PagePlus
even surpasses Quark and
PageMaker in a couple of ar-
eas, and it's easier to use
than either D

GENERATION OPERATING SYSTEM
i^^
Microsoft's recently re-
leased Windows NT (New
TeclinolQgy) is a bold
attempt to extend Win-
dows' incredible marl<:et success far
beyond individual desktop PCs into
companywide networlo and essential
mission-critical applications. NT is an
industrial-strengtii operating system
capable of competing head to head
with OS/2 and UNIX, as well as a fully
featured network operating system for
both modest peer-to-peer networks (S
la Windows for Workgroups) and large
client/server networks (like those sup-
ported by Novell NetWare}. Yet, to the
average user, Windows NT looks and
feels almost identical to today's
Windows 3.1.
To understand what Windows NT
is, it's important first to understand
what it is not. NT is not the next ver-
sion of Windows 3.1 or Windows for
Workgroups, although it can do virtu-
ally everything that those two operat-
ing environments can do, and far
more. Unlike today's Windows 3.1,
which is an operating environment
that runs on top of DOS, NT is an
entirely new operating system, built
from the ground up to demolish the
limitations that PC users and software
developers have labored under for
more than a decade. This means that
NT can tackle sophisticated net-
worked applications that are far
beyond the reach of Windows 3.1; but
as we'll see, it exacts a price in the
form of hefty processor, memory, and
hard disk requirements.
NT's designers had to balance
their desire to develop a state-of-the-
art operating system, capable of satis-
fying the computing needs of large
organizations, with the knowledge that
NT had to be compatible with the
huge installed base of DOS and
Windows applications. The result is a
32-bit operating system that pays
homage to many of today's most pop-
ular computing buzzwords {multitask-
ing, multiprocessing, objects, and
client/server computing) while sup-
porting 16-bit DOS and Windows
applications.
Leaving DOS in the Dust
What are some of the practical
improvements of Windows NT over
today's DOS and Windows combina-
tion? For one, Windows NT says good-
bye to the memory management limi-
tations of DOS. No more questions
about vjhen and how to use extended
versus expanded memory, and no
more memory managers such as
HIMEM, EMM386, or QEMM-386 to
tweak and configure. Unlike DOS with
its arcane segmented memory archi-
8 COMPUTE AUGUST 1993
lecture, NT supports a linear memory
address space of four gigabytes (two
gigabytes for programs and two giga-
bytes for the operating system), which
is more than enough for all but main-
frame- and supercomputer-class
applications.
If you've tried to run multiple appli-
cations at once under Windows 3.1,
you know how limited Windows' capa-
bilities are. Trying to print a long docu-
ment or transfer a file by modem while
working in your word processor or
spreadsheet can be an agonizing
process. Even worse, if any of your
programs crash, it can bring the entire
system to a screeching halt. Windows
NT, however, eliminates these prob-
lems with a sophisticated preemptive
multitasking system that switches
between programs so quickly and
smoothly that, from the user's point of
view, each program appears to run
nearly at top speed. An even more
sophisticated capability called multi-
threading enables many programs, or
in NT terminology, processes, to be
broken down into two or more threads,
each of which can be executed con-
currently. Muitithreading enables NT
to do many more things at once, and
it's widely applied within NT itself in
order to speed things up. However,
programs must be written with multi-
threading in mind in order to get maxi-
mum performance.
in addition, NT's virtual memory
manager (which gives each program
more room to run by combining avail-
able RAM with hard disk space) pro-
tects the system by keeping programs
and system tasks from interfering with
each other. If one program crashes,
Windows NT itself and the remaining
programs continue to run. The frustrat-
ing General Protection Faults and
freezes that are common in Windows
3.1 are largely a thing of the past in
Windows NT.
For complex applications that
require more power than one proces-
sor can provide (such as sophisticat-
ed engineering-design problems or
transaction-processing systems for
high-speed processing of sales
orders or airline reservations), NT sup-
ports multiprocessing. With this capa-
bility, two or more processors can
work in concert to execute applica-
tions. In fact, by combining muitipro-
cessing and multithreading, each
processor can run different portions of
the same application, or entirely differ-
ent applications, in order to gain
potentially enormous performance
improvements. However, most appli-
cations must be written from the
ground up with multiprocessing in
mind; otherwise, performance
improvements are modest at best,
Virtually no existing Windows applica-
tions can take full advantage of multi-
processing without involving extensive
redesign.
The Compatibility Suite
Even though its internal architecture is
completely different from that of DOS,
Windows NT runs most existing DOS
and Windows applications without
modification. To do so, NT uses an
emulator. Macintosh and NeXT users
will be familiar with one such emulator
called SoftPC, which completely
reproduces the PC hardware architec-
ture in software, so that DOS and
Windows applications can run "inside"
SoftPC under Macintosh System 7 or
NextStep. Insignia Solutions, the com-
pany that developed SoftPC, worked
with Microsoft to develop a similar
emulator for Windows NT called the
Virtual DOS Machine, or VDM. The
VDM emulates both DOS and the
standard PC hardware, and it runs all
DOS applications except those that
bypass the operating system to talk
directly to hardware, such as some
games, CAD programs, and older
applications that require direct access
to hardware for acceptable graphics
or hard disk performance.
Windows applications also run on
NT by using an emulator; in this case,
an emulator called Windows on
Win32, or WOW for short, runs on top
of the VDM. WOW supports most stan-
dard and enhanced mode Windows
applications, but not Windows 3.0 real
mode applications. (As with DOS, any
application that bypasses Windows
and directly manipulates memory or
hardware is unlikely to work with
Windows NT.) Multiple applications
can run simultaneously inside WOW,
but since the WOW environment so
closely duplicates Windows, an appli-
cation crash within WOW has a good
chance of crashing other running
applications and possibly even WOW
itself, Unlike in DOS/Windows-based
systems, however, a crash within
WOW will not affect any other non-
Windows applications. In other words,
while existing DOS and Windows
applications are no more "bulletproof"
in Windows NT than they are today in
Windows 3.1, the overall system is far
more reliable.
In addition to DOS, Windows, and
Windows NT applications, NT also
runs a limited set of OS/2 and UNIX-
like applications. For example, NT can
run character mode OS/2 1.x applica-
tions. In reality, this feature is of very
limited usefulness, because most
OS/2 1.x applications have long since
been upgraded to take advantage of
CompuServe does Windows.
Introducing a whole new way to look
at CompuServe: CompuServ^e Information
Manager for Windows (WinCIM"). It's a fully
integrated Windows application, and lets you
take advantage of Windo^vs
when you're on CompuSer\'e.
It'll make your session
faster, more efficient,
easier, and a lot more fun.
With the help of icons
and pull-down menus, you'll
find your CompuServe time is almost effortless
Cruise the forums, browse through your
messages, download files — it's all about as
simple as clicking a mouse button.
And with WinCIM you can do more
offline, too. That means everything from
writing letters to reading the answers to your
hardware and software questions can be done
J much more economically.
So take a look for yourself.
If you're already a CompuServe

and capabilities than those specified
in POSIX 1.0.
Further. POSIX doesn't yet support
the X Window system or higher-level
graphical user interface tools that are
quickly becoming an integral part of
most UNIX systems. Therefore, as
with OS/2, Windows NT's POSIX sup-
port is, for now, primarily a token ges-
ture aimed at providing cross-platform
compatibility, rather than an immedi-
ately useful feature.
Keeping Secrets
As mentioned earlier, Windows NT
includes sophisticated networking
capabilities. Existing Windows tor
Workgroups (WFW) users will recog-
nize NT's networking features as
extensions of WFW's capabilities. NT
systems can share files, printers, and
other resources {such as networkable
modems) on a peer-to-peer basis with
other NT systems, as well as with
WFW systems. These peer-to-peer

networks don't require expensive ded-
icated file and print servers. Or you
can clioose to create client/server net-
work configurations, witin NT systems
acting as file, print, and application
servers to other NT, WFW, LAN
fvlanager, and DOS-based systems. In
fact. Windows NT includes approxi-
mately 90 percent of the functions and
features found in Microsoft's LAN
tvlanager 3.0. NT supports the network
protocols used by LAN Manager and
IBM's LAN Server, as well as the pro-
tocols used by most UNIX systems
and the worldwide Internet.
Additionally, Novell NetWare users
aren't left out; Windows NT systems
can be connected as clients to exist-
ing NetWare servers.
A powerful networked operating
system like Windows NT will usually
be used in applications in which more
than one user needs to use the net-
work; otherwise, there's little reason to
upgrade from Windows 3.1. As soon
as multiple users begin to access a
single system or network of systems,
security becomes essential. Each user
will have applications and data files
that must remain private to him or her,
while some programs and files will
need to be shared by other users.
More importantly, critical functions
such as modifying operating system
files and adding or deleting users
must be strictly limited to authorized
system administrators.
Windows NT includes the Security
Subsystem, which requires all users to
log on with a unique user name and
password in order to gain initial
access and then strictly controls
access to files and subdirectories
according to rules set up by the sys-
tem administrator. NT meets the U.S.
government's 02 level of security,
meaning that it can be used for mod-
erately sensitive applications
(although its safeguards are insuffi-
cient for secret or even more sensitive
data). By comparison, OS/2 has only
rudimentary security features: it relies
on LAN Server's network-based secu-
rity for more extensive protection.
UNIX, on the other hand, has had
password protection and access con-
trol features for years, but only recent-
ly have some desktop UNIX vendors
(Univei and SunSoft) brought their
products' security up to 02 standards.
These vendors require users to pur-
chase add-on software to achieve the
same level of security built into
Windows NT.
In order to keep track of who has
permission to access which files and
subdirectories, a file system (which
manages the directories and file
attributes for each hard disk) must
12 COMPUTE AUGUST 1993
maintain and update a great deal of
security information. The FAT file sys-
tem used by DOS and Windows
makes no allowances for security, nor
does it provide the fail-safe features
required in mission-critical applica-
tions, where a single disk failure could
have catastrophic results.
Windows NT's developers devised
a new file system, called NTFS (NT
File System) that works hand in hand
with the Security Subsystem to keep
track of security permissions for every
file, subdirectory, and user. In addi-
tion, for reliability, NTFS supports disk
mirroring, in which two disk drives
contain identical information, so that
the mirror drive can take over instantly
in the event of a failure in the primary
drive. NTFS can also improve disk
performance with a technique called
disk striping, in which files are written,
or "striped," across two or more physi-
cal disk drives.
Because each drive can read or
write a different block of data from the
same file simultaneously, the time it
takes to perform disk functions can be
dramatically reduced. In addition, by
adding parity, which stores disk data
with a small amount of redundant
information, small data errors can
often be corrected on the fly, and data
damaged by more severe hardware or
software failures can usually still be
reconstructed.
In addition to NTFS. Windows NT is
also compatible with the FAT file sys-
tem and OS/2's High Performance File
System (HPFS), although NT's secuhty
features can't be used with FAT or
HPFS volumes.
Intel and Beyond
One of the most important and excit-
ing new features of Windows NT is its
ability to run on non-Intel processors.
UNIX can run on a wide variety of dif-
ferent computers, from desktops to
supercomputers, but even today, DOS
and Windows can run oniy on either
Intel or Intel-compatible processors,
or on top of software that emulates the
Intel x86 architecture. In addition to
Intel's family of 386, 486, and Pentium
processors, NT supports the new gen-
eration of high-performance RISC
(Reduced Instruction Set Computer)
processors that offer big price and
performance advantages over CISC
(Complex Instruction Set Computer)
processors (such as Intel's x86 and
Motorola's 680x0 families). Windows
NT currently runs on MIPS 4000 RISC
processors from Silicon Graphics, as
well as on Digital Equipment's Alpha
RISC processor family. Future support
for Hewlett-Packard's HP-PA and
Intergraph's Clipper RISC processors
is planned, and IBM is rumored to be
working on moving NT to the PowerPC
processor family that will form the
backbone of Apple's and IBM's next
generation of desktop computers.
Later this year, the first RISC PCs
will begin to appear, using Alpha and
MIPS 4000 processors. These PCs will
be priced slightly higher than, and
look and run very much like, existing
high-end PCs; they'll have EISA-bus
slots and support ISA- and EISA-bus
expansion cards.
For superior video display and
hard disk performance, most will also
support local-bus architectures such
as VL-Bus or PCI. They'll use the
same keyboards, mice, monitors,
modems, phnters, and other peripher-
als as conventional PCs, but instead
of DOS and Windows, they'll run either
Windows NT or a flavor of UNIX.
These RISC PCs wilt run existing
DOS and Windows applications under
NT about as fast as a 33-MHz or
clock-doubled 50-MHz 486-based PC
does today under DOS, but they'll
equal or exceed all but the fastest
available Pentium chips when running
native Windows NT applications,
(Existing DOS and Windows applica-
tions won't have to be modified in
order to run on these systems, but
new NT applications will have to be
recompiled in order to run on different
processor designs.) Windows NT will
help to turn these RISC PCs into real
competitors for Intel-based PCs and
servers, and in so doing will help to
drive down the price of high-end 486-
and Pentium-based systems,
NT Versus OS/2 and UNIX
Windows NT is often compared to
OS/2 and UNIX. In fact, when NT was
first conceived by Microsoft, it wasn't
called Windows NT at all, Instead, it
was called OS/2 3.0, and it was
intended to be Microsoft's next-gener-
ation platform-independent version of
OS/2. The split between IBM and
iVIicrosoft sealed OS/2 3.0's fate, and
the announcement of the ill-fated
Advanced Computing Environment in
the fall of 1991 by MIPS, Compaq,
Microsoft, and others was the first for-
mal acknowledgment that OS/2 3.0
had metamorphosed into Windows
NT. Today, Windows NT 3.1 will com-
pete head to head with OS/2 2.1, as
well as with a variety of UNIX flavors,
including UnixWare (Novell/Univel),
SCO UNIX (Santa Cruz Operation),
Solaris (SunSoft), and NextStep
(NeXT).
The table provided on the preced-
ing page summarizes the similarities
and differences between NT. OS/2,
and genehc UNIX.

The Price of Power
Windows NT's power and flexibility
has its price. NT demands faster
processors, more nemory, and big-
ger hard disks. Unlike Windows 3.1,
which runs on virtually any 386, 486,
or Pentium processor, f^/licrosoft
states that at least a 25-MH2 386 is
required for NT. In fact, anything short
of a 486 is underpowered so far as
NT is concerned. A 25-MHz 486SX is
probably the minimum processor
needed for adequate performance.
Also, be prepared to buy more RAM.
Until March of this year. Microsoft's
stated goal was to make NT run in
8MB of RAM with acceptable speed,
but software developers who tested
the first two beta versions of NT were
dubious that Microsoft would ever
achieve its goal. With the March beta
release, Microsoft threw in the towel
and raised the minimum requirement
to "12MB of RAM, with the best perfor-
mance possible only on systems with
16MB or more.
Finally, NT needs lots of disk
space; the complete operating sys-
tem, including networking, OS/2, and
POSIX support, requires 80MB of stor-
age. The complete Software Develop-
ment Kit requires another 40MB. Swap
files for virtual memory will require
another 10-20MB, so depending on
whether you1l be developing applica-
tions or simply running them, you'll
need 100-140MB of hard disk space
just to get started. And don't plan to
save money or slots by using Stacker
or SpeedStor; at the present time, NT
is totally incompatible with these utili-
ties. In fact, NT doesn't even under-
stand Microsoft's own DoubleSpace
compression, which is built into DOS
6. (Microsoft is working on a new NT
disk driver that will be able to read
and write DoubleSpace volumes, but
it won't be available until sometime
after NT ships.)
Should You Switch?
It's clear ttiat Windows NT is a big step
beyond DOS and Windows, However,
for the average home or small-business
user, does it make sense to switch?
The answer depends on how success-
fully you can get your tasks done today
with Windows 3.1. If you're constantly
battling with DOS's memory limitations,
if you need the ability to do both peer-
to-peer and client/server computing, or
if you want to move a favorite UNIX
application to Windows, NT could be
right for you, Keep in mind, though,
that NT currently doesn't support multi-
user capabilities with low-cost charac-
ter-oriented terminals. Unless you're
going to develop your own application
from scratch, or move an existing
application from UNIX to NT, be sure
that your software suppliers are ready-
ing NT versions of their programs
before you take the plunge. Otherwise,
you'll be stuck with expensive NT sys-
tems that offer little practical benefit
over what you're already using.
On the other hand, if you're cur-
rently using Windows applications and
you don't really need the additional

power of Windows NT, or if you have
an existing small LANtastic, NetWare,
or Windov/s for Workgroups network
and you're not planning to add lots of
new users, today's DOS/Windows
combination is probably fine for you.
In fact, switching to NT might actually
be counterproductive for two reasons.
First, as I explained earlier, both DOS
and Windows applications run in erru-
lators under NT, not in the native NT
environment. Like all emulators. NT's
Virtual DOS Machine and Windows on
Win32 exact a performance penalty.
The second reason for not switch-
ing is the extra expense involved in
equipping each PC to run Windows
NT. Applications that run perfectly well
today on a 25-MH2 386SX will proba-
bly need at least a 25-MHz 486SX in
order to satisfy NT's requirements and
still provide adequate performance. In
addition, a system with 8f\/IB of RAf^
that's perfectly adequate for your cur-
rent DOS/Windows needs will require
at least 12MB and probably 16MB of
RAM for acceptable performance with
NT. For existing applications, you'l
get even greater performance gains
by upgrading your PC's processor
and memory while keeping your cur-
rent DOS/Windows software configu-
ration. Your existing software will run
significantly faster, and you'll be ready
for Windows NT in the future.
It you're willing to wait until some-
time in 1994 for a "lite" version of NT,
Microsoft is working on Windows 4.0,
often referred to by its code name,
Chicago. According to industry
sources, Chicago will have most of the
features of Windows NT except its
ability to act as a server on client/serv-
er networks and its support for OS/2
and POSIX applications. Like NT,
Chicago will be a complete operating
system and thus will no longer require
DOS in order to run. Chicago's memo-
ry and disk requirements will probabiy
be significantly more modest than
NT's. For exampie, Microsoft claims
that Chicago will be able to run on
PCs with 8MB of RAM; however, keep
in mind that up until March of this
year, Microsoft claimed that NT would
also be able to run in SMB. Also, indi-
cations are that like today's DOS and
Windows, Chicago will run only on
Intel and Intel-compatibie processors,
although that might change if NT is a
big hit on non-Intel platforms,
The bottom line is that Windows NT
offers true multitasking, multithreading,
and multiprocessing, along with exten-
sive networking capabilities, while
remaining compatible with most exist-
ing DOS and Windows applications. In
addition to Intel x86- and Pentium-
based PCs, you'll also be able to run
NT on RISC-based PCs and worksta-
tions using MIPS 4000 and Digital
Equipment's Alpha processors.
However, to use NT with your present
PC. be prepared to upgrade your sys-
tem with a faster processor, more
RAM, and a bigger hard disk. If you're
a home or small-business PC user,
there's little reason to switch to NT
unless you really need one or more of
its advanced features. Windows 4.0. or
Chicago, due out sometime next year,
promises to offer most of NT's func-
tionality in a smaller package. In short,
Windows NT is a powerhouse that's
likely to be overkill for all but the most
demanding applications, but it offers a
first look at the future of desktop com-
puting, Microsoft style.

Reviews by Tom Campbell
This is an exciting time in the
Windows database arena.
And it's no wonder: Database
applications are, depending
on whom you believe, the most
popular or the second-most-pop-
ular use for computers.
The arena wasn't always this
interesting- When Windows 1.0
came out in 1984, there was noth-
ing. A few vertical market appli-
cations appeared with 2.0, as
well as a couple of failed Mac
ports. Microsoft was curiously
silent all this time, developing, we
now know, Access. Microsoft was
also well behind the market
curve, for by version 3.1,
Windows had a downright respect-
able selection of database manag-
ers. Approach Software released
Approach 1.0 to great acclaim;
it's at version 2.0 now and shows
Windows at its best.
SPC's Superbase had a com-
manding lead of the market be-
fore Access sold nearly a nnillion
copies at the loss-leading price
of $100: with its intelligent imple-
mentation of a database-oriented
BASIC, Superbase is still a pre-
mier development environment.
Fox Software, now subsumed by
Microsoft, had done a great job
porting its FoxBase dBASE clone
to the Macintosh and was revers-
ing the process when Microsoft
■n,f/)T.'w'0""
16 COMPUTE AUGUST 1993
bought Fox for a cool $175 mil-
lion. The reversal was complete
this year when FoxPro appeared
on Windows, DOS, Mac, and
UNIX — a desktop computer
grand slam. Borland was hardly
idle. It was developing a dBASE
clone for Windows and reengineer-
ing Paradox, its flagship data-
base. After more than a year's
delay, Paradox emerged from the
chrysalis just in time to battle
with FileMaker Pro, from that
insanely great software company
called Apple,
As interesting as the market
soap opera is, the products are
much more so. These full-fea-
tured database managers can all
be used to create mousing, win-
dowing, push-button database
applications. With some of them
it stops there; you can add push
buttons, but not list boxes, com-
bo boxes, or radio buttons. All of
them import dBASE files — a
great relief from times past when
compatibility wasn't even men-
tioned by database publishers.
Some of them provide macro lan-
guages and ways to replace the
standard menus with your own;
some don't. All have some form
of network support, and many
speak SQL; both of these fea-
tures are left unexplored in these
reviews because the typical COM-
PUTE reader is a hobbyist or
small-business person on a single-
user system.
Access, FoxPro. Paradox, and
Superbase ail have programming
languages of their own. Every
one of them is expensive, and eve-
ry one of them is a stunning
achievement. At list pnce they're
bargains; at the competitive up-
grade prices, they're steals. You
can't go wrong with any of them.

The middle tier is less predict-
able. Its products range wildly in
feature combinations; among
them, Approach and FileMaker
Pro are out-and-out winners.
If your needs are simpler, you'll
want to take a look at the sidebar
describing Instant Database
from Asymetrix, Data Manager
from Timeworks, and FormWorx
from PowerUp, They taste great,
and they're less filling price-
wise. Another sidebar covers
CA-dBFast 2.0, a product that
shipped too late for coverage in
the Test Lab regular reviews.
Some of the products covered
in this Test Lab support an image
data type for fields, but OLE gets
extra credit because it can han-
dle any data type, at no cost to
the DBMS. Interestingly, few use
the common file open dialog
Microsoft began promoting with
Windows 3,0, and too few sup-
port data entry masks to restrict
input to, say, a phone number or
Social Security number style.
All trends point upward; this is
a healthy and impressive bunch.
Installation programs are all com-
petent at the very least, although
some are called INSTALL, EXE
instead of the more standard SET-
UPEXE and some don't show
available and required disk
space. A goodly number offer
something besides a full, default
installation: sometimes a minimal
installation and sometimes a cus-
tom installation.
All can print a report to a text
file if you install the Windows
Generic print driver, but that's a
pain, I looked for plain text output
without Generic. All of them have
calculated fields, and all but one
employ the standard Windows
help system, Paradox uses the
help system most effectively, with
a number of well-thought-out visu-
al metaphors that show we are
only now beginning to understand
the efficacy of hypermedia.
If you've been thinking about
graduating from Cardfile, go for
it. The game has begun.

ACEFILE 2D
AceFile is a midrange product
with a broad, sliailow feature set.
In addition to using dBASE III
PLUS data files as its native for-
mat, AceFile boasts graphing, a
dialer, and a rudinnentary mail-
merge facility witfi a text editor.
Because of its shallow feature
set. AceFile is pretty easy to
learn. Some things are a little awk-
ward, such as its handling of
index files, but if AceFile is your
first database, these considera-
tions are small and shouldn't
affect your enjoyment, I find
AceFile fairiy snappy, and it would
be an even better performer were
it not for bad handling of screen
redraws. There's way too much flick-
er when AceFile launches, when
you quit, and when you enter da-
ta or scroll through records in a
multiwindow application.
AceFile's idea of a complete
database application is a "view
set," a file containing the arrange-
ment of windows, databases,
and relationships in the applica-
tion. Nowhere nearly as cohesive
as, say, the equivalent applica-
tion in Access or Superbase, but
it gets the job done.
While there's no programming
language, AceFile has a wide va-
riety of very useful functions you
can embed in forms and reports;
reports are especially flexible. It
also has a macro facility, so put-
ting together a view set as a turn-
key application is straightforward
with only a little study.
The graph module is flexible
and has a number of charts. It's
not quite as visual as I'd like, tak-
ing a fill-in-the-forms approach
when direct manipulation would
be more desirable. For example,
you type in numbers for the
angle and tilt of a 3-D pie chart,
rather than rotating a model of the
chart in realtime.
Somehow I feel that the whole
is less than the sum of its parts.
1 probably wouldn't have noticed
this had I not dealt with such seam-
lessly integrated masterworks as
Access and Superbase. For ex-
ample, you can't have parts of
several related files show up in
the same window. Each must
occupy its own window, leading
to rather creative use of tiling in
the sample applications.
The manual is pretty good.

although, despite a longish index,
I was stymied when I tried to find
out whether the program has
memo fields. I couldn't find memo
or field types \n the index, AceFile
does indeed support memo
fields, by the way, because it uses
dBASE files as its native format,
If you need a broad range of fea-
tures in one box with a moderate
price, AceFile is a good choice.

APPROACH 2i) FOR
WINDOWS
Of all the "easy" Windows data-
base managers in this roundup. Ap-
proach and FileMaker Pro seem
the best to me. While Approach
lacks a programming language, it
lets you create impressive turnkey
applications very quickly.
Approach impressed me right
from the start. Its toolbar contains
only the most-used features, so I
found it the easiest to learn. Its
menus are perhaps the best
designed of any in the products
I used, leaving the toolbar for
what it's supposed to do —
provide quick access to the
actions that you'll perform most
frequently. And let's face it: Icons
are helpful if you already know
what they mean; however, having
to learn 30 or 40 of them can
slow you down, even if you're the

most determined power user,
I found the manuals elegant
and useful, with a well-written
tutorial. Unlike, say, FoxPro's big
tutorial, which targets experi-
enced Xbase programmers who
want to learn FoxPro's special
features, the Approach tutorial
teaches you both the product
and database management at
the same time.
The Approach user's guide is
equally good, making its few omis-
sions stand out. According to the
box. Approach allows you to "be-
come productive instantly by
providing turnkey business
templates, " but I couldn't find
templates in the index.
This product's online help is
fine, but what it calls an index is
actually a table of contents. My
biggest complaint about help is
that you usually can't get it from
inside a dialog, such as when
you're adding a field to the data-
base structure. The documenta-
tion on importing and exporting
data is the best I saw with any
DBIvlS, The few connplaints I
have are minor ones about an oth-
erwise superb product.
Approach was one of the first
significant database managers
for Windows 3.x, and it shows, I
found the drawing tools parttcular-
18 COMPUTE AUGUST 1993
ly good, and they have a Group/
Ungroup feature, which lets you
fuse objects together to form a
Sfngle selectable unit. Need form
letters? With Approach they're
easy, and they're built right into
the product. Creating a macro is
a snap, although macros are
somewhat limited and don't run
very fast. The query mechanism
IS so simple that it doesn't even
have a separate name; it's just an
extension of the Find dialog you'll
see in most Windows applica-
tions. While Access makes a big
deal about its dynasets.
Approach has had a similar fea-
ture for a long time. With
Approach, when you create a
report, you can edit the records
output by the report. They aren't
called dynasets, but the effect is
similar.
An Approach application is
held together by a "view" file, and
view files do some amazing
things. For example. Approach
can use both Paradox and
dBASE as native file formats with-
out translation. Neither has a
JA-DBFAST 2.0
A few months ago, I questioned Com-
puter Associates' purchase of both
Clipper, a DOS Xbase compiler, and
dBFast, a Windows compiler. Since
they had different extensions to the
dBASE language, I implied that per-
haps CA had gotten in over its head.
I'm happy to be proved wrong by
release 2.0 of CA-dBFast— glorious-
ly wrong. (Release 2.0 arrived too
late for regular coverage. This pre-
liminary look is based on just one
day of examination, so bear In mind
that it's not an exhaustive look. The
dBASE compatibility helped me in
this regard, because I was able to
run a goodly amount of vanilla III
PLUS code through,)
Like Clipper, dBFast is an implem-
entation of the dBASE 111 PLUS
language. Wisely, CA has given
dBFast a complete development
environment with a multiwindow
editor, a debugger, and visual report
and form designers. The extensions
to dBASE III PLUS are numerous-
more than 350 of them, by my
count. Many of them echo similar
extensions to Clipper (array-handling
routines, conditional compilation,
binary file I/O), making it clear that
CA is heading in the same direction
with both products.
Like FoxPro. CA-dBFast lets you
create true Windows applications in
dBASE style, Unlii^e FoxPro, CA-
dBFast gives you true EXE file crea-
tion at a price that competes favora-
bly with those of Borland and Micro-
soft language products: S550, ver-
sus about $1,500 with FoxPro. The
EXEs require some frightening over-
head — a simple one was 500K — but
the productivity gains are worth it,
Version 1 ,0 was beset with prot)-
lems and was so delicate that it
often couldn't run even generic
dBASE code. Happily, this seems to
be a thing of the past, CA-dBFast 2.0
has some incredible language exten-
sions, a terrific language reference
that's chock-full of examples, and a
good debugger at a very competi-
tive price. It has a bright future.

DATAEASE EXPRESS

DataEase is a powerful develop-
ment environment for nonprogram-
mers, though it has significant
flaws. Designed more for corpo-
rations than for individuals, it's
built on a rock-solid data engine
with numerous connections to
minicomputer and mainframe
database managers.
While I found it more complicat-
ed than the other nonprogramma-
ble database managers, I also
found that it can do substantially
more in certain areas: queries, view-
ing the data in different form con-
figurations, and mainframe que-
ries. Another feature geared more
toward the corporate user, its use

of style sheets on forms, allows
you to standardize on one or more
visual themes.
Some things just didn't sit well
with me. For example, to create a
table (database file), you have to
choose File/New/Form and
choose <NewTable> in the Select
a Database Table column. It nev-
er occurred to me to look there
because most DBfvlSs keep the
form and table separate.
While most of the packages in
this Test Lab offer a good number
of sample applications, DataEase
wins for real-life usability. You can
modify the Club ParaDease and
project manager sample apps for
use in your own business, where-
as the sample appiications that
come with other products would
be better thought of as starting
points. The DataEase sample
apps show a weakness of the over-
all package, a cluttered design
and overenthusiastic use of color
that I found somewhat confusing.
Compounding this, the sample
apps seem to have been created
for a Super VGA system:, so the
text label Appo/n/menf became Ap-
pointmen and DayMinder Person-
al Plannerwas truncated to DayMin-
der Personal Pla. Also, the sample
application uses teensy fonts in
some areas that users with less
than perfect vision will find impos-
sible to read.
DataEase employs my favorite
catalog approach of the bunch,
giving it the edge for team pro-
jects. The main window of the
catalog is collapsible, like an
outliner, and you can double-
click on its elements to go direct-
ly to them. Its support of graph-
ics is a little iffy, requiring you to
enter a filename for each graph-
ic: you can't just paste it in from
the Windows Clipboard. On the
other hand, it supports all major
graphics file types: Windows
bitmap. Encapsulated PostScript,
CompuServe GIF, Paintbrush
PCX. Targa, TIFF, and Windows
Ivletafile.
DataEase wouldn't be my first
choice for home or small busi-
ness use. It's sufficiently eccen-
tric and complex to learn that I'd
rather go all the way and learn
Access or Paradox.

FILEIVIAKER PRO 2.0
FOR WINDOWS
From the manual to ttie sample ap-
plications to the software itself,
this version of FileMaker Pro ooz-
es quality.
It's one of the first Windows
products released by Claris, a
wholly owned subsidiary
of . . . Apple! Yes, the people
who created the fvlacintosh final-
ly wised up and started cashing
in on the Windows market, which
they indirectly helped to create.
Filefvlaker Pro has attracted a iot
of attention and deserves it.
While you can exchange files be-
tween the Macintosh and Win-
dows versions of FileMaker Pro,
this does not feel like a soulless
ripoff. FileMaker Pro is one of the
best examples around of how to
create a great Windows product.
Miscues are few and far be-
tween, One of them is that there
are two kinds of scroll bars, the
standard Windows variety and a
homegrown one. The radio but-
tons aren't factory issue, either.
This is no doubt an artifact of the
common code base the program
shares with the Macintosh ver-
sion, but these features lumped
out at me. And you can't get help
from within dialogs, a feature I
missed greatly but was able to do
without because of the program's
amazing design. The help system
is a model for Windows applica-
tions — another surprise given its
ancestry.
With FileMaker Pro, creating a
database is easier than with any

other product in this Test Lab. An
Options dialog for each field
type allows you to override the sen-
sibly chosen defaults, and it
makes such tasks as defining the
field as unique or uppercase
downright simple. I missed logi-
cal field types, but you can get
the same effect by making the
field a check box— arguably a bet-
ter solution. Choosing a font
brings up a visual representation
of all the fonts on your system;
I've never seen this in a Windows
product, and it's a godsend.
The Find dialog is secretly
also a query mechanism, used to
select records for reports. This is
so subtly integrated into the pro-
gram that there isn't even a sec-
tion on reports in the manual.
There is a macro facility that's
limited but easy to use. As a pro-
grammer, I found it limiting, but
as a user in need of slapping
together a database application
fast, I found it agreeable. File-

Maker Pro reads all the major
graphics file types and then
some, probably more than any oth-
er DBMS in this roundup. The sam-
ple applications have their own
manual, so you don't have to doc-
ument or create them from start,
Its price puts FileMaker Pro up
with the high-end programmable
database managers, but I think
it's justified by the sheer ele-
gance of its implementation. It
adds up to a brief learning curve
married to an ample feature set —
two qualities that appear often in
Windows products but seldom in
the same one.

MICROSOFT ACCESS
1.0
Access typifies the worst and the
best of Windows. It's big, slow
even on a four-meg 486SX ma-
chine, and complicated. It's also
a masterpiece, an instant classic
of Windows design.
What makes Access special is
the depth, richness, and integra-
tion of its features. You can save
a form as a report. You can edit
the results of a query exactly as
if you were using the data itself.
Windows drag-and-drop features
are used extensively. And often,
a feature is so obvious that you'll
use it without thinking about it
because you're simply not accus-
tomed to such an intensely visual
environment. The manuals and
sample applications look fine and
do an amazingly good job for a
1.0 product.
Rough edges in this package
are evident but few: The manual
slips and calls the program
Cirrus, its code name under devel-
opment; I noticed a page refer-
ence of ??? where the writer had
neglected to fill in the number:
and some simple tasks require a
dip into the Access Basic pro-
gramming language.
I don't see this as an easy
database manager, but the pro-
gram's incredible power yields
more per hour of learning than
any Windows product I've ever
seen. After a few serious months
learning Access, you could cre-
ate very sophisticated Windows

applications in very few billable
hours. It has the best macro
facility of any of the databases
reviewed in this Test Lab round-
up, and when I checked Compu-
Serve, I noticed that a fair num-
ber of nonprogrammers are
doing the job of programmers
using macros alone.
Access Basic is a strong,
capable language, but you won't
learn it fast. It looks a lot like Vis-
ual Basic, but the two aren't com-
patible. If you ve never used Vis-
ual Basic. Access Basic will be a
real stretch. There's an extensive,
weil-written tutorial to help you
bridge the gap.
Not only can Access import
data from a respectable variety of
sources, but it can also "attach"
dBASE and Paradox files and
indexes. Attached files are left in
their original formats, but they act
just like they're native to Access.
It's faster if you import them, but
if you're not willing to entrust your
current data exclusively to
Access, you can have it both
ways. Keep in mind, however,
that importing has a hidden
price. Access stores everything —
forms, data, program code,
reports, macros, queries— in a sin-
gle file. So if you're developing
Access applications for clients off-
site, there's no comfortable way
to update the code portion of a
database without destroying the
existing data,
I must admit that my Windows
system wasn't comfortable with
only four megabytes of memory.
IVIicrosoft optimistically lists two
megs as the minimum working
configuration, but don't even
think about it. Be willing to accept
the reality that Access is a
resource hog.
Access is a thrilling first
release. Some features, such as
data entry validation, aren't as pol-
ished as they could be. IVIost oth-
ers, such as its macro facility,
drag-and-drop user interface,
and Basic language implementa-
tion, have already made it to the
head of the class. If you're willing
to spend some time with the man-
ual, Access will handle any data-
base management task you
throw at it,

PARADOX 1.0
FOR WINDOWS
Paradox gives you the best of
both worlds: the assured maturity
of a product created by an
experienced design and documen-
tation team and the freshness of a
1 .0 version. Although Paradox for
DOS has been around for years
now, the Windows version is a com-
plete rewrite with only data compat-
ibility. Paradox is an awesome
development environment.
Paradox, like Access, is billed
as being easy enough for an end
user but powerful enough for the
most experienced developer, I
don't believe the former, but the lat-
ter is true in spades. If you want to
make full use of Paradox, you'll
have to learn at least some of its
ObjectPAL language, but your ef-
forts will be rewarded handsomely,
Paradox, long famous for its
query mechanism, is even better
as a Windows product, allowing

result oi some computation, usually
based on otiier fields, Calculated fields
require no space in a file because their

catalog. An idea gaining currency in
ttie last few years, tfie catalog is a way
to store information about a single data-
base application— the files it uses, the
way data Is stored, the program code,
and the visual attributes of the applica-
tion's user interface.
counter data type. A number that
increments automatically when a record
is added: normally, counter fields can't
be edited. Useful for generating serial

anteeing that no record in the database
IS identical to another record.
DBMS. DataBase h/anagement Sys-

here. This is different from a database,
which Is usually information that can be
stored in categories, such as names, ad-

databases are being called tables, to

the database managers in this roundup
allow the use of built-in numeric and text
manipulators such as SUU{). UPPER-
CASE! ), and AVERAGEO: these
are called functions. Sometimes the func-
tions can be used only in forms, some-
times only in reports, but usually in both.
Functions work just like spreadstieet func-
tions and can usually be similarly built
up into complex expressions.
index. Database records are stored on
disk and copied into faster RAM only one
at a time, while a ^ecord is being edited.
An index contains a copy of a selected
field from all the records in the database
in RAI\,1, making it possible to navigate
through the database in an ordered fash-
ion without sorting the database.
macro. A macro contains one or more
memorized actions, such as positioning
to the next record or choosing an item
from a menu. Less complicated than a
prtjgramming language but also less use-
ful, macros allow the creation of turnkey
applications by nonexperts.
memo field, t^ost fields in a database
are of fixed size— a 30-character last
name, an eight-byte numeric field, a two-
byte time field, and so on. Memo fields
let you store arbitrary amounts of infor-
mation, usually textual, without wasting
space on the disk for records that don't
have sjch information. Useful for record-
ing patient histories, special directions,
and sometimes more exotic values like
images or sound.
query. A way of finding records that
meet selected criteria so a report can be
printed. Queries are like filters except
that they can be saved and quickly re-
trieved for later use. Sometimes called
fillers,
table. Information stored in row-and-
column format, sometimes called a da-
tabase. Columns are sometimes called
fields. The rows are called records. The
old term for table is database, but that's
slowly going out of style.

ObjectPAL is a killer language.
Borland made the right choice in
creating a new language that can't
use programs created for its DOS
predecessor, despite the pain it
will cause those with a big invest-

its reference manual is by far the
best of the bunch. You can learn

FormWorx 2.0 for Windows
It would be wrong to call 'hese prod-
ucts fuH-festured database managers,
but they're handy tools in the fight
against data glut.
FornnWorx 2.0 for Windows (there's
a nearly identical, compatible DOS ver-
sion) is an intriguing package designed
specifically for the creation of printed
forms such as purchase orders, past-
due notices, credit card applications,
fax cover sheets, sales reports, and so
forth. It also comes with a companion
product named Fill & File, which ef-
fectively turns FormWorx into an in-
dexed database manager, complete
with table lookups, default data entry val-
ues, calculated fields, search and re-
place, and customized prompts.
As you might imagine, FormWorx is
heavy on border patterns, variable
units of measurement, alignment
tools, and so on. You can ceate librar-
ies of form objects or use the supplied
ones. Hidden in the bacl< of the book
is an invaluable discussion of how to
use LaserJet output and manipulate the
files from other languages (you can
send the form out as an HP macro, a
customized set of commands proc-
essed directly by the laser printer).
To ease form creation, there's a
palette of "data objects," which con-
strain data entry to the formats for Amer-
ican currency, numbers, dates, times,
five- and nine-digit ZIP codes, and sev-
en- and ten-digit phone numbers. You
can create custom input masks for
those that aren't covered— for example.
Social Security numbers, foreign tele-
phone numbers, or European date
styles. In all, FormWorx is a bargain
and, with a library of 600 forms, may be
less expensive than hiring an artist to
rustle up even one simple form.

Instant Database 2.0
Instant Database 2,0 comes from
Asymetrix, the company that
brought you ToolBook. Written in Tool-
Book, Instant Database exhibits
some of that product's slowness, but
not unbearably so. Instant Database
has an 80-page manual that manag-
es to cover most issues, but it leaves
a few of them, such as the dialer, woe-
fully short of full coverage.
Instant Database is just that; you
can create a database structure in a
very few minutes just by drawing the
fields onto a blank form. You don't
bother with giving the fields types,
such as number or text, and you
don't even type in a maximum
length, as is customary with most oth-
er database managers. The result is
a database that runs plenty fast with
up to a few thousand records but
then bogs down quickly. The report
mechanism is quite limited, but it has
a few useful options such as one to
four columns, rudimentary mailing la-
bel support, and conditional expres-
sions. This last option appears to be
quite powerful.
If you're interested in multimedia
computing, take note: With Instant Da-
tabase, you can add animation,
graphics, Asymetrix fvlediaBlitz
scores. Wave audio, IvllDI audio,
and digital video files to the record
fields. The product also supports IVII-
crosoft Video for Windows.
If flexibility is less important to you
than convenience, Instant Database,
with 1 4 gorgeous but limited sample
applications, may be for you.

For S60, you get a DBtyiS that com-

While it's not possible for you to cre-

miracle of miracles— they're actual-

to be a great leap forward in user
interface technology, it typifies what
Data tvfanager is so good at; getting
the job done.
Timeworks' forms don't support
data entry masks such as A" to
force the input to uppercase in a
text field. While I'd like that feature
because of the flexibility it adds.
Data fi4anager instead lets you
bring up a Field Formatting dialog
box, and here's where you see
some of the program's flexibility It al-
lows you to force text to uppercase,
lowercase, or initial capital (very
handy for entering names, unless it's
one like deForest); round numbers
up or down or truncate them; limit
numeric and date values to a certain
range; and set the precision for num-
bers. Sure, it does mean that I can't
create a data entry mask for, say, So-
cial Security numbers, but it lets me
do the most common tasks easily
Calculated fields and reports
make use of an expression builder
that works in an easy, visual Win-
dows fashion. Reports have all the
standard features and, while there
are no presets for Avery labels, the
instructions for creating labels are
crystal-clear. Tech support was not
hard to reach — amazing for such an
inexpensive product,
At $60, Data fvlanager is a steal
and quite good enough for most ap-
plications.

SUPERBASE
I
SUPERBASE 2.0
Let's get one thing clear about
Superbase from the start. You
must know BASIC to use it prop-
erly. If you know BASIC, good,
because the Superbase dialect Is
a good one. Superbase Is a
mature product that's gotten
rave reviews, and it deserves
them. It's fast, easy to program,
and wonderfully documented,
and it comes with some bonus
development tools that will make
you even more productive.
Superbase has all the bells
and whistles you expect from a
high-end Windows database
manager: easy forms design, a
complete and well-integrated
query-by-examples mechanism,
default creation of several dif-
ferent kinds of reports, a dialog
editor, and a macro recorder.
The macro recorder is ingenious
in that it generates code in
SBL, Superbase's version of
BASIC.
Creating applications with
Superbase is even easier than
with Access. For example, you
can attach SBL code directly to
a button (or list box or whatever),
whereas in Access you must
attach the code to a macro and
then run the macro from the but-
ton. I also like SBL better than
Access Basic because it's far
closer to the spirit of BASIC. Soft-
ware Publishing intimates in its
literature that it will begin to

make SBL more like Access Ba-
sic, but I hope the plans don't
pan out. While Access is quite
powerful, it's harder to learn than
Superbase. If you've been de-
veloping applications in, say,
PowerBASIC or QuickBASiC as
opposed to Visual Basic,
Superbase will make more sense
to you. There's also a big library
of canned SBL routines, so you
could well put together a com-
plete app with nothing more than
(hose and some glue code.
Superbase is very fast, too —
one of the fastest of the DBMSs
in this group. You can scroll
through complicated forms even
faster than with some DOS data
managers.
I do have a few complaints,
though. I found that dBASE
memo fields don't import proper-
ly (they become ten-character
text fields), and L could find no
documentation addressing the
pie rdil view Draw .Di;(irii; Mlilitifs (Iptions Help
issue. The SBL reference manu-
al, chock-full of useful example
code, isn't Indexed, And I began
to realize that the reason Super-
base relies so heavily on what it
calls validation formulas (which
check to see whether you've
entered information into a field
properly) is that it doesn't have
data entry masks, also known as
picture fields.
But you can't go wrong with
Superbase, especially if you
have experience as a BASIC
programmer. Like dBASE in its
heyday, Superbase is a full data
management system with an
easy-to-learn, state-of-the-art
script language

TECHNOLOGY UPDATE
How to get surround
sound without buying
the theater. . .
An amazing new surround sound decoder turns your
existing stereo into a five channel home theater.
B\/ Cluick Anton
As much as I love reiUing vidoos, it's just
not the same as seeing a inm-ie in a
t theater. I remember the first time ! saw
Top Gun. I nearlv jumped out of my sent when
tlic planes flew overhead. One of the rensuns
movies seem so real is because they use sur-
round sound to make it seem like you're ac-
tually there. Now, an
incredible new de\'ice
lets you use your
stereo receiver to gel
that same surround
sound in your home.
It takes more than
just four speakers to
get surround sound.
You need to have
some wav of separat-
ing the signals. The
new QI>1 Series II de-
coder does just that,
and in a revolutionarv
way that rivals the
best Dolby Pro-Logic
and THX Systems
available.
Wins over critics.
Noted audio critic,
Len Feldman, review-
ed the QD-1 for the
September issue of
Audio Magaziiw. He
concluded that
■'...the QD-l pro-
duced a complete!}'
accurate and realis-
tic surround sound
experience from a va-
riety of videotapes
and laser discs with Dolbv surroLmd en
coding.,, the QD-1 delivers home theater soinid
the wav it was nieant to be lieard."
Brealtthrougli 'L minus R.'
Back in the 1960's, Dvnaco dis-
covered that in addition to the
right and left channels, a "dif-
ference" signal existed in a
stereo recording, and aptly
named it "L minus R." The QD-1 is able to de-
code Dolby Surround
signals in a videotape
or a laser disc because
those spatial and
depth cues have been
matrixed into the "L
minus R" portion of
the stereo soundtrack.
It does so passi\elv,
with no signal pro-
cessing. What's more
amazing, the QD-1 us-
es your main stereo
amp to amplify the
rear channels. You do
not need any addi-
tional amplifiers!
Concert hail sound.
TheQD-l also decodes
the ambience found in
all musical record-
ings. This sense of
space, or concert
hall acoustics Is pre-
sent in all CDs and
cassettes, especiailv
live recordings. John
Sunier of Auiiiophilc
Eiiition, a nationally
svndicated radio pro-
gram, says "If you're
a surround sound
buff who loves to listen to music, you'll find
this S79 passive black box superior to e\'en the
S3000 TIIX or Dolby Pro-Logic processor,"
The Secret of Surround Sound
Surround sound has become the rage of the
■go's because it adds "depth" to stereo sound,
giving you tfie home ttieater experience. Simply
slated, it makes you lee! like you're actually at a
concert or a movie theater,
To "fill a room" with sound you need more
than the two channels. And that's the beauty of
the Dynaco OO-i, it provides five channels from
any two channel stereo or TV.
Dynaco offers rear chan nei speakers specif-
ically designed !o integrate with the QD-1 de-
coder. You may also need our center channel
speaker, the Ai o-v. if your tv/o front speakers are
more than eight feet apart. Adding this fifth
speaker, or center channel, helps keep dialogue
and importani localization cues centered. So you
don'l need to spend thousands
of dollars to enjoy sur-
round sound. ^- J A 1^^
THE PASSIVE ADVANTAGE
Passive. The OD-1 is passive, meaning it
requires no AC current. It actually sounds
better than active decoders, producing more clar-
ity, more detail, no noise, a greater
sense of space, and zero
distortion, This superior
passive system is a break-
through unique to Dynaco.
The QD-1 decoder makes your
movies come to life. Surround
sound brings the theater experi-
ence home to you.
Active. All Dolby Pro-Logic decoders
(stand-alone or built-in units) are active.
This means they decode and amplify the
signal electronically. The active way
induces noise and distortion, hindering
the home theater experience.
This is an example where
"more is less." Spending
thousands on an active sys-
tem will not give you the
performance of the QD-i.
Quicl( and easy installation. Mook up is
easy. The QD-1 connects to the speaker out-
puts on your amp. Tlie speaker leads then run
to each of your four (or fi\'e) speakers. The
rear channel speakers mav be small; we
recommend the
AVV-ts at S99 a
pair. They come
with mounting
hardware, a key-
hole slot for flush
mounting, and
have an attrac-
tive all-weather _. ,,,, , ^ , ,

Ergonomics helps
Microsoft's
mouse ease wrist
strain.
Of Mice and People
Both Microsoft and Logitech
have chosen this summer to in-
troduce new ergonomically de-
signed mice. Logitech, maker
of the Kidz Mouse and mil-
lions of OEM mice, made
headlines two years ago with
its new line of built-for-comfort
mice. Its new three-button
cordless mouse fits the palm
pleasantly while substituting
low-energy radio waves for
the usual desk-encompassing
tangle of mouse cable. The
mouse can be sensed by its
receiver over a range of six
feel. Users can program the
driver to interpret the middle
button as a double click and
the third button as a keypress
(the default is the Esc key).
The mouse is scheduled for re-
lease in August. Its suggest-
ed retail price is S149.
Microsoft, also vy-
ing for the
Order of the
Palm", intro-
duced its latest ver-
sion of one of the
most successful ro-
dents since Disney's. Its first
redesign in six years boasts a
more comfortable angle
(while retaining ambidextrous
operation), a thumb grip, and
a weight over the ball for en-
hanced traction. The new
mouse driver (version 9) pro-
vides many improvements to
ease working in Windows, in-
cluding an automatic snap to
the default button in a dialog
box, a magnifier for the two
square inches of screen near-
est the mouse pointer, and a
wrap feature that moves the
mouse pointer to the opposite
side of the screen when you
move past the edge. The se-
rial version lists for $109.00
and the bus version for
$125.00. The software's sug-
gested retail price is S19.95.
New Deal
Compaq Computer and Micro-
soft have formed the Frontline
Partnership, in which both
companies will work together
to develop products "that are
the easiest to use and the sim-
plest to install, with the best
performance and value in the
industry" — including desktop
PCs, portable PCs. docking
stations, and hand-held com-
puters, according to a press
release issued by Compaq.
One area that the two com-
panies plan to promote heavi-
ly to PC hardware, software,
and peripherals industries is
the new Plug and Play ISA
specification codeveloped by
Compaq, Microsoft, Intel, and
several other companies. The
goal of Plug and Play is to cre-
ate automatically self-configur-
ing hardware and software.
Easy Labels
Whether you want one label
or a hundred, forget your print-
er. The LabelWriter II is a hard-
ware/software combo that
plugs into your computer's se-
rial port, ready to produce la-
bels in any quantity instantane-
ously Running as a TSR pro-
gram (DOS version) or a full-
featured Windows application
(Windows version), the Label-
Writer 11 software gives you a
number of options for creative
label making, including scala-
ble fonts and the ability to mix
font sizes and styles on a line-
by-line basis. Other features
let you create time-saving la-
bel templates, print POSTNET
postal bar codes, and view
WYSIWYG displays of each la-
bel before printing.
LabelWriter II uses a 1-
inch printhead and retails for
S249.95. The LabelWriter II
Plus uses a ZV-i-inch print-

Photo CD Catalog
Searching through tiny photo-
graphs in a big stock-photo
book is the old way of doing
things, now that Kodak's new
Photo CD technology allows
high-resolution 35-mm film im-
ages to be stored on a CD for
review on a computer or TV
screen. And Kodak has
formed a joint relationship
with L. A. -based Westlight,
one of the largest stock-pho-
to agencies in the world, to
market its new Kodak Photo
CD Catalog, which allows
Westlight's photos to be
viewed and manipulated on a
Mac or PC.
Ad agencies, publishers,
or anyone else who uses
stock photos in creative work
"can review and discuss
each photo in a conference
room instead of crowding
around a light table." says
Westlight's founder, Craig Aur-
ness. And once a photo's se-

Your Health on a Data Card
The newest thing to hit the
healthcare industry is the Op-
tical Card System, developed
by Canon, that serves as a
portable patient record The
credit card-sized OC20 opti-
cal card can store the equiv-
alent of 1600 pages of text. In-
formation is written to the
card and read by a read/
write drive unit, the RW20,
that connects to standard
IBM PC/AT and compatible
computers.
Healthcare-system adminis-
trators, insurers, and provid-
ers currently conducting pilot
projects with the card say it
should help head off
healthcare fraud and elimi-
nate redundant medical pro-
cedures — and therefore help
contain costs. Also, you can
expect improvements in the
quality of your care "when a
comprehensive, accurate, up-
to-date medical summary —
including full medical history
and drug therapy — is immedi-
ately available to a doctor dur-
ing consultation." according
to a press release issued by
Canon. But healthcare is only
the first application for the
card.
Possible uses for optical da-
ta cards as storage media
are almost unlimited.
It's Virtually Golf

real, but you'll only think
you're playing 18 holes in Ha-
waii when you swing a club
on this virtual-reality golf
course, where you'll see exact-
ly where your ball would
land — fairway, green, hazard,
rough, trees — if you were play-

Music Man
Years ago I ran across a BA-
SIC program that would turn a
PC keyboard into a simple or-
gan keyboard. Can you show
me how that's done?
WILLIAM TAYLOR
LOS ANGELES, CA
Here 's a very simple record-
and-play-back program that
turns your keys A-' (the sec-
ond tier of keys on a standard
keyboard) Into the white keys
on a piano. It keeps track of
the notes you play and allows
you to play them back at will.
You might want to alter tlw
program to request a file-
name for your recording, be-
cause the way the program is
written, you'll overwrite your re-
cording each time you play.
It works better if you play
staccato, because the operat-
ing system's debounce rou-
tine causes the note to be
turned off and then back on
as you hold the key down.
We attempted an alternative
version using the ON KEY com-
mand, which worked very well
but limited the keyboard to 1 1
keys. With this version of the
program, you can add to your
keyboard whenever you like.

Old Times
I read somewhere that you
can change the time and
date of a file with some para-
meter of the Copy command.
I can't remember where I
read it. Do you know the com-
mand syntax?
WALTER GREENWOOD
SANTA ROSA, CA
This technique was covered in
the March 1993 'Tips &
Tools" column. Use the Copy
command with concatenation.
If you want to change the time
and date to something other
than the current time and
date, use the Time and Date
commands first to change
these settings in DOS. Then,
use this command.
COPY FILENAME + ,,
This will change the file's
time and date stamp to what-
ever the computer's current
time and date is.
Norton Utilities has the com-
mand FD that will allow you
to set any date you wish
for a file.
There are ways to access
the directory listing directly
with Debug. Each directory list-
ing is exactly 32 bytes long.
Bytes 22-23 are the time and
24-25 are the date. It's a little
difficult to figure out the coding
of these bytes, but if you're ad-
venturous, you can alter them
to reflect times and dates that
can't exist, such as the time
25:63:62 on the 31st day of
the 13th month.
We only mention Debug as
an option because DOS's com-
mand interpreter (the spoil-
sport) prevents you from enter-
ing impossible times and
dates from the command line.
Is There a DR in the DOS?
You see the statement "Must
have DOS 3.0 or higher" eve-
rywhere. I have DR DOS 6.0.
Does that fulfill the require-
ment? What's the difference
between MS-DOS 5,0 and DR
DOS 6.0? Also, where can I
get a BASIC language (GW-
BASIC or QBASIC)?
R G DINGWALL
MEADViEW. AZ
DR DOS 6.0 should perform
properly with any program
that requires MS-DOS 3.0 or
higher The main difference be-
tween DR DOS and MS-DOS
IS the collection of utilities you
receive with each one. One of
the advantages of MS-DOS is
that you get a free BASIC pro-
gramming language with it.
Bill Gates, the cofounder of Mi-
crosoft, got his start writing BA
SICs for microcomputers, and
he 's never forgotten his roots.
Gary Kildall, the founder of Dig-
ital Research, got his start cre-
ating microcomputer operat-
ing systems.
The only way you could get
GW-BASIC or OB AS 10 with-
out purchasing a Microsoft ver-
sion of DOS would be by com-
mitting a federal crime — cop-
ying one of them from some-
one else's DOS. We don't ad-
vise that you do that. If you

FEEDBACK
need a BASIC, "Feedback" 's recom-
mendation would be to purctiase Quick-
BASIC 4.5. PowerBasic Is supposed to
tiave a new version out, but as of tliis
writing, we Inaven't seen it. True BASIC
is anottier contender. The ciieapest
way to get a BASIC would be to pur-
chase and install Microsoft DOS 6.0.
More Density Problems
My hotne computer has a double-den-
sity disk drive. Wlien I purciiased
some programs on higln-density disks,
I was told tliat I could install tliem on a
computer with a high-density drive and
then recopy them to double-density
disks so my computer could read
them. 1 have tried this with several pro-
grams, but it doesn't seem to work. I
get an error message from DOS, such
as Data error reading drive A: or Sec-
tor not found: error reading drive A:.\s
there a way to run high-density disks
on my double-density drive? Is there
something wrong with my drive?
MICHAEL STAUFFER
ALLEN, WY
Ttie answer to your last question is
tiiat there's probably nothing wrong
with your disk drive. We suspect tliat
you're using disks formatted as double-
density in high-density disk drives.
These drives leave narrow tracks that
the relatively coarser heads in double-
density drives have trouble locating
and reading. Format some double-den-
sity floppies in your computer, and
then copy the files to them on a com-
puter with a high-density drive. If this
doesn't work, there's a possibility that
your drive is out of alignment and
will require the attention of a trained
technician.
in answer to your penultimate ques-
tion, you can 't read high-density disks
with your double-density drive.
Do you have a question about hardware
or software? Or have you discovered
something that could help other PC us-
ers? If so, we want to hear from you.

s a student at the TCSN Academy, you custom-
design and fly unique combat, rescue, and
search and retrieval missions from the
CyberSchool's holodeck console. In the Wing
Commander^' tradition, the game features a
dynamic musical score, improved rendered, bit-mapped
graphics, and a dazzling array of customizing options. But
Wing Commander Academy isn't another cinematic extrava-

♦ Custom-design a variety of missions that match your skill level as you place
fighters, capital ships, data pods and ejected pilots - up to 10 in each of the
four action spheres.
♦ Save up to 24 games to disk and trade with your friends or upload them to
bulletin boards to challenge others.
♦ Request random missions where each action sphere yields an unknown num-
ber of enemy ships with pilots of varying skill levels.
♦ Climb into the cockpits of the new Confederation Wraith or Kilrathi Jratbek
fighters for a new combat experience. /
♦ Select a cybernet wingman - from a frightened cadet to a hotshot veteran.
♦ Fly from the cockpit view or try the chase-plane view for a new perspective
on the dogfighting action.

♦ Engage the "Wave" - a dogfighting marathon with 15 progressively difficult
levels of attacking ships - including three flights of fighters in each level.
♦ Build missions so tough that even our professional Wing Commander pilots
can't survive.

FLIGHT ASSIGNMENT: ATP
A greafiijying sim ula tion for a
frustration- free aviation
experience!
For fifteen years our flight
simulations have won acclaim for
their dazzling displays of techni-
cal wizardry. Now we're using
the computer medium to provide
a satisfying introduction to the
world of aviation. You might say
that Flight Assignment: ATP
revision D represents the current
state of the art with a user-
friendly twist.
ATP External View
Six months of intensive real-
world flying helped our engineers
ing staff refine ATP's flight
characteristics and joystick
interface, making the simulation
both easier and more realistic to
fly. ATP combines exceptional
responsivenes§.with an easj^tg..
read flight manual to give you a
great flying experience.
While you're getting comfortable
at the controls, let ATP's auto-
flight mode give you a relaxed
introduction to commercial
aircraft flight and navigation. Sit
back and follow the maps while
"Jack" the autopilot and "Roger"
the Air Traffic Controller (spoken
ATC messages with optional
SoundBlaster card) fly and guide
the aircraft from takeoff to
touchdown.
ATP contains visual scenery, over
350 airports and the radio naviga-
tion aids you need to fly jet routes
between all major U.S. cities. Fly
predeflned flight assignments or
select your own departure jrod^
destination airports. ATP
provides inflight Air Traffic
Control guidance and a postflight
performance evaluation.

For Windows
users, DOS 6 is an
upgrade that's
definitely worth
considering.
DO WINDOWS
USERS NEED
DOS 6?
If you live on a desert island,
you may not have tieard
about DOS 6. The rest of us,
tfiougti, hiave been hearing
about it a lot. And everyone's
trying to figure out tfie same
thing: Is it wortfi tfie $50 up-
grade? The ones wondering
the loudest are probably Win-
dows users. Many of us, after
all, don't have all that much to
do with DOS. So is DOS 6
worth the upgrade if you run
Windows? In a word, yes, and
in this column, I'll tell you why.
First, there are several Win-
dows programs included with
DOS 6: fvlicrosoft Undelete, f^i-
crosoft Backup, Microsoft An-
tivirus, and a Windows-hosted
compression information pro-
gram that works with Dou-
bleSpace.
The Undelete and Antivirus
programs are from Central
Point Software, and they strong-
ly resemble the programs of
the same name in PC Tools De-
luxe. The Backup program is
a special version of Syman-
tec's Norton Backup. These
are all first-class tools that any
Windows owner will be happy
with. And to its credit, the DOS
6 installation program automat-
ically installs a Microsoft Tools
group in Program Manager, a
Tools menu on File Manager,
and, if you're using Windows
for Workgroups, four new but-
tons on the File Manager's
toolbar.
Of these utilities, the Un-
delete program is especially
useful. It offers an easy way to
recover deleted files, and it
can be configured for three lev-
els of delete protection. With
Standard, a file can be recov-
ered if it hasn't been overwrit-
ten. With Delete Tracker, Un-
delete stores some informa-
tion about the state of each file
to make successful undeleting
more likely. And with Delete
Sentry, deleted files are actu-
ally spirited to a hidden subdi-
rectory and held there as long
as disk space permits. With De-
lete Sentry, files can always
be undeleted in perfect condi-
tion as long as you don't wait
too awfully iong.
The Undelete command in-
stalled in File Manager is very
helpful, too. The Installation pro-
gram puts this command on
the File menu, and, if you're us-
ing the Windows for
Workgroups File Manager, it in-
stalls an Undelete button on
the toolbar. When you access
Undelete from File Manager,
Undelete opens in the directo-
ry selected in File Manager.
It's much faster and easier to
select a directory in File Ivtan-
ager than to use Undelete's
Change Drive and Directory di-
alog box.
These Windows programs
are obviously useful to a Win-
dows user, but beyond them
there are several other signifi-
cant enhancements in this
DOS.
First, there's MemMaker. If
you run DOS programs from
Windows, this can be a god-
send. MemMaker optimizes
the way your computer uses
UMBs (Upper Memory
Blocks). On my PC, I'm run-
ning Stacker, DOS network driv-
ers, multimedia drivers, plus
the usual stuff like
SMARTDrive, Share, Mouse,
and Doskey. Before running
MemMaker, I had less than
500K of conventional memory
free in a DOS session, and
some DOS programs just
wouldn't run. After running
MemMai<er, I have about
570K of memory for DOS pro-
grams, and everything runs
fine. If you need more DOS
memory, MemMaker alone
may be worth the upgrade.
The next DOS 6 enhance-
ment that may be useful to Win-
dows users is Interlnk. If you
share information between
computers, Interlnk is an easy
way to move flies. With In-
terlnk, you have a client ma-
chine and a server machine.
On the client, you run an In-
terlnk device driver. On the
server, you run an Interlnk ex-
ecutable. When both pro-
grams have been run and
your computers are connect-
ed with either a serial or paral-
lel cable, the server's drives ap-
pear as virtual drives in both
DOS and Windows.
If you run Windows File Man-
ager on the client, you'll see
the server's drive icons on File
Manager's drive bar. You can
treat these drives just like your
machine's native drives. You
can display a directory tree
and file window for them, you
can copy files to and from
these drives, you can tile and
arrange the drive windows
mixed and matched with your
native drive's windows, and
you can run programs from
them.
The first time I ran Interlnk
between my desktop and lap-
top, I copied a directory and
all its subdirectories from the
client to the server by drag-
ging and dropping. This is the
easiest way I've seen to trans-
fer files between machines.
The last reason for Windows
users to upgrade to DOS 6 is
DoubleSpace, which can near-
ly double the size of your hard
disk. We all know fiow Win-
dows programs gobble up
disk real estate, and we can all
use the extra space. Dou-
bleSpace seems like a bless-
ing for Windows users, but no
other part of DOS 6 has
caused as much controversy.
Next issue, I'll talk about how to
install DoubleSpace, how to
use it, how it fares against Stack-
er, and some DoubleSpace
add-ons. If you want to go
ahead and try DoubleSpace,
please see my "DOS 6 First-
Aid Kit" in this issue for some
safety tips, D

Dazzle yourself witli

Screen Saver fieaven
Two readers sent in graphical
screen savers that were writ-
ten in QBASIC. Altiiough mon-
itor manufacturers insist tliat
llieir monitors won't be dam-
aged it left on for extended pe-
riods of lime, most people
don't like to take chances. Be-
sides, screen savers add an
appealing, interesting look to
w/hat might be a boring
screen with a command line
prompt. If you have DOS 5.0
or higher, you should have
QBASIC in your DOS directo-
ry. If it's missing, try reinstall-
ing DOS 5.0.
You can run any one of
these as an independent pro-
gram. I'd suggest putting
them all in a subdirectory
where you can keep track of
them, I put mine in a directo-
ry within my DOS directory
called SAVERS, All of my ref-
erences will assume a path to
the BASIC source code of
\DGS\SAVERS,
With QBASIC in your path
and the code in a central loca-
tion, you can type qbasic/run
\clos\savers\saver1 .has from
anywhere on your drive, and
the first screen saver will run.
You could also put this com-
mand in a batch file to save
typing.

With a little bit of effort and
some programming savvy,
you could turn these stand-
alone programs into some-
thing more. I wrote two small
utilities and a batch file that
use these screen savers.
The first utility waits a spec-
ified number of minutes. If
there's a keypress, it returns
with an errorlevel of 1. If the
time has elapsed, it returns
an errorlevel of 0, and you
can execute one of the
screen savers. It's called Wait-
time, and to use it, you just
type waittime followed by the
number of minutes you want
to wait.
The second utility returns a
random number as an error
code. You must specify a max-
imum value.. If you want it to re-
turn values from 0-14, you'd
type getrand 14.

If you run Checksum (July

Bradley M. Small (of Greens-
boro, North Carolina) points
out that if you change the last
two lines of Waittime, the pro-
gram will return the ASCII val-
ue of the key pressed as an
errorlevel.
If you are interested in cre-

How important
is it to
l(eep up with t)te
versions?
UPGRADE UPDATE
Have you upgraded to DOS 6
yet? Do you have the latest
and greatest version of your
word-processing program?
How about the newest install-
ment of your checkbook man-
ager, the one with charts and
graphs?
My mailbox — and I'll bet
yours, too — is often chock-full
of upgrade notices for the soft-
ware I own, and for some pro-
grams I don't own. All this mail
has me wondering how impor-
tant it is to keep up with the ver-
sions, software's version of sub-
urbia's keeping up with the
Joneses.
The answer is not a simple
one: It depends on how you
use your computer and fiow
you work.
For starters, let's take a
look at DOS 6. This is an inter-
esting, but not a revolutionary,
upgrade. In my case, it adds
nothing to nny system that is
not being accomplished by
some other commercial or
shareware program.
Do I need DOS 6? No.
Do I have DOS 6? You bet.
After all, this is a DOS column.
Its author ought to be in touch
with the latest DOS product
whether he needs it or not.
Upgrade Rule #1: If your
livelihood depends on the soft-
ware, upgrade.
Another issue to consider is
support. Do you, or those who
work for you, need help using
your software? Do you rely on
the software manufacturer's
support staff to help solve tech-
nical problems as well as to
give you guidance when you
don't feel like reading the man-
ual? If so, it's probably a good
idea to stay current for that
product; as each day passes,
the support staff will become
less and less familiar with the
foibles of past versions,
Upgrade Rule #2: Stay cur-
rent if you want handholding.
When deciding whether to
upgrade, you also must consid-
er whether you're a loner or
you share your work with oth-
ers. In the desktop publishing
business, for example, publica-
tion files often are worked on
by two or three people. Then
the files are handed over to a
service bureau for output. In a
case like this, it makes sense
to make sure everyone is up-
graded to the same software
level.
Upgrade Rule #3: Stay com-
patible with associates, ven-
dors, and suppliers.
Many software companies
seem to have embraced the
idea of annual upgrades. I'm
willing to bet that I'll see an up-
grade notice for my check-
book/financial manager soft-
ware this October. The pro-
gram's been upgraded each
of the last three autumns; why
should 1993 be any different?
Looking back at my re-
cords, 1 see I've paid more for
upgrades than for the original
version of that program. But
that's OK: the upgrades I've
purchased have added impor-
tant functions, made the pro-
gram easier to use, and
saved me time. I'm happy
with what I've paid for.
I did bypass last year's invi-
tation to upgrade, however.
The improvements in that up-
grade centered on the pro-
gram's new abilities to create
charts and graphs pertaining
to my financial situation. I
didn't see how those multicol-
or graphics would make me
richer or better organized finan-
cially, so I skipped the up-
grade and saved a few
bucks — a clear plus for my fi-
nancial status.
Upgrade Rule #4: Don't be
swayed by the fancy bro-
chures; it's up to you to decide
whether new features are val-
uable to you.
Finally, be aware that com-
puter and software technology
is a rapidly advancing field.
No program invented today
will be worth much in five
years. If you're buying soft-
ware that's central to your busi-
ness, plan to make regular up-
grades to stay on the cutting
edge. If you're a hobbyist, it
probably won't hurt you to be
a generation or two behind.
Upgrade Rule #5: Software
upgrades are a cost of doing
business — budget for them.
Now that we've looked at
whether to upgrade the soft-
ware you have, what about up-
grading the software you don't
have? This phenomenon has
become known as the compet-
itive upgrade, and for software
addicts, it's one of the best
deals around.
Let's say you own Brand X
word-processing program,
which normally lists for S495.
The maker of Brand Y word
processor wants you to con-
vert to his program, so he of-
fers you a competitive up-
grade for the price of $99.
What a deal! You get a brand-
new S495 program for $99!
If you like to acquire new
software, keep your eyes
open for the competitive up-
grade deals, and when the pro-
gram you're yearning for goes
on sale, snap it up.
But competitive upgrades
are a little unfair, and that may
contribute to their undoing.
Let's say you don't own a word-
processing program. How
does it make you feel to pay
full price, when everyone
around you buys a copy for 80
percent off?
1 find It hard to buy under
those conditions. I'll stay on
the sideline until the price
comes down for everybody.
Software companies are dis-
covering that lower software
prices translate into increased
sales. Perhaps before long,
the competitive upgrade pric-
es will become the suggested
retail prices.
Then the manufacturers will
have thousands of new poten-
tial upgrade customers. O

The only
ANSI-standard
BASIC
implementation
trom the guys
who invented BASIC
BASICALLY, A TRUE
BARGAIN
Continuing a BASIC hot
streak (last month, we cov-
ered the estimable PowerBA-
SIC), we turn to an amazing
bargain: The True BASIC Sam-
pler Edition, a $15 version of
the only ANSI-standard BASIC
implementation from the guys
who invented BASIC.
John Kemeny and Tom
Kurtz, two professors at Dart-
mouth, literally created BASIC
from scratch in 1964. They
wanted a friendlier introduc-
tion to computers than FOR-
TRAN, then the state of the art.
What is not so well known is
that they upgraded their BA-
SIC with astonishing speed,
creating interactive versions
that acted very much like
QuickBASIC did 20 years lat-
er. They gave the language a
host of features yet to be
matched in most other BA-
SICS, such as matrix manipu-
lation, advanced graphics, lo-
cal variables, and required
variable declarations, Kemeny
and Kurtz were understandably
embarrassed when simplified
imitations of the very earliest ver-
sion of their language were
cloned on every machine from
toy microcomputers to main-
frames and their beloved crea-
tion was then nearly throttled to
death by programming cogno-
scenti who judged it thirdhand
and pronounced the impostor
versions dead on arrival.
It is also relatively uncom-
mon knowledge that there is
an ANSI standard for BASIC,
ratified several years ago, and
True BASIC conforms to that
standard (QuickBASIC, GW-
BASIC. and the like don't even
come close). The obvious ques-
tion is, of course, so what?
QuickBASIC and QBASIC are
the de facto standards, run-
ning on millions of desktops,
as opposed to perhaps tens
or hundreds of thousands us-
ing True BASIC. It would not
be difficult to stop the argu-
ment there.
But an ANSI-standard BA-
SIC has the tantalizing poten-
tial of allowing, say, PCs, Macin-
toshes, Amigas, and Sun work-
stations to run the exact same
source code. Kemeny and
Kurtz finally wised up and
formed their own company,
one that now carries — sit
down; you'll be shocked
when you hear this — versions
of True BASIC that run identi-
cally on PCs, Macs. Amigas,
and Sun workstations. True BA-
SIC (it's the name of the com-
pany, too. and it's located at
12 Commerce Avenue, West
Lebanon, New Hampshire
03784: 800-872-2742, 603-
298-7015 [fax]) also carries a
host of True BASIC source li-
braries for math, scientific,
engineering, and some gener-
al-purpose use.
What's most exciting to me
is that you can experience
True BASIC yourself if you
own a PC compatible (or if you
slipped and accidentally
bought a Mac) for only
$14,95. This is easily the best
demo package I've ever
seen; it gives you a full version
of the language, the ability to
create files up to 150 lines
long, and a 208-page paper-
back book by the masters
themselves showing you BA-
SIC from the ground up, I got
both the Mac and the PC ver-
sions, and sure enough, the
same source runs identically
on the two machines.
True BASIC is a very differ-
ent animal from the other BA-
SICS. Like QuickBASIC and
QBASIC. it compiles pro-
grams in the background as
you type, so you get the
speed of a compiler with the
convenience of an interpreter.
The environment isn't nearly
as comfortable as QBASIC, al-
though it's similar in concept:
menus, an immediate window,
and so forth. The problem is
that it's clunky. You bring up
a menu by pressing Alt-1 for
the leftmost menu. Alt-2 for the
one next to it. and so on. The
help system, while user-exten-
sible, is phmitive and requires
that you press Ctrl-Break to
leave a help screen. F1 isn't
the help key, F10 isn't the
menu key, and it can't find
help files when run outside the
directory It was installed In.
True BASIC is very strong in
the math and string-handling
departments, TRUNCATE trun-
cates a number to the speci-
fied decimal places: MIN and
MAX return the minimum and
maximum of two numbers; pi
is built in; there's support for
natural, common (base 10),
and base 2 logarithms; and
more. There are whole groups
of string functions not found in
other BASICS. LTRIM, RTRIM,
and TRIM removing leading
and trailing blanks; CPOS
finds the first occurrence of a
character in a string; CPOSR
does the same but from the
end; NCPOS finds the first oc-
currence of a character not
found in a string; and
NCPOSR does the same but
from the end. There's a whole
array (sorry) of matrix-han-
dling statements and func-
tions, and the graphics subsys-
tem is far better thought out
than those built into other BA-
SICS.
The sample edition is a roar-
ing success, and my main crit-
icism is a political one. The
manual never mentions the Mi-
crosoft; BASIC variants, prob-
ably on the theory that there's
no reason to aid the competi-
tion. That doesn't make sense
to me. I'd much rather the
book contain a 10- or 12-
page comparative analysis
and conversion guide so that
interested parties could con-
vert their Microsoft BASIC
code over to True BASIC. This
would only increase its mar-
ket, a move both True BASIC
and we users deserve. G

DOS 6'S
MullJConfig lets you
combine several
AUTOEXECBAT and
CONFIG.SYS files.
DOS 6's MULTI-
CONFIG, PART 2
In the June issue, I started look-
ing Into MultiConflg, the new
DOS 6 feature that allows you
to unify your scattered CON-
FIG.SYS/AUTOEXEC.BAT
files. This month, we'll look fur-
ther into MultiConfig's many
capabilities.
If you have a color monitor,
you can customize the colors
of your MultiConflg menu with
the Menucolor command. It
looks like this: menucolor fore-
ground, [background].
Foreground and back-
ground are numbers represent-
ing the colors that the PC text
screen can display — there are
16 of them. Foreground is a
mandatory value, but back-
ground is optional. If you don't
specify a number, then you
just get the normal black
background.
I guess what troubles me
about this command is the
wasted time it causes. If you
remove all the combinations
where the foreground equals
the background, there are still
240 different foreground/back-
ground combinations. Experi-
ence has shown me that there
are a fair number of people
who won't rest until they've
seen them all.
So far, we've merged only
one of DOS's startup files. Now
that you've merged two differ-
ent CONFIG.SYS files into
one using MultiConflg, com-
plete with a startup menu,
defaults, timeouts, and even col-
ors, it's time to see what
MultiConflg does for your
AUTOEXECBAT, And the an-
swer is, "not much,"
There is, however, enough
in the way of tools to allow you
to link CONFIG.SYS configura-
tions to AUTOEXEC.BAT con-
figurations. Here's how.
Let's return to the two-con-
figuration approach we estab-
lished in June. Suppose there
are two AUTOEXEC. SATs,
one for the normal configura-
tion and another for the inter-
link configuration. The normal
AUTOEXEC.BAT might look
like this.
©ECHO OFF
PROMPT $P$G
PATH CXDOS
DOSKEY
The interlink AUTOEXEC.BAT
might look like this,
©ECHO OFF
PATH C:\DOS
INTERSVR
I want to explain this so both
batch veterans and begin-
ners can use this information,
so let nne first show the peo-
ple who are comfortable with
batch language programming
how to put these AUTOEX-
EC. BATs together into one
AUTOEXEC.BAT Then I'll pre-
sent a step-by-step formula
for combining batch files that
anyone who can use an edi-
tor can follow.
The key to being able to
combine two {or more) AU-
TOEXEC. BATs into a single
batch file and then extract
them as they were originally
is an environment variable
called CONFIG. It contains
the name of the configuration
that you selected — in our
example, that means either
normal or interlink. You
then use "IF . . . ==" com-
mands and GOTOs to control
which part of the AUTOEX-
EC.BAT file is executed.
Here's what it would look like
for our example AUTOEX-
EC.BAT situation,
©ECHO OFF
IF %CDnfig%=normal GOTO
normal
IF %config%==interlink GOTO
interlink
:normal
PROMPT SP$G
PATH C:\DOS
58 COMPUTE AUGUST 1993
DOSKEY
GOTO end
:interllnk
PATH C:\DQS
IMTERSVR
GOTO end
:end
Batch experts may look upon
my approach in the previous
example as being a trifle inef-
ficient, but it follows a nice,
simple formula that anyone
can use to quickly combine a
number of configurations into
a single AUTOEXEC.BAT
Let's see how to use that
formula to assemble different
AUTOEXEC. BATs into a sin-
gle file. If we have three
AUTOEXEC.BAT configura-
tions that are named c1,
c2, and c3, we could
build our AUTOEXEC.BAT
like this.
©ECHO OFF
IF %conlig%==c1 GOTO c1
IF %conlig%==cZ GOTO c2
IF %ctinlig7o=c3 GOTO c3
:c1
[put the g1 commands tiere]
GOTO end
:c2
[put the cZ commands here]
GOTO end
:c3
[put the c3 commands here]
GOTO end
:end
This skeleton of a batch file
is intended to underscore
how to build an AUTOEX-
EC.BAT that supports three
configurations. You can easi-
ly see how to extend it to
four, five, or any number of
configurations.
It may be obvious, but I'll
mention anyway that the lines
in brackets shouldn't be
typed literally; they're intend-
ed to be instructions to you,
not to be typed to the PC,
Perhaps even more gener-
ally, you can assemble a com-
bined AUTOEXEC.BAT using
this step-by-step method.
Step 1: The first line of
your combined AUTOEX-
EC.BAT stiould be an
©ECHO OFF.
Step 2: Examine your CON-
FIG-SYS's [menu] section
tfiat you assembled previous-
ly and write down the names
of all the configurations. Take
the name of the first configu-
ration and incorporate it into
an if statement that looks like
this: IF %config%==[name of
configuration] GOTO [name
of configuration].
You should replace [name
of configuration] with the
actual name of the first
configuration. Do that for
each configuration name.
For example, suppose you
find that your CONFIG.SYS
has a menu section that
looks like this.
[menu]
menuitem standard, Normal
stuff I use
menuitem maxniemory,Set up
to give maximum free
memory
menuitem wingcomm.Conflgura-
tion to run Wing Commander II
menudefault . . .
That means that you have
three configurations named
standard, maxmemory, and
wingcomm. (Notice that I
didn't include the normal and
interlink configurations. I
didn't want you to start think-
ing that they were mandato-
ry.) You'd prepare the first con-
figuration IF to look like this:
IF %config%==standard
GOTO standard,
Notice that the ==standard
is in lowercase. The case in
the IF statement must match
the case of the named config-
uration, or this just plain won't
work.
You'd then assemble the
other IF statements, one for
each of the two other config-
urations, and you'd have an
AUTOEXEC.BAT that looks
like this.
©ECHO OFF
IF %config%==standard GOTO
standard
IF %conflg%==maxmemory GOTO
maxmemory
IF %Eonlig%==wing(;amm GOTO
wingcomm
Step 3: Create a section of
the AUTOEXEC.BAT for each
of the configurations. Each
section should have two
lines. The first line is
the name of the configuration
preceded by a colon, and
the second line should
say GOTO end. The iast line
in the batch file should say
:end. [f you do that,
your AUTOEXECBAT will
look like this.
©ECHO OFF
IF %CDnfig7D==standard GOTO
standard
IF %contig%==maxmemory GOTO
maxmemory
IF %config%==wingcomm GOTO
wingcomm
iwingcomm
GOTO end
imaxmemory
GOTO end
istandard
GOTO end
:end
Step 4: For each section, in-
sert the AUTOEXEC.BAT for
that section between the label
with the colon at the begin-
ning of it and the GOTO end.
Save this file, and you're
done.
To put it all together, let's
suppose the AUTOEXEC.BAT
for the standard configuration
looks like this.
PROMPT SPSG
PATH C:\DOS
DOSKEY
PRINT Id
SIVIARTDRV
The configuration for maxmem-
ory looks like this.
PROIWPT $P$G
PATH C:\DOS
LH DOSKEY
And the configuration for wing-
comm looks like this.
CD\GAMES\WCZ
WC2
You'd insert these files into
the AUTOEXEC.BAT that
you're building, and your final
AUTOEXEC.BAT would look
like this.
©ECHO OFF
IF %coniig%=standard GOTO
standard
IF %conflg%==maxmemory GOTO
maxmemory
IF %conflg%==wingcomm GOTO
wingcomm
:standard
PROMPT SPSG
PATH C:\DOS
DOSKEY
PRINTS
SMARTDRV
GOTO end
imaxmemory
PROMPT SP$G
PATH C:\DOS
LH DOSKEY
GOTO end
rwingcomm
CD\GAMES\WC2
WC2
GOTO end
:end

and painless way to integrate
your configurations under

The desktop pubiishtng revolution
has made the persoaot compoter the playground of the
forfer and the counterfeiter — or has III
^^ure, you're an honest person.
"v. Basically. But you've applied for a
f nice job. and they want a letter of
recommendation from, say, your col-
lege department head. But all they're
likely to get from that professor is a
damning letter describing what you
were caught doing while the lab
burned. In fact, you have a letter tike
that sitting in front of you now, written
on university letterhead and signed
by your professor.
Desperately, you cast about for a
solution to your dilemma — and note
that your computer has a color scan-
ner and a laser printer attached to it.
So you could just scan in the letter-
head and the signature, and write
your own letter.
Why not? Who would know?
Forging Ahead
Weicome to desktop forgery. It's a new
scam many observers expect to snow-
ball as technology makes documents
easier and easier to reproduce, per-
haps ending the concept of face value.
And perhaps also changing the way
some of our paperbound institutions
function.
Or perhaps not — because we still
have those first two questions;
Why not? Because it would be
wrong (to paraphrase Richard Nixon).
Who would know? The people who
catch you. Because you're very likely
to get caught.
For instance, the printout from your
laser printer could be traced back to
you — although it's difficult to make
such a trace, acknowledges fvlike
Noblett, chief of the Document
Analysis Research and Training Unit
at FBI headquarters in Washington,
DC. Fans of detective novels know all
about how the FBI collects print sam-
ples from typewriter brands and how
every manual typewriter has distinc-
tive wear patterns that can identify its
output. Of course, hardly anybody
uses such machines anymore, but the
rollers and paper grabbers of laser
printers do leave distinctive marks that
can at least give away what brand of
printer was used, Noblett notes. And
scratches on the toner drum (if there
are any) can be distinctive enough to
identify an individual machine.
So you resolve to get a new toner
cartridge just for this scam. But after
that, you run into a problem — the letter-
head you want to copy includes an
embossed silver logo. Your laser printer
can't emboss anything, and no metallic
(silver, gold, or bronze) toner is avail-
able for laser printers, even if your
scanner could pick up those reflective
colors. That's why you see more and
MOUNT JJ&ma COLLLGIL
DRAMA DEPAHTMENT
more letterheads printed with em-
bossed metallic backgrounds, explains
William Flynn, a document examiner
and president of Affiliated Forensic
Laboratories in Phoenix, Arizona.
Anyway, you ponder, you also have
to fake a letterhead envelope, and
that's even harder. Indeed, sources say
that beginners often give themselves
away by overlooking the need for a
convincing envelope. Or by leaving
their fingerprints all over it, even when
the document inside is surgically clean.
Ah, you think, but what if I fax the
letter? Everyone faxes everything
these days. All faxes are black-and-
white, so the ohginal color won't mat-
ter. And no envelope is needed.
So you whip out something con-
vincing and head down to the copy
shop to use the fax machine. There
are other people there, too, nervously
making photocopies of medical
records, buying snapshot film, finger-
ing check paper, and making furtive
glances at the color copier.
Are they up to something, too? you
wonder. No, they probably aren't. But
maybe it's just as well that you wonder.
Paper Hanging
Those people fingering the check
paper in the copy shop can give the
hives to someone like Susan Ivlorton.
senior forensic document examiner
with the U.S. Postal Service in San
Francisco. While laser printers were
once considered unsuitable for punt-
ing checks, today even large payroll
firms use them, leaving bank tellers
accustomed to the sight of laser-pro-
duced checks, she mourns.
The result is that she has seen
gangs traveling the country packing
computers, scanners, and laser pnnt-
ers. Arriving in a town, their first move
is to rob a mailbox to acquire some
checks that were mailed to, say, the
local utility company. They will copy
the account and routing code off
some citizen's check and decide
what branch bank that person proba-
bly uses. Then they forge a large cor-
porate or government check to that
person, using information from other
checks they found in the nnail.
Packing a forged ID, a gang member
will then go to a branch across town
where presumably nobody knows the
citizen and deposit part of that forged
check. The check may be for $5,000,
of which the forger takes $2,000 as
cash, smiles, and leaves.
The bank may admit it's been
scammed, or it may seek to blame the
innocent citizen. "Some banks are
nice and cooperative, and some can
hassle you for years," Morton notes.

One check-forging gang was
chased across Texas for about six
months in the late 1980s, recalls
Robert Ansley, corporate security
manager for Dell Computer in Austin,
Texas, then with the Austin police
department. Armed with a stolen
Macintosh and an ID maker stolen
from a highway patrol substation, they
passed more than $100,000 in bogus
checks in Austin alone. But instead of
hiring street people to go into the
bank, as other gangs have done, they
used the same woman over and over,
and her description was sent to every
check-cashing outlet in the city. A
teller spotter her, she fled — and it
turns out the gang had overlooked the
detail of forging a license plate for
their getaway pickup truck.
Sources say other gangs have
used laser printers to forge security
ID badges to get into office buildings
and steal the computers, nodding to
the friendly security guard at the front
desk while trudging out with their
arms full, But they usually find that
fencing computers is harder than
stealing them, and get caught.
Knowing this, perhaps you've
decided that forging is not the career
for you. And anyway, you're just one
faxed letter away from a good job. So
you fax your forged letter from the
copy shop. Your prospective employer
gets it. And sees from the ID line that
fax machines insert at the top of each
page that the letter came from the
copy shop down the street, instead of
that university three states away.
The fax, and your job, go straight
into the trash can.
Copycats
You're not alone in getting caught.
Think back to the crowd at the copy
shop. That medical professional was
creating a new page for a patient file
with some dates changed to make
himself look like a genius instead of a
quack. But at the malpractice trial it
comes out that the page in question
has one set of staple holes and all the
surrounding pages have seven. The
person buying the snapshot film was
trying to back up a burglary insurance
claim, but the insurance investigator
checks the production code on the
back of the film and finds it was made
some weeks after the photographed
jewelry was supposedly stolen. The
ones fingering the check paper get
caught as described. As for that furtive
guy at the color copier — he's doomed.
So, to return to our earlier question,
does all this new technology mean
our paperbound civilization is in dan-
ger of coming apart at the seams?
Apparently not, "We have not seen
an increase in the amount of document
fraud per se," says Nobiett. "We have
seen more and more computer-gener-
ated documents, but the total amount
[of document fraud] is about the same.
Computers have also made things easi-
er for counterfeiters, but we don't see
any more counterfeiters than before."
So perhaps people have remained
basically honest— although a few safe-
guards may be in order. "We have
been urging corporations to move for-
ward with EDI [paperless invoicing,
ordering, and so forth, using Electronic
Data Interchange] for more and more
of their business transactions and
avoid paper, since it will become so
vulnerable," says Donn Parker, com-
puter crime expert with SRI Inter-
national in Menio Park, California.
Read This or Go to Jail
Yes, modern color copiers make
reproductions of paper money so
convincing that they can often readily
be passed, notes Gayle Moore, spe-
cial agent with the public affairs office
of the U.S. Secret Service in
Washington, DC,
And making such copies can get

you sent to prison for 15 years, fined
S5,000, or both, siie adds. And you're
likely to get caught because, while the
reproductions may look good, they
don't feel anything like paper
money — they are far slicker.
Meanwhile, new anticopying mea-
sures are being added to U.S. curren-
cy. Microprinting is being added
around the outside of the portraits,
which copiers will pick up only as
fuzzy lines— which is all it looks like
except under high magnification. And
plastic strips are being added inside
the paper itself — a copier won't repro-
duce them, but they will appear when
you hold a genuine bill up to the light
Meanwhile, Canon USA is said to
be adding anticounterfeiting technoio-
gy to its color copiers. A Canon
spokesman declined to discuss the
matter, but other sources say the
technology can sense the graphical
patterns of U.S. currency in whatever
it scans. If currency is detected, the
unit wili spit out a black page.
But serious counterfeiters are likely
to eschew color copiers anyway, pre-
ferring traditional methods, Moore
notes. While a $47,000 color copier
might give you seven copies a minute,
you can churn out millions of bogus
dollars a day with an offset press. So
color copiers are mostly used for low-
volume opportunistic counterfeiting,
she explains. In 1991, the Secret
Service busted 66 traditional counter-
feiting operations, while seizing 52
office machines that had been used
for counterfeiting. But whichever
method is used, there is usually some
paper trail connecting the perpetrator
to the machinery, she notes.
Meanwhile, truly sophisticated
counterfeiters are often too smart to
waste their time producing money,
preferring negotiable instruments iike
stocks and bonds. Desktop forgery
hasn't been much of a factor in this
field, says Jack R. Calvert, director of
the National Forensic Laboratory of the
Criminal Investigation Division of the
Internal Revenue Service in Chicago,
since copiers still don't have the reso-
lution to defeat the safeguards of the
safety paper such bonds are printed
on. Safety paper can have panta-
grams (continuous background pat-
terns) that appear only when a photo-
copy is made, ink that appears only
under special lights, or watermarks no
copier can duplicate.
"Things are not falling apart yet,
but we are running at full tilt to coun-
teract anything that might come out in
the near future." he says.
Meanwhile, perhaps you should
consider joining the other side. There
are estimated to be fewer than 600
qualified document examiners in the
U.S. and Canada, and the industry is
looking for new blood. If you're inter-
ested, George Pearl of Atlanta, presi-
dent of the Association of Forensic
Document Examiners, urges you to
contact AFDE's membership director,
Vickie Willard, at 526 Superior
Avenue, Suite 740, Cleveland, Ohio
44114, or (216) 574-2204. It takes
about two years to learn the trade.
Don't Do the Crime
Don't do the crime. If you can't do the
time, as the theme song from "Baret-
ta" used to say, It's so easy to break
certain laws with a computer that peo-
ple sometimes forget they're engaging
in criminal acts. You could make
enough copies of WordPerfect in an
afternoon to supply everyone on the
block, but you would be breaking fed-
eral laws by doing so — and more and
more pirates are being caught and
prosecuted. Scanning in a dollar bill
takes seconds, and printing out hun-
dreds of them takes only a few min-
utes. But when you figure years behind
bars into the equation, you just might
not have time to take the risk, j

With 45 fonts, 600 dpi, supersonic
speed, and a great price, tliis printer leaves
you with no reason not to buy it.
William Harrei
LASERJET 4
It's no wonder that Hewlett-
Packard's LaserJet printers
are so popular. Hewlett-Pack-
ard consistently offers great
printers at incredible prices.
The LaserJet 4 is no excep-
tion, In fact, it's the best Las-
erJet ever, and it's the best val-
ue Hewlett-Packard has
offered so far. With a suggest-
ed retail price of $1,759 (if
you look around, you can find
one for around $1,400). the
LaserJet 4 weighs in at $200
dollars cheaper than the Las-
erJet III. For the price, the Las-
erJet 4 gives you four times
the resolution, 37 more fonts,
much improved print quality,
and over twice the speed.
f\/lany computer pundits
have hailed 1993 as the year
of the 600-dpi (dots per inch)
printer. Why 600 dpi? While
this seems like only twice the
resolution of standard 300-dpi
printers, it's actually four
times higher. Smaller, tighter
dots mean crisper, cleaner
text. That means type in
small point sizes (such as,
say, 12 points or lower) main-
tains its fine lines and stroke
weights, and large text re-
mains black and has smooth,
sharp edges.
But where you'll really no-
tice the difference with a 600
dpi phnter is in printing gray-
scale and graphical images.
Since laser printers simulate
shades of gray by alternating
black dots with noncovered
white areas, 600 dpi offers a
significant improvement over
300 dpi. When you use a 600-
dpi machine, what you wind
up with is about four times the
number of simulated shades
of gray that you can get with
a 300-dpi machine.
Need more fonts? The Las-
erJet 4 is more than obliging.
It comes v/ith 35 scalable
Intellifont outlines, including
Garamond, CG Omega, and
Albertus; plus it has a
TrueType font rasterizer and
the ten TrueType fonts in Win-
dows — families of Arial and
Times New Roman, as well as
Symbol and WingDIngs.
And, if you have a LaserJet
4, you can also download any
Intellifont or TrueType outline
to the printer. PostScript
Type 1 fonts are supported
as well, with a $499 Post-
Script Level II upgrade. (Post-
Script is the standard lan-
guage used by graphic art-
ists and desktop publishers,
They use PostSchpt printers
to proof their documents be-
fore taking them to service bu-
reaus for a final, high-resolu-
tion imagesetter output.)
You can, of course, use
Adobe Type fvlanager (ATM)
to utilize Type 1 font technol-
ogy on the LaserJet 4. ATM
costs only $99, but before
you buy it, make sure you
don't already have a copy. It
comes bundled with many
popular word-processing,
desktop publishing, and graph-
ics applications.
Just when you thought print-
ers couldn't get any faster,
Hewlett-Packard comes
through again. The compa-
ny's Printer Command Lan-
guage 5 (PCL 5), the lan-
guage used in LaserJet Ills
and 4s, is already faster than
most other languages — espe-
cially the popular PostScript.
But the addition of the
TrueType font rasterizer and
Windows TrueType fonts
means that you don't have to
wait for your computer to
download fonts. The LaserJet
4 comes with one of the fast-
est processors in the busi-
ness: Intel's 20-fvlHz 80960
RISC processor. It also has
increased data compression.
What all these new enhance-
ments mean to you is that the
LaserJet 4 is one fast printer —
perhaps the fastest eight-
ppm (pages per minute) print-
er available on the market to-
day. Another terrific speed
eniiancement you'll really ap-
preciate is Hewlett-Packard's
new Bi-Tronic bidirectional
port. The Bi-Tronic can han-
dle data transfers at up to
156 kilobytes per second,
which is a much faster rate
than that offered by standard
parallel ports. Depending on
the speed of the computer it's
connected to, the Bi-Tronic
traditionally sends data to the
printer at between 50 and
66 COMPUTE AUGUST 1993
150 kilobytes per second. So
the only thing that will hold
back the LaserJet 4 is the
speed of your computer.
The bidirectional parallel
port also talks back to your
computer, in a simitar manner
that a serial port talks with a
Mac. Wouldn't it be great if
you could get a nnessage on
your computer screen that
tells you when your printer is
out of paper or that notifies
you of a paper jam, instead of
your having to walk down the
hall to see what's holding
things up? The LaserJet 4 is
capable of this kind of two-
way communication with your
con^puter. However, as of yet
there is no software interface
support for either DOS or Win-
dows. In order for your com-
puter to receive the printer's
messages, support must be
written into DOS applications,
Windows users, take heart,
fvlicrosoft is working on soft-
ware to activate the Bi-Tronic
interface under Windows. It
may be available by the time
you read this; check the Micro-
soft forum on CompuServe, or
look on the Microsoft BBS.
All these wonderful frills
aside, the question remains:
How does the LaserJet 4 ac-
tually print? I tested speed
and output against a
Lexmark 4029 600-dpi print-
er. The Lexmark 4029 has a
software option — the 4029 Win-
dows Print Accelerator — that
uses TrueType fonts to turn in
record print times at 300 dpi.
In some of my field tests,
especially when I was print-
ing pages containing just
TrueType text, the LaserJet 4
was a hair faster than the
Lexmark 4029: however, the
LaserJet ran at about the
same speed as the 4029
when I was printing pages con-
taining graphics.
The print-quality tests — in
which I was comparing the
smoothness of type, mono-
tone graphics, and gray-
scale photographs of the print-
outs—revealed that Hewlett-
Packard's Resolution Enhance-
ment Technology (RET) is
slightly superior to the
Lexmark's Print Quality
Enhancement Technology
(POET).
On the LaserJet 4, smal
text (12 points and under)
prints just a little crisper and
large text (14 points and high-
er) looks a little smoother.
There is. however, a quite no-
ticeable difference in quality
when you use a nnagnifying
glass to compare the print
samples. The LaserJet 4
prints text much better.
Graphics and photographs
also come out cleaner and
with seemingly more shades
of gray when printed on the
LaserJet 4. I always thought
that the Lexmark's halftone
quality couldn't be beat — un-
til I saw what came rolling out
of the LaserJet 4. It's quite im-
pressive!
Once again, Hewlett-Pack-
ard has done what it usually
does better than anybody
else in the printer market: It
has created a fine printer at a
fine price. As with the earlier
LaserJets, this one sets sever-
al new standards.
First, although 600-dpi print-
ing has been available for a
while now, it has never been
offered at such a reasonable
price. Usually, if Hewlett-Pack-
ard has it, everybody else
soon will. Second, last fall
Hewlett-Packard entered into
an agreement with Microsoft
to develop Windows-based
printing standards. The first re-
sults of this team effort are
the resident TrueType fonts in
the LaserJet 4 and the bidirec-
tional parallel port. Count on
the bidirectional port being
the next-generation computer-
printer interface, with several
other printers sporting it by
year's end.
With all this, there are few-
er and fewer reasons for busi-
ness users to shell out the
cost of PostScript. PCL 5 now
offers scalable-font technolo-
gy, higher resolution, better
handling of vector (draw-
type) graphics, on-board
TrueType fonts, and a low
price — all of which give the
LaserJet 4 a true advantage
over other 600-dpi printers.
Do you need 600 dpi?
Well, look at it this way: Con-
sidering all the other features
and the improved print
speed and quality of this print-
er, the higher resolution is
just a bonus. If you're in the
market for a new printer, un-
less you are a desktop publish-
er or graphics designer, you
can't beat this one. d

Rosalind B. Resnick
It you look before
you leap and
buy exactly the
computer you
need, you'll tind the
bargain mat's
waiting for you.
TO ERR IS HUMAN
With all the great deals on com-
puters these days, it seems as
if you can't go wrong in select-
ing a new computer. Surpris-
ingly, though, many people do
go wrong.
Here are ten common mis-
takes that computer buyers
make and some tips to help
you avoid them:
Not asking yourself why you
need the computer in the first
place. Before you can shop in-
telligently for a computer, you
have to decide what tasks you
want to use it for and what soft-
ware you'll be using. If you
plan to do mostly word proc-
essing, for exannple, you can
get by with a less powerful —
and less expensive — comput-
er than if you intend to do desk-
top publishing or run lots of
Windows applications.
Not doing your homework be-
forehand. While benchmarks
and test procedures vary from
reviewer to reviewer, product
reviews can be a valuable
guide to a computer's perform-
ance. Don't forget that
friends, colleagues, us-
er-group members, and even
bulletin boards can offer use-
ful suggestions as to which
computer to buy — and which
computer to steer clear of.
Buying too little random ac-
cess memory. As the adage
goes. You can never be too
rich or too thin — or have too
much RAM. Especially if
you're planning to use soft-
ware that runs under Win-
dows. You're going to need at
least 4MB of RAM; some ex-
perts suggest SMB. "Sixteen
would be even better," says
Jerry Siegel, a computer con-
sultant in Hollywood, Florida.
Even with RAM prices higher
than usual right now, it's one
of the least expensive up-
grades you can make.
Buying too small a hard
drive. Just a few years ago, a
40MB hard drive was consid-
ered quite roomy. But now
that Windows has burst onto
the scene, PCs with hard
drives as large as 250MB are
not uncommon. That's be-
cause some Windows pro-
grams, such as Word for Win-
dows 2.0, grab upwards of
10MB of hard disk space and
require lots of room to run.
Buying a microprocessor
(CPU) (hat can't be upgraded.
While the 386 computer you
buy today may be adequate
for now, chances are that be-
fore long you'll need a PC with
a 486 processor to run the new-
est software. By spending a lit-
tle more to buy a PC that's up-
gradable, you won't have to
junk the thing a year from now.
Spending big money to up-
grade your old PC. Now that
computer prices are down, it's
hard to justify the cost of out-
fitting your old computer with
a bigger hard drive or a color
monitor. "Throw away and buy
new," suggests Robbie Ro-
bertson, a consultant in Water-
loo, Iowa, "or better yet, sell
the old while there is still a mar-
ket for it, and buy new."
Buying the latest and great-
est system on the market.
While you shouldn't buy less
computing power than you
need, there's no reason to buy
more. State-of-the-art systems
often carry a premium price.
For example, a top-of-the-line
PC equipped with Intel's 66-
MHz 486DX2 chip sells for
about $3,000 these days,
while you can get a slightly
slower PC with a 50-MHz chip
for $1,000 less. If you're like
most users, the difference in
speed will be far less notice-
able than the dent in your
bank account.
Failing to arrange for good
technical support. Unless
you're handy with a screwdriv-
er and unafraid of tinkering
with your AUTOEXEC.BAT
file, you'il want to pick a PC ven-
dor that offers prompt, reliable
technical support. Some com-
panies offer on-site service, oth-
ers offer a toll-free hot line,
while still others let you sink or
swim on your own. It may also
make sense to invest in an
extended warranty.
Paying cash. If your credit
card offers a buyer protection
plan, it's a good idea to use
your card, rather than cash or
a check, to buy your PC. This
way, you're protected if the
computer you get turns out to
be a lemon or the company
you bought it from goes belly
up.
Grabbing a deal that seems
too good to be true. These
days, some PC vendors are
hawking 486-ohip systems for
rock-bottom prices of under
$1,000. But not all 486s are
alike, warns Ytsroel Goodman,
a consultant in Far Rockaway,
New York. "[A low price] does
not mean that [the company]
put together a balanced sys-
tem and then discovered to
their delight that they could
sell it for $995," Goodman
says. "It means that they pur-
chased the cheapest compo-
nents they could in order to as-
semble a $995 system."
If you look before you leap,
use your money wisely, and
match your purchase to your
purpose, you'll find the bar-
gain that's waiting for you. D

MULTIMEDIA PC
David English
There were a
lot of new
multimedia products
at this year's
Infermedia show.
MULTIMEDIA
MEGASHOW
It's billed as the world's largest
multimedia event, with over
10,000 attendees and 150 ex-
hibiting companies. Last year it
acquired the weighty title of
The Seventh Annual Confer-
ence & Exposition on Multime-
dia and CD-ROfvl. This year, it
was simply called /nfermedia.
On the conference side of
intermedia, attendees heard a
lot of talk about converging tech-
nologies (though one speaker
noted that "colliding cultures"
would be a more appropriate
way of putting it). Everyone, it
seems, is either anticipating or
dreading the coming merger of
computers, cable television,
broadcast television, publish-
ing, consumer electronics, tel-
ephones, movies, and the re-
cording industry. Not surprising-
ly, computer and software com-
panies are rushing to form alli-
ances with companies in other
fields, so as not to be left be-
hind. Microsoft, for example,
showed a computer-enhanced
television that lets you view re-
altime statistics and order stadi-
um tickets while watching a
baseball game.
fvleanwhile, back on the
show floor, you could almost
smell the optimism in the air as
companies displayed their lat-
est crop of multimedia prod-
ucts. Warner New Ivledia daz-
zled showgoers with Hell Cab,
a nightmarish ride with a New
York cab driver who is out to
capture your soul. Stunning 3-
D graphics and sound make
this Macintosh CD-ROM a
ride to remember. A PC ver-
sion should be cruising the
streets soon.
f\/licrosoft announced three
newCD-ROIvl titles, including fvli-
crosoft Dinosaurs, a sumptu-
ous look at everyone's favorite
former earth rulers. Dinosaurs
includes over 1000 high-quali-
ty illustrations and photo-
graphs, 200 background arti-
cles, plenty of ambient sounds
and growls, and even dinosaur
screen savers, fvlicrosoft
worked with The Dinosaur So-
ciety to verify the information
and included a section for us
old fogies which explains that
many of the dinosaur facts we
learned as kids are no longer
true. The other new Microsoft ti-
tles are Multimedia Mozart: The
Dissonant Quartet and Multime-
dia Stravinsky: The Rite of
Spring. LikeMultimedia Beethov-
en: The Ninth Symphony, each
contains a famous work of clas-
sical music and a wealth of
background information.
DeLorme showed the foliow-
up to its popular CD-ROM ap-
plications. Street Atlas USA
and MapExpert, It's called Glob-
al Explorer, and it contains
street maps for more than
120,000 places worldwide, as
well as detailed topographic
maps for the entire world.
Asymetrix introduced a power-
ful multimedia presentation pro-
gram called Compel, with exten-
sive video, animation, and
sound support. In a break from
its usual hardware products,
ATI demonstrated its new vid-
eo editor, MediaMerge. It lets
you edit video files, record and
edit audio, and add a variety of
transition effects.
Other new CD-ROM titles in-
clude Jazz; A Multimedia His-
tory from Compton's NewMe-
dia, which lets you hear as well
as read about the legends of
jazz, from Duke Ellington and
Louis Armstrong to Miles Davis
and Weather Report; Interac-
tive Venture's Mayo Clinic Fam-
ily Health Book, which includes
45 animations and 500 color
illustrations, in addition to 1300
pages of interactive text; The
Compleat Beatles from Comp-
ton's NewMedia, which in-
cludes the entire documentary
film, TTie Compleat Beatles, as
well as text from the book of the
same name; Voyager's A Hard
Day's Night (initially available on-
ly for the Mac), which includes
the entire Beatles movie, the
movie's script (which can auto-
matically scroll with the movie),
and a preview trailer; TestDrive
Software System, a new quar-
terly CD-ROM from TestDrive,
which lets you try out and op-
tionally purchase major PC ap-
plications; and the 1993 edition
of the New Grolier Multimedia
Encyclopedia, which includes
dynamic maps and audio-visu-
al essays.
Adult CD-ROMs drew a lot
of attention at /ntermedia. Pop-
ular adult movies are now avail-
able on CD-ROM. Titles include
House of Sleeping Beauties,
from Pixar; Hidden Obses-
sions, from Romulus Entertain-
ment; and Things Change; My
First Time, from PC CompoNet.
At a special session devoted to
the future of erotic multimedia.
Penthouse wowed the crowd
with its first CD-ROM title. Pent-
house Interactive. It lets you be-
come the photographer in a
Penthouse photo shoot,
On the hardware front, you
can now equip your PCMCIA-
equipped laptop or notebook
computer with a variety of mul-
timedia options, including a
sound card (MediaShare's Tem-
po), a video capture card (Me-
diaShare's Focus), and a SCSI
adapter (Trantor's SlimSCSI).
NEC showed the first double-
speed portable CD-ROM
drive, the NEC MultiSpin 38 Port-
able CD-ROM Reader. Media
Vision displayed its new Pro Au-
dio Studio 16 package, which
includes an improved 16-bit
sound card, voice recognition
software, and a small micro-
phone. Creative Labs privately
showed me its own voice rec-
ognition software, which will be
available soon for its sound
cards, Finally Gold Disk dem-
onstrated VideoDirector, which
lets you use your computer
to control both your home
VCR and camcorder, allowing
you to quickly and easily
edit your videotapes. O

BY THE BOOKS
Each month, we receive doz-
ens of books for review. For
some reason, most of them
come addressed to me. Since
this is a column about publish-
ing, I thought I might take a mo-
ment to talk about the books
received as a group and to sin-
gle some out for attention.
Generally, computer books
are here-today-gone-tomor-
row books, temporally a step
above periodicals: a slightly
longer pause for paper be-
tween the forest and the recy-
cling bin. Not even used-book
dealers are interested in old
computer books. On the other
hand, during their brief life-
times, computer books are in-
valuable. They need to be rug-
gedly made, easy to read, full
of reference material, and
well indexed. The rigor of rap-
idly creating good books from
scratch that have a 6- to 18-
month shelf life has been the
ruin of more than one publish-
er (and has caused more than
one author to tear his or her
hair out).
Random House, like a lot of
major publishers, is a relative
newcomer to computer-book
publishing. Its books are mark-
edly more attractive than the
general run of the mill. If you
think you know what a comput-
er book looks like, you should
take a look at Random House
Electronic Publishing's books.
They use ample, but not exces-
sive, color, and the covers are
as attractive as those of any
trade paperback. Look for Rob-
in Raskin and Carol Ellison's
Parents, Kids, & Computers
(ISBN 0-679-73910-6, Ran-
dom House Electronic Publish-
ing, $20) if you want to see
what can be done with comput-
er books.
We receive many books on
fractals. I've probably seen no
fewer than a dozen in recent
months. These books general-
ly have the look of a good art
book, full of beautiful full-color
illustrations. Symmetry in Cha-
os: A Search for Pattern in
Mathematics, Art, and Nature
by Michael Field and Martin
Golubitsky (ISBN 0-19-853689-
5. Oxford University Press,
$35) is a tittle more than the
standard fractal book, in that
it explains in layman's terms
what is meant by symmetry
and chaos. !t goes into the
mathematics behind the frac-
tal designs and even provides
a collection of BASIC fractal
programs. Having published
books containing programs
(and macros) myself, I can for-
give the fact that there are
some typos in the programs.
Be forewarned: tJse a little com-
mon sense when typing in the
programs. You'll find some er-
rors. I don't think there is a prac-
tical way to eliminate them
from program listings pub-
lished in books.
Computer art books come
and go, but some have lasting
and universal interest. The
Computer Artist's Handbool<
by Lillian F. Schwartz (with Lau-
rens R. Schwartz; ISBN 0-393-
02795-3, W. W. Norton. $55)
tells you much more than how
to draw a circle in a paint pro-
gram. Lillian Schwartz is one
of the true pioneers of comput-
er art. She started creating art
with computers before comput-
ers were seen widely as a medi-
um for art. back when the ini-
tial stabs at computer graph-
ics were being made in the in-
ner sanctums of IBM and
AT & T. She talks about how
she created many computer
masterpieces. Along the way,
she drops hints for creating
images and illusions with the
computer, as well as describ-
ing the circumstances of
some of her great discoveries.
You may recall that a few
years ago an artist serendipi-
tously discovered that the
Mona Lisa was actually a self-
portrait of Leonardo da Vinci.
Schwartz was the discoverer
of that secret, and the story of
her discovery, complete with
sketches and computer en-
hancements of the painting,
an x-ray of the Mona Lisa, and
the original cartoon for the
Mona Lisa are provided. In ad-
dition to teaching a great deal
about the computer as an art-
ist's tool, Schwartz goes a
long way toward showing the
kind of innovative thinking an
artist must go through in order
to create original art. Virtually
every page contains full-color
computer graphics.
Don't forget to write to me to
let me know what you're up to
in the publishing world. Re-
member that I want to hear
about your projects and your
interests — and that I'm solicit-

DISCOVERY CHOICE
Land a 747 or a pterodactyl next to Big Ben —
anyttilng's possible when you're the director of this film
production and flight simulator package.
David Sears
STUNT ISLAND
Back in the early
days of filmmaking,
daring young aviators
often ended a day of
breatfitaking aerobatics
witfi grievous injuries. Dis-
ney Software's Stunt Is-
land — equal parts flight sim-
ulator, production studio,
and Hollywood magic — man-
ages to extract the danger
and intensify the fun. Sudden-
ly those of us with the urge to
barnstorm can prove our met-
tle for some virtual dollars and
even make some movies.
More important, however, we
can now go behind the
scenes and play the roles of di-
rector, set designer, property
manager, and stunt man.
Wearing all those hats proves
an educational experience,
and as an introduction to Hol-
lywood-style filmmaking, it's a
bargain that film school tuition
can't hope to beat.
Somewhere at sea, protect-
ed from the pesky mainland
safety regulations. Stunt Is-
land waits, the site of count-
less chase sequences, air-
borne rescues, dogfights,
and fiery crashes. The studio
anticipates certain dire circum-
stances and even provides
hospital facilities to patch up
stunt fliers, but fly straight. If
you foul up too often, you'll
flunk out of the competition.
Besides just flying around
the island scouting locations
for stunts, flying in the Stunt Pi-
lot of the Year competition is
probably the best way to ac-
quaint yourself with the envi-
rons. Each stunt in the compe-
tition is controlled by a script
similar to the ones used to
film entire movies. You'll have
a limited number of takes to
accomplish the stunt, but
each failed attempt costs you
and the studio money. Be-
sides, you should perform dan-
gerous stunts as few times as
possible.
In the competition, you'll
shoot down a World War II Ze-
ro, snag a balloon gondola us-
ing a wingtip, pilot a hang glid-
er into a medieval castle, land
in a burger stand parking lot,
egg-bomb the police from the
cockpit of an angry duck, and
much more. Through the com-
petition, you'll encounter a
few of the many planes that
stock the prop department's
hangars— everything from the
Boeing 747 to the SR-71A
Blackbird, the Sopwith Camel
to the pterodactyl. Each of
these aircraft handles much
as you would expect it to,
though to allow for seat-of-the-
pants flying, the controls
seem distilled down to a bare
minimum.
The simulator itself is top-
notch, especially considering
the number of planes availa-
ble. Except for the organic
craft, each vehicle offers a de-
tailed cockpit view along with
74 COMPUTE AUGUST 1993
the traditional left, right, rear,
and spotter plane perspec-
tives — and what a view! On a
speedy 80486, you won't no-
tice any stick sluggishness
even with 100-percent detail
and dithehng options active.
These and other simulation
characteristics are controlled
from a pop-up panel accessi-
ble throughout the game.
The island itself is small
enough to cross in a Curtiss
June Bug without too much
monotony, but it's probably
the largest back lot Holly-
wood has ever seen. Practical-
ly any action sequence imag-
inable can be made here.
Stunt Island's educational
value doesn't lie in its nifty
flight simulator, though the
chance to fly the 45 available
planes is worth the purchase
price. Actually, Stunt Island
gives you the chance not on-
ly to fly stunts but to engineer
and script them yourself.
From the Set Design
screen, you can select any is-
land location as your site.
Once you have a site in
mind, stock your set! You
may place up to 40 props on
the set at one time, but only
thie first 8 v/ill act as cameras.
Of ttiese, slot 1 belongs to
ttie stunt plane, and slot 2 to
thie spotter plane. The rest of
ttie slots can hold any object
and be placed anywhere.
The cameras can take the
form of objects, visible or invis-
ible. Even the stunt craft and
the spotter plane can be-
come any object. From the
hundreds of props, you might
find the letter W makes an ex-
cellent and unique space-
craft — and why not? It's your
movie. Why not film an inva-
sion sequence as angry con-
sonants storm the earth?
Props range from historic land-
marks, such as Big Ben and
the Eiffel Tower, to the more
mundane, such as road
signs and boulders.
Positioning objects on the
set and imparting them with
motion characteristics such
as pitch, yaw, and roll takes
seconds using the pop-up con-
trol panels. If you can imag-
ine in 3-D, planning an interest-
ing set takes very little time; if
not, the superb 3-D modeler
puts everything onscreen for
you as you place it, from the
perspective you choose.
As mentioned, pilots com-
plete stunts according to par-
ameters set up by scripts. A
script consists of events that
you define using a set of intu-
itive pull-down menus within
the Set Design screen. For ex-
ample, you might want the pi-
lot to guide his Bristol Bulldog
between two trees to the left
of a road. From the menus
you can define the area be-
tween the two trees as a colli-
sion window. Then, whenever
the aircraft passes through
the window, an event has oc-
curred, and the program will
follow further Instructions you
give for that event. These in-
structions can check time lim-
its and aircraft speed,
change the shape of objects,
and trigger animation or
sound. This abbreviated list on-
ly hints at the potential hidden
under the Event option. Any
stunt you can imagine, you
can script here, and the proc-
ess is much less taxing than
writing even a simple pro-
gram in BASIC.
At the screening room, you
can view the dailies — so
called for their timeliness. If
you choose to record a free
flight instead of a stunt, you'll
see a pilot's perspective of
the flight. If, however, you fly
a stunt with scheduled cuts
from camera to camera and
choose Auto Editing, you'll
see the sequence unfold
much the way it was intend-
ed, complete with point-of-
view changes to props be-
sides the aircraft and, of
course, multiple shots of the
same stunt. You can position
the seven cameras with impu-
nity. After all, in the virtual
world of Stunt Island, both the
cameras and the film are
free, so you can use more
than the average film budget
could afford.
No studio can complete a
motion picture without this
postproduction essential: ed-
iting. Stunt Island gives you
the opportunity to try your
hand at a variety of tech-
niques, such as cutting on ac-
tion or using parallel action to
heighten tension— and it also
allows you to make some ter-
rible decisions and put togeth-
er a grade D film out of grade
A takes. Essentially the edit-
ing studio consists of eight vid-
eo recorders that, if you use
eight cameras when flying the
stunt, will hold up to eight sep-
arate roils of processed film.
These recorders can also
load stock footage from other
stunts, should you care to
open the vaults.
To edit footage, you just
mark the beginning and end
of the footage you'd like to
use in your film, using the log-
ically labeled onscreen but-
tons. Next, copy the footage
to the destination VCR. As
you switch from source deck
to source deck, fast-forward-
ing and rewinding, you soon

that Stunt Island's editing
room can teach neophyte film-
makers is that inspired editing
can sometimes salvage the
worst footage. For this to hap-
pen, editors must practice,
and a few good books on ed-
iting could prove invaluable.
Aim^d at film buffs and
flight-simulator fans, Stunt Is-
land seems too rare and too
powerful to simply be called a
game. With its straightforward
approach to moviemaking, it
could find a home in film
school editing classes, and it
just might inspire the next

tor summer release.
BfGGER GAMES,

MAKERS
Since Links 386 Pro started
the trend, everytining from
fligtit Sims to chess, from war
games to adventures is sport-
ing SVGA graphics. A few of
these include Buzz Aldrin's
Race into Space (simulation),
Empire Deluxe (strategy),
Rags to Riches (business sim-
ulation), Battlechess 4000
(chess). Car and Driver (rac-
ing simulation). Trump Castle
111 (gambling), AV-8B; Harrier
Assault (flight sim/war game),
SVGA Air Warrior (flight simu-
lation), the V for Victory series
(war games), and Gateway 11:
Homeworld (adventure).
Among the most recent re-
leases to show off SVGA graph-
ics is Gateway II: Homeworld,
Legend Entertainment's sec-
ond graphic adventure based
on Frederick Pohl's series of
science-fiction novels. Instead
of following the novels' plot
line, designers f^ike Verdue
and Glen Dahlgren relied on
the environment of the stories
to create a fresh episode in
the Gateway saga,
In this one you will travel the
stars in your quest for the
home planet of the Heechee,
a mysterious race of beings
on the far side of the universe.
If you enjoy puzzles based on
operating high-tech gadgetry
and devices, Gateway II is the
way to go. Many of the puz-
zles revolve around such ob-
jects, and some have their
own custom interfaces that
eliminate the need for typing
or even picking words from a
menu.
Gateway 11 features more of
everything that distinguished
the first Gateway — digitized
sounds, animation, and other
tered Lands. SSI may even
opt to do only a CD-ROM ver-
sion of M. That's because
many of the space-consuming
graphics would have to be
trimmed or cut completely
from a floppy-based version.
SSI was one of three major de-
velopers that downsized in
late spring. It lost 10 percent
of the staff but, according to
a spokesperson, it will still re-
lease 15 new titles this year as
scheduled.
Sierra and MicroProse also
reduced their staffs by 10 per-
special effects. The puzzles
will be just as difficult, so Leg-
end includes a free hint book
in the package.
Legend is currently adapt-
ing another classic series —
fantasy instead of science fic-
tion this time — as an adven-
ture. The Xanth novels of Piers
Anthony are the basis for Com-
panions of Xanth, due out
about this time. Legend also
publishes Steve fvleretzky's
Spellcasting quests, but the
original r\/ladman of Adventure
is up to something completely
different in his next game, It
will still be a comedy, though:
Meretzky's last shot at a "seri-
ous" adventure was A ivlind For-
ever Voyaging, which some
players dubbed A Game For-
ever Voyaging. Look for it any
day now.
But don't keep looking for
the PC version of M, SSI's sci-
ence-fiction adventure. It's
been postponed until next
year, along with the Super
NES version of Dark Sun: Shat-
cent. Sierra had some hits last
year, but reportedly took a beat-
ing due to the high startup
costs of The Sierra Network.
Though MicroProse reported
record revenues for the year,
unfortunately it also posted re-
cord expenses.
Science-fiction scenarios
continue to dominate the
games scheduled for release
as summer winds down and au-
tumn kicks in. Two more sci-
ence-fiction scenarios should
be docking at a spaceport
near you this month, each of-
fering a different slant on
spaceships and aliens.
Tsunami Ivledia's Protostar,
which is in the same vein as
Starflight, will be ten times big-
ger. Tsunami calls Protostar
". . . our most graphically stun-
ning game so far." That's say-
ing a iot, considering the lush
graphics of Ringworld.
Origin's Privateer, set in the
Wing Commander universe, is
also scheduled to show up
about this time. ts

Holographic images and fluid
gameplay help give this intense space-combat
simulator its high replay value.
Scott A. May
X-WING
It took some time and a lot of
effort, but the Force is finally
with us! X-Wing roars onto
computer screens as the fur-
ther realization of a dream
that began in 1977, with the in-
troduction of George Lucas's
Star Wars. Though initially in-
tended as a campy homage
to Hollywood's pulp adven-
ture serials, the film instead
carved a permanent niche in
popular culture. Ironically,
while the cinematic effects pi-
oneered by Industrial Light
and Magic have moved light-
years beyond Lucas's original
vision, today's powerful person-
al computers are only recent-
ly catching up. You could
say, then, that X-Wing has ac-
tually been 16 years in the
making. Spend some time
with this landmark simulation
and you'll agree — it was well
wortfi the wait,
LucasArts' creation invites
obvious comparisons to Ori-
gin's best-selling Wing Com-
mander series. Both are simi-
larly structured sci-fi epics,
enhanced by cinematic
segues, explosive sound ef-
fects, and in-your-face 3-D ac-
tion. The two products differ,
however, in direction and sub-
stance. Wing Commander
couid best be described as
an arcade-style space shoot-
'em-up, X-Wing, on the other
hand, strives to be the first au-
thentic space-combat simula-
tor. It succeeds brilliantly.
The game draws its great-
est inspiration from the origi-
nal Star Wars saga, charting
the formation of the Rebel Al-
liance against the evil Empire
and the construction of the
genocidal Death Star. A
lengthy animated introduction
sets the stage, with addition-
al background information pro-
vided in the richly illustrated
manual. Movie fans may be
disappointed that such main-
stays as Luke Skywalker and
Han Solo are nowhere to be
found. Instead, you become
the lead character, fulfilling a
destiny written in the stars,
All action is initiated from
the space port on the Rebel
flagship Independence. After
pilot registration — incorporat-
ing the game's unobtrusive,
manual-based copy protec-
tion — you're presented with
several paths to follow. Pilot
Proving Ground is the logical
first stop for rookie space pi-
lots, as this is where you'll
learn the fine art of flying the
X-Wing, Y-Wing, and A-Wing
Rebel ships.
You're run through a series
of holographic images that ap-
pear as a maze of floating
gate platforms, twisting and
turning into 3-D space. Each
round must be completed with-
in a set time limit, which be-
comes shorter the further you
progress. This section offers
your first taste of the game's re-
alistic 3-D flight model and
the remarkable control afford-
ed by zero gravity. Complete
all eight courses in a given
ship, and receive an honorary
flight badge.
The next step in your train-
ing leads to the Historical Com-
bat simulator, where you par-
ticipate in re-creations of actu-
al Rebel missions. Six mis-
sions of increasing difficulty
are available for each ship
type, allowing you to practice
various skills in a series of com-
bat, rescue, and reconnais-
sance scenarios. This is also
the best opportunity to familiar-
ize yourself with each ship's
tactical strengths and weak-
nesses. Purely a simulation,
with no impact on your pilot
status. Historical Combat pro-
vides invaluable hands-on ex-
perience in almost every imag-
inable confrontation.
As they say. however,
there's nothing quite like the
real thing. At the heart of the
program are the grueling
tours of duty, three in all, for a
total of 38 missions. You be-
gin the game with the title of
Flight Cadet, with the opportu-
nity to advance five levels to
the rank of General of the Al-
liance Fleet, earning various
medals and awards along the
80 COMPUTE AUGUST 1993
way. Mission types range
from simple patrols arid brief
interdictions to full-scale at-
tacks and defensive stand-
offs. Make it to the final mis-
sion, and you'll re-create Luke
Skywalker's bone-cfiilling
trench run on thie massive
Death Star. Completed mis-
sions are automatically added
to (he historical simulator,
Preflight instructions are ap-
propriately futuristic, featuring
holographic map displays out-
lining mission objectives, ob-
stacles, and w/ay points. Mis-
sions are timed and must be
completed within extraordinar-
ily strict guidelines. Unlike
Wing Commander, where the
story continues as long as
your pilot survives, failure to fol-
low exact rules here results in
a failed mission. Unfortunate-
ly, these rules are murky at
best and are downright enig-
matic at higher levels.
This brings up X-Wing's
most controversial point: In-
stead of being a free-form
combat simulation, it is rigidly
structured, with only predeter-
mined outcomes. Such restric-
tions leave no margin for er-
ror, thus discouraging sponta-
neity and creative solutions.
On the other hand, the game
forces you to stretch the
boundaries of skill and imagi-
nation beyond what simple ar-
cade shoot-'em-ups can offer.
Though this causes X-Wing to
be often outrageously diffi-
cult, the result is replay value
far higher than that of previ-
ous efforts in the genre.
Gameplay is tight, yet fluid,
aided by spectacular graph-
ics and sound effects. Cock-
pit designs are handsomely
rendered in 256-color bitmap
overlays, with 17 different
view angles. Main features in-
clude forward and rear sen-
sors with color-coded identifi-
cation and quick placement
of surrounding craft. The cen-
tral combat multiview monitor
helps you identify enemy
ships, as well as scan for
shield status, damage, and
sections vulnerable to attack.
One of the most useful
skills you must learn is how to
shift your ship's energy
among engines, shields, and
weapon regeneration. An R2
Astromech droid serves as
your copilot, reporting dam-
age, performing repairs, and
providing a communications
link with other ships. It also
allows in-flight access to sec-
tor maps and a review of mis-
sion directives.
Weapon systems increase
proportionally in power and
number with each upgrade in
ship design. X-Wings are
armed with laser cannons
and proton torpedoes, while
the medium-range Y-Wings
come equipped with addition-
al icon cannons. The heavy-
duty A-Wings pack the big-
gest wallop, boasting an ar-
ray of devastating concussion
missiles. Weapons fire with a
satisfying burst of light and
sound. Destroyed alien ships
ignite in breathtaking bitmap
explosions. The fiery destruc-
tion of larger ships is particu-
larly well done, starting with a
chain reaction of small erup-
tions and climaxing in a thun-
derous fireball.
Outside views of all ships
are rendered in solid-fill poly-
gons, a design decision that
pays off with superb 3-D mod-
eling and a smooth, rapid
frame rate, even on slower ma-
chines. Although the publish-
er recommends an 80386-
based system, user-defined
graphics detail allows the
game to run surprisingly well
on a fast 80286 machine. In
addition to LucasArts' iMUSE
interactive soundtrack, users
with Sound Blaster-compati-
ble sound cards will also en-
joy crisp digitized speech.
Few sounds are as chilling,
however, as the unholy roar
of TIE fighters screaming
across your path.
Perhaps the game's most
dynamic and helpful accesso-
ry is the in-flight recorder, iden-
tical to one used in Secret
Weapons of the Luftwaffe.
Combat footage can be
played from almost any point
of view, during missions or af-

Do we have an innate desire
to better humanity? Perhaps
an entrepreneurial drive? Or is
it smply an egotistical desire
to play God? Whatever drives
us, controlling a world with
broad, sweeping gestures
that affect untold numbers of
people is deeply satisfying.
Fortunately, with the aid of sev-
eral excellent games, we can
satisfy the lust for total power
without any of the potentially
dangerous repercussions.
lous II, Civilization (Micro-
Prose) is a tried-and-true
game of civilization building.
The game gives you complete
logistical control over a bud-
ding tribe of Homo sapiens
which has just made the move
from hunter-gatherers to vil-
lage settlers, It's up to you to
guide and develop this fledg-
ling civilization first to world
prominence and, eventually,
to space migration to Alpha

Populous II: Trials of the
Olympian Gods (Electronic
Arts) is a true player-as-God
game set against the panthe-
on of ancient Greece. You as-
sume the prowess of a son of
Zeus and control the fate of a
civilization of loyal worshipers.
The game endows you with
true Olympian abilities, allow-
ing you to raze the land with
the click of a mouse button.
An unfaithful enclave resides
along the coast? No problem,
simply lower the ground into
the sea and be rid of it.
In Populous II you possess
the ability to endow a leader,
from Adonis to Odysseus,
with heroic stature, enabling
him to fight with valor and in-
spire the moral fortitude and
wonderment of his people.
You can mold the world to
suit your tastes as well as com-
mand the devotion and ac-
tions of the petty humans oc-
cupying it.

You get a hands-on. what-if
experience of developing an
entire culture from the ground
up. You literally create the
world and administer labori-
ous tasks, such as building in-
frastructure or protecting the
realm, to the citizens. You can
even cause a revolution that
causes the civilization to shift
from one form of government
to another.
SimCity for Windows (fvlax-
is) is the latest edition of the
best-selling city simulator.
Even more specific in focus
.than Civilization, SimCity con-
centrates your attention on de-
veloping and managing a grow-
ing city. By fully utilizing Win-
dows' power to display simul-
taneous windows of informa-
tion, SimCity allows you to mon-
itor the lay of the land and the
block-by-block details of the
city, as well as a host of
graphs charting develop-

You still have a sense of play-

of this costs money, of

Managing the design and
development of a city or at-
tempting to control one of the
real-world cities included in
the game, you get a feel for
the interlocking nature of hu-
man society and how one
move affects many variables.
In addition to the man-made
variables, you must plan for
and contend with natural dis-
asters such as flooding and
earthquakes — all the while
keeping an eye on the mood
of the populace.
Power mongering: It's an en-
ticing and disturbing human
trait. Thanks to these great
games, we can work through
our delusions of megagran-

with is the very real potential
of addiction. In the words of

^^'^n aqueduct, a castle, and a samurai sword — these three are
yWm icons of the bygone days that we can now experience on our
/^^PCs. The distant past was a time of radically different cultures,
primitive technologies, and, of course, war, In the Roman Empire,
cohorts (divisions of a Roman Legion) patrolled the provinces, repel-
ling the barbarians and maintaining the emperor's sovereignty. In feu-
dal Europe, barons battled barons for papal favors, the wealth of the
land, and a chance to be crowned king. In feudal Japan, the code of
honor known as Bushido governed the samurai, who fought across
rice fields to strengthen the power of their lords.
We can read about distant history because the actions of the
movers and shakers of the time are recorded. But what was it really
like? What was it like to make decisions in a time in which values and
goals were radically different from those of today? Now we can find
out. Several excellent computer games take us back through the cen-
turies and allow us to learn history through action and strategy and to
struggle for success much as the royalty of the time had to struggle to
obtain and maintain power. Beyond being lessons in history, the
games we'll look at offer serious challenges, forcing players to adopt
strategies that fit within the context of the times they simulate.
Caesar
This game from Impressions takes us back to the first century B.C.,
when the first Roman emperor, Augustus Caesar, came into power.
You begin the game with the title of citizen. You are the governor of a
remote province of the empire. You must develop and nurture the
province to prosperity in order to receive a promotion and relocation
to another, more valuable province, With careful planning, proper trib-
utes, and a warlike strategy, you can achieve the ultimate goal: being
crowned emperor.
You're forced to focus mostly on the capital city of the province
and to guide its development. When the game begins, the province is
barren; you find only a few small villages dotting the countryside. A
fort rests where the capital will be built, and a cohort is ready for
patrol duty. The capital is built from the ground up, with the social and
'©y *^aul (T. 3chuytema
political heart of all major Roman
cities, the forum, at its center. tJsing
an interface somewhat reminiscent of
SimCity but far more detailed, you lay
down roads and place residences,
which begin as small tents. Water,
certainly one of the prime require-
ments for any civilization, must be
made accessible, and reservoirs can
be built to trap the water. Aqueducts
can be laid to bring water into the
fledgling city, and a fountain will make
the water accessible.
You continue to develop the city,
enlisting the aid of your advisers at
the forum. They give you advice such
as which industries will likely flourish
in the province and the proper alloca-
tion of the plebs in the work force.
Bath houses, plazas, hippodromes,
coliseums, and schools can all be
built
The city-building aspect of Caesar
is a fascinating voyage into the world
of the Roman Empire. Impressions
has gone to great lengths to make
sure that the type of structures and
the development of the city are in line
with the historical and archaeological
facts. As the city grows, you must
build larger forums to effectively gov-
ern the growing acreage. You get a
real sense of being there.
However, Caesar goes far beyond
the construction of a city. By utilizing
the forum's advisers, you gain insight
into the multitude of variables affect-
ing life in a Roman province, from
conscription service to developing
stronger cohorts.
You must also develop the entire
province, linking the small villages to
your capital via provincial roads and
linking your capitai to the imperial
highway system. The game allows
you to construct grand, sweeping
walls and battlements, and you can
build additional forts that in turn cre-
ate new cohorts .
Eventually, barbarians will rush in
and attempt to capture your capital,
and the cohorts must then be sent to
attack. You control the formations of
the units, and as a conflict progress-
es, losses in numbers as well as
morale are documented.
Soon, Impressions will release
Cohort II, which you will be able to
link to Caesar. This will provide you
with man-by-man control of the battle
using Impressions' microminiatures
gaming system.
As a city management program.
Caesar certainly succeeds, but as an
entire game of provincial manage-
ment in the Roman Empire, it is excit-
ing and addicting — not to mention
exhausting.
B6 COMPUTE AUGUST 1993
9Jledieval Castles
The medieval castie was not a
structure meant primarily for
defense; its purpose was to domi-
nate, A castle could easily influ-
ence lands within a 25-mile radius,
since 30 miles was within a day's
march for the average foot soldier.
During times of attack, peas-
ants, livestock, and property could
be brought into the castle for pro-
tection. The castle walls, as well as
the height advantage for archers
and for dumping all nature of
things upon attacking forces,
meant that an attacker would need
at least a four-to-one advantage to
have any hope of taking a castle.
A castle was not merely the site
of courtly love and stately ban-
quets. The average castle generat-
ed the clamor that our large facto-
ries produce, and people v/ould
have to shout if they hoped to be
heard over the chopping and ham-
mering. A castle, as opposed to
earlier, fortified towns, was not
community property; it was a per-
sonal possession of the king, the
queen, or a baron.
Contrary to what many might
think, the castle was economical to
build. Labor was cheap and often
free, and raw materials needed
only to be amassed. In building a
castle, the greatest cost was time.
After the plague, though, the situa-
tion changed, and labor prices
rose because of the shortage of
skilled craftsmen.
Castles II: Siege & Conquest
A medieval simulation based on four-
teenth-century France, this Interplay
game begins on January 1, 1312, just
after the l^ing of Bretagne (the mythi-
cal France in the game) dies without
an heir. The kingdom is divided into
territories controlled by rival lords who
are all vying for the throne. To
become king, you must unite enough
territories to secure your strength and
then petition the Pope for the right to
wear the crown.
Castles II is a surprisingly addict-
ing game of logistics and aggressive
acumen, making it a task-based
game. This means that you initiate an
action (which takes time to complete)
and then wait for the results. There
are three different general sets of
tasks: administrative, military, and
political. An example of an adminis-
trative task is gathering timber
resources, while a military task might
be recruiting forces, and a political
task might entail sending a diplomat
to demand a tithe from a nval lord.
Managing tasks may seem dry at
first, but there is a real challenge
inherent in the logistical distribution of
task points to maintain an optimal effi-
ciency. While tasks are the main
means of controlling the game, you
also have the opportunity to design,
from the ground up, any of the castles
you wish to build. The castle design
portion of the game is intriguing, and
you can place low or high walls,
square or round towers, gates, moats,
and keeps. You can choose to build
the castle walls first or construct the
keep first. If you design a truly mag-
nificent castle, you can save the
design for future use.
In Castles II, not only is a castle a
defensive tool, but it also assists in
nearly every aspect of the game. A
large enough castle will keep neigh-
boring territories from revolting and
can double the production rate of the
territory's commodity.
Combat can be handled as a com-
puter simulation, or you can choose to
make all tactical decisions on your
own, controlling each knight, archer,
or infantry unit individually.
Diplomacy and careful planning
are the keys to victory, but your for-
tune may change unexpectedly due
to some developing plot or rival
alliance. Also, good relations with the
papacy are imperative, since only the
Pope can legitimize the crown.
Castles II is a good-looking game
in which most of the action occurs on
a single screen. The only time the
screen shifts views is during a tactical
battle or when you choose to visit a
territory to build a castle or check on
its progress. The game also features
a series of video clips which accom-
pany important actions, most taken
from the sweeping black-and-white
epics of the 1930s and 1940s,

Conquered Kingdoms
QQP's ancient history entry is a
medievaf war game in the same vein
as the popular Perfect General series.
You battle either the computer or
another player (live or via a modem
connection) in a game of geographi-
cal conquest.
In Conquered Kingdoms, you con-
trol units which represent a group of
individuals such as archers or
knights. Each scenario begins with
the selection of troops, using points to
buy units and place them on the mul-
tiscreen map.
The game progresses in turns,
enabling each side to move. Then,
the battles are resolved, At first,
Conquered Kingdoms seems a cryp-
tic and abstract war game, but after
severai turns, the depth truly comes
through. Resources need to be cap-
tured and managed, as do castles
and towns. By carefully managing
resources, you can create reinforce-
ments that can be placed in any cas-
tle you hold.
Conquered Kingdoms is a game of
details and careful planning, and a
single scenario can easily last many
hours. The excitement of controlling
an entire army, piece by piece, in a
giant medieval chess match, grows
with every turn, and the ability to con-
trol units in a semitactical sense
allows for strategies regarding forma-
tions and the development of lines of
strength. By making the scale much
larger than an actual one-to-one cor-
respondence, you have the opportu-
nity to react to and use a myriad of
terrain types and to cover a lot of land
in little time.
QQP is noted for games that pos-
sess simple yet sophisticated inter-
faces, and Conquered Kingdoms is
no exception. Virtually every action
can be handled by intuitive mouse
clicks, and the program takes care of
all of the dirty work (like movement
restrictions) by means of various ter-
rain types and enemy lines of sight.
The game truly allows you to concen-
trate on organic strategy rather than
on rules or icon manipulation,
Because of the depth and chal-
lenge of Conquered Kingdoms, it will
be a long, long time before you'll be
able to master all the scenarios and
the incredible complexity of the artifi-
cial intelligence of the computer
opponents. Playing against a human
opponent is even more rewarding,
and it's especially exciting when you
are playing by modem and seeing
only the results of your opponent's
actions (but you might want to find a
local opponent or play through
88 COMPUTE AUGUST 1993
CompuServe's MTM service to save
on phone charges for the lengthy
calls). You can even play opponents
by E-mail, utilizing a special save fea-
ture of the game.
Conquered Kingdoms also has an
option that, while not exactly true to
historical fact, allows you to control
fantasy units such as trolls, dragons,
and wizards.

history as you

addicting games of
strategy.
Conquest of Japan
A tactical simulation of samurai con-
quest from Impressions, Conquest of
Japan brings sixteenth-century Japan
to fife. The game consists of a battle
between two daimyos (lords) on the
main Japanese island of Honshu,
each controlling five cities — and each
wanting total control of all ten cities.
One player can compete against the
computer, or two players can go head
to head.
The game is somewhat reminis-

cent of the excellent Milton Bradley
board game Shogun, but it features
an extremely detailed combat system.
The overall strategies of the game are
straightforward: The game begins
with the recruiting of five armies and
the decision as to what portion of the
forces to leave behind to defend the
cities.
Movement of the armies is a sim-
ple one-step-at-a-time sequence until
two armies run into each other. During
the course of the campaign, the
towns collect revenues that can be
used to recruit more troops.
Conquest of Japan comes alive,
though, when two armies meet for
battle. Utilizing Impressions" own
microminiatures system, the battle is
played out at a truly tactical level. The
first step for a battle is to select one of
the traditional troop formations, from
the all-around Ganko (birds in flight)
to the defensive Gyorin (fish scales).
The view shifts to an overview of the
battlefield, and orders can be given in
nearly any combination or detail
imaginable.
The interface allows commands to
be given to individuals, to a group
(such as a line of spearmen), or to the
army as a whole. Communication is
important on the battlefield, and
groups of troops must have a signal-
man to follow your orders. If a signal-
man is killed, another must be
assigned, or you risk losing the units
due to noncommunication.
During the battle, all manner of
information is available to you, such
as morale and current attack strength.
Perhaps the most powerful feature of
the battlefield controls is the ability to
alter, split, and regroup your forces
into any of 24 formations.
The incredible depth of tactical
control takes a while to get used to,
but complex and effective battle
strategies are the result of a little
patience. You can achieve the gen-
uine feeling of commanding a six-
teenth-century samurai army.
In the Present Tense
By combining many levels of game-
play with historical accuracy, these
games can truly be windows into sev-
eral very exciting eras of our ancient
past. Each of these games plays with-
in the rules of its respective time peri-
od, allowing you to step back and
enjoy the decisions and challenges of
those times while learning about the
limitations and advantages of a multi-
tude of tactics and technologies. A
weekend spent in ancient Rome,
medieval Europe, or feudal Japan can
become an educational addiction. □
64/128 VIEW
A veteran 128 publication turns its
editorial eye on the 64 with the launching
of JwiD Cities 128/64.
Tom Netsel
Gazette celebrated its
tenth anniversary
wlien the July issue
rolled off the presses.
That's almost 120 issues.
(We missed a couple during
the summer of 1990.) HUN
made it to issue 99 before it
closed its final page.
Computer magazines
come and go, and those
that hitch their editorial wag-
ons to one machine often
experience a meteoric ride.
Some flash onto the scene,
burn brightly, and then fizzle
away: while others maintain
a steady glow.
Gazette started its associa-
tion with the 8-bit Commo-
dores by focusing on the
VIC-20 and the 64, adding
coverage of the Plus/4, 16,
and 128 when those ma-
chines came along. When
the 64 and 128 emerged as
the leaders, we followed the
numbers and concentrated
our coverage on those ma-
chines. Surveys tell us that
70 percent of you own 64s,
Few publications have de-
voted coverage exclusively
to the 128, Twin Cities 128
was the exception. Founded
by Loren Lovhaug in 1985,
TO 128 was primarily a tech-
nical publication that ap-
pealed to 128 program-
mers. It had its fans, but
they were not enough to
keep it in operation. It fold-
ed in 1991.
And then along came
John W. Brown, president of
Parsec. He bought the
rights to the magazine a few
months iater and resumed
publication. Coverage at
that time was still limited to
the 128.
When RUN died last
year, Brown figured that his
publication should offer
some support to 64 owners
in addition to the 128
crowd. So with issue num-
ber 33, Brown launched the
new Twin Cities 128/64. Pro-
duced on a 128-D with a la-
ser printer, TC 128/64 de-
votes about half of its 56 pag-
es to each machine. Look
for reviews, articles, GEOS in-
fo, and technical pieces, but
don't expect a large number
of type-in programs.
The cost for U.S. subscrib-
ers is S24 for six issues. The
magazine and companion
disk cost $40. To subscribe
or for more information,
write to Parsec, P.O. Box
111, Salem, Massachusetts
01970-0111. You can also
write for a free copy of the
magazine.
In addition to Twin Cities
128/64, Parsec offers a vari-
ety of disks, fonts, GEOS
graphics, and other prod-
ucts for 64 and 128 users.
SIDplayer fans should note
that COMPUTE has sold the
exclusive distribution rights
to the book and disk to Par-
sec. That book/disk combina-
tion should be repackaged
and for sale by now.
In "Upgrading Without
Changing Platforms" (June
1993), it was reported that
Parsec had dropped plans
to produce a board that
would let a 128 operate at 6-
12 MHz. Well, that wasn't en-
tirely accurate. Brown told
me that the company work-
ing on the prototype had
dropped it, but he stiH in-
tends to produce it — and
one for the 64 as well.
Brown says the product
is now an external cartridge,
CMD compatible, that will
plug into the expansion
port. It wilf probably use a
65C816 chip and operate at
12 MHz. The cost is expect-
ed to be about $200. D

Writing is a solitary activity, but it
doesn't have to be a lonely one
if you use your computer to network
^ I with other writers.
By Karl Witsman
# - . *
If you're a writer, you know what kind
of power a computer gives you —
power that you never had with a
typewriter. But if you use your 64 only
for word processing or the occasional
game of Space Invaders, you haven't
explored its most powerful use.
There's a great force out there just
waiting for you to tap into it with your
computer and modem. It's caliec net-
working, and it can multiply your com-
puting power and help your writing!
Mosi folks using computers have
heard of BBSs or bulletin board sys-
tems. The popular notion of a BBS run
by a teenaged hacker may have
some validity, but many systems are
run by serious computer enthusiasts,
computer clubs, schools, and bus-
inesses. Some are created for fun;
others have a more serious intent. All
require a modem to connect your
computer to a telephone line.
Running any BBS can be trouble-
some and is definitely time-consuming
for the owner or system operator
(sysop). These are labors of love,
since most BBSs bring in no money.
Sysops usually appreciate any help
they can get, even if it's only through
the messages posted by callers, but
volunteers can help in other ways as
well. Many boards have areas devoted
to special topics, and often these
areas are directed by outside sysops. I
have volunteered on more than one of
my local boards to form a writers' area.
This is a place where local writers can
converse about literary topics, and this
is the place where networking comes
into play.
To share the fun and information,
try to find a BBS in your local area.
If you can't locate one v/ith a
writer's BIG, here are some you
might want to try. Several of these
BBSs have specific writing areas.
Alt allow access up to at least 2400
bps and run 24 hours.
• Almost Paradise, Oakwood,
Illinois: (217) 354-4711. The sysop
is Chhsty Blew. Leave a message
for Karl Witsman, user number 56.

mation, I'll reply with it here.

everywhere, call (913) 478-9239.
Write Here
On a BBS, writers can discuss any-
thing, such as the mechanics of manu-
script preparation, agents, who us-
es/hates outlines, how to query about
possible articles, or how to deal with
deadlines, Some topics are even more
involved, such as "Where does this sex
scene fit into the story?" or 'How do I
show my character's thinking process-
es?" For questions that have no simple
answers, the opinions of other writers
can often prove helpful. If you're not a
member of a writing group that meets
in person, this electronic connection
may be the only way to pick the brains
of others in your field.
Three Approaches
There are three main ways to con-
verse on a BBS. The first is simply to
leave a message in a general mes-
sage area and let other callers read
and respond to it. In most cases,
other callers can respond on the
same message area or send you a
private reply through electronic mail.
The second method of exchanging
information with other computing writers
is through SIGs (Special Interest
Groups}. As their name implies, these
areas concentrate their focus on a spe-
cific topic of interest and one could be
devoted to writers.
Echo, Echo
The third, and most sophisticated,
method of communicating on local
BSSs is Echo messaging, Echoes are
a number of BBSs that form a net-

work. Most of these networks are set
up by sysops who know sysops in
other towns. Using this system, a
writer in Connecticut might leave a
message on his or her local BBS.
Around 3:00 a.m., the Connecticut
BBS might call a BBS in New York
and exchange messages, being care-
ful to keep the writing messages
separate from those dealing with
computers, sports, and other topics.
The New York BBS might then call a
BBS in Ohio and repeat the process.
In this way, the messages echo
around the country.
When I cail my local board, I can
read the message posted by the Con-
necticut writer and respond to it. Writ-
ers all around the country have an op-
portunity to respond, and these
responses are entered into the net-
work. In a day or so, after the BBSs
exchange messages again, the
Connecticut writer can read the re-
sponses, as can all of the other writ-
ers on the network.
One such echo is the National Writ-
ers Echo. I was a local monitor here in
Danville, Illinois, on the Friendship
BBS, which was run, before his death,
by Terry Claybaugh, Through this net-
work, I exchanged messages with
many writers of varying degrees of
fame, including Billie Sue Mosiman
(author of Wire) and John DeChancie
(author of the Starrigger series and the
Castle Perilous series).
Such free exchanges of infor-
mation and opinions with other work-
ing writers can expand your knowl-
edge and help you keep track of up-
to-the-minute publishing trends. All
messages and mail are automatically
date-stamped, so you can ignore old
information and be aware of the most
recent updates and changes.
REF# 432
POSTED: 04-20-91
FROM: Karl R. Witsman
TO: All
Writers. I'm steaming mad! The U.S.
Copyright Office has raised the copy-
right fee from SW to $20 to register
our works! This may be fine for those
who write nothing but bool<s, but for
those of us wishing to register short
stories or articles, it's an outrage.
Next time we must no! let this happen:
next time we must unite and apply our
skills in written communication in let-
ters to the Copyright Office, Con-
gress, and the president At five cents
a word in a pulp publication, it takes a
lot of words to earn $20. Let them
charge bigger fees for books, and
even bigger fees for screenplays thai
are being produced into movies, but
leave writers of features some slack. If
you would like to vent your spleen, as
! just did, be sure to talk to the right
people — those at the following
address: Copyright Office, Library of
Congress. Washington. DC 20559.
As you can see, a BBS can also be
a good way to blow off steam and let
others know how you feel about
trends in the field. Let's face it, writing
is a solitary profession, but it doesn't
have to be lonely if you can reach out
and telecommunicate with someone.
Bigger and Better
Commercial online services are the
big alternatives to local boards. These
are not custom networks, but gigantic
groups serving thousands of
subscribers with varying interests. As
the word subscriber suggests, these
services cost for membership.
Some examples of such services
are DELPHI, CompuServe, Quantum-
Link, America Online, GEnie, and BIX
(Byte Information exchange). Each
service has its own pricing structure
and fees, so a call to each would be a
good idea for potential subscribers.
Practically all of the major services
have at least one area designated for
writers. In some, you post a message
as you do on a local BBS and then
return in a few days to •'ead the
replies. Many services also offer areas
for immediate writing discussions. This
Have you ever written an article and
then spent months mailing it from
publisher to publisher? Now you can
submit your manuscripts electroni-
cally through a groundbreaking step
in publishing by Manuscript Mar-
keting Technologies Incorporated.
MMTI is not like other BBSs and
online services. It offers writers a
unique opportunity to submit articles
or stories which are then offered to
publishers electronically. More than
500 authors from all over the world
have availed themselves of this ser-
vice so far, as have 140 publishers
from the U.S. and Canada.
Submissions can be made
through special software for IBM
compatibles which automates the
process and records the article or
story on disk. Macintosh users can
use Microsoft Word format, which is
then transferred to ASCII and then
into the IBM-compatible program.
Manuscripts submitted on paper are
scanned through optical character
recognition (OCR) software.
Publishers can call MMTI's com-
puter and set the parameters for
what they're looking for in a manu-
script. Let's say a publisher needs
an article on homeless persons that's
about 2000 words long. The publish-
er specifies the subject, length, and
format (article, screenplay, book),
and the software displays only those
works meeting the criteria. Within the
fiction category, there are 26 differ-
ent parameters, and there are 323
categories in nonfiction.
When a publisher finds an article
that meets the criteria, the manu-
script can be locked so that no other
publisher can get it. The service then
gives the publisher information about
how to contact the writer. The pub-
lisher and writer then work out a
deal. Once the two parties come to
an agreement, the publisher can
download the work into the publish-
er's computer. Little or no paper
changes hands. Only the original
disk and contract have to mailed.
If you're a writer who's spending a
fortune on postage in mailing heavy
manuscripts from publisher to pub-
lisher, this service might be the
answer. It's also a good way to make
simultaneous submissions for time-
sensitive material. Each month, the
writer gets a report of how many
times the article was read and why it
might have been rejected. This gives
the author a chance to judge if the
work needs further revision.
The cost is an initial S25.00 fee
and $10.00 per month. There is a
storage charge of S.0001 per word
per day, (A 6000-word piece would
run SI. 80 a month.) There is also a
$2.00 fee per disk . When compared
to postage to mail the manuschpt to
140 publishers, this is a very good
deal. (Just sending a query letter to
all these publishers would run
$40.60!)

mation about its services, write to

Remember, MMTI does not act as
an agent, and it cannot offer you
advice. The company merely offers
storage and a distribution service.
The software does not handle graph-
ics or photos, but authors can leave
a note in the manuscript if photos are
available.

tion or comment wtiicti, is distributed im-
mediately to ail of the users who are
signed on in the area. In this way,
dozens of writers can respond to your
comments or questions within seconds.
I host such an area called the
Writers' Forum on QuantumLink. the
Commodore-specific service. Up to 20
writers meet in realtime once a week in
either a lecture or discussion format.
If you still wonder about how an
online forum can help you with your
writing, here are comments from
some of the writers who frequent Q-
Link's forum.
"The Writers' Forum keeps me
motivated. When I run out of ideas,
the group fires me up! It's a great
place to tall< to people all over the
country who share a love of writing,"
says Marti Paulin.
"If I didn't have the online forum,
I'd have to drive 20 miles each way at
night to get to my local group," says
Cheryl Turney.
"Where else can I talk with people
as insane as I am, from all over the
country? Seriously, the forum offers
me a great place to tall< about what a
writer goes through, with people who
understand," says Eric Lopkin.
"The forum fires my creative
juices — and adds to my degenerate
vocabulary." says Donna Carlene.
"It's fun to chat with folks as poor
and stubborn as I am," says Alex
Tishcenko,
"I enjoy the writing contest. It forc-
es me to come up with things on a
regular basis," says Mike Cervini.
Even though I'm a forum leader
and editor of "The Writer's Newslet-
ter," I still learn something from
speaking with other writers. We've
also been fortunate enough to have
guest speakers such as Arlan
Andrews, Poul Anderson, and
Lawrence Block drop in to answer
questions and give writing tips.
Occasionally an editor such as Eric
Lopkin (Lopkin Publishing) or Tom
Netsel {COMPUTE'S Gazette) will stop
by to offer advice. And remember, the
Whters' Forum on Q-Link is only one
such network. Imagine what joys
await you elsewhere. (See "Writers'
Forums" for additional information.)
Commissions and Submissions
On the national services, you never
know when you might speak with an
editor who's loo!<ing for someone to
write an article, and it could be a topic
with which you're familiar. At other
times, an online conversation might

I remembered
Our old phone number.
Like a long ago children's
rhyme
It came back to me.
I recall phoning late —
On the road, still
To tell you
I'm OK: I'm alive.
Sometimes breathless,
Sometimes angry.
You'd tell me
— hurry home.
A machine tells me that the
number
Is disconnected
And I wonder
Who calls you now?
But more.
I wonder
Why I want to

into tlie Future
Computers are the writing tool of the late
twentieth century, but networks are play-
ing a major role as writing moves into the
twenty-first. If you write with a computer,
you owe it to yourself to use this tool as
something other than an electronic type-
writer. Use it to exchange ideas with
other writers, conduct research, submit
articles and ideas to publishers, get
feedback on your work, and more.
You could never have this amount of
pov/er with a typewriter aione, so har-
ness this power and put it to work for
you. Writing is an ancient art, but the
tools and technology associated with it
are still growing. Don't be left behind! u

KEY[K)S VERSION 2
Version 2 of KeyDOS Function ROM
for Xhe 128 is simiiar to DOS for IBM ma-
cfiines in ttiat it lets you change drives
easily and defaults to tfie chosen
drive until cfianged again. KeyDOS
ROfvl is a chip that contains 20 func-
tion key definitions and 20 utilities.
It includes Swapper, a utility that
lets programmers work on one pro-
gram in memory, call up KeyDOS to
work in another program, and then go
back to the original program. There's
1581 Visual Partitioner, RAMDOS,
GEOS SuperRBoot, Video Manager,
and Hexpert. The main advantage to
the KeyDOS program is that it makes it
easy to switch drives.
I was happy to find that installation
was easy. It took 5 minutes to take the
128's case apart, 2 minutes to install
the chip, 15 minutes to vacuum out cat
hair — hey, might as well while you're
there — and 4 minutes to put the case
back together. Subtract 15 minutes
from this if you don't own a cat. In oth-
er words, this doesn't take long to in-
stall, even for a nontechnician like me.
On boot-up, the screen will say HOLD
ALT KEY DURING RESET OR SYS
65366 TO ACTIVATE KEYDOS ROM.
Position cursor over the SYS line, hold
Alt, and press Return. You'll get a cop-
yright notice from author Randy Win-
chester and a message telling you
that KeyDOS is installed. Here's a list
of how KeyDOS programs your func-
tion keys and some other cfianges.
f1 — Load program
f2 — Run program
f3 — Disk catalog
f4— Run 64 program
f5— Type SEQ file
f6— Scratch file
f7 — Nev/ active drive
f8 — Scratch and save
Run — Boot disk/file
Help — Drive #
The Esc key offers many new com-
mands when used in conjunction with
other keys. Commands include Help, a
compiler, a 1581 partitioner, a subdirec-
tory key a batch exec key GEOS Su-
perRBoot, CBfvl RAf\/IDOS, Diskmon, a
monitor dump, Hexpert, a drive renum-
berer, an UNNEW command, a screen
G-10 COMPUTE AUGUST 1993
dump, find and replace, an alternate
screen, and more. KeyDOS is very use-
ful for running a directory and for run-
ning some programs. It's also cool for
checking out SEQ files. It allows you to
scratch an old file and rewrite a new
file in one easy command. If you load
it when you first power up, you can ex-
amine what's on a disk without loading
an extra program.
The program goes downhill from
there. I had trouble with the lockups
and syntax errors. I needed to reset
the 128 almost every third time I at-
tempted different commands. The pro-
gram includes a demo disk, but it
wasn't helpful. It lists nine programs
and four sequential files, but I was ei-
ther denied access or else the 128 lock-
ed up whenever i tried to load or run
the programs.
Two programs, Write-SEQ-File and
Write-List-File, for instance, both tell me
that I have no room. I must delete a
function key's programming and repro-
gram a key for these programs, but the
manual isn't helpful in telling me how to
do this. There are two separate func-
tion keys for running 64 and 128 pro-
grams. Unless you keep the 64 and
128 programs on separate disks,
there's no way of telling a 64 program
from a 128 program. Having both
types on one disk gives me an error
message and forces me to reboot eve-
ry time I choose the wrong program.
The manual doesn't say which RAM
expansion units work with KeyDOS.
Since GEOS is the center of my world,
I used geoRAM. I tried it and was told
to put Desktop 2.0 on the REU, which
I had already done. KeyDOS may
work with another REU, but not with
geoRAM.
Don't worry if programs or files
scroll off the screen when a directory is
being listed. Go into Utility with Esc-1,
and you have a lot of help at your fin-
gertips. KeyDOS has 18 utilities; for-
ward, back, select, unselect, toggle se-
lection, select all, copy, select drive,
directory, new disk/list, print, quit, re-
name, scratch, type, unselect all, 1581
subdirectory, and drive command.
Type, for example, sends SEQ files to
the screen in PETSCII, true ASCII, and
Screen mode.
This utility is great for renaming
files, scratching files, and printing
files, but it requires you to call up the
directory again. The program doesn't re-
display the directory by itself, but this
is a small point.
I gave an incorrect command to
print, and then realized my printer was
not hooked up. The program kept tell-
ing me to redo from the start or enter
a device number. It would have been
handier to default back to the program.
As it was, I had to reboot yet again.
The compiler allows you to reassign
functions to different function keys. You
can save any new configuration to
disk and reload it the next time you
wish to use it. The 1581 Visual Partition-
er lets you not only format a disk but al-
so add a partition to a previously used
disk.
The monitor dump sends the moni-
tor output to either a PETSCII disk file
or a PETSCII printer. Diskmon and Hex-
pert should be very useful for machine
language programmers.
With KeyDOS you can renumber
drives, reset drives, run new collect, res-
cue a deleted program, execute pro-
grams on the alternate screen, install a
find/replace/scroll utility, execute a one-
drive routine, and run Screen Edit,
Clock Manager, and Video Manager.
With Video Manager, you can
change the cursor's shape, flash rate,
and blink rate. You can use an inter-
laced monitor, and you can select
from 80 colors for text and back-
ground. The colors appear only as
shades of gray on an RGB monitor. It's
also possible to change the back-
ground and text to the same color, mak-
ing the text invisible. This can cause
panic city the first time you do it. be-
fore you figure out how to undo it. Be
prepared for massive button pushing.
I had to press f3 at least twice and
sometimes three times before I could
call up a directory When I accidental-
ly changed both text and background
to the same shade of gray, it took
three pushes to change the color Of
course, there's the good old reset but-
ton (unless your screen is totally gray).
KeyDOS is a specialized product that
will appeal to some users more than oth-
ers. Average users like me probably
won't find it as useful as programmers
will, If you're a programmer, you'll prob-
ably love KeyDOS.

RISERS AND SLIDERS
Step right up and grab a Slider! Hop
on board and tal<e a ride! No, I'm not
talking about a new skateboard; I'm talk-
ing about a new game from Micro-
Storm tliat's called Risers and Sliders.
When I first heard the name, I must
admit, the first thing I thought of was
the children's game Chutes and Lad-
ders. Then, I booted up the game and
discovered a maze that vaguely resem-
bles the mouse-shaped symbol that
the Disney channel uses as a logo. Kid
stuff, I thought again. However, when
I began to play, I quickly saw how
wrong I was. This game is definitely not
geared to the preschool crowd.
Risers and Sliders is an arcade ac-
tion game that offers 50 increasingly dif-
ficult levels of play. The game's title
comes from the red-colored Risers and
the blue Sliders that you use to move
swiftly around the screen. The Risers
move your character up and down; the
Sliders move you from side to side.
There are also wedge-shaped Sliders
that are a cross between the other two
transports. They move more or less di-
agonally on the screen. Of course, you
can also walk your character from
side to side, but he can't jump or
climb. Using combinations of the trans-
ports and walking, your goal is to
move through the mazes, gather all the
diamonds in each, and build up your
score.
It's not nearly as easy as it sounds.
Learning how to move around takes
practice. You have to move your man
over the transport and press the fire but-
ton while moving the joystick handle in
the direction you want to travel. If you
have good joystick skills, you'll proba-
bly learn the game faster than I did. I
have a tendency to overshoot the
mark when I'm using a joystick. Do,
that in this game, and you'll fall to your
death. Even my joystick jockey teen-
ager had to make several attempts be-
fore clearing a level.
For one thing, there's the pesky little
critters called moths that can sneak up

on you. They move around the screen
unfettered by transports and can
pounce rather unexpectedly. Their
bite is deadly to you, and you have on-
ly three lives to lose. You can evade
the moths, or you can attempt to kill
them. You do that by smashing them
with your transporter. It's worth attempt-
ing a kill since you'll earn an extra life
if you manage to dispose of 12 of
them. You'll also add five points to
your score for each one of the moths
you eliminate.
Another danger when traveling
through the mazes is falling. Be care-
ful where you step! One false step
and— BOOM! You've lost a life. In the
more advanced mazes you'll also
need to know whether or not it's safe to
take the diamonds. You'll soon discov-
er how disastrous it can be if you
guess wrong. By the way, you get one
point for every diamond that you col-
lect. Whenever you earn 200 points,
you will get another life.
The screen border helps you keep
track of how well you're doing. In addi-
tion to the typical score information, the
border flashes whenever you earn an
extra life. It flashes blue for earning a
bonus life on points and red for earn-
ing a life for slaying those pesky
moths. You'll want to get as many
lives as possible because the dangers
increase as you advance in the ganne.
With 50 levels, this game is quite a
value. Some levels are complicated;
some are deceptively simple. Each has
its own dangers. The game's designer,
Daniel Lightner, knew how challenging
the game was, so he programmed in
bonus points for you at the end of eve-
ry level. You'll get 600 points if you fin-
ish a maze in one try, 400 points for
two tries, and 200 points for three at-
tempts. If it takes you more than three
attempts, you get zip, I played a lot of
practice rounds (my name for games
in which I died} before I earned any bo-
nuses. Maybe you'll do better. The
game will keep you busy for several
hours.
That reminds me. Did I mention the
clock? Well, that's another little surprise
the designer added as a booby trap.
You have to complete each of the maz-
es in five minutes or less. Now five min-
utes may sound like a lot of time to
you, but you'll be surprised how quick-
ly it will pass. Trust me on that, t lost
more than one life running around the
mazes, avoiding nnoths, and forgetting
about the time. I soon learned to keep
a closer watch on my time.
Lightner tried to pack the screens
with as many diamonds and obstacles
as he could. However, I believe he
could have done a better job on the
graphics. Risers and Sliders doesn't re-
ally utilize the screen as welf as it
could have. The transporters are depict-
ed as minuscule squares just a couple
of pixels wide. Only their colors desig-
nate them as anything special, The
moths are a couple of tiny, intercon-
nected loops. The fact that they were
moving told me they were supposed to
be the deadly moths. Even your char-
acter is little more than a stick man
that moves. I've seen better graphics
on a 64.
The attraction in Risers and Sliders,
however, isn't the art. The difficulty of
the game is its charm, i suspect once
you discover this program, you'll keep
coming back for more.

FEEDBACK
Updates and
corrections to
earlier
programs, a
program
that calculates chess
rankings, and more
Bug-Swatter
Steven Bakke noticed that
Fastball (January 1993) high-
lights the wrong item when he
makes a selection from the
menu. To correct this prob-
lem, load but do not run the
program. Then, type POKE
2133, 201 and press Return.
Save this corrected version
with another filename.
James T. Jones of Klon-
dike, Texas, points out an er-
ror in the April "Programmer's
Page." When you run Sequen-
tial File Printer, you'll get a
FILE OPEN error message if
you select the Print File op-
tion. To correct it, change
line 190 to read as foilows.

In the May issue, we pub-
lished a review of Video Digitiz-
er that is distributed by RIO
Computers. At the end of the
review, we inadvertently pub-
lished the company's old ad-
dress. The correct address is
RIO Computers, 3310
Berwyck Street, Las Vegas,
Nevada 89121; (702) 454-
0335. We regret the error.
In "Screen Gems" (May
1993), several readers spot-
ted typographical errors in var-
ious program listings. Bill
Gisonda of Bethpage, New
York, noted that lines 230 and
240 of Brownian Symmetry
should be numbered 250 and
260 respectively. Also, lines
150 and 230 should read as
follows.
150 IF Y > 100 THEN 80
230 DRAW, (160=X)A/,100-Y
Donald Klich of Mount Pros-
pect, Illinois, spotted other ty-
pos, which just goes to show
what can happen when type-
setters have to enter listings
without the aid of The Automat-
ic Proofreader. Curve Explo-
sion would look better if line
10 were entered as follows,
10 COLOR 1,2: COLOR 0,1:
COLOR 4,1
In Trig Show, lines 270 and
280 had some problems with
an extra colon and a missing
Return. The lines should read
as follows.
270 IF BB=0 THEN DRAW ,

Chess Ranking
I would like to start a chess
club, and I have been looking
for a program that calculates
club members' chess rank-
ings. Could you give me
some help with a program?
VINCENT SULEWSKI
SOUTH HADLEY, MA
Here is a simple program
that calculates rankings after
players have completed ei-
ther one or a series of
games. As players compete,
they should keep tracl< of the
number of games they play;
their opponents' rantdngs:
and their overall score for
wins, ties, and losses.

Scratched Commas
In the March 1993 "Feed-
back," you told how to
scratch a filename that ap-
peared in a disk directory as
a comma. Your methods are
fine, but there is a much sim-
pler method. Simply enter the
following line.
OPEN15,8,15."S0:?":CLOSE15
This question mark wildcard
will erase any file whose
name consists of but a single
character.

Thanks to Al and all the other
readers who replied with this
simple solution that slipped
Gazette's collective mind.
Just check the directory first
to see if there are any single-

character files on that disk

Interest Calculations
As an active participant in
IRA distributions, I was very in-
terested in IRA Minimum Dis-
tributions (April 1993). I was at-
tracted to lines 980, 990. and
1000 where the interest calcu-
lations take place.
Years ago, I got involved in
interest calculations, especial-
ly after I read in a mathemati-
cal journal that it was impos-
sible to calculate daily com-
pound interest (yield) except
by the one-day-at-a-time meth-
od, as used in the article.
As an engineer, I find the
word impossible to be incom-
.prehensible, so I devised a
means for making long-term
calculations easy. As pub-
lished, the calculation for a
sannple 20-year projection
and its 20-year payout sched-
ule takes nine minutes and 42
seconds. With my revision,
the same calculation takes on-
ly 7 seconds.
Insert REM after line num-
bers 980, 990, and 1000 to
preserve the original code
and then enter this line.
985 SP=SP*EXP(1)T(365.25
*LOG(1+IRfl65.25))+.001:
SP=INT(SP*100)/100:
RETURN
The 365.25 allows for the ex-
tra day in a Leap Year.

Machine Language
Over the years, your maga-
zine has carried a column for
machine language program-
ming; however, I haven't
seen any instructions on how
to actually impiement the infor-
mation. Is a special program
required?
EARL WOODMAN
DILrXJ, NF
CANADA
When you start learning ma-
chine language, the first
thing you need is an assem-
bler An assembler is to ma-
chine language what the BA-
SIC programming language is
to programming in BASIC. It
translates your commands in-
to numbers that the computer
can understand and use.
Since it's difficult to write a
program entirely in numbers,
an assembler replaces the se-
quence of numbers with stan-
dardized mnemonics, com-
mands that humans can more
easily remember and under-
stand. Here's an example.
10 * = 880
20LDA#147
30 JSR 65490 40 RTS
In this short program, when
you enter SYS 880, the com-
puter's screen clears. The
147 is the number which
clears the screen. LDA is a
mnemonic that means Load
the Accumulator a special ar-
ea in the computer So 147
goes into the accumulator,
and the program moves on to
the next instruction. JSR
means that the program then
Jumps to Subroutine at
65490. which is the address
in ROFv! which prints whatever
character is currently in the
accumulator The screen
clears, and the program
moves on to RTS. This com-
mand. Return from Subrou-
tine, causes the computer to
leave machine language and
return to BASIC.
This program Is called
source code, but you cannot
run it as you would a BASIC
program. The assembler
takes this code and turns it in-
to object code, poking num-
bers 169. 147. 32. 210, 255.
and 96 into memory locations
880-885
The computer doesn't
have any idea what to do
with LDA, but when LDA is
converted into 169, it knows
to load the accumulator It's al-
so easier to remember LDA
than 169. The 32 means JSR,
2 10 and 255 is a two-byte ad-
dress that represents 65490,
and 96 returns the computer
to BASIC (RTS).
For those who don't have
an assembler we often print
the code in the form of a BA
SIC loader The computer's'
ML instructions are in the DA-
TA statements.
10 FOR A = S80 TO 885
20 READ D; POKEA.D
30 NEXT
40 SYS 8BD
50 DATA 169,147,32,210,255,96
As with most Commodore
software, finding a good com-
mercial assembler such as
Commodore Macro Assem-
bler Buddy 64. or Merlin64
may be difficult these days,
but a number of public do-
main programs are available.
Gazette's own BASSEM (April
and May 1990) is still availa-
ble on the Best of Gazette Util-
ities Disk ($13.95).
Resume Typing
I have some suggestions
which might help Jack Christ-
law, who was was having dif-
ficulty entering programs in
one typing session,
Whenever I wish to stop typ-
ing, I save what I have using
the number of the next BASIC
or ML line of code as the file-
name. This assures that I'll nev-
er use the same filename
twice and I'll always know
where to begin again. I also al-
ways use a fresh disk with on-
ly fvlLX or Proofreader on it.

AND MORE
QuantumLink isn't the only
place to find shareware and
public domain files, but it's
probably the best place. Q-
L[nk has more files than any-
body else — plain and simple.
I have a copy of its catalog
of files, a burly tome close to
two inches thick and heavy
enough to keep the door to ny
computer room shut against
my one-year-old. This hernia-
inducer makes a valiant effort
to list all 35,000 of Q-Link's pro-
grams and files. Yes, 35,000!
fvlake no mistake; if you're se-
rious about your Commodore,
you belong on the Q.
If you aren't a Q-Linker,
though, you can find good PD
programs on any BBS that sup-
ports the Commodore. Ttie
Rogue River BBS in Grand Rap-
ids, Michigan, has all the files
mentioned in this column. The
phone number is (616) 361-
8267. Of course, all programs
mentioned here are also on Ga-
zette Disk. Here are my PD
picks for this month.
Mille Bornes
Original author unknown.
QuantumLink filename:
rvllLLE BORNES. 3; uploaded
by RolfB.
I seldom play fviille Bornes. My
wife and I bought it about ten
years ago, and it's a great
game. The problem is that I
play it for blood, which is the
way my wife plays Monopoly.
That's why we don't play Mo-
nopoly either, So when I
found this one-player card pro-
gram buried in the 64 games
section of Q-Link, I got all ex-
cited. Now I could stomp some-
one at Mille Bornes without hav-
ing to sleep on the couch!
This version of Mille Bornes
isn't glamorous, its entirely
text with gameplay true to the
original. You take turns with
COMPUTE AUGUST 1993
the computer, playing or dis-
carding cards from your
hand, trying to accumulate dis-
tance toward a goal of 1000
miles, Along the way you play
cards against the computer's
hand and try to inflict your op-
ponent with all sorts of calam-
ities, including flat tires and ac-
cidents. You see where atti-
tude can creep into the game.
According to comments
posted on Q-Link about this
game, some of its more ob-
scure rules aren't supported in
this version. I wouldn't know,
since I don't play the original
enough to remember any of
the more obscure rules! All I
know is that this little gem of a
game Is addicting.
The computer is a bland ad-
versary, of course. I miss the
scowl I used to get from my
wife when I would gleefully
siap down an accident card.
She doesn't play Mille Bornes
on our 128 much. She's too
busy playing Monopoly on the
IBM.
Maximum Overdrive
By Dan Komaromi.
QuantumLink filename: OVER-
DRIVE; uploaded by DigiDan.
I'm not sure what category to
put this piece of programming
genius into — it's certainly not
a game. But what the heck:
Here it is, and it's absolutely
my favorite 64 download of all
time. Like I just said, it's not a
game. It's not a utility either, re-
ally. It doesn't exactly keep
you glued to your monitor; in
fact, it works the best when
you aren't even around.
Let me explain. Maximum
Overdrive is the sneakiest buck-
et of surprises you'll ever
dump on your unsuspecting
64. When you first run it, you
are presented with a menu of
interesting-sounding options.
Once you make your choice,
your beloved Commodore com-
puter disappears and is re-
placed by nothing less than its
evil twin. Oh, it looks just fine —
same blue screen, same friend-
ly blinking cursor, same every-
thing. But, oh, what horrors
lurk v/ithin!
For example, when you en-
ter an innocent LOAD com-
mand, the computer might
snap back with LOAD IT YOUR-
SELF! With another setting,
your usually complacent 64 re-
acts to a keypress by snarling
that it's trying to sleep. It then
turns off its monitor.
There's a startlingly impres-
sive self-destruct mode which
really grabs your attention if
you have the volume cranked
up. There's even an option
which looks for all the world
like you've accidentally con-
nected with NORAD comput-
ers somewhere and have
launched a few missiles.
The author, who calls him-
self DigiDan on Q-Link, has
had his programs published in
several magazines, and his ex-
pertise shows in the slick inter-
face as well as in the nifty
screen tricks. He includes
some extra touches, such as
allowing you to disable the
Run/Stop key and type in your
own bits of nastiness for the In-
sult section. Koramoni em-
ploys some excellent raster in-
terrupt effects, a good dose of
SID chip sound magic, and an
oversized helping of clever-
ness to make your 64 go off its
electronic rocker.
The general idea :ts to set
up your computer with one of
these fake startup screens
when you are going to be
away from your keyboard.
Should some unsuspecting vic-
tims try to use it, they'll be left
wondering how they managed
to make the whole system go
kaflooie when they just typed
a simple command. I'm not
sure why I like this program so
much because I don't have
anyone to pull these tricks on,
but I get a bang out of watch-
ing them run.
I know. Get a life! TJ

Read a file
with BASIC'S iNPIJT#
statement and
chop any extra
Returns that
may cause a crash.
G-18 COMPUTE AUGUST
FILE-END TRIMIVIER
Last time, we learned that a
file that ends with more than
one return can cause trouble
when used with the BASIC IN-
■ PUT# statement, Now, let's
write a program to detect and
correct this problem.
A BASIC program will poke
the ML code into place.
Phase 1 then checks the file,
and phase 2 copies the file,
chopping any extra returns.
The detection phase uses a
brief ML program at $2200,
decimal 8704, The file is cor-
rected, if needed, by a longer
ML program at $2217, deci-
mal 8727. This is the code
we'll examine here.
File-copying programs
must deal with ST the status
word, found at address $90.
We must read the ST value
right after we reference a file
so that it won't be changed by
some other file activity.
Our program reads from
one file and writes to another.
We must check ST (for end-of-
file) after each read. We have
an input character to dispose
of, so we may need to write to
the output file before we act
on the end-of-file signal.
We'll test ST right after per-
forming an input and push the
test results to the stack. Later,
we'll act on those results.
Here's a second puzzle.
Our task is to remove extra re-
turn characters from the file
end. But, as we read the file,
we don't know if we're near the
end. We must not copy re-
turns until we know it's safe.
When we read a return char-
acter from the input stream,
we won't output it. We'll count
it, using location $2100 as a
counter. If we find more text,
we'll output the correct num-
ber of returns before continu-
ing. I'll comment on selected
parts of the program.
Initial code zeroes the count-
er at $221 7. We enter the main
read loop, and the input
1993
stream switches to logical file l .
We grab a character and
test the ST variable, pushing
the result to the stack with PHP.
2221 JSR $FFE4
LDY $90
PHP
We skip ahead if we didn't
get a return. Return needs spe-
cial work: We count it and
then check to see if we're at
the end of the input file. That
information is on the stack, re-
member? If we're not at end-
of-file, we keep reading.

This column
celebrates Its fittii
anniversary wlUi
some more great tips
sent In by readers.
G-20
HAPPY
ANNIVERSARY!
"Programmer's Page" is five
years old this issue! It made its
debut in the August 1988 edi-
tion of Gazette. I'd like to take
this opportunity to thank all of
my readers for your interest;
support; and, most important,
your great contributions. This
column, after all, is a forum for
your programming expertise.
To celebrate our anniversary,
I've assembled a few of the
best "Programmer's Page"
tips ever published.
Selective RESTORE
This bizarre tip — written by
yours truly — comes from the
very first "Programmer's
Page," This short routine re-
stores BASIC'S data pointer to
any line number, just like the
128's RESTORE command.
To use it, execute the follow-
ing instructions once within
your program.
BD 1« POKE 784,16a:P0KE 765,12
2;P0KE 786,0
PQ 20 DEF FN RS |N| =USH (N) +POS (
Then, add the following com-
mand to your program.
X=FN RS{/fne number)
In this case, line number is
the line number of the DATA
statement at which you want
your program to READ. In oth-
er words, RESTORE to this
line. The line number can be
a number, variable, or even
an expression such as
1000+1*10. If you want, you
can replace X with a variable.
Just be warned that the value
of the variable used will be
scrambled.
Be especially careful when
entering iine 20. A single typo
could cause the computer to
lock up when the program is
run. Note that there are no
spaces between the USR
COMPUTE AUGUST 1993
statement, plus sign, or PCS
statement.
To ensure accurate typing,
use The Automatic Proofread-
er; see "Typing Aids" else-
where in this issue. To heip fur-
ther, here's an English transla-
tion of how to enter those
weird characters found within
quotation marks in line 20:
space, Ctrl-A, Commodore-
U, space, Ctrl-T two Commo-
dore-English Pounds, Shift-F,
Back Arrow, Commodore-G,
Back Arrow, L, single quote,
and two Commodore-English
Pounds.
If you're looking for a chal-
lenge, try to figure how this tip
works — without looking in the
August 1988 Gazette.
MID$ Magic
Most programmers use BA-
SIC'S MIDS function on the
right side of an equal sign, as
in A$=fvllD$(B$,3,1). On the
128, however, MIDS can also
be used on the left side. For
example, if AS equals
123456789 and B$ equals
ABC, the instruction MIDS
(A$,4,1)=B$ sets A$ equal to
123A56789, while the instruc-
tion fVllDS(AS,4)=BS sets A$
equal to 123ABC789.
Using this technique, you
can stuff one character or a
group of characters into the
middle of another string with-
out juggling LEFTS and
RIGHTS functions. Credit for
this useful string-handling ad-
vice goes to Michael Ver-
diguel of Lawton, Oklahoma.
Unscrollable Lines
Here's a short machine lan-
guage subroutine from Sean
Ganess of Woodside, New
York, that protects the top two
lines from being scrolled off
the screen. You can still print
text to these lines and erase
them by clearing the screen,
but they are unaffected by
scrolling text. You might want
to use this feature to display
such things as your location
in an adventure game or to
show the disk drive status in
a utility program,

To use this program,, simply
GOSUB 3000 whenever you
want to protect the top two
screen lines. This subroutine
needs to be executed only
once when your program is
first run.
Missing Data
Neglecting to put numeric da-
ta between the commas in a
DATA statement is the same
as including the digit 0. For ex-
ample, check out the follow-
ing program.
10 FOR 1=1 TO 10: READ D:
PRINT D:NEXT
20 DATA ,„„„,,
Line 20 produces the same re-
sults as the following.
20 DATA 0,0,0,0,0,0,0,0,0,0
If you are reading string da-
ta—as in the command READ
DS — the missing data is inter-
preted as a null string. This
tip came courtesy of Doug
Ross of Merrickville, Ontario,
Canada.

BUCKS IN A POT
Let's get back to reviewing BA-
SIC statements, specifically
FOR-NEXT loops. Here's a
quick review. FOR-NEXT (or
FOR/TO/STEP/NEXT as ttie
Commodore 128 Program-
mer's Reference Guide calls
it) executes repetitive loops.
We've seen how each FOR-
NEXT loop requires seven sep-
arate and distinct elements
and Y\o^^ STEP can be less
than 1 , more than 1 , or a neg-
ative value. (Omitting STEP
yields a step size of -i-l .) Here
are some simple examples.
10 FOR J = 1 TO 4
20 PRINT J
30 NEXT
10 FOR J =
20 PRINT J
30 NEXT
5 TO 3.5 STEP .5
10 FOR J = 10 TO 1 STEP -2
20 PRINT J
30 NEXT
A very common use for
FOR-NEXT is to load arrays.
We've studied arrays in this
column before, but if you
don't understand or remem-
ber them, we'll get back to
them soon. For now, just
think of an array as a group of
pigeonholes that need num-
bers stuffed into them. The pi-
geonholes usually have
names such as A(1) or B(4).
Here's how to fill a small one-
dimensional array using a
FOR-NEXT loop.
10 FOR J = 1 TO 10
20 A{J) = 25
30 NEXT
This simple pigeonhole
stuffer will make each varia-
ble A(1) through A(10) equal
to 25. Here's how you can
make the variables equal the
counter as it's increased.
G-22
10 FOR J = 1 TO 10
COMPUTE AUGUST 1993
20 A(J) = J
30 NEXT
You can read DATA state-
ments and place them into
the arrays, too.
10 FOR J = 110 7
20 READ
30 A(J) = Q
40 NEXT
SO DATA12, 2, 52. 41.-3,3,5.
-7.34
After this program runs,
A(1) will be 12, A(5) will be
-3, and so on.
Let's take another look now
at nested FOR-NEXT loops.
Here's an example.
10 FOR A = 1 TO 3
20 FOR B = 3 TO 4
30 PRINT "A="A,"B="B
40 NEXT B
50 NEXT A
The A loop is the outer one,
and it loops a totai of three
times. The B loop is the inner
one, and it loops twice for
each value of A. The use of
the variable names after
NEXT is optional, but it can
help keep things straight.
Now, let's get to the meat
of this month's column. The
other day, a friend called to
ask for help with his third-
grade son Derek's homework.
The problem, as we under-
stood it, was to calculate how
many combinations of twen-
ties, tens, and fives could be
in a pot of $200. Naturally, I
don't need much inspiration
to write a BASIC program. So
I wrote one to solve the prob-
lem, and it just happened to
use nested FOR-NEXT loops.
Here it is.
10 PRINTCHRS(147)
20 INPUr'HQW MUCH IS IN THE
POT";P
30 TW=P^O
40 FORI=0 TO TW
50 R=P-I*20
60 TE=R/10
70 FORJ=0 TO TE
80 C=C+1
90 NEXTJ
100 NEXTI
110 PRINT:PRINT"THERE
ARE'C'COMBINATIONS."
Line 20 asks the user for a
pot value. Enter the number
only, not a dollar sign. Line 30
finds the maximum number of
twenties (TW) which can be in
the pot. Then we start a loop
in line 40 which counts up
from no twenties to TW.
Lines 50 and 60 calculate
the maximum number of tens
there can be in the pot for
any given number of twenties,
Our inner loop (J) begins at
line 70 and counts up from no
tens to the maximum number
of tens for each value of I, the
twenties counter.
Inside the inner FOR-NEXT
loop is another counter (C in
line 80) which simply incre-
ments every time the inner
loop is used. For each num-
ber of tens for a given num-
ber of twenties, there will be a
certain number of fives neces-
sary to arrive at the total pot.
Therefore, we've counted all
the possible combinations!
If there were ones in the
pot, you would need another
FOR-NEXT loop which would
increment (or decrement) the
fives while holding the twen-
ties and tens constant. The
number of combinations
would become staggering.
This seemed like a tough
problem for a third-grader to
solve. We discovered later
that the actual assignment was
to find just some of the possi-
ble combinations — not all of
them! Anyway, it was an inter-
esting problem and a good ex-
cuse to write a BASIC pro-
gram. By the way, there are
121 possible combinations of
twenties, tens, and fives in a
pot of $200. With larger pots,
watch the time it takes to cal-
culate the combinations grow
exponentially. o

IMPORTING GEOS
GRAPHICS
Two of my favorite subjects
are graphics and geoPublish,
and last month I tallied about
both. I described differences
between geoPaint's bitmap-
ped graphics and geoPub-
iish's object-based ones.
This fundamental differ-
ence between the two formats
is important for you to under-
stand, lest you find yourself
confused and frustrated.
Once you get the hang of ob-
ject-based graphics, though,
you'll love the freedom that
they give you to experiment
and to create.
Working with geoPublish,
you'll most likely want to use
clip art with your documents.
Most of this art will be in
bitmap format, which means
that it's stored as a fixed set of
dots laid out to form an image.
This graphics don't use the
same format as those created
by geoPublish itself, but that
doesn't mean that you can't
use them. You can import
these bitmaps very easily,
Each mode of geoPublish
has an import tool. In both
Page Graphics and Master
Page modes, the bitmap ap-
pears where you click the
cross hairs on the page.
Once imported, the bitmap is
an object on its own layer, just
like any other object on the
page. Remember, if you en-
large this image, you won't be
adding more dots to the im-
age; you'll only be making the
existing dots bigger, As a re-
sult, an enlarged bitmap
looks blocky and jaggy, Geo-
Publish offers a smoothing op-
tion which helps by rounding
off some of the sharp edges,
but this doesn't always make
it look better.
In Page Layout mode
things work a little differently.
You can still resize an image
and change its attributes, but
the way you move a bitmap on-
to your page is unique to this
mode. In Page Layout mode
you create rectangular areas
(regions) on the page in
which to place text or, in this
case, bitmaps. Before you can
import an image, you must de-
fine an area in which the im-
age will be located. This re-
gion can contain only the
graphic or text file you specify
for it. If you place a region on
top of another region, you
won't be able to see through
the one on top. And if you
place the region on top of a
text region, the text will adjust
around it.
This is very useful for mixing
text and graphics on a page.
You can create a large text re-
gion, then create graphics re-
gions on top where you want
the bitmaps to appear. The
text will flow around those re-
gions as pretty as you please.
In Page Graphics mode,
however, if you place a graph-
ic in the middle of a text area,
the two will just overlap. This
also can be a useful tech-
nique if you change the pat-
tern of the bitmap to gray in-
stead of black, allowing the
text to stand out. But if you
want text to flow around graph-
ics, you'll want to import those
graphics in Page Layout
mode.
Remember that I said that
the regions you create in
Page Layout mode are rectan-
gular. The text will flow around
that rectangular area, not
around the edges of the im-
age itself. There's no built-in
way to make text flow around
an irregular edge. You can sim-
ulate this effect by creating a
number of text regions, each
sized to hold a few lines of
text and each fitted to the edg-
es of the graphic Image. The
problem occurs if your graph-
ic was imported in Page Lay-
out mode. This mode won't let
you cross its straight region
edges with your text regions.
If you import the image in
Page Graphics mode it won't
be visible in Page Layout
mode at all, which means it'll
be next to impossible to fit a
text region next to it with any
precision. Probably the easi-
est way to simulate text flow-
ing around an irregular graph-
ic is to create text which has
a built-in flow created by press-
ing the Return key at the end
of the lines in strategic places,
then fitting the graphic to it in
Page Graphics mode.
There is one other way to
get graphics onto your geoPub-
lish page. You can first import
them into a geoWrite docu-
ment which you then import in-
to your geoPublish document.
The graphic gets imported as
well as the words. It even
keeps its formatting within
that text area (centered, for ex-
ample). This method works par-
ticularly well if you want the
graphics to be tied to the text,
such as in a fancy headline or
a letterhead. Of course, you're
stuck with geoWrite's rather lim-
ited photo scrap size.
Let's think bigger for a min-
ute. It can be a bit of a hassle
to import photo scraps when
they're limited to the size of the
geoPatnt window. There are
utility programs which will let
you clip photo scraps as large
as an entire page. One of the
best, called Scrap Can,
comes as a bonus on the geo-
Canvas disk from Creative Mi-
cro Designs. A shareware ex-
ample is Scrap It (Q-Link file-
name: SCRAP IT uploaded
by TerryVT). These utilities will
in effect let you convert an en-
tire geoPaint page into a geo-
Publish page, although the
whole thing is then a single
large object. You can also con-
vert a geoPublish page from a
series of layered objects into a
large bitmap (in other words,
convert it into a geoPaint docu-
ment) with the program Paint
Pages, which comes in the
GEOS 2.0 package. O

bags shifted
with more parts
than a small

G-24 COMPUTE AUGUST
MULTIMEDIA
ROAD WARRIOR
My name is Fred D'Ignazio,
but mosl peopie l<now me as
tlie Road Warrior. For the past
ten years, I've journeyed to
more ttian 100 sctiool districts
in Nortli America, Europe, and
Australia as a multimedia evan-
gelist — a Johnny Appleseed
of new technology.
My mission began in the
mid-1980s in a kindergarten
classroom in Cahaba
Heights, Alabama. I had con-
ceived a concept of class-
room learning known as the
multimedia sandbox. Children
and teachers in the sandbox-
es scavenged common items
from around their schools
such as a computer, a tape re-
corder, a record player, a tiny
musical keyboard, a VCR, a
TV, a camera, and so on, I
then taught them how to use
$5 Radio Shack cables to con-
nect these items into a chil-
dren's multimedia publishing
center,
The idea caught on like wild-
fire in the Jefferson County, Al-
abama, schools. Pretty soon
we had 13 multimedia sand-
box schools and almost 100
children, parents, and teach-
ers who were learning to as-
semble, troubleshoot, and op-
erate these scavenged multi-
media workstations.
In early 1986 I was invited
as a featured speaker to one
of the foremost national confer-
ences for computer-using ed-
ucators. To prepare for the na-
tional debut of the multimedia
sandbox, I asked the confer-
ence organizers for the basic
elements of a scavenged work-
station (a computer, VCR,
camcorder, and so on) along
with presentation devices
such as a video projector and
a speaker system for a room
full of hundreds of adults. I ar-
rived at the conference fully ex-
pecting all the equipment to
1993
be assembled for me. After all,
the Jefferson County kids and
teachers had mucked around
with this stuff for months.
Boy, was I surprised! None
of my stuff Vi/as ready. Techni-
cians were scratching their
heads and telling me that it
was impossible to plug a com-
puter's video-out jack into a
VCR and that it was not appro-
priate to use a common tape
recorder as an audio input de-
vice for a VCR. There were
none of the Radio Shack ca-
bles and adapters that I re-
quired to integrate the little de-
vices into a multimedia work-
station.
But 1 toughed it out. I reas-
sured everyone that such
things were being done every
day by five-, six-, and seven-
year-olds in Alabama. Then, I
rushed out of the hotel and ran
across town to a Radio Shack
and quickly purchased £25
worth of cables and adapters.
Back at the conference ho-
tel, I hurriedly plugged cables
to the equipment and comput-
er. A short time later, hun-
dreds of people arrived for the
demonstration of my multime-
dia sandbox. I turned on the
video projector. Uh-oh! The
bulb burnt out. I turned on the
large speaker that the hotel
had provided for my sound sys-
tem. No sound. No one could
hear or see my stuff.
I'd brought an hour's worth
of videotapes and computer
slides created by the Alabama
children on their scavenged
multimedia workstations.
They included multimedia sto-
ry problems formathciass;mul-
timedia book reports and biog-
raphies; and multimedia sci-
ence projects featuring animat-
ed iDlack holes, beating
hearts, and dancing skele-
tons. I also had a wonderful
presentation by a team of kin-
dergartners and sixth-graders
titled "What Is a Principal?"
I couldn't show any of it. I
was stunned. What had be-
come simple for us in my kin-
dergarten classroom in rural Al-
abama was impossible to dem-
onstrate in a world-class tech-
nology conference in one of
America's largest cities.
I survived that experience
by calling my audience to the
front of the room to see my
stuff on a little TV and comput-
er screen and to listen careful-
ly to the puny sounds coming
out of my portable speaker.
That's the day I first be-
came a multimedia Road War-
rior. 1 vowed that I would nev-
er be caught off guard again.
Since then, I've traveled
with all of my multimedia sup-
plies squashed into four dura-
ble Road Warrior bags. I carry
the two smaller ones on board
each plane and check the two
larger bags. If the two larger
bags don't show up at my des-
tination, i can do a "Multime-
dia Lite" presentation with the
cables and stuff from the two
carry-on bags. If I'm fortunate
and the airlines doesn't lose
the two bags that I've check-
ed, I can put on a whiz-bang
"Multimedia Classic" presenta-
tion full of rocket ships blast-
ing off, kindergartners' digital
videos, and New Age music
composed by deaf children.
So if you're in an airport in
the coming months, watch for
me. I'm the small bearded
man, rushing from one airport
gate to the next, carrying two
small duffel bags, trailing
green and red Radio Shack ca-
bles, and spilling stacks of CD-
ROMs and disks on the floor
behind me.
It's a dirty, sweaty job, but
some day, peopie will look at
their gleaming multimedia TVs
and remember the early days
of multimedia, back to the
days of spaghetti-like cables,
the multimedia boxes that nev-
er seemed to work together. If
you jog their memories, they
may even recall a little man
with a vision — the guy they
called the Road Warrior. □
PROGRAMS
32 SPRITES
By Bill Soudan
As far as games go, most 64 users are
aware that they normally are limited to hav-
ing eight sprites (or MOBs, Movable Ob-
ject Blocks) to manipulate. There are pro-
grams, hov/ever, that can double or even
triple the eight-sprite limit, but these pro-
grams often impose restrictions or
cause annoying flicker — making the ex-
tra sprites almost worthless.
Thirty-two Sprites lets you quadruple
the 64's sprite limit without losing any flex-
ibility while keeping flicker to the barest
minimum. Thirty-two Sprites can handle
up to 32 sprites at a time, and each
sprite can be placed anywhere on the
screen!
Thirty-two Sprites is a BASIC program
that lets you create a customized ma-
chine language routine for up to 32
sprites. To help avoid typing errors, en-
ter 32 Sprites with The Automatic Proof-
reader; see "Typing Aids" elsewhere in
this section. Be sure to save a copy of the
program before you run it.
Getting Started
Load and run 32 Sprites. After a short
pause, a main menu will come up.
This is where you can customize al-
most every aspect of 32 Sprites. To
change an item on the menu, type in
the number in front of the parameter
you want to change and press Return.
If the parameter can be turned on and
off, the program will first prompt you for
the desired setting. Next, the program
will ask you the new memory location.
You can enter the new location in ei-
ther hex (by preceding it with a dollar
sign) or in decimal. You may simply
press Return if you wish to leave the pro-
gram at its default location.
Menu Selections
The first item in the menu is Starting Ad-
dress. This simply specifies the mem-
ory location where the machine lan-
guage code for 32 Sprites will begin in
memory. The next eight menu items cor-
respond to the computer's sprite regis-
ters. Each of these can be turned on or
off, and each can also place the shad-
ow registers anywhere in memory.
Because there are only enough reg-
isters in the VIC chip for eight sprites,
32 Sprites must set aside a section of
memory to handle 32 sprites. The hex
and decimal addresses listed next to
each of the sprite parameters indicate
where in memory the shadow registers
of that particular parameter will start.
You can place these shadow regis-
ters anywhere in memory. For exam-
ple, the default Y position shadow reg-
isters start at 52992 (SCFOO). To
change sprite 1's Y position, simply
poi<e 52992 (SCFOO) with the desired Y
position. Each consecutive memory lo-
cation controls the next consecutive
sprite number. To change sprite 2's Y
position, poke 52993 (SCFOI) with the
desired number. This continues to loca-
tion 53023 ($CF1F), which controls
sprite 32's Y position.
Temp Page
The next menu item is Temp Page.
This is a workspace m memory 256
bytes long, required to sort the sprites
from the least Y position to the greatest
Y position. All 256 bytes are used, and
this area of memory should not be
used by any other program.
Order Table
Order Table is the next menu item.
This is a 32-byte area needed by 32
Sprites to hold the order of the sprites
after they are sorted.
Extra Y Table
Because 32 Sphtes uses interrupts to
function, changing a sprite's Y position
while the VIC chip is drawing will
cause that particular sprite to flicker
and possibly will cause other sprites to
flicker as well. The Extra Y Table is a
copy of the Y position shadow regis-
ters, and it is used by the interrupt rou-
tine to prevent flicker. Again, this 32-
byte area should not be used.
How Many Sprites?
The tast menu item lets you determine
the maximum number of movable ob-
ject blocks or sprites that you want to
use at one time. This number can be
changed to 16, 24, or 32. Note that
changing this register changes the
length of the shadow registers. If 32
Sprites is set to 16 sprites, only IB shad-
ow registers are needed. This should al-
ways be set to the maximum number
of sprites which you plan to use in
your program.
Generating 32 Sprites
After you've set the parameters for
your sprites, it's time to generate 32
Sprites, which is a machine language
routine. This is item 14 on the menu.
A minute or two after selecting this
option, the program wilt generate the
code and supply you with its starting
and ending addresses in both decimal
and hex and with information on how to
enable and disable 32 Sprites. The pro-
gram will ask you if you'd like to save
the ML routine to disk. Respond with /
or W
If you wish to save 32 Sprites to
disk, press Y and the program will
prompt you for a filename. Type in
your choice of a filename and hit Re-
turn. Make sure a disk is in the drive.
Be careful because the program
doesn't check for disk errors.
After the program is saved or after
pressing N at the save prompt, the pro-
gram will ask if you want to print an in-
formation sheet. The info sheet is sim-
ply a listing of the starting and ending
addresses of the ML routine; the SYS
addresses that enable and disable 32
Sprites; and a copy of the main menu
parameters, with the on/off status and
address. If you'd like a copy, turn on
your printer and press Y. Once the print-
out is completed or after hitting N, the
program will clear the screen and end.
The 32 Sprites machine language is
now in memory and ready to be used.
Your Own Programs
With 32 Sprites, you can now write
your own BASIC programs that contain
up to 32 sprites. Before calling the SYS
address to start 32 Sprites, your pro-
gram must clear out the shadow regis-
ters; otherwise, a screen full of gar-
bage sprites will appear on the screen
when 32 Sprites starts. You can do
this by poking Os into the shadow regis-
ters with something like the following.
100 FOR J=0 TO 31: POKE 52g92+J,0: NEXT
This line will set each sprite's Y position
to 0. Don't forget to do this to any oth-
er shadow registers which are being
used, too.
Once all registers have been
cleared and/or set up as desired, use
SYS and the starting address of the ma-
chine language program. Thirty-two
AUGUST 1993 COMPUTE G-25
PROGRAMS
sprites will enable raster interrupts,
clear out the temp page, and begin to
operate.
The best way to handle the shadow
registers is to define a variable at the
beginning of the program with the reg-
isters' location. Here's an example.
110 YP0S=5Z992: REM Y POSITION
SHADOWS
Then to change any given sprite's Y po-
sition, use the POKE command.
120 POKE YPOS+5,100: REM SPRITE 6'S
YPOS
Note that you subtract 1 from the
sprite's actual number. To change
sprite 32's Y position, you'd add 31 to
the YPOS. To change sprite 1 's Y po-
sition, you could use YPOS plus 0, or
simply YPOS.
The shadow registers of High X bit,
X expand, Multicolor, and Priority oper-
ate a bit differently. Each of these reg-
isters can be either off (by poking
them with a 0) or on (by poking them
with any number other than 0).
Each of the sprite parameters you
turned on before generating 32
Sprites with its BASIC generator can
be changed for each sprite by using
the corresponding shadow register.
Note that 32 Sprites doesn't change
any registers in the VIC chip which you
turned off before generating 32
Sprites.
For example, multicolor can still be
used even if you didn't turn it on from
32 Sprite's main menu. However, be-
cause you told 32 Sprites to leave the
register off, its shadow registers won't
work, and you won't be able to tell 32
Sprites v/hich sprites are multicolor and
which are not. But you can change the
actual register in the VIC chip.
For example, if you decide before-
hand that you are going to design all of
your sprites in multicolor mode, you
could turn off the multicolor shadow reg-
isters before generating and then tell
the VIC chip to display all sprites that
it draws in multicolor by using POKE
53276,255.
32 Sprites won't interfere with the mul-
ticolor register, and the VIC will display
all eight sprites as multicolor. In order
to display more sprites, 32 Sprites
G-26 COMPUTE AUGUST 1993
tricks the VIC into displaying either two,
three, or four sets of eight sprites on
the same screen. The VIC believes it's
displaying eight sprites in all, and it dis-
plays them in multicolor.
Thirty-two Sprites can handle up to
the maximum number of sprites you
set for it on the main menu. Every sin-
gle sprite can be displayed anywhere
on the screen. Displaying more than
eight sprites on a horizontal row could
cause flickering and some distortion.
Thirty-two Sprites operates at its best
when the sprites are spaced out along
the y-axis. Careful designing of game
screens will prevent too many sprites
on one row.
You may have noticed there wasn't
a shadow register which turns a sprite
on or off. To do this with 32 Sprites, sim-
ply set the corresponding sprite's Y po-
sition to 0. This tells 32 Sprites you
don't wish to have that sprite drawn.
Hints end Tips
Vl^hile greatly enhancing the 64's graph-
ics capabilities, 32 Sprites is a ma-
chine language routine which does
take up processor time. The more
sprites displayed on the screen and
the more parameters set to on, the slow-
er the computer runs. The best way to
conserve speed is to cut down on the
number of sprites. Of course, whenev-
er you need all 32 sprites, this will not
be possible.
The other way to increase the
speed of the computer is to turn off
any unneeded sprite parameters. In 32
Sprites' machine language routine, on-
ly the parameters turned on are updat-
ed by the program. The rest are left to
the VIC chip to handle. Although it
takes a minimal amount of time to copy
a value from a shadow register to the
corresponding VIC register, it becomes
noticeable when you multiply this time
by 32.
The parameters which bog down
the computer the most are the High X
bit, X expand. Multicolor, and Priohty.
Do without them whenever you can. Al-
though the High X bit cannot usually
be done without, Priority is rareiy used
and can usually be set to off.
The next way to conserve processor
time is to place the sprites nearer the
top of the screen. Thirty-two Sprites be-
gins at the top of the screen and search-
es down until it finds the number of
sprites for which it was set. By placing
the sprites closer to the top, 32
Sprites will have to do less searching
and use less processor time.
You may notice some distortion of
the tops and bottoms of the sprites
when you're using 32 of them. This is
because the computer may be too
slow to update the VIC registers as
fast as needed when the sprites are in
certain positions. The best way to
avoid this is to leave the top and bot-
tom row or two of the sprite definitions
blank.
Because 32 Sprites is a raster inter-
rupt, it does change the interrupt vec-
tor at $0314-$0315. Machine language
programmers can still use another inter-
rupt, as long as it doesn't use another
raster interrupt. Every Veo second, like
the normal timer interrupt, and after all
the sprites on the screen have been
drawn, 32 Sprites jumps to the normal
interrupt routine, usually located at
$EA31 , This JMP is located at the start-
ing address plus $61. It can easily be
changed to jump to your own interrupt
routine instead. Just remember to end
your interrupt with JMP $EA31.
Although 32 Sprites provides im-
proved sprite capability and flexibility,
it's not infallible. Placing the sprites in
certain positions can often cause flick-
er or cause some sprites to disappear.
The best way to prevent flicker is to de-
sign playing screens which space the
sprites out along the y-axis.
Since the VIC chip is actually limited
to eight sprites, 32 Sprites divides all of
the sprites into eight-sprite chunks and
displays each chunk as one group.
You still cannot display more than
eight sprites on a horizontal line be-
cause of the VIC chip's limitations. If
you decide to put more than eight on
one row, 32 Sprites will do its best to
display more than eight sprites per hor-
izontal line.
How It Works
Thirty-two Sprites works by use of the
VIC chip feature called raster inter-
rupts. The computer screen is redrawn
every Veo second. After one screen is
drawn but before the next one begins,
32 Sprites quickly sorts the sprites in or-
der from lowest Y position to highest Y
position. On the screen, that is from
the sprite closest to the top to the one
closest to the bottom.
The program then displays the top-
most eight sprites and tells the ViC
chip to let 32 Sprites know when these
sprites have been drawn. Once the
VIC chip alerts 32 Sprites, the screen
is only partially redrawn. The topmost
eight sprites have been drawn, but the
rest of the screen hasn't been drawn
yet. So 32 Sprites puts the next eight
sprites into the VIC's registers, and
they are drawn. This process repeats
for each series of eight sprites.
A Demonstration
To give you some idea of 32 Sprites's
power, try this demonstration program.
The demo consists of a BASIC pro-
gram and machine language sprite da-
ta. Before you can run the demo, how-
ever, you must generate 32 Spritess.
Load and run the main BASIC pro-
gram. Once the menu comes up, type
14 and hit Return, When the program
asl<s you if you want to save to disk, an-
swer /and type in 32 for the filename.
This is the name the demo searches
for when it runs. Don't print out the In-
formation sheet at this time.
To help avoid typing errors, enter
the demo with The Automatic Proofread-
er. Save the program, before you try to
run it.
Sprite data is written in machine lan-
guage. Enter it with MLX, our machine
language entry program. Again, see
"Typing Aids." When MLX prompts, re-
spond with the following addresses.
Starting address: C3A0
Ending address: CAFF
Since the demo automatically loads
this data, save it with the filename 32
DEMO.ML. Make sure that this file and
32 are all on the same disk as the de-
mo. Control the demonstration with a
joystick plugged into port 2.

MIDWAY COMMAND
By Michael Sedlezky
Midway Command is a two-player strat-
egy game for the 64. You and a friend as-
sume the roles of American and Japa-
nese naval commanders during World
Warn.
Experience the Battle of Midway as
each of you orders your powerful carrier
forces into battle with each other. Your flo-
tilla is made up of battleships, cruisers, de-
stroyers, and aircraft carriers. There are
14 vessels per side. Winning the game is
accomplished by sinking your enemy's
carrier. Your ships battle each other with
cannon shells.
Midway Command is written entirely in
machine language, but it loads and runs
like a BASIC program. To enter it, use
MLX, our machine language entry pro-
gram. See "Typing Aids" elsewhere in
this section. When MLX prompts, re-
spond with the following values.
Starting address: 0S01
Ending address: 1680
The game is played on a grid
that resembles a standard checker-
board. Each occupied square con-
tains a marker that indicates a
ship. The American marker is
black, and the Japanese marker is
white.
Use your joystick in port 2 to po-
sition the game's cursor to select a
square of your choice. As the cur-
sor moves over a square, a view of
the ship is displayed along with its
type and two scale bars.
Ship Strength
One scale represents the ship's
strength. This scale represents the
amount of damage the ship can with-
stand. As the scale decreases in
size, the ship is in danger of sink-
ing. Damage inflicted on any ship
cannot be repaired.
Ship Firepower
The firepower scale represents the
amount of damage the ship's guns
will inflict on an enemy vessel's
strength. This scale will increase if
this ship fires the blow that sinks an
enemy ship. As a ship gains expe-
rience, it becomes a deadlier fight-
ing vessel.
Playing the Gome
The game is played in turns. Each
player has the option either to
move or to attack. The American
commander starts first. You choose
one of your ships by selecting it
with the cursor and then pressing
the fire button. You then have the op-
tion either to move or to fight by
pressing a function key Follow on-
screen directions.
You finish a turn by selecting a tar-
get square. The cursor is a green
shade if the target square is within
legal boundaries. In order for you to
move onto a square, it must be un-
occupied and within range. The bor-
der flashes red if you attempt an il-
legal move.
Moving and Firing
All ships can move at least one square
in any direction. Destroyers can move
two.
To attack, you must select an enemy
ship that is within firing range. Each
ship has different ranges, and you can
fire in any direction. The carrier cannot
fire. A destroyer can fire a distance of
only one square. Cruisers can fire two
squares only; they cannot fire one
square. A battleship can fire one or
two squares. The battleship is your
strongest piece, followed by the cruis-
ers and then by destroyers. Protect
your carrier at all times.
Game Hints
Whenever possible, force the enemy to
move into your range of fire so you can
get first shot. Use your cruiser or bat-
tleship to finish off an enemy so you
can increase your stronger piece's fire-
power.
Fight cruisers with destroyers. Use
the destroyers' two-square advantage
to jump to an adjoining square where
the cruiser can't fire on you.
If your opponent takes a defensive
strategy, analyze the setup and probe
the weakest side with your destroyers.
Attack from different sides and try to
draw the ships out of position.

CHASE
By Jon Piltingsrud
You're at home, quietly studying with a
friend, when a fanfare of noise erupts
from your 64. It announces the arrival of
a message from aliens who have taken
control of your computer. The communi-
que informs you that the advanced race
has sent the two of you something impor-
tant: a game! Before you know it, you and
your friend are in deadly competition on
the game's playing field.
Chase is an arcade-style, two-player
game for the 64 that requires two joy-
sticks. The game consists of two pro-
grams: Chase, a BASIC loader; and
Chase ML, a machine language pro-
gram, To help avoid typing errors, enter
Chase with The Automatic Proofreader.
See "Typing Aids" elsewhere in this sec-
tion. Be sure to save a copy of the pro-
gram before you try to run it.
Chase ML is written in machine lan-
guage. Use MLX, our machine language
entry program, to enter it. When MLX
prompts, respond with the following start-
ing and ending addresses.
Starting address: 2795
Ending address: 3484
Be sure to save the ML program with
the filename CHASE ML on the same
disk as Chase. Chase automatically
loads this program when it runs and
searches for that filename.
G-34 COMPUTE AUGUST 1993
The Rules
When you run Chase, you'll see the
message from the aliens. After you've
read it, press any key, and you and
your opponent will be on the playing
field. One player operates the red disk
and the other the yellow one.
You'll see your weapons on the
field. They resemble footballs. Each
weapon is colored to match one of the
players. The idea simply is to pick up
your weapon and touch your oppo-
nent, thereby destroying him.
While the rules may be simple, exe-
cuting the game plan isn't. Your oppo-
nent will be trying to avoid you until he
is armed. As powerful as these weap-
ons are, they have a few quirks. You
can hold them for only a few seconds
before they fly from your grasp and
land on another part of the screen.
As you chase after your weapon,
you may reach your opponent's first. If
you touch your opponent's weapon, it
win jump to a random location on the
screen. To make the chase more inter-
esting, each field has a number of ob-
stacles scattered about it.
To quit the game and see a tally of
each player's kills, press the Q key.
From the score screen, press either of
the joystick fire buttons to resume.

MEMORY MONITOR
By Kenneth R. Warrick
Several weeks ago, I was in a room filled
with more than 200 people, demonstrat-
ing a program that did a lot of string build-
ing. After a while, the program came to a
screeching halt by the inevitable gar-
bage collection process.
For more that a minute, I had all these
people cooling their heels while my trusty
64 did its housekeeping. I thought to my-
self how helpful it might be to keep a run-
ning check on the amount of string stor-
age space still available.
Of course, this number is what we are
looking for when we execute the BASIC
FRE command. But since FRE performs
garbage collection first, it doesn't tell us
how much space has been taken up by
obsolete string fragments. An onscreen
monitor that would keep track of space
available would be just what the doctor
ordered!
That's what Memory Monitor for the 64
does. It's a machine language utility that
keeps track of the amount of free memo-
ry remaining and prints it in the upper
left corner of the screen.
Typing It In
Memory is a BASIC loader that creates
Memory Monitor when it runs and
saves the machine language program
to disk with the name Memory Monitor.
To help avoid typing errors, enter Mem-
ory with The Automatic Proofreader.
See "Typing Aids" elsewhere in this sec-
tion. Be sure to save a copy of the pro-
gram before you try to run it.
Before I get into the program itself,
here's a little of the process that went
into its creation.
Sparked by the creative muse, I
thumbed through my copy of Mapping
ttie Commodore 64 and 64C to find the
location of the pointers at the begin-
ning and end of RAM that's available
for string storage. The end of the BA-
SIC array storage area (+1) marks the
first byte of the string storage area.
This address is stored at 49-50 ($31-
$32). Creating numerical variables
tai<es up memory, moving this number
upward and reducing the amount of
space left available for strings.
As strings are created, storage be-
gins at 40959 ($9FFF) and moves down-
ward toward the address found in $31-
$32. Thus the low end of currently
used string space marks the highest ad-
dress still available for string storage.
This address is kept at 51-52 ($33-
$34). By subtracting, we could find our
number.
We don't want our monitor to take
up any precious RAM, so we shouldn't
write a long BASIC routine to do the
job. A machine language routine
that's hidden away would be best.
Our routine should run unattended
in the background without having to be
called repeatedly from our BASIC pro-
gram. The Kernal has in its bag of
tricks a routine which every Veo second
interrupts whatever BASIC is doing to
increment the clock, control flashing of
the cursor, update whatever needs to
be on the screen, and check the key-
board buffer for any keypresses. By
wedging our routine in ahead of all
these housekeeping chores, our task
could be taken care of automatically.
Getting back to our little subtraction
problem, subtracting the address
found at $3l-S32 from the address
found at $33-S34 obtains our number
in the form of two bytes in the mathe-
matical formal of base 256, How do we
convert this to decimal format that hu-
mans can understand? Programmers fa-
miliar with Kernal routines will recall the
routine LiNPRT found at 48589
($BDCD) which is normally used to con-
vert the two-byte BASIC line numbers
to decimal and print their ASCII repre-
sentation to the current output device.
That should take care of this project in
short order.
Wrong! The interrupt routine has a
strict time schedule that will only allow
us to wedge in a fairly short routine. An-
ything longer will crash! That is just
what LINPRT is — too long. Back to the
drawing board!
By writing an efficient routine that util-
izes a large (2048 byte) lookup table,
we can meet the time schedule.
Those of us who hate mile-long lists of
DATA statements will like how short our
loader is. Our lookup table is created
for us by some fancy mathematics in
lines 30-60.
The program searches the first part
of our lookup table for the screen
POKE codes (which for the digits 0-9
are the same as their ASCII codes) for
multiples of 256 (represented by the
high byte obtained from our subtrac-
tion) in decimal format. The results are
parked in a five-byte holding area at
$C800-$C804.
The second part of the lookup table
has the values of 0-256 (represented
by the low byte) to be added into our
five bytes, Later we correct for any of
these sums that exceed 9 and make ap-
propriate carries. Then, poke to the
screen, color it white, and exit to the nor-
mal interrupt routine.
After reading the code for the work-
ing routine from DATA statements and
poking it into place, our loader creates
the lookup table. It then saves the en-
tire bundle to disk with the filename
MEMORY MONITOR by calling the Ker-
nal routine SAVE at 65496,
Once Memory Monitor is on your
work disk, you can load it with the ,8,1
extension and run it with SYS 51205.

PROGRAMS
You can also load and run the routine
from within a BASIC program with the
following line.
10 IF J=0 THEN J=1: LOAD "MEMORY
MONIT0R",8,1 20 SYS 51205
The manipulation of J prevents endless
loop recycling since a LOAD com-
mand from program mode automatical-
ly executes a GOTO the first program
line. While this may be done easily at
the beginning of a BASIC program, lo-
cating it anywhere else would require
a first line of IF J=1 THEN XXX, with
XXX the line with the SYS command.
Here's an easier one-liner that may
be located anywhere in your program.
10 POKE 780,0: 0PEN8,B,8,1, "MEMORY
MONITOR": SYS 65493: CLOSE 8;
SYS 51205
To turn off Memory Monitor and re-
turn to guessing how much memory is
left, enter SYS 51326.

CUBIC
By Stephen A. Bakke
Cubic is a logic puzzle for the 64. it resem-
bles a brightly colored cube whose six
sides can be twisted to mix up the colors.
When the puzzle starts, the colors are
mixed randomly. The object of the puz-
zle is to maneuver the colored pieces so
that each side consists of but one of the
six colors.
Presenting six sides of a cube on-
screen at one time can be a problem, To
get around this difficulty, Cubic unfolds
the cube and displays the sides next to
one another on the screen.
Cubic is written in machine language.
To enter it, use MLX, our machine lan-
guage entry program. See "Typing
Aids" elsewhere in this section. When
MLX prompts, respond to the following
starting and ending addresses.
Starting address: 0801
Ending address: 0EE8
Be sure to save a copy of the program
before exiting MLX. Although Cubic is
written in machine language, it loads
and runs like a BASIC program. Oper-
ator input is controlled exclusively by a
joystick plugged into port 2.
Getting Started
The top screen line is Cubic's status
line. It displays the program name, num-
ber of turns taken, and the best score
achieved. Below it are six squares
that represent the sides of a cube.
Each square consists of 16 smaller
squares of various colors arranged in
four columns by four rows.
To solve the puzzle, swap rows and
columns of squares between the sides
of the cube until all squares within
each of the six sides contain a single
color. Columns run up and down and
are numbered 1 on the left through 4
on the right. Rows extend left and
right and are numbered 1 on the top
through 4 on the bottom.
The bottom screen line is used for op-
erator input. Four inputs are required to
exchange a row or column between
two sides of the cube. Push the joys-
tick left or right to highlight f?ow for row
or Co/ for column. Press the fire button
to enter your selection.
The next entry determines the row or
column. Push the joystick left or right to
change the row or column number.
Press the fire button when the desired
number is displayed.
Then select the cube number from
which the swap is desired and press
the fire button. Next, select the cube
number to which the swap is desired
and press the fire button again. The
swap will occur, the number of turns
will be incremented, and the bottom
line will clear in preparation for the
next move.
The puzzle is solved when each
cube contains only squares of the
same color. The screen will remain un-
changed while the border cycles
through various colors until you press
the fire button. After you press the but-
ton, the best score will be set, the num-
ber of turns will be reset, and the six
sides will be scrambled in preparation
for another game.

AUGUST 1993 COMPUTE G-39
AUTOMATIC PROOFREADER
The Automatic Proofreader helps you
type in program listings for tfie 128 and
64 and prevents nearly every kind of
typing mistake.
Type in Proofreader exactly as list-
ed. Because the program can't check
itself, be sure to enter each line care-
fully to avoid typographical errors or oth-
er mistakes. Don't omit any lines, even
if they contain unusual commands. Af-
ter you've finished, save a copy of the
program before running it,
Next, type RUN and press Return. Af-
ter the program displays the message
Proofreader Active, you're ready to
type in a BASIC program.
Every time you finish typing a line
and press Return, Proofreader displays
a two-letter checksum in the upper left
corner of the screen. Compare this re-
sult with the two-letter checksum print-
ed to the left of the line in the program
listing. If the letters match, the line prob-
ably was typed correctly. If not, check
tor your mistake and correct the line. Al-
so, be sure not to skip any lines.
Proofreader ignores spaces not en-
closed in quotation marks, so you can
omit or add spaces between keywords
and stili see a matching checksum.
Spaces inside quotes are almost al-
w/ays significant, so the program pays
attention to them.
Proofreader does not accept key-
word abbreviations {for example, ? in-
stead of PRINT). If you use abbrevi-
ations, you can still check the line by
listing it, moving the cursor back to the
line, and pressing Return.
If you're using Proofreader on the
128, do not perform any GRAPHIC com-
mands while Proofreader is active.
When you perform a command like
GRAPHIC 1, the computer moves eve-
rything at the start of BASIC program
space — including the Proofreader — to
another memory area, causing Proof-
reader to crash. The same thing hap-
pens if you run any program with a
GRAPHIC command while Proofreader
is in memory.
Though Proofreader doesn't interfere
with other BASIC operations, it's a
good idea to disable it before running
another program. To disable it, turn the
computer off and then on. A gentler
method is to SYS to the computer's
built-in reset routine (65341 for the 128,
64738 for the 64).

AST 4/33S
MODEL 123B
The Cold War may have end-
ed, but that doesn't mean
they don't build battleships
anymore.
The AST 4/33s model
123B 486SX computer sys-
tem is a welcome change
from the recent spate of ev-
er-cheaper, ever-more-short-
cuts-taken, no-name sys-
tems filling the pages of mail-
order catalogs. At $1,895
suggested retail with a
street price of around
$1,700, the system is com-
petitively priced and offers
more features than average.
AST is a well-established
American company. The
company's Six Pack memo-
ry and clock enhancement
board was one of the few via-
ble ways to make the origi-
nal IBM PC (the XT) truly us-
able in the early 1980s. In
the years since, AST has en-
joyed a reputation for build-
ing solid, reliable systems.
Of course, you may not
have the room to dock a bat-
tleship on your desk. The
one real drawback to the
123B is its larger-than-stan-
dard size; 15'A x 6'A x
16'/2 inches. The advantag-
es of the unit could lead you
to consider digging a larger
harbor, though.
There are good reasons
for the 123B's bulk. The com-
puter gives you four fuil-
sized expansion slots, as
well as two 5^/i-inch and
two 3y2-inch drive bays — all
surrounded by a solid metal
case. You have all sorts of
room if you want to add ad-
ditional drives, internal mo-
dems, and cruise missiles.
Whatever.
Installation's simple. Plug
the monitor into the back of
the computer (the connector
will only fit one place), at-
tach the mouse and key-
board, then connect the pow-
er cords to the monitor and
computer. Turn them on.
That's it. Both DOS and Win-
dows are preinstalled on the
hard disk, and the AUTOEX-
EC.BAT file is programmed
so that Windows comes up
ready to use,
It may not look like it's
bine that with the quickness
of a 486SX-33, and you'll
find, as I did, that the sys-
tem has very satisfactory
throughput. Such Windows
applications as CorelDRAW!
and PageMaker — heavy sys-
tem resource users — show
nice zip. I was especially
pleased with the quickness
II may be built like a battleship, but the AST 4/33s model 123B 486SX

built for speed, but the
123B is fast and powerful.
The one I tried came with a
120MB hard drive, 4MB of
RAM, and a Super VGA dis-
play. The amount of RAM is
easily upgradable. The only
blip in an otherwise beauti-
ful design is that while the
SIMM outlets — where the ad-
ditional memory chips get in-
stalled — are convenient, the
sockets for adding video
RAM can only be reached
by removing the power sup-
ply temporarily. This, at
least, is a simple task, and
the rest of the system's con-
veniences make up for this
minor inconvenience.
The documentation is ex-
cellent, with good illustra-
tions of the procedures to fol-
low for the various types of
upgrades.
Some of the 123B's
speed comes from a large
256K memory cache, cou-
pled with a very fast Quan-
tum 120MB hard disk. Com-
of display updates for Co-
relDRAW! figures that had a
lot of fountain fills.
Hardware settings can
easily be switched through
the BIOS setup routine — no
need to take the case off
and look for DIP switches. I
found in my tests that the
computer is above average
in disk- and processor-relat-
ed tasks, compared to ma-
chines in a similar price
range.
We all know that comput-
er technology changes rap-
idly. The 1238 solves that
problem by offering an easy
upgrade path. Currently —
for about $350 to $700— it's
possible to increase the per-
formance of the 123B (and,
in fact, all of AST's Bravo se-
ries) by adding a clock-dou-
bler chip (DX2) and bring-
ing its speed up to 66 MHz,
Upgrading the processor
is a relatively simple opera-
tion. Just flip up the zero in-
sertion force lever on the
CPU daughter board, and
the old chip jumps right out.
insert the new chip, and the
upgrade's done. This fea-
ture and the 123B's overall
solidity will let you keep the
machine current with technol-
ogy for years to come, thus
making it a better invest-
ment than computers that
are harder to upgrade.
Yes, the 123B /s built like
a battleship (maybe that's
what the B really stands for),
but it's a fast, easily upgrada-
ble, and solidly reliable behe-
moth. 1 like it a lot.

MICROSOFT
MOUSE
It's no small thing to rede-
sign an input device, espe-
cially one with more than 60
million users worldwide. Yet
that's precisely what Micro-
soft has done with its new
mouse. In doing so, the
mouse design team ad-
dressed many questions
that may not have occurred
to users, and added fea-
tures which, in retrospect,
are natural and quickly be-
come indispensable.
First things first: The new
mouse looks different- For
one thing, it's a bit larger
and longer than its predeces-
sor. More importantly, it has
a shape. Gone is the famil-
iar bar-of-soap design, re-
placed by a device with a
graceful curve along its left
side. Microsoft's mouse re-
mains a two-button device,
although the buttons are larg-
er than on the classic
mouse,
At first glance, the new
shape may seem off-put-
ting. My initial reaction was

that the mouse was too large, that I
would have to retrain my hand after
years of using a classic mouse. The re-

ly. None of this should be too surpris-
ing: The curve — indeed, every aspect
of the device — is the result of intensive
research into hand anatomy, postures,
and ergonomics. Believe me, fvlicrosoft
knows hands!
Hands of all types, actually. Despite
the curve's location on the left side of
the mouse, the device is designed to
work well for either right- or left-hand-
ed users. Its size may make the
mouse a bit difficult for small children,
but it should be fine for teenagers on
up.
Other hardware features worth not-
ing include a new, heavier cable, one
that's less likely to kink. The center of
gravity and the balance for the mouse
are noticeably improved, and the track-
ing ball rolls more smoothly.
As important as the hardware is the
software, and it's here that the mouse
shines most brightly, f^^lany of the driv-
er innovations are not only common
sense, but also most welcome. A
good example is the new "snap-to" fea-
ture, which automatically directs the cur-
sor to the screen's default button.
Perhaps my favorite feature is the
screen wrap. At last! Now, when you
move the cursor off one side of the
screen, it appears on the opposite
side. A magnifier enables you to en-
large sections of the screen for closer
examination, while another feature relo-
cates the cursor at the center of the
screen should it get iost.
After you get over the initial surprise
of the mouse's new shape, you can
see how sensible — even conservative —
most of fvlicrosoft's decisions are. Yet
it's tough to see what's been left out,
unless it would be a completely wire-
less version. (It would be nice, upon
reflection, to have the mouse available
in more colors than Microsoft white,
but that's less a destgn than a market-
ing criterion.) The mouse will, after the
keyboard, remain the most important
interface device for some time to
come, and there's little doubt in my
mind that ivlicrosoft's new mouse rep-
resents an evolution, and a worthwhile
evolution, in this device's usefulness
and practicality.

MANAGEPRO
Make no mistake: ManagePro is a tool
for managers intent on managing peo-
ple and information, and it places a pre-
mium on making that information avail-
able in a number of formats. Beyond
the usual spreadsheet capabilities, it
lets you access information about
goals and the personnel in charge of
meeting them in a variety of configura-
tions: according to time lines, company-
wide performance objectives, organiz-
ational charts, immediate action lists —
even individual employee personnel
files.
This Is software that not only lets you
track your people and your goals but
takes pains to coach managers about
their responsibilities, too. As it says in
the tutorial, the creators of fvlanage-
Pro believe there are four key steps in
managing people toward collective
goals: set Ihe goals clearly; monitor pro-
gress; give feedback and coaching;
and evaluate, recognize, and reward
everyone's contributions toward the
goals.
f^/lanagePro is written with that philos-
ophy in mind. There's a people-status
board that prompts managers to
check on employee progress and offer
feedback. There's an Advice feature
built in that lets you access basic how-
to people management tips as you
pull people along toward your goals.
(Ironically, though, the advice is so ru-
dimentary that you may wonder how
useful it will be to managers who work
for companies sophisticated enough to
make optima! use of the software.) To
top it al! off, the creators of ManagePro
go so far as to include a short pep-
talk book. Managing People: Your Com-
petitive Edge in the '90s.
In terms of architecture, the software
is divided into two main headings:
90 COMPUTE AUGUST 1993
Goals and People. The Goals side fea-
tures a goal planner that elaborates on
companywide objectives and spells
out responsibility for meeting them, a
goal-status board that offers big-pic-
ture tracking at a glance, and a time-
line feature that lets you monitor target
dates for making it all happen. The Peo-
ple side consists of a status board
that offers color-coded prompts to
make sure you're evaluating and com-
municating with employees, a perform-
ance data file that lets you compile
performance appraisals, and a planner
that connects the dots between people
and objectives,
ManagePro is commonsensical; it's
a breeze to install and use. The learn-
ing curve doesn't seem prohibitively
steep, thanks in part to the excellent tu-
torial built into the software. But you
may be a while fathoming its many pow-
ers. The makers recommend half an
hour on the tutorial, but 1 lingered a lit-
tle longer to learn my way around the
extensive features, and I was glad I
did. You may not need ail that Manage-
Pro can do, but you needn't be
scared away — even if it has more pow-
er than you need right now.

in Br0derbund's series of interactive
CD-ROM storybooks called Living
Books. It brings Marc Brown's chil-
dren's book to the computer screen
with musical accompaniment, interest-
ing animated effects, and a voice to
tell the story. In it, you'll find the same
storyteller theme, lustrous high-reso-
lution graphics, onscreen play, and mul-
tilingual narration found in Brgder-
bund's original Living Book, Grandma
'n Me.
But unlike Grandma 'n Me, which
was rated for children ages 3-8,
Arthur is for somewhat more advanced
readers, ages 6-10. Like Grandma,
Arthur's tale can be told in English or
Spanish. Language is an option you se-
lect at the title screen, and from there
you can also click on Preview to get a
look at what's coming up in Br0der-
bund's next Living Book. Then you can
select whether you want to have the sto-
ry read to you or to play inside it.
If you have the story read, you see
the text from Brown's story highlighted
onscreen as it's read in Arthur's voice.
Children can read along, recognize the
words, and follow the animated action
as Arthur and his friends struggle
through Mr. Ratburn's third grade
class and prepare for the school's big
September Spell-a-thon.
All this (and more) happens when
you choose to play inside the story. Do-
ing so takes you to an interactive
mode which brings the elements on-
screen to life when you click on them.
Each screen is a page out of Brown's
book, and the animated illustrations fair-
ly duplicate those in the small bound
copy that Braderbund includes with
the software.
At every turn, the reader gets intro-
duced to subtle humor and imaginative
activities that will delight children and
charm adults. Arthur, like Grandma 'n
Me, teaches as it entertains and lets
children become players in the story-
books they read. These Living Booi<;s
delight at so many levels they'll make
you want to buy a CD-ROM player if
you don't already have one for your
home computer.

DOCTOR SCHUELER'S
HOME MEDICAL
ADVISOR
Healthcare reform comes in various
packages, and this one — Doctor Schuel-
er's Home Medical Advisor (Windows
3.1 version) — is lively with colorful graph-
ics, packed with information, and fun to
use.
The aim of Home Medical Advisor is
to nurture informed healthcare consum-
ers — a lofty goal that might help us to
carve away at a national cancer
called healthcare costs. It's produced
by Pixel Perfect and written by
Stephen J. Schueler, chairman of the
Department of Emergency Medicine at
Holmes Regional Medical Center in Mel-
bourne, Florida.
Home Medical Advisor is a handy re-
source that you don't have to be a
computer whiz to use. In fact, children
and adults alike enjoy Home Medical
Advisor at the St. Louis Science Cen-
ter, where the DOS version of this pop-
ular program is part of the Medical
Technology Gallery.
From abdominal pain to zinc oxide
poisoning, you can find information on
it in seven linked files: Symptom, Dis-

YOURWAY
"Manage your time and contacts," pro-
claims the tag line on the front of
YourWay, a sophisticated and elegant
variation on the old electronic-Rolodex
theme. When you first call up this easy-
to-install software, you see a card file
laid out in front of you, surrounded
along the edges by ali the icons you'd

j."^
T/ie complexities of YourWay pay off m its

expect; day, week, month, and task-
planner windows; cut-and-paste fea-
tures; and file-search features.
A built-in tutorial would've helped
me digest more quickly the range of op-
tions YourWay offers, maybe, but the
one in the manual does just fine. Don't
expect to get through it too quickly,
though. The simple stuff — like access-
ing and creating contact file cards,
and attaching notes to them via the no-
tepad accessory — is easy to learn and
pretty self-evident. But functions like ed-
iting and file searching get pronounced-
ly more complicated. Nothing over-
whelming, but you quickly get into ter-
ritory that's less intuitive and less graph-
ically friendly than the front end of
YourWay.
But once you've mastered the ins
and outs of card file maintenance and
use of the planner windows, YourWay
has a lot to offer. Want an alarm to no-
tify you of lunches, meetings, or any oth-
er planned events? Easy. Worried
about keeping your contact information
organized? YourWay cross-references
between the various planners and indi-
vidual card files, so that if you set up a
lunch with Tom Thomas on your daily
events planner, a note of it will also ap-
pear on the notepad attached to his
contact card. If you place a call to
Mary Watkins at 10;25 on October 8,
that'll be recorded too.
I found YourWay a little daunting at
first, but I soon figured out that that
was largely a graphic matter: Some of
the information-configuration screens ar-
en't immediately easy to grasp; they of-
fer options that'll send you scurrying to
the manual. Which is OK, because
once you've learned it, the scheme
92 COMPUTE AUGUST 1993
isn't particularly complicated.
The installation was easy, and so
far, the manual lias never let me
down — it's written in plain language
and features a good index. The only
drawback is that a piece of software
this high-powered has given me an in-
feriority complex about my list of con-
tacts. If I'm going to stretch the capa-
bilities of YourWay, I've got some se-
rious networking to do.

SIMUFE
SimLife, "The Genetic Playground." is
a new addition to Maxis's line of simu-
lations/games/toys, such as the pop-
ular SimCity, SimAnt, and SimWorld.
SimLife's silicon-based computer
world simulates many of the features of
our very own carbon-based life. You
build an ecosystem and fill it with life,
then test your world by changing ge-
netics and/or messing with the laws of
physics. Toss in a disaster — drought,
fire, flood, and so on — and see how
your world adapts.
To play you choose from six prede-
termined scenarios, such as exploring
how a desert evolves into a forest or
finding out what led to the extinction of
dinosaurs. There's also an experimen-
tal scenario, where anything you say
goes. (Flying llamas? No problem.) A to-
pographical map shows you the world
you're working on. Inside the map is a
small rectangle called the Edit Win-
dow. Scroll the Edit Window over the
map to find the section of the world
you want to look at up close. A Win-
dows-like menu system enables you to
easily call up world creation and con-
trol parameters, For instance, are any
of your plant and animal creations ex-
tinct, and if so, why? What can you do
to save those left that are in trouble?
Life is complex, and SimLife has a
lot of features, too— "more buttons
than all the bellies in China," the man-
ual declares. But, unlike life, SimLife
has an entertaining and gentle online
tutorial that introduces you to features
one at a time. Additionally, you can lim-
it or ignore many features so you won't
get overwhelmed. The manual also of-
fers a tutorial, reference, and education-
al bibliography. A lab book walks you
through putting an experiment togeth-
er and charting data.
SimLife gives you all sorts of interest-
ing options. If you want to see what hap-
pens to your world and its inhabitants
in an evolutionary sense, for exam-
ple, speed up the simulation, and
the years and generations will zip
by. If you're more interested in the
day-to-day events during the life cy-
cle of a plant or animal, all you do
is slow the simulation down. With
SimLife, you can do it all.

VIRUSCAN, CLEAN-UP,
VSHIELD
Every once in a while, a software com-
pany comes aiong that just seems to
do everything the right way and at the
right time. fvlcAfee Associates is one of
those companies. It has produced a
line of virus detection, removal, and ear-
ly-warning software that's head and
shoulders above the competition.
I've used one form of virus protec-
tion or another since I was first ex-
posed to computer viruses in college,
but I always seem to come back to the
McAfee products. The reasons are
quite simple: They work, they work
well, and they wor)< simply.
I have encountered several viruses
In my travels, what with being an avid
user of bulletin board systems (BBSs)
as well as a collector of shareware. Not
only has ViRUSCAN (the virus detec-
tor) never missed one, but CLEAN-UP
(the virus remover) has never failed to
remove even the boot-sector viruses.
The really Interesting thing about
McAfee products is that you probably
won't see them in your local computer
store. They're distributed througti the
shareware or user-supported concept
of distribulion, This means that you use
the software and, if you like it (that is,
it's a useful utility that you use with
some regularity), you pay the author
some registration fee. If you don't like
it, you just quit using it.
The other way you may get one of
the McAfee products is if it comes
with your computer. McAfee has
signed bundling contracts with some
computer manufacturers, such as
Austin and Leading Edge.
The programs come with very easy-
to-read documentation that fully ex-
plains all of the options available. I
feel that a specific word of warning is
warranted, though: When installing the
early-warning software VSHIELD, do so
after all networking and disk-caching
software and before any shells such as
Windows or fV!S-DOS Shell.

AMAZON: GUARDIANS
OF EDEN
Rising from his desk, your boss,
Wilbur Thornick. turns his back to you
as he gives you the bad news. The
expedition to the Annazon has been at-
tacked, he tells you, his hands
clasped behind his back, fingers twitch-
ing restlessly. Your brother is missing.
So begins Jason's (and your) adven-
ture to find his missing brother. Allen,
in Amazon: Guardians of Eden, What
separates this from other adventure
games is that the scene with Thornick
is a minlmovie, Amazon has traditional
adventure-type screens in which you di-
rect your adventurer to Look, Open,
Get, etc., combined with full-motion vid-
eo sequences and synchronized
speech that's anything but typical. As
one of my friends put it, "Cool!"
Naturally, there's a price to pay for
such coolness. Eight megabytes of
hard disk space is just the beginning.
You can play Amazon with the mini-
mum of hardware recommended, but
to really get all that this program offers,
you'll need a 386/33 computer, a
sound card, and an SVGA monitor sup-
porting 640 X 400 or 640 x 480 in 256
colors, with VESA compatibility
Amazon's story is patterned after the
campy old serials from the 1940s and
1950s, such as Flash Gordon, The
Lost City, and Rocketman, Our story
takes place in 1957, and you'll find vin-
tage cars and TVs — as well as a vin-
tage plot. The adventure is broken
down into chapters, each with its own
cliffhanger ending. To assist you on
your quest to find your brother in the
depths of the jungle, there's a player's
guidebook and a pop-up online help
window.
The online help consists of three lev-
els of clues, so you can make the
adventure as challenging as you can
handle. Begin with an intriguing, ob-
scure hint. If that's not enough, there

FLIGHT SIMULATOR
ADD-ONS
While several companies produce add-
on software for Microsoft's Flight Simu-
lator, none is quite as prolific as fyial-
lard. Recently, Mallard has released
many new pacl<ages, including Air Traf-
fic Controller (ATC) and Pilot's Power
Tools (PPT).
ATC (originally called Tracon) is an
impressive simulation that drops you in-
to the seat of an air traffic controller,
where it's up to you to get all aircraft in
your sector safely to their destinations.
To make the simulation as lifelike as
possible, ATC's display includes a re-
alistic-looking radar panel, complete
with a continually circling radar sweep
that updates critical data on the aircraft
in your sector. In addition, menus
across the top let you configure the sim-
ulation to your taste and skill.
As planes approach your sector,
their flight plans appear in a pending
queue to the right of the radar display.
How you handle a flight depends on its
flight pian. If a plane is just overflying
your area en route to another location,
you need do little more than keep it a
safe distance from other flights and
hand it off to the next controller. Take-
offs, on the other hand, must wait on
the ground until you release them.
Landings are the real challenge in
ATC. You must guide the plane into the
airport at the proper altitude and angle
for its final approach. As if this weren't dif-
ficult enough, you frequently have sev-
eral planes landing at the same airport,
one after another. To add to the realism,
digitized radio voices represent your com-

radar screen of a busy airport.
mands and the pilots' replies. ATC,
which includes both a DOS version and
a Windows version featuring much-im-
proved graphics, offers a gripping and
educational simulation.
If you've lost control of the dozens,
or even hundreds, of files comprising
the many scenery disks and other add-
on modules you use with Flight Simu-
lator, you might want to try Mallard's Pi-
lot's Power Tools. Using PPT, you can
use PKZIP to compress most files you
need for Flight Simulator into related ar-
chives, allowing you not only to save
huge amounts of disk space but also
to organize files into directories and re-
lated ZIP files. Most of the tools includ-
ed in PPT manipulate these com-
pressed files.
You might, for example, want to
have a directory containing all the
files, in ZIP format, from a specific scen-
ery package. Then, to use the scenery,
you simply select PPT's Copy Selected
2IPs & Run FS option and tell PPT the
file types you need for that current
Flight Simulator session, PPT does all
the dirty work, uncompressing the files
into your Flight Simulator Directory and
running Flight Simulator in the mode
you've selected. After the Flight Simu-
lator session, PPT deletes the files it
copied, and, if necessary, updates
your ZIP file with whatever files you
may have changed during the session.
Also included in this package is Mai-
lard's Flight Planner. There are also util-
ities to analyze and edit Aircraft & Scen-
ery Designer files, convert Flight Plan-
ner files into adventures for Mallard's Air-
craft & Adventure Factory (AAF), and
cross-reference various elements of an
AAF adventure, plus even more. Pilot's
Power Tools offers serious fliers pre-
cise and convenient control over their

PEACHTREE
ACCOUNTING FOR
WINDOWS 2.0
It's not often that an upgrade of an ex-
isting software product looks like an en-
tirely new package. Such is the case,
though, with Peachtree Accounting for
Windows 2.0. Peachtree built this new
version from the ground up. and it
shows.
Peachtree Accounting is targeted at
companies that employ up to 25 peo-
ple, with revenues of less than a million
dollars, though it's capable of handling
much larger businesses. It was de-
signed — like most other products in
the entry-level accounting genre — to
be used by people with little or no pri-
or accounting experience. The pro-
gram's new user interface will also
accomnnodate individuals with little or
no PC experience.
A simple, friendly tutorial walks the
new user through setting up the com-
pany's books (13 sample Charts of Ac-
counts are included), and an ongoing
checklist outlines the logical steps re-
quired to utilize features appropriate for
the user's business, "Smart Guides, "
which can be turned on or off, offer ex-
tra help at selected screens,
All of Peachtree Accounting's finan-
cial functions — Accounts Receivable/
Invoicing, Accounts Payable, Payroll, In-
ventory, Job/Project Tracking, Bank
Reconciliation, General Ledger, and Fi-
nancial Reporting — are fully integrated,
so data entered in one area automati-
cally updates any other affected areas.
And unlike with most other accounting
packages, you don't have to go
through complex month-end closing
procedures; the program automatical-
ly assigns transactions to the proper pe-
riod by reading the date.
Peachtree Accounting is also the
first accounting product to take fu,!l ad-
vantage of three powerful Windows
functions: Multiple Document Interface
(MDI), Object Linking and Embedding
(OLE), and Dynamic Data Exchange
(DDE). This means you can keep mul-
tiple windovk's open onscreen simulta-
neously, customize forms by inserting
graphic objects from other applica-
tions, and exchange data with other
programs.

nal version weren't available at this writ-

ing, the beta I saw looked
more intuitive and full fea-

uct I've seen. The program's
new look incorporates state-
of-the-art Windows conven-
tions: descriptive icons, real-

forms, and visual flow charts
that guide you through an
accounting process.
One of the most potential-

this upgrade is the Manager

els of your cash, collection,
and payables records, and
provides graphical analyses
and overviews of your com-
pany's financial status. More-
over, several new capabili-
ties have been added to
every major function of
Peachtree Accounting, en-
hancing the product's flexibil-

There's a lot of competi-

out is inevitable. When the
dust finally settles, however,
Peachtree Accounting will
likely still be around.

You're likely to find everything you need in the Data Stor 486-25SX.
a computer that combines speed with power.
cache, using fast static
RAM, is a part of the moth-
erboard and can be upgrad-
ed to 256K.
Because each machine
is configured based on the
needs of the specific pur-
chaser, there's no standard
configuration for the Data
Stor 486, other than the ba-
sic motherboard specifica-
tions: a 1 : 1 interleave IDE
hard/floppy disk drive control-
ler, a game port, a parallel
port, and two serial ports.
Input and output is han-
dled through AMI BIOS with
on-board CMOS for storing
the system configuration. An
ness of operation, I ran sev-
eral common programs on
the Data Stor 486 and a
Gateway 2000 386DX/33.
These included Windows ap-
plications such as MacDraft
and Hollywood — which are
heavily graphics and proc-
essing oriented — and DOS
applications such as Dance
of the Planets, Color Works,
and DeluxePaint lie, also
heavily processing oriented.
Dance of the Planets, in
fact, needs a math coproces-
sor to run at its best, yet it
moves along at an accepta-
ble rate on the Data Stor
486. In all cases, the Data
Stor 486 showed enough im-
provement over its 386 equiv-
alent to be the computer of
choice if both were availa-
ble and both were running
the same software.
To obtain data not biased
by my own interpretation, I al-
so ran the Norton Utilities
SYSINFO program and
looked at the benchmark
tests. What the benchmarks
told me was essentially
what I experienced — signifi-
cant speed in both file ac-
cess and processing. With
the IBM XT 8088 running at
4.77 MHz as a base value
of 1 in all indices, the Data
Stor 486 has a computing in-
dex (CPU speed) value of
54, a disk-speed index of
7.5, and an overall perform-
ance-index value of 38.5.
Compare this with the 386
values — which are, respec-
tively, 34.8, 7, and 25.5—
and you have a 50-percent
improvement.
My review unit also came
equipped with a Tseng
4000 local bus video board
offering Super VGA capabil-
ity, a high-resolution moni-
tor, a 207MB hard drive,
high-density 5'/i- and 3V?-
inch floppy drives, and a Lo-
gitech Series 14 mouse. All
of these were put through
their paces, and nothing
was found to be problema-
tic or wanting, Also available
for upgrades, but not includ-
ed with the review unit, are
fixed drives with capacities
of up to two gigabytes, a
Weitek math coprocessor,
and, of course, multiple vid-
eo displays and modems.
This computer is a menn-
ber of a family of Data Stor
486 ISA Series computers.
Depending on the flavor of
486 microprocessor you
choose, clock speeds may
be 25, 33. or 50 MHz. The
computer is fully IBM compat-
ible, attractive, well de-
signed, and easy to use.

REVIEWS
There are three buttons at the front of
the unit: a turbospeed button, a reset
button, and the power button. Although
a keyboard seems a mundane thing, it
can make all the difference when
you're using a computer, since it's the
peripheral you have most immediate
and lengthy contact with. The Data
Stor 101 keyboard is IBM standard
and has a terrific feel, with pleasing tac-
tile feedback and a solid click.
Case dimensions are 16-/2 x 1472 x
7 inches. The interior is well laid out
and is accessible with the removal of
seven screws.
With attributes ranging from a fast op-
erating speed to a keyboard with a
nice feel. I found plenty to like about
the Data Stor 486-25SX. It's a well-de-
signed, powerful machine.

DODOT 4.0
If you do a lot work with graphics, you
can surely benefit from a utility like Hal-
cyon Software's DoDot 4.0. DoDol is a
veritable Swiss Army knife of graphics
utilities, consisting of five separate pro-
grams: DoDot, DoConvert, DoThumb-
nail, DoSnap. and DoView. They per-
form a host of graphics functions.
The mam application, DoDot, allows
you to fine-tune and transform images.
One example might be converting col-
or images to gray scale or black-and-
white. It also lets you fax and scan im-
ages. DoConvert is a conversion utility
that supports conversion among 50 dif-
ferent graphics formats, including oth-
er platforms, such as Macintosh and
Sun. DoThumbnail lets you catalog
thunnbnails of images and search
terms into an easily navigated data-
base. DoSnap is a screen-capture util-
ity that lets you save captures in sev-
eral different formats. You can also
choose between sending the capture
to the Clipboard or to a graphics file.
DoView is a graphics-viewing utility
that allows you to view graphics by se-
lecting them from the Windows File Man-
ager or another file-management utility
Most impressive is the speed with
which each DoDot application per-
forms its allotted task. I converted sev-
eral 24-bit images to gray scale in half
the time it takes other similar utilities.
Conversion between file formats is al-
so quick, and DoConvert is a batch
converter, which means you can set it
up to convert several files and walk
away to do other tasl<s while the com-
puter works. I was disappointed, how-
ever, that you can perform only one
type of conversion — say. CGM to
PCX — per batch. Also, in my tests con-
verting EPS logos to CGM, DoConvert
dropped several letters, making the con-
versions useless. But most of the file
conversions worked fine.
DoDot performs just about every graphics
function you can think of
DoThumbnail is one of the most ver-
satile cataloging utilities I've ever
seen. It catalogs graphics not only on
your hard disk, but also on other sourc-
es, such as CD-ROMs and remova-
bles. When you access an image not re-
siding on your hard disk, DoThumbnail
tells you where to find it. Few of us
have big enough hard disks to allow sel-
dom-used graphics to occupy valuable
real estate. DoThumbnail is also faster
than CorelMOSAIC and some other cat-
aloging utilities.
Halcyon markets DoDot as the Com-
plete Graphics Toolbox. While this pro-
gram is both powerful and useful, it
lacks a few basic features, such as sim-
ple bitmap and vector editors, to be
complete. Also. DoDot itself misbe-
haved on my system, crashing often
and causing me to reboot. Halcyon
representatives say they haven't expe-
rienced this problem. Granted, my sys-
tem is more complex than many, but
other Windows programs run fine on it.
Those few minor drawbacks aside,
this is a great utility. In particular, Do-
Dot Is stronger at managing graphics
than some other utilities.

DOSUTILS
There comes a time in eve-
ry disk's life where it sudden-
ly begins to show problems,
at least every once in a
while. If you're lucky, you've
been keeping regular back-
ups and can safely reformat
your hard disk. If you ha-
ven't, you'll need a product
like DosUtils.
Sometimes just reformat-
ting won't do the trick.
Worse, the underused (and
properly so) DOS VERIFY
command doesn't do a very
good job of verifying disk
writes. What's more, DOS
gives the hard disk several
tries before it decides
there's a problem writing to.
or reading from, the disk.
That why, for example, you
might notice that a hard
disk or a floppy has slowed
down for no apparent rea-
son before errors are report-
ed. The disk may in fact
have been defective for a
while as DOS silently ig-
nored the problem, stoically
rereading or rewriting the
disk until it got the job
done.
DosUtils handles a wide
variety of tasks, it lets you re-
cover deleted files; acts as
a kind of super-CHKDSK
with its SCAN function;
reads, writes, and searches
the physical disk itself;
changes file attributes; tests
the disk controller; deter-
mines the speed of the disk
controller; finds defects on
the disk; and performs a
number of related feats. It
does these for all popular
hard disk types: ST506
MFfVl and RLL, ESDI and
IDE, and SCSI. It can low-
level initialize the ST506 and
ESDI, but not the IDE or
SCSI. A companion product
from Ontrack, Disk f\/lanag-
er, handles all drive types, in-
cluding IDE and SCSI,
I've laid on the alphabet
100 COMPUTE AUGUST 1993
soup for a reason: If you
have no idea what kind of
hard drive is in your comput-
er or why you'd want drive di-
agnostics or a better
CHKDSK, this product isn't
for you. On the other hand,
if you're the local power us-
er and find yourself doing
drive maintenance only be-
bag of tricks. Like
CHKDSK, it cruises the en-
tire disk in search of cross-
linked files, bad sectors,
and so on; but it roots deep-
er than CHKDSK. It's almost
as fast, however, and well
worth the very slight time pen-
alty. It took only a few sec-
onds longer than CHKDSK to
DosUtils is a powerful program for mainlalning hard drives, but it niiiy
be more powerful than casual users need.
cause everyone knows you
can do it, DosUtils might
just be the product you
need.
One very useful feature in
DosUtils' DiskLook utility is
the abiiity to back up critical
sections of the hard disk:
boot record, BIOS para-
meter block, file allocation ta-
ble, and root directory.
Since most disk problems
originate in those areas,
backing them up frequently
could well make or break
your efforts to recover data
when the disk starts to lose
its mind. DOS doesn't give
you any means of backing
up just these items, and the
BACKUP/RESTORE pro-
grams found in DOS are
best left untouched.
The SCAN utility will also
find its way into your daily
scan my 400MB of disk
space.
I appreciated DosUtil's
wide variety of command
line options. While switches
like Force XT mode or
Force DOS 4 rules may
sound like arcana, they're life-
savers when you're working
with a clone drive mecha-
nism that didn't quite copy
the programming interface
correctly or you're working
on a system that has ac-
quired more than one ver-
sion of DOS, (I once fixed a
machine that was sputtering
along with hidden system
files from DOS 2.11. a COIVI-
MAND.COM from DOS 3.3,
utilities from DOS 4.0, and
some leftover files from DOS
3.0.) Unfortunately the
Force DOS 4 rules option
isn't explained anywhere in
the manual, and I had to
call tech support to find out
what it does.
The documentation is
slim and missing a lot of tu-
torial information that might
sell more copies of DosUtils
to slightly less experienced
users. Many important func-
tions are given no explana-
tion at all — the programmer
and the person who wrote
the manual might have
known what Scans (Write-
read) all UN-USED data clus-
ters meanl. but I sure didn't.
There are other significant
problems with the manual.
There's no index, the print is
very small, and some useful
illustrations are marred by
their execution — they literal-
ly look as if they were done
on a typewriter, 1 still found
them quite useful, though, be-
cause they explain different
configurations of cables and
interface cards.
Is DosUtils worth your mon-
ey? If you know you need
It — if you need to revive
hard disks on the job — prob-
ably so. If your computer is
new, and you couldn't tell a
cylinder from a file if it
jumped out of your system
unit and bit you, then you
should save your money.

uales and, because of a computer er-
ror in his favor, receives his first assign-
ment: to captain ttie garbage scow Eu-
reka. Once on board, Roger faces an
insolent crew/ and a perplexing mys-
tery; Someone out tfiere wants to put
an end to StarCon.
As always full of wry and often irrel-
evant humor, this latest Space Quest
Space Quest V otfeis a neorealistic
approach akin to Star Trek, plus t]umor
installment goes further than any adven-
ture game has gone before, perhaps
with the exception of Star Trek, the
25th Anniversary Edition. The gags are
uniformly hilarious, the animated
shorts hysterical, and many of the prob-
lems you must solve seem ridiculous.
Those constitute the differences be-
tween Space Quest V and something
like Star Trek.
These two games hold in common a
revolutionary approach to puzzle-solv-
ing: neorealism. For instance, to open
a locked door, instead of employing a
bizarre gimmick, you must take a hole
punch found aboard the Eureka and
punch a specific pattern in a business
card.
The once-useless plastic card be-
comes a key that opens the door
You'll discover the necessary pattern
through extreme and unusual circum-
stances, but those conditions make
Space Quest V what it is: funny The log-
ic involved augments the slapstick and
elevates the game well beyond the mun-
dane horde of other adventures on the
market — many from Sierra itself.
Space Quest V utilizes Sierra's impec-
cable interface, allowing for nearly
transparent character actions. And,
like most other Sierra games, this one
features a nonstop and appropriate mu-
sical score. The graphics rank among
the best standard 256-color VGA work
done to date, while the animations rare-
ly seem to "take over" and leave you
with nothing to do but watch.
A number of Space Quest V puzzles
do require absurd timing — even saving
games won't alleviate your frustration
at Roger's 33rd death from pukoid spit-
tle or the hours of dead-end maze-crawl-
ing. These tedious arcade sequences
aside, anybody with a hankering to ex-
plore an alternate and spoof-filled uni-
verse must sign aboard the Eureka.

DISK MANAGER
Disk Manager saved my skin.
As a fairly competent programmer
and an acknowledged power user, I
tend to be pretty good at diagnosing
problems, weighing the values of vari-
ous solutions, and advising others on
both hardware and software matters.
So the other night when my system
hung and the IDE hard drive died
white I was racing for a deadline, I was
calm and collected enough to do what
few of my peers would do in that situ-
ation . , , I panicked. Some heretofore
unknown fvlr. Hyde leapt out from a
deep crevasse within my soul and
took over my consciousness. When I
av/oke, I realized I had done a FOR-
fvlAT C: on my hard drive. This isn't a
problem with most hard disks, but IDE
drives are a noteworthy exception. Do-
ing a low-level format is a no-no, ren-
dering the disk unusable.
Unless you have the astounding
Disk Manager, which saved my bacon
at 3:30 the next morning. Disk Manag-
er would be worth its price if only for
that feature because the IDE manual
mentions dispassionately that the only
recourse to a formatted IDE is to send
the dhve back to its manufacturer. Not
a good sign when it's 3:30 a.m. and
your deadline is at 7:30, But Disk Man-
ager does a lot more than just low-level-
format IDE drives. It will do the same
for any ST506, ESDI, IDE, or SCSI
drive. It will add a soft extension to

your BIOS to tweak drives with more
than 1024 cylinders, allow you to boot
from up to four operating systems,
repartition your disk, change thie inter-
leave and cluster sizes for each parti-
tion, and more. It even checks itself for
a virus infection on startup.
The documentation is much too
slim, relying almost solely on the online
help, which isn't the greatest. It has no
index and omits a lot of tutorial informa-
tion that, say, the Norton Utilities and
many similar programs offer. And
some of the items simply aren't cov-
ered at all. For example, the f\/lachine
Information option gathers certain ver-
sion data from the BIOS and DOS and
displays it without explanation.
The online help gives only vague in-
formation about that particular feature,
so I'll test you: Do you know what the
"Model byte" is? I didn't think so. (It's
a byte written into the BIOS by IBM; for
example, 255 means it's an original
PC, 254 designates an XT, and so on.}
Not only that, but the model byte is giv-
en in hexadecimai or base 16 notation,
so you're shown not the vaiue 255, but
FF, which is 255 in base 16.
Another problem is that the se-
quence of a particularly crucial set of
operations (Initialize Disk Surface, De-
fect Management, and Verify Disk Sur-
face) all listed on the same menu
wasn't given in the online heip and cer-
tainly not in the manual, so I had to
learn by time-consuming (and potential-
ly dangerous) trial and error. In other
words, you'd better be a power user
if you buy this product because the
documentation doesn't tal<;e your
hand and lead you through each step
the way Norton does. (To be fair. Disk
Manager's manual states that you're
expected to be an advanced DOS us-
er, and Disk Manager handles many
cases that Norton doesn't For exam-
ple, it can read the disk even without
a partition.)
But what Disk Manager does, it
does very well. It dispatched with the
low-level format of both my 212MB
hard drives quickly and efficiently. Dit-
to for the resuscitation of the old
Seagate hard disk on my seven-year-
old AT, which I'd planned to shoot and
bury in the backyard. It also deter-
mined correctly the disk types of sev-
eral other machines I tried, although it
lets you override parameters that you
determine to be incorrect.
Other miscellaneous features are
equally useful. For example, you can
write-protect whole sections of your
disk. While there's no password protec-
tion or encryption involved, this is
enough to prevent the casual or even
accidental tampering that can trash a
disk in seconds flat. Another fairly ad-
vanced feature is the ability to alter the
cluster size of your hard disk (in Eng-
lish, that means you can choose be-
tween speed and m:ore efficient use of
hard disk space).
Disk fvlanager is a great companion
to higher-level disk-recover tools like
Norton or PC Tools. If you're comforta-
ble enough around DOS and PC hard-
ware to know whether you need it,
Disk Manager does the job.

DOUBLERES 4
Get 600 dots per inch from a 300-dpi
HP LaserJet Series II or III! That's the
claim LPAC makes for its doubleRES
4. But the board does more than just im-
prove the resolution of Windows print-
ing; it also speeds up the process.
As a computing veteran with years
of experience, I've heard my share of
unfulfilled claims. As a result, I installed
doubleRES 4 with a bit of skepticism.
For me. installation meant loading
up the doubieRES 4 printer driver in
the usual manner and inserting the dou-
bleRES 4 board into the Optional 1/0
port of my LaserJet Series II printer.
Both of these tasks were relatively pain-
less. Completing the installation proc-
ess required changing the LaserJet's
configuration using the control panel
on the pnnter, (This was probably the
most difficult part of the process.)
With everything in place, I loaded a
20-page PageMaker 4.0 file, which in-
cluded a variety of line drawings and
used several Adobe fonts, as well as
about six screen captures. I was very
impressed with the increased printing
speed. The doubleRES 4 board in-
cludes an Intel i960 microprocessor
that does much of the work the comput-
er usually does, speeding up printing.
Once I finished my initial test, I be-
gan exploring the options available
with the doubleRES 4 printer driver.
These included the capabilities of se-
lecting either 300 or 600 dpi and choos-
ing halftone quality printing options of
53, 71, 85, or 106 lines per inch, an im-
portant feature if you print halftones
with a LaserJet,
I did have an opportunity to try
LPAC technical support. I use a Gate-
way 2000 486 with an ATI video card
that has an SVGA BIOS incompatible
with the doubleRES 4 printer driver.
LPAC did have an alternate driver that

I downloaded from its BBS.
The new driver solved a prob-
lem I was having printing
PageMaker files with run-
ning heads.
I also had a very simple-
to-explain problem printing
from Quattro Pro for Win-
dows: DoubleRES 4 simply
didn't v^ork with that pro-
gram! LPAC has discussed
the problem with Borland,
and both companies are
working on it. While I experi-
enced no problems serious
enough to scare me away
from doubleRES 4, you
should probably check to
be sure that it will work with
the software you need it for.
I did, however, successful-
ly use doubleRES 4 with all
the other programs I tried.
Printing multiple-page docu-
ments with doubleRES 4
was about five times faster
than with the standard driv-
er at 300 dpi printing from
Pagefvlaker, Word for Win-
dows, and WordPerfect for
Windows. The quality of the
printing was also improved,
as you would expect with
the increased resolution, al-
though the visual differenc-
es to the naked eye depend
on the font, style, and size
of ttie characters, especially
if you use Adobe fonts.
At $599, doubleRES 4
isn't a cheap add-on. But if
you need to upgrade your
HP LaserJet for increased
speed in Windows printing
and for 600-dpi resolution
{and still be able to print
DOS applications at 300
dpi) and if doubleRES 4 will
work smoothly with the appli-
cations you use, it's an excel-
lent alternative to buying a
new printer,

INTERNATIONAL
SPORTS
CHALLENGE
International Sports Chal-
lenge is another in a long
line of sports simulations
that attempt to reduce Olym-
pic-level competitions to joys-
tick tapping, twisting, and
v^iggling. In this omnibus con-
test you can compete in six
events, including marathon
running, diving, show jump-
ing (horses), swimming, cy-
cling, and shooting. Al-
though all events must
be played in a four-player
mode, your computer will
be thnlled to fill in for miss-
ing humans.
Unfortunately, Internation-
al Sports Challenge has little
to add to a leisure software
market already glutted with
superior titles. Fact is, this
game is one frustration after
another. The hassles begin
from the moment you try to in-
stall it onto your hard drive,
since the manual only in-
cludes instructions for run-
ning the game, not for install-
ing it. Luckily, typing the usu-
al install reads the needed in-
structions from the disk.
Installing the game is on-
ly half the battle, though,

seen in a sports game. In
many events tlie controls
are impossibly frustrating. In
[he diving competition, for ex-
ample, you must first get thie
diver into thie air by tapping
the joystick button when a cir-
clelike object expands to its
largest size. The circle ex-
pands so quickly however,
that the results boil down to
chance. Once your diver is
airborne, you must try to
line up two small balls on
the circle in order to exe-
cute the dive properly. For-
get watching your diver; if
you even glance away from
the control circle, your dive
will be as professional as a
belly flop.
The show-jumping event
is equally frustrating. Here,
you try to keep a horse on
course, making its jumps in
the assigned order. Al-
though the 3-D graphics are
OK, the horse is ridiculously
difficult to keep on track,
making the event more frus-
trating than it's worth. The
other events suffer equally (I

how the swimming event
worked), with the possible ex-
ception of the shooting
match, which is nothing
more than pointing and
shooting.
Finally, although the
game claims to support key-
board controls, there is no
documentation on how
those controls are implement-
ed. If you don't own a joy-
stick, plan to spend an hour
or two figuring out which
keys work with which
events — a nearly Impossible
task. Having a mouse won't
save you, either, since the
mouse works only intermit-
tently. You have to wonder
why they even bothered to in-
clude such meager mouse
support.
In summary, this game's
overly difficult controls, in-
complete and confusing man-
ual, and borderline graphics
and sound yield a leisure
product that's more work
than entertainment. I haven't
had this much fun since I
had a tooth pulled.

PUTT-PUTT JOINS
THE PARADE
If only we could relive our
childhoods! Instead of de-
ploying plastic army men or
posing Barbie dolls, we'd
play Putt-Putt Joins the Pa-
rade, an instructive charmer
chock full of bells and whis-
tles. Even if your problem-
solving and reading skills
don't require further develop-
ment, you owe it to your kid
ages 5-7 to bring home a
copy of this Humongous En-
tertainment product.
Putt-Putt, a cute little talk-
ing convertible, wants to
AUGUST 1993 COMPUTE 107

join the Cartown Pet Pa-
rade—quite the gala affair.
To participate, he must find
a pet, pay for a car wash,
and snag a balloon. Kids
take the wheel, using the
mouse to move Putt-Putt
around Cartown and acti-
vate secret Click-Points. In ur-
ban areas, kids have plenty
to do mowing yards, deliver-
ing groceries, and finding
their way around town. Out
on the open road, young-
sters will find that almost eve-
ry butterfly and flower ani-
mates when touched.
The problems Putt-Putt en-
counters won't stump an ea-
ger seven-year-old, but for
younger adventurers, figur-
ing ways around balky
cows, tacks in the street,
and busy intersections can
take some time. Successful-
ly solving such simple dilem-
mas results in rewards of
clever animated sequences
and clear digitized speech.
Putt-Putt also manages to
teach a few ethics lessons
without preachiness, For ex-
ample, Putt-Putt must locate
a missing child. Kids might
notice that the distraught
mother has a red balloon per-
fect for the parade, but the
game itself never mentions
rewards for noble actions—
until after they're performed.
Putt-Putt finds the child and
gets the balloon; kids just
might learn that valorous ac-
tion makes them feel better
about themselves. Besides,
doing the right thing is the on-
ly way to "win" the game.
Throughout, Putt-Putt and
friends talk to kids via quali-
ty digitized speech, offering
hints and encouragement.
Putt-Putt often reads words
on signs aloud so that kids
who can't read will be able
to make valuable word/ob-
ject associations.
Putt-Putt Joins the Parade
seems to borrow from the Lit-
tle Golden Books tradition of

charm with its anthropomor-
phic fire engines and automo-
biles, all of which smile jovi-
ally As mentioned, the whim-
sical backgrounds bristle
with Click-Points that trigger
amusing animations. The
manual, suitably titled The
Junior Adventurer's Hand-
book, consists of connect-
the-dots activities, pages to
color, and counting games,
to name just a few items.
The Junior Adventurer's
Toolkit completes the pack-
age with a Putt-Putt pencil,
sharpener, and box of cray-
ons — quite an assortment of
goodies sure to delight any
child.
So when the route cho-
sen calls for a gentle intro-
duction to computer interfac-
es and hours of light-heart-
ed play Putt-Putt looks like
the king of the road.

ROBOCOP 3D
Inspired by Orion Pictures'
science-fiction thriller, Ro-
boCop 3D unfolds in the
crime-infested streets of Old
Detroit, Here, the OOP Cor-
poration plans to construct
a new urban paradise. Delta
City, Numerous project de-
lays, however, threaten to
cost the company billions of
dollars unless it begins imme-
diate demolition of existing
buildings. lA/hen residents re-
fuse to leave their homes,
OCP sends armed Urban Re-
hab units to violently expel
all resisters. As RoboCop,
you turn renegade to help
the hapless citizens and
risk brutal retribution from
your greedy employer.
Gameplay consists of sep-
arate Arcade and fvlovie sec-
tions. Arcade mode offers
practice in five self-con-
tained action scenarios: Driv-
ing, Street Fights, Hostage
Rescue, Flying, and Hand-
to-Hand Combat. Whether
buzzing skyscrapers in sim-
ulated air combat, cruising
the lunatic fringe in your po-
ice cruiser, or busting
down doors to search build-
ings, you'll find that the de-
signers successfully evoke
the movie's gut-level sensa-
tion of danger and despair.
Both driving and flying— in
your experimental, combat-
ready gyropack — offer the
most visually dynamic ac-
tion, while the so-called ur-
ban pacification scenarios
prove utterly chilling. Only
hand-to-hand fighting fails
to excite, suffering from inad-
equate design and a clum-
sy control scheme.
Movie mode brings all
game elements together in
an open-ended adventure
spiced with cinematic-style
segues, subplots, and
seedy peripheral charac-
ters. The only rules are to fol-
low your prime directives:
Protect the innocent, uphold
the law, and serve the pub-
lic trust. Failure to do so
promptly ends your tour of
duty. Movie mode offers
enough variety, mystery,
and explosive action to en-
sure repeated play The big-
gest drawback, lack of a
save-game option, is sadly in-
dicative of the game's Euro-
pean design.
Graphics are rendered
with a pleasing blend of 256-
color bitmapped static
screens and fast-moving 3-
D polygons. Though the
game is considerably less de-
tailed than others of its
type, the first-person per-
spective and murky mono-
tones give this virtual world
its dark, jagged edge. Miss-
ing from the IBM version, un-
fortunately, are the spine-tin-
gling music and sound ef-
fects that enlivened the orig-
inal Amiga edition. The only
other major weakness is
strictly a matter of taste:
Thick with violence and
harsh ambiance, the game
could prove too grim.
Though decidedly not for
all tastes, RoboCop 3D deliv-
ers enough diverse challeng-
es and heavy atmosphere
to make it Ocean's best mov-
ie conversion yet.

DOS 6 FIRST-AID KIT
Clifton Karnes
MAKING THE BEST
OF DOS
Keep this handy
if you're installing
DOS 6. To find
out more about
DDubleSpace,
see "Windows
Workshop"
in the next issue.
120 COMPUTE
DOS 6 has caused quite a stir
recentiy, Judging from the
sales figures, it's clearly an up-
grade that a vast number of
[X)S users want, but some peo-
ple have reported problems,
especially with two modules:
DoubleSpace and MemMaker.
At COf\^PUTE, six editors
have installed DOS 6. All have
used Memf^aker, three have in-
stalled DoubleSpace, and
none have had any problems.
But since problems have been
reported, we advise caution.
Here's some advice on how to
save your system if you have
problems with DOS 6's Dou-
bleSpace or f^emMaker
First, IVlemMaker and Dou-
bleSpace are complex applica-
tions. If you're not familiar with
drive letters, paths, and mem-
ory addresses, don't install
these programs yourself. Get
a knowledgeable friend or co-
worker to help you.
The best defense is a re-
cent backup. So before you
do anything else, make a back-
up of your hard disk.
After you make the backup,
restore a few files to make
sure the backup is reliable.
This is extremely important, If
you need to restore later, you
want to know how to do it, and
you want to be sure your back-
up fs OK. Now, make a copy
on floppies of the software you
used to make the backup, put
the backup and the software
aside, and relax.
Let's tackle DoubleSpace
first. This utility compresses
and decompresses data on
the fly and, for all practical pur-
poses, nearly doubles the
size of most hard disks. It will
also slow down some 386 ma-
chines. We recommend at
least a 25-fvlH2 386SX with a
minimum of 2fvlB RAM (so you
can run SMARTDrive or anoth-
er disk cache) for installing
AUGUST 1993
DoubleSpace.
The first step is to install
DOS 6, if you haven't already
done so. Do this, and use
your system for a day or two
before you try installing Dou-
bleSpace or IVlemMaker. After
you and your system have ad-
justed to DOS 6, defragment
your hard disk.
Next, before you run Double-
Space, make sure you're also
running any software that nor-
mally creates virtual drives on
your system (CD-ROM or net-
work drives). This will help Dou-
bleSpace choose a drive letter
for its physical drive that won't
conflict with your usual environ-
ment. At COMPUTE, we've had
no problems running SMART-
Drive when installing Dou-
bleSpace, but it seems wise to
disable SMARTDrive for the
installation. Creating your Dou-
bleSpace volume may take sev-
eral hours, so be prepared.
Hopefully, everything will
go smoothly After the installa-
tion, you should be able to run
SMARTDrive again without
problems. If you do have prob-
lems, refer to the paragraph af-
ter the next.
Consider the next month a
DoubleSpace-testing period.
Back up your important files
every day and look for any
signs of trouble on your com-
pressed volume. At least
twice a day run DBLSPACE /
CHKDSK on the compressed
volume to test it for integrity If
you notice lost clusters, don't
panic. Try disabling SMART-
Drive's write-caching feature
with the line smartdrvi. where
/ is the letter of your physical
drive. (You can easily reena-
ble write caching with the line
smartdrv i+.)
If you do have severe prob-
lems with your DoubleSpace vo I-
ume, you can recover by fol-
lowing these steps: Install DOS
6 on a freshly formatted floppy
boot from the floppy reformat
your hard disk using the /s
switch, reinstall DOS 6 on your
hard disk, and restore your
backup. If you want to go back
to a previous version of DOS,
install that version on the format-
ted floppy and then on your
hard drive.
Now to MemMaker. First de-
termine whether you need to
run MemMaker at all. Do you
have DOS programs that run
out of memory? If you don't or
if you're using Windows al-
most exclusively, you proba-
bly don't need to load device
drivers and TSRs high.
If you do need to load
some programs into upper
memory, do it manually first.
Load the largest drivers first
and use the keywords DE-
VICEHIGH in CONFIG.SYS
and LOADHIGH in AUTOEX-
EC.BAT. To see how much
memory you've freed, use the
command MEM/C I MORE,
Expehment with the order
of the programs, too. This can
make a big difference. If you
can free enough memory this
way don't bother running Mem-
Maker. If you can't free
enough conventional memory
you'll want to run MemMaker,
but first, do this: Create a sub-
directory off your root direc-
tory called BACKUP and copy
your CONFIG.SYS and AU-
TOEXEC.BAT files into it. (If
you're running Windows, it's a
good idea to copy your
WIN.INI and SYSTEM.INI files
here, too.) If there's trouble
with MemMaker, you'll still
have your original copies.
Now, run MemMaker and fol-
low the onscreen instructions.
After MemMaker is finished,
check your memory situation
again. If MemMaker garnered
more conventional memory for
you, fine. If it didn't, go back
to your backups. If MemMaker
locks up when it's running, re-
boot your computer and by-
pass your CONFIG.SYS file by
pressing F5 when you see
Now starting MS-DOS ....
Next, copy your backups and
reboot your computer. a
