TROLLS

AND

TRIBULATIONS

If you're a strategy
action game fan, your col-
lection isn't complete with-
out Trolls and Tribulations.
It's already on our bestseller
list and bound to become
a classic

They're lurking in wait for
you - an entire underworld ful!
of sinister scavengers hidden
away in a maze of dark caverns,
rising waters and secret dun-
geons. Also tucked away in this
treacherous maae are glorious
treasures, thousands of
years old.

Disguised as a troll, you
have entered the under-
world to save the buried
treasures. You have 32
eerie chambers to ex-
plore at 7 levels, and
a wrong turn could
spell disaster.

As you get deeper and
deeper into the mysteries of the
caverns, you'll discover that your
wits are being tested more than
your reflexes. And woeful is the
troll who doesn't act quickly
when confronted by troll-
crunching cretins, flying buzzards
and sinister skulls.

Trolls and Tribulations,
this year's hottest hit from
Creative Software.

THE EDITOR'S

It seems that recently a few
readers have taken us to task for
printing our popular word pro-
cessing program in our maga-
zine COMPUTE!. We'd like to
address this issue to help clear
the air for this and future publi-
cation questions.

Our general policy has been
never to publish the same mate-
rial in compute! and the
CAZETTE. Our willingness to
make an exception to this policy
has been in those cases where
we feel we are able to deliver
software of such importance to
our readers that we think the
duplication is justified. Such is
the case with "Turbo Tape" and
"TurboDisk," two articles and
programs that will be appearing
in the July issue of the GAZETTE.
These are breakthrough-quality
programs. They appeared first in
COMPUTE!, but are of such im-
portance that we feel they
should also be presented in the
GAZETTE. SpeedScript, a word
processing program developed
and enhanced here, was origi-
nally presented in the pages of
the January 1984 GAZETTE. An
enhanced version of it was pre-
sented on the May 1984 GA-
ZETTE DISK as, among other
things, a bonus for those pur-
chasing the first DISK issue.

Another version of
SpeedScript has been in the
works for additional machines.
This enhanced Speedscript 3.0,
is written for the Apple and
Atari computers as well as for
the Commodore computers.

We enhanced it for COMPUTE!;
we developed additional ver-
sions for the COMPUTE! market.
Some of those who wrote took
the position that SpeedScript
"belongs" to the GAZETTE. We
disagree. As publishers, we have
a right and obligation to present
all of our respective audiences
with a valuable product- — chosen
for its utility and appeal. The
GAZETTE cannot maintain or
continue to provide 20 or 30
percent of its editorial space for
SpeedScript listings; COMPUTE!
cannot either. We do think it
fair to provide original listings,
enhancements, etc. of major
products as they are developed.
This we have done in both of
our magazines.

Each of our publications
has large Commodore constitu-
encies. Each has large and
nonoverlapping circulation
groups. COMPUTE!, our flagship
publication, has covered the
Commodore market since its
first issue in the Fall of 1979.
COMPUTE! has published many
breakthroughs over the years
and will, of course, continue to
do so. The GAZETTE will con-
tinue to enjoy its share of Com-
modore events, but it will not
publish them all. Our two dif-
ferent magazines do in fact
share some audience charac-
teristics, so it is inevitable that
there will be some overlap of
purpose.

As publishers, we must
maintain two useful, functional,
dynamic publications that serve

their respective readerships. We
feel that we do that well; we
plan to continue to do so. As
readers, you must expect that
COMPUTE!, the parent of GA-
ZETTE, will continue to print its
fair share of major Commodore
information. Our premise in the
past, and one we maintain, is
that COMPUTE! is a more techni-
cally advanced publication than
GAZETTE. Naturally, there will
be times and areas where there
is a readership overlap. We try
to minimize them; we cannot
totally escape them.

We do not see the two
magazines as mutually exclusive
publications and will continue
to provide you with a premium
editorial product in both. Over-
lap, as always, will be held to a
minimum.

We should also address,
more specifically, the question
of audience. What kind of per-
son reads COMPUTE! books
and magazines?

Over the years, the audi-
ence has changed. When first
started in 1979, COMPUTE! was
read by a small and often
strongly partisan group of en-
thusiasts. The magazine at-
tempted then to serve the needs
of a few thousand minds.

The majority- -then as
now — owned self-contained,
complete computers like the
Commodore PET, Atari, and
Apple, but there were also own-
ers of the "computer-on-a-
board" AIM computer,
manufactured by Rockwell. A

COMPUTE! Publications, the leading home computer publisher, brings
you the exciting story of the home computer industry. This book takes the
reader into a vivid, dramatic world where a powerful, brilliant businessman
almost single-handedly fashions the American consumer computer industry.

A survivor of the Nazi Holocaust, Jack Trarniel took a tiny typewriter parts company and
built it into a major American corporation. In the process, he became a modern corporate
legend. Some of his vice presidents thought he was a saint; some thought he had the
world's hardest heart. But few deny the brilliance of this complex entrepreneur.

For the past four years, Michael Tomczyk has been Tramiel's right hand man. Through-
out Commodore's explosive rise to leadership in the computer field, Tomczyk was a close
insider. And, most importantly, Tomczyk is a keen observer and takes you where the action
is.

section of the magazine was
also devoted to the now defunct
Ohio Scientific line.

The first few issues had a
distinctly hardware-technical
texture, reflecting the interests
of some of the hackers and sci-
entists who were the first to as-
semble their own machines.
"Retrofitting ROMs" and
"Microprocessors for Nuclear
Instrumentation" are examples
of articles which appealed to a
far larger percentage of the
readership in the early days.

Reviews covered generally
the same territory as they do to-
day: word processors like
WordPro, languages like Logo,
and a hard disk drive, the Cor-
vus IIA, with 9.6 megabytes for
$5,300 which works out to be
1,811 bytes per dollar. (Current
hard disk memory prices range
between 10,000 and 20,000
bytes per dollar.)

But perhaps most revealing
are the ads. Many of them were
for hardware add-ons for the
do-it-yourself home engineer:
motherboards; EPROM
firmware; a computer-on-a-
board kit with BASIC built in
and 4K RAM for $550; keyboard
kits. Then, too, the prices were
much higher. The then new 32K
RAM Commodore PET went for
$1,300; the 48K Apple II Plus
for $1,500.

As computers became more
commonplace and easier to op-
erate, an entirely new audience
began to arise: the recreational
computerist, someone who

wanted to learn about comput-
ers and programming, but didn't
want to actually build the ma-
chines. In the past several years,
this has become the majority
audience for COMPUTE!
Publications.

Most of our readers are in-
terested in the impact of com-
puters on society and want to
be intelligently informed about
the uses of these new machines
and the way they work. In some
senses, this means software:
how do people communicate
with computers, what products
are available to make computers
more useful, what software from
COMPUTERS books and maga-
zines will be a valuable addition
to the reader's program library?

Although we receive hun-
dreds of letters from readers
each week, we read every one.
Some readers, particularly
young people and parents, ex-
press interest in our game pro-
grams and educational software.
Many others enjoy learning
more about programming and
value utilities such as
"TurboTape" and "TurboDisk,"
which greatly improve access
speed to mass memory. Other
popular programs include
BASIC enhancement packages,
sound and graphics tutorials,
and general-interest features like
weather forecasting and, of
course, the SpeedScript word
processor.

Over the years, we editors
at COMPUTE! Publications have
read many thousands of letters
ranging from severe criticism to
unqualified praise. Most letters,
of course, contain a little of
both. In addition, each month
many readers fill out our Edi-
tor's Feedback cards and those,
too, are carefully studied.

No publisher serving the
needs of more than a million
minds a month can hope to sat-
isfy them all in every way. But
that is our goal and our constant
effort.

Choose the SAT
program with less

The idea behind choosing a com-
puterized SAT program over a manual
is to save you from piles ot paperwork.
But surprisingly two of the best-known
programs come with big, fat manuals
and only 2 or 3 double-sided
disks.

When that much informa
tion is put into the manual,
what's left to put into the
computer?

Why not buy a computer
program that's really a
computer program? Buy The
Perfect Score from Mindscape for
just $69,95*

It has 6 double-sided disks and a
real skinny manual. It even has print-
out capability and a continuous
on-screen clock. All this makes The
Perfect Score more computerized
than those others.

Now, if this cold logic fails
to convince you, perhaps an
emotional appeal to your
sense of patriotism and social
consciousness will. Your choice
is this. Either you buy their SAT,
which kills innocent trees
to make all that paper. Or you
buy our SAT with 6 disks and Save
America's Trees.

est version is then saved. To run the program,
just type RUN.

Diane Sheairs

A lot of programmers use this trick to save a little
typing time, It's even simpler to do with tape, be-
cause you can change line 2 to 2 SAVE "program
name". You don't have to scratch the old program
before saving. Thanks for sharing this with us.

Asking For Trouble

I have several commercial programs on disk.
Most are no more than 100 blocks long. What I
would like to do is mark the (copy-protected) er-
ror tracks as allocated, so I can use the remaining
500+ blocks for my own programs. I tried the
Block-Allocate command, but it didn't seem to
work.

James E. Shaw

10 COMPUTED Gazette May 1985

It's sometimes possible to save programs on disks
containing commercial software, but we strongly
recommend not trying it.

Many software co?npanie$, as part of their copy
protection, have a unique disk operating system
(DOS) which stores disk information in a format
that's incompatible with the normal 154.1 DOS.
Even if you allocated the error tracks, you couldn't
use the disk for your own programs.

Other commercial disks may contain "sig-
natures/' or code words, in seemingly blank disk
sectors. When the program is. first run, it checks for
both the error tracks and the hidden signature. If
you happened to save a program to the coded sector,
the commercial program would not run.

The potential loss outweighs the potential sav-
ings. Putting programs on a commercial disk could
save you the cost of a new disk, but you might lose
the software that cost you ten times as much.

TV Interference

I'm not able to load any programs with the TV
on. When it's off, they load perfectly without any
problems. Can you explain what's going on or
how I can fix this?

Stephen D. White

You didn't indicate whether you're using tape or
disk, so we'll guess you have a Datassette, which is
more sensitive to magnetic interference.

Picture the process of loading from tape. A
magnetic pattern on the tape is read by the cassette
player, sent through the cable, and put into the
computer's memory.

The magnetism generated by your TV is scram-
bling the program as it is read from the tape. The
answer? Move your cassette drive and cable as far
from the television as possible. If this doesn't work,
try shielding the cable.

The same advice applies to owners of disk
drives. If the television is too close to the drive, it
can interfere with disk access.

Thanks for the information.

Readers should note that if you disable the key-
board in direct made, you won't be able to enter the
POKEs to get it back because, of course, the key-
board is disabled. RUN /STOP-RESTORE still '
works, unless you've disabled it too, and loill make
the keyboard work again. Also, strange things hap-
pen when you POKE22,35 to stop the printing of
line numbers. For one thing, printing a string inside
quotes (PRINT "ABC") won't work, although string
variables can still be printed. Other POKEs may
have unexpected side effects— for example, changing
the cursor speed makes the jiffy clock unreliable.

Here's one more useful series of POKEs. If you
accidentally type NEW and want to get the program
back, enter this line in immediate mode:

For the VIC: POKE4098,1:SYS50483:POKE45,PEEK(34):

VIC owners with SK or more expansion should
change the first POKE to POKE4610,!. This short
UNNEW program can be helpful.

A Bug In String Values?

I'm having a problem with the VAL and STR$
commands in BASIC. If a string is converted to a
value and then back to a string, an extra space is
somehow added to it. For example, A$ = "99":
A = VA L(A$) : A$ = STR$(A):PRl NTLEN(A$) re-
turns a length of three instead of two. A$ has be-
come (space)99. Is my computer defective, or is
there a glitch in Commodore BASIC 7

Scott W. Whittlesey

No and no. As some programmers might say,
"That's not a bug, that's a feature."

The reason for tiiis feature is that numbers can
be positive or negative. STR$(—99) turns out to be
" — 99" with a minus sign in front, but no extra
space. To be consistent, positive numbers are pref-
aced by a space which, in a way, signals that the
number is positive.

If you want to eliminate the space, use this
line: A$=MID$(STR$(A),2). If the variable A hap-
pens to be negative, the minus sign will be stripped
off.

For more on the subject, see Michael lomczyk's
column "BASIC Magic" elsewhere in this issue.

A Play-It-Once Game

I recently noticed an ad for a game about dun-
geons. But someone told me it was only useable
once! i would like to know if this is true.

Tim M. Adamec

If it's about dungeons, it's probably an adventure
game, which is like a computer story where you
play the role of one of the main characters.

You usually begin such a game as a low-level
novice character who has certain rankings for
intelligence, strength wisdom, dexterity, and so on.

You guide your character through a magical
dungeon, a spaceship, or some other kind of strange
world, maybe even the subways of New York. You
travel through the world, fighting against monsters,
meeting sages and dolts, and collecting magical or
monetary treasures. As you accumulate experience
points and treasure, your character gains power.

The goal may be ven/ specific- -finding the sil-
ver sioord and leading the good army against the
evil magician, for example. Once you defeat the bad
guy and save the princess, the game's over. In a
sense, the game is playable only once, although it
may take you six months or longer to solve it. These
games are like difficult crossword puzzles. They
each have a definite answer but take a long time to
solve.

Other adventure games can create brand new
puzzles with brand new solutions. If you get tired of
exploring one world, tell the computer to create a
brand new one.

Still other adventures are open-ended. There's

The Smallest Piece Of
Information

More and more, I see articles refer to bit
manipulation. The November GAZETTE said that
on a VIC-20 the first three bits of 36879 control
the border color. Bit #3 (fourth bit, actually) con-
trols normal/reverse text. And the top four bits
control screen color.

I realize that POKEing 36879 will change
border and screen colors, but I can't break it
down to a bit by bit level, Does it follow binary
rules?

Larry Nichols

Although you POKE using decimal, your VIC stores
the numbers in binary, using bits, the smallest piece
of information.

For example, if you POKE 36879,43 on a VIC,
the screen is red with a cyan border. You might
think of the number as 43, but the VIC stores it as
00101011. The first three bits (starting from the
right) determine the border color, which means that
anytime you POKE a binary number xxxxxOll into
36879 the border is cyan (the x's can be O's or l's —
it doesn't matter). And anytime you POKE OOWxxxx
into 36879, the screen will be red.

Here's an easy conversion routine to get from
decimal to binary. Let's say you want the binary
equivalent of decimal 43.

divide by 2 1 2 5 10 21 43
remainder 001010 1 1

Write down 43 and divide it by two. The an-
swer is 21 (write it to the left of 43), with a remain-
der of 1 (put it underneath). 21/2 is 10 (remainder
of 1). 10/2 is 5 (no remainder). And so on, until you
reach 1/2 is with a remainder of one. From then
on, it's all zeros. The pattern of ones and zeros
underneath is the binary equivalent of the number
you started with.

For more information about bits and memory,
see the March "Machine Language for Beginners"
column. For more about turning bits on and off with
AND and OR, see last month's "GAZETTE Feedback."

Using Capital Letters

I've been trying to write a program that handles
chemical elements:

10 forx=lto4:reada$:printa$:next
20 data Na,Cs,Ba,Cl

While the computer is in lowercase mode, it
won't accept uppercase letters in DATA state-

14 COMPUTE'S Gazetre May 1985

ments. It prints a, s, a, and 1. How can I get my
64 to read the capitals from DATA?

Paul Porter

The solution is to enclose each item in quotes:

20 data "Na","Cs","Ba","Cl"

This allows you to have DATA lines with cap-
ital letters as well as special characters like cursor
movements and color changes.

The first quotation mark signals the beginning
of quote mode, which makes the computer READ
each item literally. The second quotation mark is
necessary to get out of quote mode, so the commas
can separate the individual DATA items.

This same method can be used to put capitals
and graphics characters into REM statements.

To make sure you're in upper /lowercase mode,
PRINTCHR$(14) at the beginning of the program.
Printing CHR$(142) gets you back to
uppercase /graphics. To prevent the user from acci-
dentally pressing SHIFT -Commodore key,
PRINTCHRSm to disable the case change. CHR$(9)
re-enables case changes.

Printing Quotes Inside Quotes

Is it possible to use quotes (") to show a title in-
side a PRINT statement? For example,

10 print'The story "A Wrinkle In Time" is an
interesting book."

Johnny Petroschek

Quote mode bedevils many new owners of Com-
modore computers.

Letters inside quotes are just letters and can be
used in PRINT or DATA statements. Outside of
quotes they're treated as variable names.

There are two ways to force the computer to
print quotes:

10 print'The story ";chr$(34);"A Wrinkle In
Time";chr$(34);" is an interesting book."

10 print'The story 'A Wrinkle In Time' is an
interesting book."

CHR$(34) is the quote character, and you can
print a CHR$(34) anytime you want quotes. But you
have to get out of quote mode first, olhenvise you'll
get the letters c-h-r-$-(-3-4-). To simplify things,
define a string variable at the beginning of the pro-
gram, bk$ = chr${34) + "A Wrinkle In Time"
+ chr$(34) and then use bk$ in any sentences that
mention the book.

Or you could use apostrophes (single quotes) in
place of real quotation marks by typing SHIFT -7 as
a replacement. Apostrophes do not affect quote
mode.

INTRODUCING THE FAST LOAD
CARTRIDGE FROM EPYX.

You're tired of waiting forever for your Commodore 64
programs to load. But it's no use glaring at your disk
drive. Calling it names won't help, either. It was born
slow — a lumbering hippo. You need the FAST LOAD
CARTRIDGE from EPYX. FAST LOAD transforms
your Commodore 64 disk drive from a lumbering hippo
into a leaping gazelle. With FAST LOAD, programs
that once took minutes to load are booted up in a matter
of seconds.

FAST LOAD can load, save and copy your disks five
times faster than normal. It plugs into the cartridge port

MM

of your Commodore 64 and goes to work automatically,
loading your disks with ease. And that's only the
beginning. You can copy a single file, copy the whole
disk, send disk commands, and even list directories
without erasing programs stored in memory.

And unlike other products, the FAST LOAD
CARTRIDGE works with most programs, even copy
protected ones, including the most popular computer
games.

The FAST LOAD CARTRIDGE from Epyx. Easy
to insert, easy to use and five times faster. So why
waste time waiting for your disks to load?

Speed them up with FAST LOAD!

users to abandon our cassettes and purchase a
disk drive? Are tape operations incompatible
with modem operations?

David Rice

Yes, tape operations are essentially incompatible
with modern operations, with some exceptions.

Timing is very important when you're using
tape. When you read from or write to tape on a 64,
the screen goes blank. The raster interrupt routine,
which refreshes the screen, takes too much time, so
the screen is turned off during tape operations.

There's another type of interrupt, called a Non-
Maskable Interrupt (NMI). RUN /STOP -RESTORE
causes one type of NMI. The RS-232 port (including
modem communications) can also cause an NMI. As
the name suggests, "nonmaskable" means the inter-
rupt cannot be stopped (masked).

RUN /STOP-RESTORE always interrupts tape
operations. Similarly, a signal received from the
modem always interrupts the computer. Both can
disrupt tape communications.

Furthermore, there are several memory loca-
tions which serve dual purposes—they are vital to
both RS-232 and Datassette communications. Loca-
tion 171, just one example, functions as RS-232 in-
put parity during modem operations and also as the
cassette leader count. Some of these bytes are likely
to be garbled if you try downloading directly from
modem to tape.

This incompatibility prevents you from using a
cassette drive while you're online.

But there is telecommunications software avail-
able on tape. You can load the program from tape
before making the connection (as long as the cas-
sette drive is off while you're logged onto the bul-
letin board or network). And some software allows
you to download to memory and later, after you
hang up, save the memory to tape or disk. One ex-
ample is "PlusTcrm," published in the February
1985 issue of COMPUTE!, our sister magazine. It
downloads to a memory buffer, and you can later
save the file to tape or disk.

What Is Hi-Res?

What is high-resolution (hi-rcs) mode, as op-
posed to the normal screen mode? I've tried the
four-line program on page 123 of the Commodore
64 Programmer's Reference Guide, but get only the
"garbage" they describe.

David G. Diedrick

Normal screen mode is 40 characters ividc and 25
lines long on a 64, Plus/4, and 16. A VIC screen is
22 characters by 23.

POKEing characters to the screen is low-
resolution, 256 characters in 1000 (40 X 25) po-
sitions (506 on a VIC).

But the screen of a 64, Plus/4, or 16 is really

16 COMPUTE! s Gaieffo May 1985

320 dots across (40 characters, each 8 dots wide)
and 200 dots down (25 X 8). The dots are usually
called pixels, an abbreviation for picture elements.
Hi-res mode turns these individual pixels on and
off.

The Commodore 64 has a special hi-res mode.
Instead of 1000 characters on the screen, there are
64000 (320 across by 200 down) different pixels to
switch on and off. Unfortunately, the details of how
to program in hi-res ivould require a separate arti-
cle (see "Hi-Res Graphics Made Simple" in the Au-
gust 1983 GAZETTE or COMPUTEl's First Book of
Commodore 64 Sound and Graphics). You could
also consider the purchase of the 64 Super Expander
(see the November 1984 gazette for details).

To get hi-res on a VIC, you must redefine
characters, printing them to the screen and turning
pixels within the custom characters on and off.
COMPUTED First Book of VIC contains programs
to do this.

The Plus/ 4 and 16 are even more sophis-
ticated, with a built-in hi-res mode and BASIC com-
mands like GRAPHIC, BOX, CIRCLE, DRAW,
LOCATE, and PAINT. These commands make it
simpler to work in hi-res.

VIC/MPS-801 Compatibility

Commodore has started marking their MPS-801
printers "FOR USE WITH THE C-64 ONLY."
Figuring it would work with the V1C-20, I
bought one. Besides, the salesman said it was
returnable.

Some listings printed very well, others did
not. The 801 has a 90-character buffer and the
VIC transmits data faster than the 64. It seemed
to me that this combination was causing the
buffer to overflow.

Then you published the solution to the
problem in the November GAZETTE. The "Slow-
poke" program from "Power BASIC" slows
down printed output to the screen or printer.
POKE a speed number 3 (in line 10) for program
listings. Printing graphics requires a higher value,
10 or more. It's the answer to the incompatibility
of the VIC and 801.

Bob Shelor

You've found an interesting, though unintended,
application for "Slowpoke." We're sure some of our
readers will appreciate this information.

You're right about the VIC being fast. It consis-
tently beats the 64 and Plus/ 4 in benchmark tests.
A VIC not only calculates faster, it sends signals to
peripherals faster. The 1540 disk drive, originally
designed for the VIC, transmitted data too quickly
for the 64 and was deliberately slowed down when
it became the 1541. Also, the screen has to blank
when loading programs from tape into the 64, to
give the processor a little more time.

Is Terminal Software Necessary?

Can I use the 1650 Automodem even without
the terminal software?

Steve Myers

Without software, the modem won't be much good
for communicating. The software is what makes the
hardware work.

The 1650 is packaged with a terminal program.
The outside of the box should indicate whether a
tape or disk is included.

Later in your letter you say you have a disk
drive and happened to get the terminal software on
tape. If you know someone who ozvns a Datassette,

Reading Sprite Collisions

I am writing a machine language game, but am
experiencing difficulty with detecting the col-
lision of two sprites. How do you check for the
collision of sprites one and two in machine
language?

Cameron Mackenzie

You detect sprite collisions in machine language
(ML) much the same as you do in BASIC, although
the speed of ML introduces some difficulties.

In BASIC, once you've defined the sprites and
started moving them around the screen,
PEEK(53278) tells you if two or more sprites have
collided. A zero indicates no collisions; any other
value means two or more sprites have bumped into
each other. Collisions can occur on or off the screen
area. If a sprite is turned off, it cannot be involved
in a collision.

A sprite fits into a rectangular area 24 pixels
across, 21 pixels down. In single color mode, pixels
can be on (visible) or off (transparent). The collision
register at 53278 only checks for visible pixels. If a
transparent pixel from one sprite overlaps with an-
other, there's no collision.

You also have to be aware of several quirks.

Multicolor mode lets you paint sprites with up
to four colors. Color zero (00) is the same as the
screen color, and counts as transparent. Color one
(01) is taken from the first multicolor register. It also
counts as transparent. Even though you can see
color one on the screen, the collision register rec-
ognizes only colors two and three.

The eight bits of 53278 correspond to the eight
available sprites. Multiple collisions are hard to de-
code, however. If sprite zero hits sprite one, and
number two hits number three, PEEK(53278) yields
a 15 (binary 00001111). You can't tell by the bit
pattern which sprites collided with which others.

Finally, PEEKing 53278 clears (sets to zero) the

IB COMPUTE'S Gazette May 1985

register. It will stay cleared until another collision
happens. BASIC programmers should store the value
in a variable; ML programmers should store it
somewhere in available memory.

This last feature is related to the "screen re-
fresh routine." Sixty times a second, a special chip
in the 64 redraws the screen. At the same time it
draws sprites and sets the collision register.

Machine language instructions run much faster
than 60 times a second. In between screen refreshes,
the computer can execute a few thousand ML
instructions. You may have to synchronize the pro-
grant with the refresh routine or slow it down to get
good readings from the collision register.

There's also an advanced ML technique where
you set up an IRQ interrupt to occur whenever two
sprites collide. Memory locations 53273 and 53274
control this type of interrupt (they're also used for
raster interrupts and reading light pens). Infor-
mation on this programming technique can be found
in Mapping the 64 from COMPUTE! Books.

DOS And The Wedge

I recently purchased a 1541 disk drive and have
a few questions regarding the Disk Operating
System (DOS). When I run the DOS Wedge, I
get the DOS Header of V5.1/071382. But if I use
the reset command @UJ, then read the error
channel with @ I get 73,CBM DOS V2.6
1541,00,00. There's no error when I do this, but
is it really a DOS mismatch? I haven't en-
countered an error #73 any other way.

Dave Hite

There's only one Disk Operating System in your
1541. It's there, inside the drive, whenever you turn
on your 1541. It's a program stored in the disk
drive's memory. The DOS Wedge program on the
1541 Test /Demo disk (packaged with the drive) is a
program which loads into your computer's memory.

Having the Wedge program running (in your
computer) makes it easier to access the various disk
commands (in the drive).

It doesn't matter much which version of the
Wedge is working with which version of the 1541
DOS. You have version 2.6 of DOS and version 5.1
of the Wedge (written on 071382— July 13, 1982,
which was not a Friday the 13th, in case you're
superstitious). They're two separate programs, and
the version numbers are not related to each other.

Error 73 shows up when you try to use a 1541
with a disk formatted on one of the earlier Com-
modore drives, like the 2031. The two disk drives
are read- but not write-compatible.

The version number (and a false error 73) also
appears in the error channel when you first turn on
the disk drive, or reset it using Uf. It's not a real
error 73, it's more like an announcement of which
version of DOS you have. <H?

V,

Taking the plunge into tele-
communications can be as
exciting and challenging as
any aspect of computing. But
to get the most out of this
burgeoning field, you need
to understand the basics bit
by bit.

TO«\\\\W«\\

w

hen horror novel-
ists Stephen King
and Peter Straub
recently collabo-

rated on the bestselling book,
The Talisman, their work had an
unusual twist. The coauthors ex-
changed portions of the manu-
script almost instantly whenever
they felt like it — even though
they were at opposite ends of
the country.

King, from his home in
Maine, reportedly sent and re-
ceived new material and revi-
sions over the telephone as his
word processor telecommuni-
cated with Straub 's in
California.

King and Straub are not the
first to use this form of commu-
nication. Theirs is just one ex-
ample of the many ways
computer-based communica-
tions is changing how we work
and play. Thousands of Com-
modore owners are already tele-
communicating — connecting

their computers to other com-
puters by telephone line. And if
industry figures are correct,
thousands more are venturing
into this field each month.

For many computer owners,
however, telecommunications is
an intimidating and confusing
procedure. Users who are ex-
cited about learning to program
or to use word processors and
other commercial software, in
many cases won't take the step
into telecommunications. And
yet many students of technology
believe this aspect of computing
holds the greatest promise in
the long run.

"I never got into telecom-
munications because I was
never convinced that there was
much out there that I wanted to
tie into. And I was intimidated,"
admits Ken Skier, a long-time
computer user who not only
conquered his reservations, but
went on to write SkiWriter 11, a
"communicating" word proces-
sor available for the Commo-
dore 64. "Parities, stop bits,
word length — there's an awful
lot of jargon associated with
telecommunications; far more
than with any other aspect of
personal computing."

Once he was convinced that
telecommunications indeed held
rewards for computer users,

Skier went further and decided
that the most useful combina-
tion would be software which
would let the user easily mix
writing (word processing) and
communicating.

"Nobody does telecommu-
nications as an end in itself," he
argues. "You don't get online
with CompuServe (a telecom-
munications network), and just
get some information. You get
some information in almost all
cases because you're writing
something."

When Skier began to de-
velop his program, he knew
personally what daunted many
would-be users. "I didn't have
to wonder what the newcomer
to telecommunications might
fear — because that was me."

SkiWriter II and an increas-
ing number of other tele-
communications programs are
broadening the accessibility of
this growing field. The ultimate
goal, of course, is to make tele-
computing as easy as using the
telephone. But as Skier is the
first to admit, we're a long way
from that.

Many terminal programs
still require a user to make a
variety of decisions, some of
which can be intimidating to a
newcomer.

Perhaps the easiest way to
untangle the jargon is to fol-
low the path taken by some
information, from the time it
leaves your fingers at the Com-
modore keyboard to when it
reaches the phone lines.

Sending a message via
computer means following cer-
tain rules, just as a cross-
country vacation would necessi-
tate a plan, a vehicle, adherence
to specific travel requirements,
and a destination. A telecommu-
nicating computer has its own
set of similar preparations. They
may at first glance seem far
more confusing, but that's only
because you're not yet familiar
with them.

Before deciding on a mes-
sage, first we need the basic
system components to begin. As
most computer users quickly
learn, there are onlv three
things needed to get started
other than the computer: a
modem, which connects the
computer to a telephone, the sec-
ond component; and a terminal
program which lets you tell the
computer and modem what,
when, how, and where you
want to send.

Commodore owners have a
growing field of modems and
terminal software available.
Their capabilities, complexities,
and prices vary widely. Before
explaining how these two com-
ponents work together, let's

turn for a moment to the key-
board and our message.

When Alexander Graham
Bell shouted into one of
his early telephone transmitters,
Mr. Watson, come here, I want
you!, his assistant, Thomas A.
Watson, heard the words sev-
eral rooms away as they filtered
unevenly through a test re-
ceiver. Those words, so the
story goes, made up the first
telephone transmission. If we
type those same words into a
computer with the intent to
transmit them to a friend's com-
puter, we can quickly see some
major differences and similar-
ities between computer data
transmission and telephone
voice transmission.

The telephone we use today
is an analog device, as was the
crude instrument Bell used for
the first transmission. An analog
system is one that accepts con-
tinuous values between two ex-
tremes. A painter, for example,
can mix black and white into a
variety of different gray-tones.
The sounds sent over the phone
lines are analog. But as we pre-
pare to send our message via
computer, each letter, or charac-
ter is represented in the comput-
er's memory in discrete digital
form. Each bit in memory holds
a one or a zero; there are no
"gray" numbers in between.

When Bell shouted his mes-
sage to Watson, his voice tones
were converted into a series of
modulating electrical impulses.
But when we type those same
words into the computer, they
become a string of ones and ze-
ros — the binary language which
is the heart of a computer's
number processing. Whether we
think of these ones and zeros as
on/off or yes/no states, your
Commodore computer treats
each character in the sentence
as a row composed of bits of
data.

Each letter, number, or

graphics character in your com-
puter has its own assigned digi-
tal representation. In order for
these to be uniform, most com-
puters follow the American Stan-
dard Code for Information
Interchange (ASCII) formula, a
standardized method of encod-
ing characters.

In standard ASCII, Watson
becomes the following binary
code: 1010111 (capital W),
1100001 (lowercase a), 1110100
(0, 1110011 (s), 1101111 (o),
1101110 (»)■ All computers
which use what is called true
ASCII will be able to interpret
that. Commodore, however,
uses its own form of ASCII
(called Commodore ASCII or
PETASCII), which varies some-
what from the above. One dif-
ference is that true ASCII uses
seven bits per character, while
Commodore ASCII uses eight.
As our message is being pre-
pared for departure from the
computer, the binary bits must
be arranged in a particular fash-
ion in order to travel success-
fully to another computer.

When your fingers type the
letters W-a-t-s-o-n, they're tem-
porarily stored in memory.
Before transmitting, they may
have to be translated into true
ASCII.

That's where we pick up
the intertwined functions of the
modem and the terminal soft-
ware. The modem will convert
our digital message into an ana-
log format compatible with the
telephone lines. And the termi-
nal software will make sure that
the message is prepared prop-
erly for the journey.

Perhaps the most popular
modems for the Commodore 64
and the VIC-20 computers are
Commodore's own 1600 VIC-
Modem and 1650 AutoModem.
New modems from Commodore
are being introduced, and a host
of other companies have created
modems for these computers.
Although the capabilities and
prices vary, the basic function of

'hen you can have Mo?

Mitey Mo turns your Commodore 64

Into a telecommunications giant.

It's the best-performing modem

with upload/download.

Mitey Mo is being hailed as
"the best price/performance com-
munications package available:'
Its software has received the endorse-
ment of the U.S. Commodore Users
Group, which gives a money-back
guarantee to members. It is truly the
industry standard, and no wonder.
It's the most user-friendly modem you
can buy -it will take you online
faster and easier than anything else.

Mitey Mo opens up a world of
practical and exciting uses for your
C-64. It lets you send and receive
electronic mail, link up with commu-
nity bulletin boards, play computer
games with people in distant places,
tap into library resources, and
much more. All at your convenience.

Until Mitey Mo, Commodore's
1650 Automodem was the obvious
choice when you went looking
for a modem for your computer. Like
Mitey Mo, it has "auto
answer"— it receives
data while unattended
And both modems are
"auto dialers"—
you dial right on
the computer's
keyboard. But
that's about
where the simi-
larity ends.

numbers sequentially But suppose you dial
a number and find it's busy Mitey Mo has "auto
redial"— it hangs up and redials immediately
until it gets through. With the other modem
you have to redial each time - and somebody
with auto redialing can slip in ahead ot you.
Mitey Mo is menu driven. It lists the things
you can do on the screen.
Select a number and you're
on your way Since Auto-
modem isn't menu driven,
you'll be hunting through
the manual a lot.

With Mitey Mo, your
computer's function
keys are program-
mable— you can
save yourself plenty

of keystrokes. Not so with the other
modem. And only Mitey Mo lets you
store data to review or print it later.

Mitey Mo has just one switch,
the Smart 64 software does the rest.
With the other modem you'll have
to remember to check three switches,
otherwise you may be answering
when you mean to be originating.

Mitey Mo is halt the size of the
other modem. The very latest tech-
nology allows miniaturization and
increased reliability as well. Mitey
Mo is so reliable, we gave it a full
three-year warranty. The other
modem gives 90 days, then you're on
your own.

Not only will you find Mitey Mo
mighty useful, you'll find it mighty
reasonably priced. When you buy it,
you'll get S15 of CompuServe access
time free, as well. See your dealer or
call us directly to order your Mitey Mo.

VIP Terminal, one of the most
powerful ami flexible terminal soft-
ware programs for the Commodore
64.

There are only three deci-
sions to be made in order to
prepare the modem, and three
other basic options for the ter-
minal software. Although many
more possible changes can be
made in sending and receiving
information, they are either ad-
vanced techniques you'll learn
(if you need them at all) after
the basics or simply cosmetic al-
terations. While these first six
settings certainly qualify as part
of the telecommunications jar-
gon Skier mentioned, they are
relatively painless once you un-
derstand their functions.

Before our message enters
the modem from the computer,
the three things the modem
must know are 1) whether we
are originating or receiving data,
2) what speed our data will
travel, and 3) whether we will
have our message echo back to
us letter by letter as a form of
error-checking. Put another
way, these options are the mode
(originate or answer), the baud
rate (speed measured in bits per
second), and duplex (full or half).

If we wish to send a mes-
sage, we would set the modem
to originate and our destination
computer would be set to an-
swer. However, as long as the
two computers are set on differ-
ent modes, they can both send
and receive.

The speed of transmission
for most Commodore telecom-
munications is between and
300 bits per second (bps), or,
more commonly but less techni-
cally correct, 300 baud. There
are modems and terminal soft-
ware which handle higher trans-
fer rates— such as 1200 and
even 2400 bps — but they are
less prevalent among Commo-
dore users and generally more
expensive.

If we think again of the
word Watson, with its seven bi-
nary digits per letter, we can get
a better idea of the speed of 300
bps. Each letter can have as
many as three or four extra bi-
nary digits — ones or zeros — as a
part of the way in which the
terminal software packages the
data for transmission. So, if
there are approximately ten bits
per letter, or character, being
sent, then 300 bits per second
translates roughly into 30 char-
acters per second. Our word,
Watson, would take approxi-
mately one-fifth of a second to
send at 300 bps. And Bell's en-
tire sentence to Watson would
require about one second. 1200
bps transmission would be four
times faster, and 2400 bps, eight
times more rapid than 300 bps.

One of the oddities of our
telephone network is that it's
currently in transition from an
analog system to a digital sys-
tem. Eventually, all telephone
signals will be digital, but the
process of changing the mam-
moth telephone grid takes time.
For now, your computer will
send digital bits to the modem,
which will translate those into
an analog signal. It will then
likely travel on local lines in an-
alog form until it reaches a main

switching station, a microwave
carrier, or a satellite transmis-
sion. Since an increasing num-
ber of these are now becoming
digital carriers, your message
may well be translated into digi-
tal form again through pulse
code modulation, then back to
analog when it arrives at an-
other local telephone system,
and finally demodulated to digi-
tal in your target computer's
modem — all in less than a
second.

The third option, duplex,
provides the capability for error
detection between sending and
receiving computers. At full-
duplex, a receiving computer
echos the character sent. That is,
if you type the word, Watson,
the letter W on your screen is
actually the character received
at the other computer and sent
back to you. This, of course, ap-
plies to each character you send.
If the phone lines are noisy, you
may see a mixed-up message of
random characters. Since the
terminal software and some
modems each have full- and
half-duplex settings, follow your
terminal program's directions
carefully on this option.

For example, if you type in
the word Watson and the screen
shows WWaattssoonn, your ter-
minal program (sometimes your
modem) is probably set for half-
duplex and should be set to full-
duplex. In half-duplex, the
character you send is not to be
echoed back, and the letters you
see on your screen are gener-
ated directly from your own
computer — not an echo. Any
double-lettering on your screen
is an indication that your duplex
setting is causing your computer
to produce a character on the
screen at the same time that the
other computer's echo is
appearing.

Terminal software exists solely
to manage the transmission
of data, telling the modem what
to do and communicating with

the computer and peripherals
such as disk drives and printers.
Although terminal programs can
vary widely in their approach
and ease of use, there are only
three major options here which
you should learn from the start.
While these decisions are a bit
more technical, you don't need
to learn all of the reasons why
they work, just how they help
us communicate.

All three of these options —
stop bits, word length, and par-
ity — relate specifically to how
the terminal program packs our
message in digital bits for the
journey. Your terminal software

should help you make these de-
cisions painlessly, depending on
the type of telecommunications
you're conducting.

A stop bit (sometimes more
than one) is added, during
transmission, to the end of each
string of seven or eight bits
making up a single character.
This bit tells the other computer
where one character stops.

Word length deals with
whether the computer will treat
each character as being com-
posed of seven or eight bits.
And parity is a setting which
helps the computer determine
whether any errors have been

made in transmission. There are
several different possible
settings, but they all simply ask
the computer whether what was
sent matches exactly what was
received.

Whether you're sending a
message to a friend's computer,
gaining access to one of the
large telecommunications ser-
vices like CompuServe, The
Source, and Dow Jones/News
Retrieval, or connecting to a
computerized bulletin board,
these will be the basic decisions
from which to start.

Many terminal programs
default to the most commonly

Online Learning: The Electronic University

Commodore 64 owners can now become
college students — even earning undergradu-
ate and graduate degrees — without having
to leave their keyboards. This new approach
to education, called The Electronic Univer-
sity, includes not only online college degree
programs, but tutoring programs for chil-
dren, personal improvement courses, and
business and professional skill-building
classes. All that's required to enroll is your
computer, a modem, telecommunications
software, and the purchase of the Electronic
University Enrollment Package ($49 for
Commodore, $89 for IBM and Apple com-
puters). If a local software store doesn't
have the package, you can purchase one on-
line through the University using a credit
card. Course fees vary, and are not included
in the enrollment cost.

Operated by TeleLearning Systems,
Inc., of San Francisco, The Electronic Uni-
versity has already issued more than 10,000
user identification numbers to students.
Among the services offered are seven degree
programs, all in association with 1800 ac-
credited universities across the United
States. Included are associate degrees in Sci-
ence in Management and in the Arts, bache-
lor's degrees in Business Administration and
in the Arts, a general Master of Business
Administration (MBA) degree, and two spe-

cialized MBAs in Individual Financial Plan-
ning and Technology/Engineering
Management.

A counseling service is also offered by
The Electronic University to help prospec-
tive students select the right courses, under-
stand the degree requirements, and answer
any questions which may arise. Enrollment
automatically means membership in the sys-
tem's electronic library system, composed of
a list of books in print (eight million book
titles), an encyclopedia, political news re-
ports, environmental information, abstracts
from The Harvard Business Revieiv, and other
articles and indexes in a variety of subject
areas.

The Electronic University also supports
an online seminar series, featuring the ca-
pability for the reader to ask questions of
the speaker, to print out the seminar mate-
rial, and to request that a disk copy be sent.
Communication with instructors is handled
through electronic mailboxes supported by
the system's central computer.

Although novice computer
users often throw up their
hands as the telecommunica-

Skier says that the process
doesn't have to be intimidating.
"There is some anarchy in tele-
communications, just as there is
in personal computers generally.
But there's a lot more stan-
dardization than I had originally
expected. And it turns out that
there is a configuration for stop
bits, parity, and word length
that works on just about all tele-
communications services,"
The manufacturers of
modems and terminal software
have been steadily making the
road to telecommunications eas-
ier and more flexible over the
past few years.

The Commodore 64 menu from CDI's
Mitey Mo modem terminal software.

"We first started out devel-
oping communications software
on the Commodore 64 with the
assumption that most users
would be using such a product
for tie-in to services like
CompuServe," says Joseph
O'Hara, president of Microtech-

28 COMPUTED Gazette May 1985

nic Solutions. His company has
created the terminal program ac-
companying CDI's Mitey Mo
modem for the Commodore 64
and Plus/4 computers.

"However, we were quite
surprised over a period of
months to find that users were
buying it for all kinds of ser-
vices. We've gone through a
number of revisions in our
product to try to keep up with
the users," he adds.

For those who have hesi-
tated on whether to try tele-
communications with their com-
puters, O'Hara says that too
many people overlook the obvi-
ous: "One of the problems nov-
ices have is that they don't have
a clear idea of what they want
the software to do when they
go out and buy it. And
consequently, they're often
disappointed."

Before getting started on
the wrong foot with telecomput-
ing, take the time to learn a
few of the basics. The follow-
ing brief glossary will help
you to decipher some of the
other key words used in
telecommunications:

• Auto-Answer: the ability of
certain modems and computer
systems when left on to auto-
matically answer incoming calls
from other computer modems.

• Auto-Dial: a capacity of
some modems (with the appro-
priate software) to automatically
dial other computers. Some will
re-dial if there's a busy signal.

• Buffer: an area in your
computer's memory in which
text, programs, or files may be
stored temporarily while you
are downloading or uploading
data,

• Bulletin Board System: a
public access service based on a
computer system with an auto-
answer modem to take mes-
sages, provide a public forum,
and possibly offer programs.

• Carrier Signal: the signal
by which a computer indicates
to another computer that it is

ready to establish a communica-
tions link.

• Downloading: receiving
data, such as a file or a pro-
gram, from another computer.

• Modular Connection: a type
of telephone connector used in
today's phone system which al-
lows you to directly connect
your modem to the telephone
rather than having to place a
telephone handset into the two
cups of older acoustic modems.

• RS-232-C: a Recommended
Standard, hence RS, for serial
communications with a modem,
printer, or other device. Com-
puters without a built-in serial
interface often require an exter-
nal interface in order to attach
an RS-232-compatible modem.
The Commodore 64 handles its
RS-232 communications through
the user port. (See "Commodore
Peripheral Ports" in the March
GAZETTE.)

• Uploading: sending data,
such as a file or a program, to
another computer. <B

Telegaming

Kathy Yakal, Feature Writer

Can't find a challenging chess partner? Looking for a better
way to meet people than by leaving messages on elec-
tronic bulletin board systems? Telegaming is one of the
fastest-growing applications of telecommunications.
Here's now you can get involved.

It isn't a terrific party, but
it's too early to go home.
Let's play a game, someone
suggests. But nobody can
remember all the rules to con-
tract bridge. The Monopoly set
is missing too many pieces. Ev-
eryone has memorized most of
the answers in the first edition
of Trivial Pursuit. And some
people are starting to yawn.
Well, maybe there's something on
television.

It's not easy to get a group
of people to agree on which
game to play, what the rules
are, and how long to play.
Telegaming — playing games
over the phone lines via a per-
sonal computer and modem —
doesn't solve the problems of
indecision or tired players. But it
offers new ways to play old
games, thousands of potential
challengers across the country,
and computer games designed
specifically for use on telecom-
munications networks.

CompuServe and The
Source are probably the two
best-known networks that offer
telegames. Recently, several

30 COMPUTE! s Gazette May 1985

new networks have gone online
for the sole purpose of provid-
ing communication and
recreation.

Long-distance gaming is not a
new concept. People have
been playing games by mail for
years. One person takes a turn,
records it and sends it to his op-
ponent, who does the same. A
round of chess could take
months.

Software developers are
looking for ways to speed up
that process, whereby you can
link two personal computers via
modem and play directly be-
tween them. No third party (like
a telecommunications network)
would be necessary. While this
would allow you to play a game
with your cousin in Cleveland
in real time, the long distance
charges could become rather
costly if you happened to live in
Nova Scotia.

Telecommunications net-
works allow you to find com-
patible game partners (through
electronic mail, game forums,

and online conversations) and
play a wide variety of games,
ranging from simple board
games like checkers to
CompuServe's highly interac-
tive, fast-paced MegaWars.

You must subscribe to the
service to gain access to any of
its features. Most charge a one-
time new subscriber fee, hourly
online charges, and, sometimes,
additional charges for games.
Once you've signed up and re-
ceived a password, using the
system is generally no more dif-
ficult than calling an electronic
BBS.

A word of warning here: Be
sure to read the documentation
that comes with your member-
ship packet. Menus and help
commands within the system it-
self will guide you to and
through the game functions, but
being prepared will save you
online charges.

The creators of these net-
works report something in-
teresting: Consumers don't
necessarily demand the same
richness and depth of play they
would normally expect of a
videogame. The old favorites,
when played with someone a
thousand miles away, are just
fine for now.

Further, telegaming seems

ALL TENNIS GAMES ARE
NOT CREATED EQUAL

Over the years, game designers have brought
several versions of "tennis" to the home screen.
Unfortunately, they all resemble Atari's ten year oid
classic, Pong™. Good games all, but not real tennis.

ON-COURT™ TENNIS
Actual Commodore 64™ screen -Other versions may vary

ON-COURT™ TENNIS IS UNIQUE

ON-COURT™ Tennis by Gamestar was not
created equal-it was created better. Over eight
months in development, ON-COURT™ Tennis
captures the play and feel of real tennis, not Pong™
With Player Perspective Graphics™ so realistic,
you feel like you're on the court. With full racquet
control over groundstrokes (angle & spin), serves,
lobs and smashes. And with the kind of strategic
choices you just can't get in a Pong™-like tennis
game.

PLAY AGAINST WORLD-CLASS
COMPUTER PLAYERS

When you play solitaire against the computer,
you'll be in for the match of your life, rookie or pro.
That's because the computer players (there are
four to choose from) play like their real life counter-
parts. And their play intelligence "floats" according
to your skill. So while they like to keep you in a
match, it'll take more than luck to beat them and
join Gamestar's exclusive "Top Seeds" club.

wish you did, ON-COURT™ Tennis is ready now on

to be reviving interest in games
where popularity has waned.
"Bridge players and coffee
drinkers are about the same. All
of us are dying off at the top
end," says Terry Beam, director
of marketing for PlayNET, a
Troy, New York-based telecom-
munications network. "Both of
those activities are associated
with older people. It's a dying
thing.

"But now there are a lot of
people playing games they
haven't for years because there
is a new way to play it. They're
finding a new excitement that
wasn't there before. You can
play a hand of bridge with
someone in Sacramento, some-
one in Minneapolis, and some-
one in New York at the same
time."

PlayNET began full opera-
tion in October 1984, after sev-
eral months of market research.
Unlike other major networks,
PlayNET chose to make the
software compatible only with
the Commodore 64 because of
its high household penetration.

Finding game partners once
you've logged on to the system
is accomplished through
PlayNET's online conversation
feature, similar to the CB simu-
lator on CompuServe. Instead of
switching channels, you move
into different "rooms," trying to
find someone who will set up a
game with you. (Or, if you like,
you can just chat with people.)
PlayNET's monthly calendar
lists scheduled tournaments for
interested competitors.

PlayNET asks a one-time
registration fee of $39.95, $6 per
month maintenance charge, and
$2 per hour online billing. The
system can be accessed either
through a local Telenet number
or direct dial to their New York
number. Hours are 6 p.m. to 7
a.m. {Eastern Standard Time),
and 24 hours on weekends and
holidays.

Games currently on
PlayNET include traditional fa-
vorites like backgammon, chess,

32 COMPUTEIs Gazette May 1985

checkers, and hangman; games
written especially for the Com-
modore 64 like Quad 64 and Sea
Strike; and some not-so-familiar
games like the ancient Oriental
game, Go. PlayNET has been
working with the American Go
Association, which is pleased to
be able to introduce this strat-
egy game to a whole new
audience.

"We created PlayNET to be
fun and affordable telecommu-
nications for everybody. That's
what it's all about. People are
looking for ways to communi-
cate with each other long dis-
tance at a reasonable price, to
entertain themselves, to utilize
their personal computers."

If you're playing Monopoly
and someone quits, the game
is over, unless you want to
divvy up that player's property
and money among the other
contestants. That's the way it is
with most games.

PlayNET was designed to
simulate real-life gaming situa-
tions as closely as possible. So if
a player drops out, the main-
frame computer that runs the
system does not come in to fin-
ish the game. Nor is it available
as an opponent at the start of a
game. It's there to maintain the
system. "We wanted PlayNET
to be a system that the subscrib-
ers control," says Beam.

CompuServe, on the other
hand, has allowed the option of
playing against the computer
since games were first offered
on the system in August 1979.
Variations of board, card, and
sports games can be played
against another person or the
computer.

MegaWars was added to
CompuServe's list of telegames
in early 1982. Designed by the
Kesmai Corporation, it's an in-
teractive fantasy game in which
players create their own charac-
ters and battle to dictate the di-
rection of the universe.

Rich Baker, director of cor-
porate communications at
CompuServe, warns that
MegaWars is not for the casual
game player. "The people that
play MegaWars are extremely se-
rious," he says. "The expertise
level is verv high."

Baker advises potential
players to study the manual, ask
questions of other players in
CompuServe's games forum,
and take it slowly by starting at
the first of the Mega War's three
levels.

"MegaWars gives people the
chance to be someone else, like
the commander of a star ship.
It's different from the challenges
you face going to work," says
Baker. "And a lot of the fun is
not so much the game, but the
interaction."

Though MegaWars may be
the most sophisticated telegame
available up to now, interactive
gaming has a long way to go,
according to Baker, As modems
support faster baud rates (300
baud is too slow to support so-
phisticated graphics) and the
graphics capabilities of the ma-
chines themselves improve, the
interactive nature of telegames
will expand.

American Home Network
rang in 1985 by going on-
line with its new telecommuni-
cations service, American People
Link, Though it's billed primar-
ily as a service for home com-
puter owners to meet electroni-
cally, games should be available
by the time you read this.

The Source and Delphi, two
major telecommunications net-
works providing a variety of
information and services, have
also added games to their offer-
ings. Besides traditional board
games and card games, adven-
ture and fantasy games are
available.

Suffering from lack of fund-
ing, The Games Network did
not make its planned 1984 debut.

If successful, The Games

based games service. Subscrib-
ers would rent a special 64K

variety of educational, arcade,
and adventure games provided

companies.

Any game, whether played
electronically or at the
kitchen table, requires a lot of
thought and strategy, and,
sometimes, quick reflexes. And
in either kind of gaming, the in-
teraction between players is
often more important than the
outcome of the game itself, says
CompuServe's Baker.

Larry Dunlap, president of
The Games Network, agrees.
"The greatest game of all is
some of the other aspects of

telecommunications, ways for
people to be in touch with each

A Printer For All Reasons

Search For The Best High Quality Graphic Printer

If you have been looking very long, you have
probably discoveied that there are just too
many claims and counter claims in the printer
market today. There are printers that have
some of the features you want but do not have
others. Some features you probably dan'1 care
about, others are vitally important to you We
understand. In fact, not long ago, we were in
the same position Deluged by claims and
counter claims Overburdened by rows and
raws of specifications, we decided to separate
all the fads — prove or disprove all the claims
to our own satisfaction. So we bought printers
We bought samples of all major brands and
tested them

Our Objective Was Simple

We wanted to find that printer which had all the
features you could want and yet be sold
directly to you at the lowest price. We wanted
to give our customers the best printer on the
market today at a bargain price.

The Results Are In

The search is over. We have reduced the field
to a single printer that meets all our goals (and
more). The printer is the GP-SSOCD from
Seikosha, a division of Seiko (manufacturers of
everything from wrist watches to space hard-
ware). We ran this printer through our battery of
tests and it came out shining. This printer can
do it all. Standard draft printing up to a re-
spectable (and honest) 86 characters per sec-
ond, and with a very readable 9 (horizontal) by

8 (vertical) character matrix. At this rate, you
wilt get an average 30 fine letter printed in only
28 seconds

"NLQ" Mode

One of our highest concerns was about print
quality and readability. The GP-SSOCD has a
print mode termed Near Letter Quality printing
(NLQ mode). This is where the GPS50CD
outshines all the competition Hands down! The
character matrix in NLQ mode is a very dense

9 (horizontal) by IS (vertical). This equates to
14,400 addressable dots per square inch Now
we're talking quality printing. You can even do
graphics in the high resolution mode. The
results are the best we've ever seen. The only
other printers currently avadable having reso-
lution this high go for $500 and more without
the interface or cable needed la hook up to
your Commodore!

Features That Won't Quit
With the GP-SSOCD your computer can now
print 40, 48, 68, 80, 96, or 136 characters per
line. You can print in ANY of 18 font styles. You
not only have the standard Pica, Elite, Con-
densed and Italics, but also hue Superscripts
and Subscripts. Never again will you have to
worry about how to print HjO or X*. This fan-
tastic machine will do it automatically, through
easy software commands right from your
keyboard. All fonts have true descenders.

One of the fonts we like best is "Proportional"
because it looks most like typesetting, The
spacing for thin characters like "i" and "1" are
given less space which "tightens" the word
making reading easier and faster. This is only
one example of the careful planning put into
the GP-SSOCD.

Do you sometimes want to emphasize a word?
It's easy, just use bold (double strike) to make
the words stand out. Or, if you wish to be even
more emphatic, underline Org words. Or do
both. You may also wish to "headline" a title.
Each basic font has a corresponding elongated
(double- wide) version. You can combine any
of these modes to make the variation almost
endless, Do you want to express something that
you can'i do with words? Use graphics
with your text — even on the same line.

You can now do virtually any line spacing you
want. You may select 6, 8, 7'/i or 12 lines per
inch. PLUS you hove variable line spacing of
1.2 lines per inch to infinity (no space at all)
and 97 other software selectable settings in
between. You control line spacing on a dol-by-
dol basis. If you've ever had a letter or other
document that was just a few lines too long to
fit a page, you can see how handy this feature
is. Simply reduce the line spacing slighdy
and . . VOILA! The letter now fits on one
page.

Forms? Yes!
Your Letterhead? Of Course!

Do you print forms? No problem. This unit will
do them all Any form up to 10 inches wide. The
tractors are adjustable from AVt to fO inches.
Yes, you can also use single sheets. Plain
typing paper, your letterhead, short memo
forms, anything you choose. Any size under 10"
in width Multiple copies? Absolutely! Put
forms or individual sheets with carbons (up to 3
deep), and the last copy will be as readable as
the first Spread sheets with many columns? Of
course! Just go to condensed mode printing
and print a full 136 columns wide. Forget ex-
pensive wide- carriage printers and changing
to wide carriage paper. You can now do it all
on a standard BW" page.

Consistent Print Quality

Most printers have a continuous loop ribbon
cartridge or a single spool ribbon which gives
nice dark printing when new, but quickly starts
fo fade after a while. To keep the printers'
output looking consistently dark, the ribbons
must be changed more often than is healthy for
the pockelbook, The GP-550CD solves this
problem completely by using a replaceable,
inexpensive ink cassette which is separately
replaceable from the actual ribbon. It keeps

the ribbon loaded with ink at all times, You only
replace the ribbon when it truly wears out, not
when it starts to run low on ink. Just another
example of the superb engineering applied to
the GP-5S0CD, (When you finafiy do wear out
your ribbon, replacement cost is only $10.95.
Ink cassette replacement cost is only $5.95,
both postpaid,)

The Best Part
When shopping for a quality printer with all
these features, you could expect to pay around
$500 or more. Not any more/ We have done our
homework You don't have to worry about inter-
faces or cables. Everything is included. We are
now able to sefl this fantastic printer for
only $259.95! The GP-SSOCD is built espe-
cially for the Commodore 64, VIC-20, Plus 4
and C-16. All Commodore graphics are in-
cluded- This printer does everything the Com-
modore printers do but has more features. You
need absolutely nothing else to start print-
ing-just add paper. We also have specific
models for other computers. Call for details.

No Risk Offer

We give you a 15-day satisfaction guarantee, ff
you are not completely satisfied for any reason
we will refund the full purchase price. A 1 -year
warranty is included with your printer. The war-
ranty repair policy is to repair or replace and
reship to the buyer within 72 hours.

The Bottom Dollar

The GP-550CD is only $259.95 Shipping and
insurance is $8.00 — UPS within the conti-
nental USA If you are in a hurry, UPS Blue
(second day air) is $18.00. Canada, Alaska,
Mexico are $25.00 (air). Other foreign is $60.00
(air). California residents add 6% tax. These
are cash prices — VISA and MC add 3% to
total. We ship the next business day on money
orders, cashiers' checks, and charge cards. A
14 -day clearing period is required for checks.

sions.

At the beginning of the game, press f5 to see
the menu of magical items, then a numbered key
(1-9) to make a choice. Pressing zero (0) gives
you one of the items at random. By using f5
again, you can pick another item. During the
game, all items you have will appear at the bot-
tom of the screen.

When you're ready to begin the quest, press
f3 to be transported to a room or forest area at
random. Or, use fl to begin at a specific safe sec-
tion of the forest. You have four chances (dream
lives) to find the sword. If you fail, you can try
again with four new lives.

Movement Through Forest And
Castle

Use the joystick to move up, down, left, and
right. Diagonal moves are not allowed. Pressing
the fire button ends the game (unless you have
the cross).

There are several dozen different screens. To
pass from one to another, just move "off the

42 COMPUTEis Gazelle May 1985

screen." You cannot move through brick walls,
unless you have the boots of brickwalking. Nor
can you move through trees, unless you possess
the axe.

You'll encounter two different terrains, forest
and castle. Any area may contain treasures, mon-
sters, or traps.

The forest areas are full of trees. If you move
from one forest area to another, then travel back
to the first, you'll notice that the trees have
changed position. They migrate around the
screen while you're not looking.

The castle can be entered only through marked
doorways. Once inside, you must move from screen
to screen using doors. Do not try to use the boots
of brickwalking to move between screens.

Ordinary Door. Move your character into
a door and then off the screen to use an

ordinary door.
lAC Secret Door. A secret door is an ordinary

;;™: door that's hidden from sight. You won't

see it and can't use it, unless you have the wand

of secrets.

T Keyhole For Invisible Door. You never
see an invisible door, only the keyhole. If
you are carrying the right key (purple key for
purple door, blue for blue), the keyhole will be
illuminated.

XS Transporter. Sends you somewhere else,
i«; but things may look a little strange, trees
growing in a room for example.

Tricks, Traps, And Monsters

There are several magical items and creatures de-
signed to thwart you and your quest.

The globe of lies looks like the singing
globe, but leads you astray, away from the
sword. You can get rid of it by finding the real
globe or by having it stolen by a thief.

Cross-shaped tombstones are found in
graveyards. Zombies usually inhabit the same
area. Both are poisonous to the touch, unless you
have the cross.

Certain rooms in the castle will shake vi-
olently, jarring loose massive bricks from the
ceiling. If a brick hits you, you lose a life.

Some treasures may be visible, but are ac-
tually illusions, phantasms put there to fool you.
The wand of the way lights up the real treasures
and prevents you from being tricked.

Palpable darkness, or evil shadow, causes
some areas to be impassable. You can't travel
through a screen that is cursed with darkness.
The torch disperses the shadow and allows you
to pass through it.

Yellow disease affects your movement. Walk
forward and you'll slide backward. Try to turn

left and you'll go right. There is no cure. And
sometimes, despite your best efforts at making a
map, you'll get lost in the forest.

There are also several creatures to avoid.
Fluffers are round creatures with feet, found in
groups of four. The Cheshire bobcat is almost in-
visible, but you can see two eyes and a large
mouth. The boa constrictor brick monster tries to
encircle you with brick walls (a good reason for
owning boots of brickwalking). Thieves, out to
steal one of your magical weapons, look like you,
except they're blue, Zombies are red and are
found in numbers in graveyards.

Finding The Sword

If you have the wand of the way, the sword will
look like this:

Otherwise, it will appear as a question mark.
There are also three deadly swords disguised as
question marks. Thus, without the wand of the
way, you have a 25 percent chance of picking
the right sword. But, once you capture it, you'll
be magically transported out of the enchanted
land. The king's wizard will congratulate you on
a job well done.

Typing Instructions

Follow these important instructions to make sure
the programs are entered correctly.

Insert an 8K expander (16K or 24K will also
work). The program requires at least 8K. Enter
Program 1, which raises the start of memory to
make room for custom characters. Pay close
attention to line 4, which loads Program 2. The
line under the letter O at the beginning indicates
that you should type SHIFT-0 (L SHIFT-O is the
abbreviation for LOAD). Also, in line 4, tape
users should replace the 8 (the disk drive device
number) with a 1. Then save to disk or tape.

Next, type NEW and enter Program 2, which
creates the custom characters. Line 9 loads the
next program and, as before, the underlined O
means SHIFT-O. Again, tape users should re-
place the 8 with a 1, in line 9.

When saving program two, use the program
name "Y". Line 4 of Program 1 loads and runs
"Y" after it's done. Likewise, Program 2 loads
and runs "Z", the name you should use when
saving program three.

Tape users should save Programs 1, 2, and 3
one after another on a single tape. To play the
game, load and run the first program.

Alien Armada

John Matias

If you like the fast action of arcade games
like Space Invaders, you'll like "Alien
Armada." The original version, written by
a 14-year-old, demonstrates the versatile
sound and graphics available on the VIC.
We've added a version for fhe 64. A joy-
stick is required.

They told you it would be easy, farming on the
planet Scelor. All you'd have to do is direct the
agribots to plant the seeds in the spring and har-
vest the valuable crop in the autumn. There are
no aliens within hundreds of light years, they
said. As the shuttle pilot dropped you off, she
wished you good luck.

You're going to need good luck.

The day after you landed, the aliens came.
First the mothership, which apparently opened
up a space warp from another dimension. Then,
row after row of menacing droids. Thinking
quickly, you equipped each of your robots with a
laser to send the invaders back to their own
dimension.

The droids don't actually attack you; they
simply hover in the sky, waiting to land. But
they drop smartbombs, which are impervious to
lasers. Your only defense is to move out of the
way. The mothership also releases birds that
home in on your robots. As the birds descend,
they drop slow-moving bombs. Fortunately, you
can shoot the birds and their bombs.

Your ultimate goal in "Alien Armada" is to
get to the source of the invading aliens: the omi-
nous mothership. If you can hit it with a single
laser shot, you'll send it (and the droids) back to
its own dimension. But it's not an easy task. You
must first eliminate the droids who guard the
mothership. Each changes three times before be-
ing sent back home.

VIC Notes

Alien Armada has ten skill levels, (the easiest)
through 9 (the hardest). In levels 0-4, you have
six robots, and the birds move slowly. In levels

46 COMPUTED Gazette May 198S

Deadly smartbombs, slow bombs, and birds descend
continously (VIC version).

5-9, you have only three ships and the birds are
faster. Scoring is as follows:

smartbombs points (cannot be shot)

stow bombs 10 points

aliens 10 points

birds 100 points

mothership 2000-5000 points

If you reach 10,000 points, the aliens get angry
and the pace quickens.

Typing In The VIC Version

The VIC version runs without memory expan-
sion, but you'll need at least 8K memory expan-
sion to enter it. First, type in Program 1 (with or
without expansion) and save it. If you're using
tape, change line 460 to:

460 LOAD"AA",l,l:END

Program 2 requires VIC MLX (published
periodically in the GAZETTE). Follow these steps:

1. After saving Program 1, turn off the VIC and
insert the memory expansion (8K or more).

2. Enter POKE642,32:SYS58232.

3. Load and run MLX.

4. Enter a starting address of 4097, ending
address 7030.

A laser is fired at the rows of droids in hope of getting to
the mothership (64 version).

5. Type in Program 2 and save it with the
filename "AA". (If you're using a cassette drive,
be sure to save Program 2 immediately after Pro-
gram 1.)

6. After both programs are typed and saved, turn
off your VIC, remove the memory expansion,
load Program 1, then type RUN. It will automati-
cally load Program 2. Screen instructions will

prompt you when the program first appears on
your screen.

64 Notes

The 64 version contains some minor differences.
You must break through four rows of aliens
(there are three in the VIC version); levels 0-4
give you five lives (versus six in the VIC ver-
sion); and the high score is displayed. Also, the
64 version has a pause feature which is toggled
on and off with the SHIFT/LOCK key.
Scoring is as follows:

aliens 50 points

birds SO points

bombs 100 points

mothership 2000-5000 points

The 64 version is all machine language and
requires MLX to type it in. Follow these steps:

1. First, enter POKE642 / 20:SYS58260.

2. Load and run MLX.

3. Enter a starting address of 2049 and an ending
address of 4424.

4. After saving to tape or disk, turn the 64 off
and on (to reset some pointers). Load the pro-
gram and type RUN to start it. The joystick must
be in port 2.

How fast can you think? This challenging
game will put your brain to the test. It can
be played just for fun or in competition
with up to six players. Originally written
for the 64, we've added a version for the
VIC (at least 8K expansion required).

OK, the word is VEGETABLE. How many other
words can you make from VEGETABLE in less
than two minutes? Let's see, there's TABLE,
GET, BAT, and BALE, to name just a few.
"Charlemagne's Sword" is different every time
it's played. "Vegetable" is one of 30 words in the
program's vocabulary (but more can be easily
added). At the beginning of each game, you're
asked to choose the number of players, then
"Words" or "Dice." While "Words" selects one
of the 30 vocabulary words, "Dice" chooses nine
random letters, including at least two vowels.

The Longer, The Better

The longer your words, the more points you
earn. A good strategy is to quickly enter short,
more obvious words, like "no," "at," or "is,"
then hunt for longer words, like "table" or
"gavel" from our example above. When the
game begins, don't hesitate. Press RETURN after
each word is typed. Illegal letters (those not in

52 COMPUTEI's Gazette May 1965

the word or letters you're working from) are not
accepted.

But don't spend too much time thinking.
You have to watch the timer at the bottom of the
screen. When 12 seconds remain, the screen
flashes as a reminder that you need to hurry,

When the time is up, the screen prompts for
"Any Challenges (Y/N)?" If another player sus-
pects an illegal entry, the word in question must
be verified. (A dictionary or group consensus can
serve as arbitrator.) Press Y, then respond to the
prompt "Which Word?" by typing in the suspect
word. A prompt then asks if the challenge is cor-
rect. If so, the word is discounted. If not, another
prompt for challenges is offered. When all play-
ers are satisfied with the entries, a score is given.
Points are cumulative, so any number of rounds
can be played in one game.

If more than one player is involved, the pro-
gram cycles to the second player and so on.
Once through the cycle, the first player may start
another round or end the game by typing a back
arrow (a prompt is displayed to remind you of
this choice),

After several games, you may wish to add to
or replace new words in the program's vocabu-
lary. This can be done by changing the words in
the DATA statements at the end of the program.
If you add new words, the value of S$ in line 80
must reflect the new total, and the number 30 in
lines 90 and 780 (line 770, VIC version) must
also be changed accordingly.

1541 FLASH!—

m CRITICS SPEAK OUT

This advertisement has been written by indepen-
dent reviewers of Commodore computer products.
We thank them for their frankness and the high marks
awarded to the Skyles Electric Works 1541 FLASH!.

The Reviewers Comment

"Tired of that slow disk drive? The solution is here,
and it costs about S90. Considering what it does, the
price is a bargain! It speeds up your 1541 disk drive
2OO%-300%. And if you write your own software
specially for the FLASH!, you can achieve speed
increases of 600 % !

The 1541 FLASH! is the best! It's better than
KWIK LOAD." And better than 1541 Express.™

Does it sound too good to be true? Do you suspect
there must be some drawback that I haven't men-
tioned? Well . , .There is one. You have to open up
your keyboard and 1541 drive and do a little work
inside them. You need to replace a couple of chips
with new ones provided by the FLASH!. And an extra
cable will run from your keyboard's user port to your
1541 drive. But the installation is explained in
complete detail with pictures. It's a simple operation
that will take under 30 minutes. And in return you
will have a disk drive that literally races along!

The biggest complaint with the Commodore 64 is
the slow disk drive. No more! You will never be
willing to go back after having used the 1541 FLASH!.
It really spoils you! It's even faster than a parallel
drive with an IEEE interface! Don't be afraid of the
installation. It's really simple. And if you prefer not to
do it yourself, your local user's group probably has
people with the ability to install it for you. You'll be
glad you did!' Tfe Nor , hwest u$ers Gk ^ jm m5

"A tiny wedge is included . . . you simply SYS65526
to enable it. Those who enjoy using the wedge as part
of their normal computer will like this feature.

The utilities added by FLASH! include single,
double and simultaneous keystroke implementation
of such niceties as delete line, escape quote, cursor to
bottom of screen, 16 character tab, and return without
line execution.

My children have played some of their favorite
games and used utilities or educational software
without any problems whatsoever, using the 1541
FLASH! All in all, this device will save the purchaser
much of the frustration normally experienced, as well
as the time required in normal disk drive-computer
interactions. With the above noted exception, I'm
very pleased with its operation, and won't hesitate to
recommend it to those who would like faster loads
and saves or want additional flexibility and power at a
moderate price." RUN, May 1985

"Having used 1541 FLASH! for several days,
already I can't bear to go back to a slow 1541 . It's
amazing how quickly you can get spoiled by a luxury
like this. More than a few editors here have cast covet-
ous eyes on the upgraded 64/1541. And the price is
reasonable for such a dramatic enhancement. After
reading the installation description above, you can
decide if you 're up to opening your equipment, yank-
ing out chips, and enjoying a 300% speedup."

This player has nine words to his credit and a lot of time
remaining (VIC version).

If you find the games too uneven, with one
player winning too often, Charlemagne's Sword
can be modified. Line 100 gives 1.41 handicap-
ping points to each player. These points deter-
mine the score for each word using the formula
INT(1.41TJ), where J is the length of the word. A
four-letter word, for example, gives you three
points, while a five letter word is worth five. To
adjust the handicap for individual players, you
could add a line 105 HC(1)=1.51, which would

Longer words have earned more points for player 2 (64
version).

give player 1 a scoring advantage (a four-letter
word for player 1 would now score five points, a
five-letter word seven). Raising the handicap to
three would score a whopping 81 points for four
letters, 243 for five letters. Lowering it to one
means all words are worth one point, regardless
of length. Changing the handicap can make a
game between an adult and a child more of a
contest.

We'll pay for your mistake!

We know that it's difficult, especially since everyone
is trying to come out with one. Now that error track
protection is going the way of the dinasaour, you
probably purchased an obsolete piece of software. Well
we will give you $25.00 credirfor any original copy

"NEW REVISED CLONE MACHINE." Our program can
now back up non-standard sectors with complete con-
trol, detect and reproduce density-frequency alterations,
alter the number of sectors on a track, sync to particular
reference sectors (including a single sync Bit copy) PLUS
reformat a single track.

Other back up programs have only recently caught
up with our ability to reproduce errors. Included is Fast

Data File Handler Is a series of integrated programs that
give the user a database processor, a sequential data
file editor, and a disk operation support set. The book
consists of all the necessary program listings and docu-
mentation to use this powerful database management
system. Few computer programs are as well-explained or
as cost-effective as this one. Anyone who wants an
effective information management system for their Com-

ramming the Commodore 64:
The Definitive Guide

Raeto Collin West

Programming the Commodore 64 is an encyclopedic,
thorough reference guide to the Commodore 64. In the
tradition of the renowned Programming the PET/CBM, au-
thor Raeto Collin West has compiled 1 7 definitive chap-
ters which cover this computer in its entirety, There are
dictionaries, maps, BASIC and machine language exam-
ples, and programming aids. Unlike many computer
books, which can be read once and discarded. Program-
ming the 64 will remain valuable for the life of the com-
puter. It starts with BASIC and probes more deeply with
each chapter. Ready-to-type programs show how to use
the BASIC and Kemal ROMs; the 6502 microprocessor; the
CIA, VIC, and SID chips; and the hidden RAM beneath
the ROM in the 64. And major peripherals — tape and disk
drives, printers, plotters and modems— are also discussed

at length.

Jogger's Log

Ronald C. Pacanowski

This combination database and analysis
program will help manage and analyze
jogging records. Originally written for the
vTC-20 with 3K or more memory expan-
sion, we've added a version for the 64. A
disk drive is required.

If you're a jogger, you know that keeping track
of the time and distance of your runs helps mon-
itor your progress, nnd helps in setting new
goals. "Jogger's Log" is a database which does all
the recordkeeping for you.

If you're not a jogger, the program is written
in BASIC and can be easily modified to suit most
any endeavor where recordkeeping is an aid. The
following discussion will help in understanding
how the program is constructed.

A Menu-Driven Database

Data is stored on disk using random access fixed
length records of 256 bytes each. This means that
a disk will hold about 600 records. A sequential
index file is used to keep account of which tracks
and sectors have been used to store data.
Remember the advice of the disk drive manual
that a disk containing random access files should
never be validated.

The program begins by asking for the maxi-
mum number of runs you intend to enter. Then
the main menu appears. The menu options allow
you to create a new database, add a record (run)
to an existing database, modify or delete a record
in an existing database, or display the infor-
mation stored in the database.

Press the appropriate letter to select an op-
tion. (The menu fully appears the first time the

56 COMPUTE'S Gazetto May 1955

program is run. When you return to the menu
after your initial choice, you'll see CAMDSX.
This is an abbreviated menu, which is used to
save time. It corresponds to the original full-
screen menu. C creates a file, A adds a record, M
modifies a record, D deletes a record, S shows a
record, and X exits the program.)

Operation

Let's say you've decided to name the database
MY LOG and entered C to create it. You must
now enter data for run 1. The three mandatory
items are the date, distance, and elapsed time of
the run. Optionally, there is one category to de-
scribe the running route and another for any com-
ments you might make. It's important to enter
each in the correct form. The date must be ex-
actly six digits long, with the two digit month
followed by the two digit day, followed by the
last two digits of the year, The format is
MMDDYY. For instance, if the run was on Dec 9,
1984, the entry should be 120984.

Distance is recorded in miles, to the hun-
dredth of a mile. Time is expected to be exactly
six digits in the format HHMMSS, This means a
time of one hour, two minutes, and six seconds is
entered as 010206. Both the route and comments
categories must be less than 88 characters in
length (less than 80 characters in the 64 version).
Also avoid using commas in your route descrip-
tion or comments. Use dashes, periods, or other
characters acceptable to the INPUT statement. A
typical route might be: DOWN MAIN ST TO
EAST RD./UP THE HILL & BACK. The comment
field is useful for noting things like temperature,
humidity, pulse, starting time, type of run, etc. If
you don't care to add a route description or com-
ments, just press RETURN when prompted for
these entries.

After you've responded to the five cate-
gories, you're asked if there is data for another
run. The default is Y for yes. Press RETURN and
the input sequence repeats for the second run.
When finished, type N and the main menu
reappears.

To modify the data on a particular run, enter
M, the database name, and the run number. The
appropriate data will be brought onto the screen.
Following the new menu allows you to change
any or all categories for that particular run. When
you're finished making corrections, RETURN
takes you back to the main menu. Deleting a run
or adding runs to an existing database are done
similarly, by following the menus. Multiple
databases are also possible on the same disk as
long as each has a distinct name.

Now that you know how to create and
maintain a database, here's how to display its
contents. Enter S (for show) in the main menu.
This will bring up the selection menu. Here we
are relating a category (date, time, etc.), logical
operation (Equal, Less Than, etc.), and a value.
For example, suppose you wanted to consider
only those runs where the distance was greater
than 3.25 miles. Enter 2,GT,3.25. You are then
asked for another selection. If you enter
1,LT,011785, then all runs greater than 3.25
miles and before the date of January 17, 1985
will be considered. If we don't want to specify
any selectivity we just enter RETURN. The al-
lowed logical operations are: EQ (EQual), NE
(Not Equal), GT (Greater Than), LT (Less Than),
GE (Greater than or Equal), and LE (Less than or
Equal).

Next you are asked if you want a listing,
pace calculation, or a graph of the mileage. These
results will be displayed on the screen. (An op-
tion for printer output is not included but should
not be difficult to add.) The list, pace, and graph
options sift through the database and retrieve
only those runs which meet the previously speci-
fied selection criteria. You can page through the
listing by entering RETURN. This allows you to
easily review what information has been stored.

The pace option displays the mileage and
average pace. A 7:20 means a seven minute,
twenty second per mile pace. It also displays
weekly mileage and average weekly pace. After
every week the display stops until RETURN is
pressed. When using the graph option, you are
asked for some scaling information. The graph of
mileage is plotted by printing one line of as-
terisks across the screen for each run that was
specified. Each asterisk corresponds to a certain
amount of mileage, and days without runs are
noted by a zero followed by a blank line. Letting
one asterisk equal .5 miles works well for dis-

60 COMPUTEVs Gazette May 1985

tances up to around ten miles (when used with
the VIC's 22-column screen — 64 owners might
try .25 miles per asterisk). Again a RETURN will
continue the graph.

When a list, pace, or graph option is com-
pleted, the main menu will reappear. To exit the
program, use the X option. Note: Stopping the
program by using the RUN/STOP-RESTORE keys
anywhere but at the main menu may render your
database unreadable.

Suggestions To Users

After carefully typing the program in, save it, put
a newly formatted disk into the drive, and run
the program. The listing should be under-
standable with a little effort. Generous use of
subroutines is made to keep the program length
as minimal as possible. This also makes it easy to
lift out the database routines for use in other pro-
grams. When doing this, remember the fun-
damental restriction is that the records are fixed
at 256 bytes each. More categories can be added
as long as the total length of the record doesn't
exceed 256 characters. Sorting has not been in-
cluded here because it is natural to consider runs
chronologically. Adding a sort option is not diffi-
cult, but remember to sort the sequential index
file rather than the database itself.

SIMPLE ANSWERS TO COMMON QUESTIONS

Tom R. Halfhill, Staff Editor

Each month, COMPUTED GAZETTE tackles some
questions asked by new Commodore computer
users and by people shopping for their first
home computer.

a

I started out with a VIC-20 computer
and now have a Commodore 64. Recently I was
at a Commodore user group meeting and over-
heard a member talking about an "IEEE inter-
face" I've heard about many different kinds of
interfaces for Commodore computers, but I
never heard of this one. What's it for? Is it
something new?

x\m Actually, it's something old. It is known
formally as the IEEE- 488 interface (IEEE stands
for the Institute of Electrical and Electronic En-
gineers, and to reduce a mouthful to a bite-size,
IEEE-488 is pronounced "Eye tripie-E four
eighty-eight"). IEEE-488 is a standardized par-
allel interface often used in laboratories to hook
up computers with test instruments and other
electrical equipment.

The person you overheard at the Com-
modore meeting was probably an old-timer (in
personal computing terms, that is). The IEEE-488
interface dates back to the days of the Com-
modore PET, the computer which preceded the
VIC-20 and 64. First introduced in 1977, the
original PET had 8K of Random Access Memory,
a built-in monitor screen and tape drive, 40-
column screen format, and no color or sound (ex-
cept tones and beeps). It also had a built-in IEEE-
488 interface.

Why such an odd interface? Because the PET
was designed as a general-purpose personal com-
puter at a time when home computing was
still a dream. With an IEEE-488 port, it was
readily adapted to scientific and technical work.
Available for only $795 — an amazing value in
those days — the PET was an inexpensive way for
a company to computerize its equipment lab.
Electronic hobbyists, too, appreciated a computer

62 COMPUTE'S Gazette May 1985

with a standard interface that worked with their
sophisticated test instruments.

A couple of years later, Commodore began
using the IEEE-488 port as a floppy disk drive
interface (until then, the only mass storage de-
vice available was the cassette recorder). The
Commodore 2031, 2040, 4040, 8050, and 8250
drives all are designed to plug into the IEEE-488
port. Since the IEEE-488 is a parallel interface (it
transmits eight bits of information at a time), it's
actually much faster than the 1541 disk drive
interfaces found on the VIC and 64 (whose serial
interfaces transmit only one bit of information at
a time).

Some companies make add-on IEEE-488
interfaces for the Commodore 64 so you can
hook up disk drives made for the PET series
computers (including the high-density dual
drives). However, an IEEE-488 adapter that at-
taches to the 1541 serial interface won't deliver
much more speed than you'd get with a regular
1541 drive because the serial interface remains
the limiting factor. But if the adapter plugs into
the expansion port, it can provide a true parallel
interface and much faster disk access.

In addition, an IEEE-488 adapter lets you
connect a Commodore 64 to some special elec-
tronic equipment for scientific and technical
applications.

vd< J read about the new fast disk drive in-
troduced for the Commodore Plus/ 4 computer.
Is it really much faster than a J 541? And is
there any way to make it work ivith a VIC or
64?

£%m The new disk drive — which Commodore
announced last year as the SFS-481 and recently
renamed the 1551 — is indeed significantly faster
than the 1541. Why? For the same reason that an
IEEE-488 drive is faster than a 1541: It's a case of
parallel versus serial (see above). Besides the
usual serial interface found on the VIC and 64,
the Plus/4 also has a parallel interface specially
designed for the 1551. All other factors being

And, in effect, that's what you've done.

The new "S" series printers from Star
Micronics have been designed not to our spec-

found our accountants but will make great
sense to you.

These printers are faster than ever. More
compatible and reliable. With more added in

Because we've
increased our print-
ing throughput by
20%, you can now
finish 6 pages in the time it
used to take to print 5. And even though we've
upped our speed, we've kept up our quality

In fact, on three of our new models, both
draft and near-letter-quality are standard (no
extra charge). A fourth model, the SB-10, prints
draft and letter-guaJity standard (again, not
extra).

So now, with just one printer, you're ready
for data processing and word processing. ^
That's like owning two printers for the price
of just one.

The new Star "S" series
printers are fully compatible
with even the most fickle of
personal computers.

And they're especially
friendly with IBM 9 -PC, Apple?
Commodore? and all compatibles.

In most cases, hooking up is no more
complicated than putting a square peg in a
square hole. But it's a lot more rewarding.

READY FOR
ANY SOFTWARE

The new "S" series
printers make printing
as easy as 1-2-3."
Which is just one
example of the many
spreadsheet programs
they're ready for.

The new Stars can work
with word processing programs
like WordStar® Educational software
like Dr. Logo.™ And even the new integrated
formats like Framework'" and Symphony,'"

So Star printers match hardware to software
without disk-driving you crazy.

They handle many functions faster. They're
more compatible. Less expensive. More reli-
able. And have a full year warranty. "S" series
printers have been designed with so many of
your needs in mind, it's as if you'd done it
yourself.

And what a great job you did.

equal, a parallel interface can send and receive
data up to eight times faster than its serial
counterpart.

At this writing, production models of the
1551 are not yet available, so we haven't tested
the new drive to see exactly /iou' fast it is. How-
ever, we have used prototypes at computer trade
shows and observed that they are noticeably
faster than 1541s.

Although the 1551 is not compatible with
the serial interface on the VIC or 64, it's possible
that Commodore or another company could
build an adapter to connect the new drive to the
expansion port. Like the IEEE-488 adapter de-
scribed above, a 1551 adapter could add parallel-
speed disk access to existing VICs and 64s.

vln Some TV sets coming out lately have
audio and video input jacks on the back. The
advertisements claim these TVs can be used as
computer monitors. Are they really as good as a
real computer monitor?

ili They're very close. Simply speaking, the
video input jack bypasses the TV tuner circuitry
and feeds the incoming video signal directly to
the picture tube. (The jack can accept video sig-
nals from a home computer, a videogame ma-
chine, a videocassette recorder, or a videodisc

player.) Bypassing the tuner circuitry nearly al-
ways results in a much sharper image than when
the computer is connected to the antenna
terminals.

Here's why: When you hook up a computer
to antenna terminals, the TV is expecting to re-
ceive a signal which resembles a normal broad-
cast transmission. So the computer simulates a
broadcast by converting its pure video signal
with a device called an RF (radio frequency)
modulator. When the TV receives the RF-
modulated output through its antenna connec-
tions, it treats the signal like a regular broadcast.
The TV tuner section converts the signal back
into the original video and feeds it to the picture
tube. Inevitably, some quality is lost during this
double conversion process — a process that is
eliminated when you tap into a TV's video input
jack.

Because the circuitry of a computer monitor
can be optimized in various ways for computer
use, it's still superior to a TV set with video in-
puts. In practice, however, the difference may
not be too noticeable. One exception is when a
Commodore 64 (or Atari 800) is hooked up to
the rear connections of a Commodore 1701/1702
monitor. By separating certain parts of the video
signal, this arrangement produces an extremely
sharp image that is pretty hard to beat. @

The Cosmic Balance

"Captain, a Brotherhood dread-
nought approaches us at 32 de-
grees. They've launched a plasma
torpedo. What are your orders?"
"We'll meet them head on.
Bump velocity to six and ivait a
couple of seconds before changing
bearing to 33. Energize all belts,
full power to shields. Arm weap-
ons, fire at optimum time. Launch
a fighter group. Hold it — on sec-
ond thought, cancel the fighters. If
we smash their shields, send a
boarding party of marines. Maybe
we can capture their ship without
much of a fight."

In this game for the 64
from Strategic Simulations Inc.
(SSI), you control one or more
starships in tactical combat
against enemy vessels. The
many options may seem daunt-
ing at first, but as you gain
experience in battle, you learn
to appreciate the subtleties of
The Cosmic Balance.

First, you choose either to
start a new game or to recall
one you've saved to disk. You
can opt for two players or one
(you against the computer, with
four difficulty levels). Finally,
you choose which of the six sce-
narios you'll play.

Some scenarios are simpler
than others, and can be played
fairly quickly (30-60 minutes).
Others take time, especially if
you have to keep track of sev-
eral ships. Each game has its

own victory conditions, goals
you must attempt to reach. In
five of the six scenarios, you
have to build ships from scratch
(or recall a previously built ship
from disk).

Choose a technology level
and a ship size (from the tiny
Corvette to the huge Dread-
nought). You're tempted at first
to build vessels with lots of fire-
power. But in practice, a heavily
armed ship with no defense is a
sitdng duck.

You begin with a shell and
a limited amount of space for
offensive and defensive weap-
ons. There are a few necessities
you should install first: engines
(for power), drives (for moving
the ship), and defensive shields.

If you give your crew extra
room for eating, sleeping, and
living, they'll be happier. Hull
space translates to crew effi-
ciency, although it means you
have less space for things like
weapons, drives, and engines.

Six different weapons are
available: light phasers, heavy
phasers, siege phasers, photon
torpedoes, disruptors, and
plasma torpedoes. There are
also several guided missiles:
light seekers, heavy seekers, and
fighter groups. Fighter groups
take up much space. But they
swarm like bees and cause lots
of damage. Other items include
range (warp drives), cargo holds
(required in certain scenarios),
marines and transporters, armor,
belts, and tractor beams.

When you're finished creat-
ing ships, you can save them to
disk.

Now the battle begins. Each
turn has two parts: Orders and
Execution. In the Orders phase
you can change speed or bear-
ing, arm and fire weapons,
launch guided missiles, repair
shields, jam their radar, send a
boarding party of marines, and
much more. Two high-resolution
maps allow you to plot your
course and identify other ships
in the sector.

As the game proceeds and
your ship is battered by phasers,
torpedoes, and guided missiles,
you may find yourself losing en-
gines and running out of en-
ergy. As a last resort, you can
drain energy from the shields.
This weakens your defense, but
gives you power for weapons
and drives.

After all orders are given,
the execution phase begins. The
ships fly around the screen,
launching different types of
weapons. If a weapon hits,
you're told how much damage
occurred.

You then go on to the next
round, giving more orders and
watching the results. Some
games end after ten turns; oth-
ers have no time limit. If you're
losing and have some warp
drives (range) remaining, you
can warp out, ending the game.
You then learn who won the
battle.

Letter-Go-Round

A lot of educational programs
for preschoolers are cumber-
some or presume too much of
the child. Some, which are oth-
erwise good, are too slow —
unappealing to an age group in
which the attention span is
short. But as more educational
software for the Commodore 64
has developed over the past
year, the parent or teacher has
more and better choices.

Letter-Go-Round, developed
by the Children's Television
Workshop and published by
CBS Software, is an outstanding
choice for teaching early reading
skills. It's also highly entertain-
ing. Featuring five famous Ses-
ame Street characters (Big Bird,
Bert, Cookie Monster, Barkley,
and Grover), the program is de-
signed for children ages three to
six. The package includes
"EasyKey," a vinyl (easy to
clean) keyboard overlay which
simplifies matters for the child.

The program offers six lev-
els which collectively teach let-
ter recognition and matching,
upper- and lowercase matching,
word recognition, and simple
spelling. The screen scenario, an
appealing high-resolution ren-
dering of a circus, is the same
for all levels. At the center is
the "letter-go-round," which
looks like a ferris wheel. At
each level, one of the Sesame

Street characters (selected by the
child) brings out the props — for
example, Cookie Monster might
bring out B, A, and a blank. The
letter-go-round, containing per-
haps a J, D, W, T, S, or X, spins,
and when an appropriate letter
(D or T is acceptable in this ex-
ample) reaches the bottom,
STOP on the overlay is pressed
to halt the ferris wheel and drop
the letter into place. After a cor-
rect answer, a segment of the
"strength -o-meter" (a tower
with a bell on top) is built. Then
the Sesame Street character re-
turns to a tent and brings out a
new set of props. After the
tower is complete, the strength-
o-meter bell is rung and Big
Bird, Bert, and Cookie Monster
come out and dance a little jig
to some delightful music, thus
ending play on that level. A
new level may then be selected.

A number of thoughtful ex-
tras have been added to give the
program more value as an edu-
cational tool. On the overlay,
the pictures of a rabbit and tur-
tle can be pressed for a fast or
slow ferris wheel. A Pause but-
ton is included here also. The
levels on the main menu range
from easy (Upper Case Match-
ing) to hard (Spell the Secret
Word), but by pushing the Level
button, you can select any one.

There are no penalties for
wrong key presses or choices. If

Ritemcm R 64 and
C+ Dot-Matrix
Printers

The Riteman family of printers
has entered the fray, jumping in
amidst the numerous companies
trying to capitalize on the low-
cost printer market. Riteman's
models include a built-in Com-
modore serial interface; you
don't need to buy a special in-
terface cartridge. They also offer
full MPS-801/1525 compatibil-
ity. That means that you can
run programs written for the
MPS- 801 printer, yet take ad-
vantage of the extra speed and
bonus features of these printers.

The Riteman R 64 is the
more expensive printer. It's
quite attractive, looking like a
slenderized and streamlined
Epson MX-80. A special tiny
ribbon cartridge is used, and the
printer can feed either pinfeed

or single-sheet paper. It prints
bidirectionally at 120 characters
per second. Epson MX-80-
compatible printing modes in-
clude double strike, emphasized,
compressed, underlining, super-
and subscripts, italics, double-
width, and high-density graph-
ics mode. It can print either 40,
66, 80, or 132 characters per
line. The characters are well-
formed within a 9 X 9 matrix,
with full lowercase descenders.
The built-in Commodore inter-
face adds the full set of Com-
modore graphics, true
reverse-field printing, listing
mode (where cursor and color
controls are spelled out) and
MPS-801 features like pro-
grammable tab stops. A bonus:

The Riteman R 64 also includes
a Centronics parallel interface,
so you can use this printer with
other computers, such as the
Apple, Atari, and IBM PC, and
it should work with the next
computer you buy, provided it
has a Centronics parallel printer
interface.

The Riteman C+ printer
shares most of the features of
the R 64, except for listing
mode. It works only with the
Commodore serial port, lacking

the additional Centronics paral-
lel interface. It also prints at a
more modest 105 characters per
second. This printer is unusual,
though, because of its front-
loading feature. You feed the
paper through the front of the
printer. The paper stays flat and
is printed on by a vertical
printhead. This unique design
lets you print at the very top of
a sheet of paper, and eliminates
many paper-feed problems. Be-
cause the paper does not have
to be wrapped around a platen,
this printer can print on heavy

posts so that you can store the
paper conveniently underneath.
However, the C+ uses a some-
what unwieldy ribbon, with the
ribbon exposed and stretched
between two small modules. It's
hard to install the ribbon with-

out smudging a bit of it on your
hands.

Both printers are a good
value for the price, delivering
most of the features shoppers
look for in a dot-matrix printer.
Although the print is not letter

Monty Plays
Scrabble

Few board games have proven
as broadly popular and endur-
ing as Selehow & Righter's
Scrabble. Even in an era of fast-
action arcade games with daz-
zling graphics, the classic
crossword game continues to
attract— and addict — hosts of
players.

Now, in its thirty-seventh
year of distribution, Scrabble is
available for the 64. Called
Monty Plays Scrabble, this pro-
gram pits you against a com-
puter opponent, Monty, and up
to four other players. With a
vocabulary of over 12,000
words, Monty is a worthy oppo-
nent to all but the more ad-
vanced Scrabble players.

The traditional playing
board is faithfully rendered on
screen, with pink, light blue,
dark blue, and red premium
squares. Your tiles are displayed
below; a menu of options ap-
pears on the right. In addition
to the established playing
choices in Scrabble — such as ex-
changing tiles or passing — the
menu includes such options as
Juggle (to rearrange the tiles on
your rack); Hint (which suggests
a playable word); and Swap

(which allows you to take over
Monty's hand).

The program is easy to fol-
low and comes with a complete
set of instructions. You can
choose to play against Monty,
or you can watch Monty play
against himself. And you can
elect to watch Monty "think" —
that is, you can see Monty's
word choices and their scores as
the computer searches for the
most valuable word.

Like the board game, Monty
Plays Scrabble can be a useful
learning tool for younger play-
ers. The program is friendly and
encouraging, offering messages
of "Well Done!" or "Good
Choice!" when a word is se-
lected. And, in the process of
watching Monty "think," the
player becomes involved in
working out every viable com-
bination of letters along with
Monty.

There are a few minor
drawbacks, though. While the
program checks Monty's words
against a dictionary, it won't
check the validity of the players'
words. Since Monty won't
"challenge" you, players will
not be corrected if they use bo-

' ',* JiaiSlsnJ in

gus or misspelled words. Also, it
isn't possible to play only
against another person — Monty
deals himself in for every hand.
And finally, because of the vol-
ume of possible letter combina-
tions which must be checked at
each turn, Monty may take sev-
eral minutes to complete his
turn, especially in the later
stages of the game.

Monty Plays Scrabble is a
welcome game for Scrabble afi-
cionados who want a tireless
partner, children who need a
jostle-proof playing board, or
teachers and parents who want
a novel approach to vocabulary
building.

Real World Software

Part 1 : A Bright New Trend In Home Computing

Fred D'Ignazio, Associate Editor

VisiCalc For The Home?

I recently returned from Las Vegas, where I cov-
ered the Winter Consumer Electronics Show
(CES) for The Neiv Tech Times, a national public
TV program on consumer electronics. Based on
what I saw, this is my verdict:

The home-computer industry is at its lowest
point in years. Home computers are no longer
the "in" thing to buy. They have been replaced
by VCRs, compact discs, pocket TVs, and other
glamorous newcomers to the consumer electron-
ics industry. As a result, hardware and software
companies have gone out of business, computer
magazines have shrunk for lack of advertisers,
and Wall Street investors and the national news
media have lost interest and are looking else-
where for what is new and hot.

Some observers have equated home comput-
ers with videogames and hoola hoops, and have
predicted the demise of the home-computer in-

Fred D'Ignazio is an associate editor of COMPUTE! and

The New Tech Times, a national public TV program ots

dustry. But I think this assessment is too gloomy.
I don't believe we're at the end of the home
computer revolution, we're only in a trough.

What will get us out of that trough?

A new generation of even lower-priced, even
more powerful computers, like Atari's new ST
series and Commodore's Amiga, will give the in-
dustry a tremendous boost. But fancy new
computers are not the only way to revive this in-
dustry. We also need new kinds of software —
programs that are so exciting, low-cost, and prac-
tical that they will motivate people to buy a new
computer just so they can run the software.

What kind of software should we look for?
Some observers are on the lookout for a
"VisiCalc of the home"- — a product so unique
and powerful that, single-handedly, it will an-
swer the consumer's still nagging question, "Why
do I need a home computer?"

I think it's unlikely that a single program
will emerge and provide a compelling justifica-
tion for buying a home computer. Home com-
puter users are too diverse a group, and homes
are too complex and heterogeneous for a single
product to answer everyone's needs. Instead, I
think that we should look for a whole new genre
of home software that thrusts the computer into
the real world. I see such a genre now on the
horizon, a genre I call real world software.

What Does It Feel Like?

This month and next I'll describe, define, and
give examples of what I mean by real world soft-
ware. But these are just words. The ultimate test

You never know who you will meet
or what will be said when you're on
American People/Link.

AMERICAN PEOPLE/LINK™ users meet a lot of
different people. That's because PEOPLE/LINK— the
nation's first all entertainment videotex
network — allows anyone with a word processor,
personal computer or terminal, and a modem to
communicate with other users throughout the country
from the privacy of their own homes.

Sometimes these electronic conversations are
serious... sometimes they're outrageous... but they will
always keep your interest as you talk to friends and
make new ones. PEOPLE/LINK's recreational programs
include:

PARTYLINE — Meet people and talk live with other
PEOPLE/LINK members throughout the country in
groups or privately.

CLUB-LINK — Join or start a club or group devoted to
a favorite hobby, rock group, lifestyle, etc.

WHO-IS-WHO — locate other users with similar interests.
And there's much more with programs like NETMAIL,
our person-to-person electronic mail, PEOPLESCAN,
the national bulletin board system, and play games such
as poker, blackjack, checkers, chess, backgammon, and
bridge (color graphics are available for most popular
computers).

And the greatest thing is that you don't have to be a
computer whiz or even know how to type to use
PEOPLE/LINK... just be smart enough to subscribe nowl

AMERICAN

PEOPLE

is to try the software out and see how the soft-
ware feels to you. You'll recognize real world
software when you come in contact with it. And
it will mean something different to each person
who experiences it.

As I prepared this column, I spoke to many
different people in the software industry. When I
told them I was writing an article about "real
world software," the amazing thing was that
they immediately knew what I meant, even
before I tried to define it or describe it. And they
began telling me what real world software meant
to them and what examples they had seen
recently.

One person I spoke to had this reaction:
"Real world software. Kitchen sinkzvare. Stuff that
you keep around the house like a bottle of glue,
a flashlight, or a screwdriver. You never know
when you'll need it. But you will."

When I told my assistant, Kim Harris, about
real world software, she thought of her boy-
friend, Robert Ruff. "Robert is working on a
construction crew," she told me, "building a new
shopping mall. He's so happy because he's learn-
ing valuable things about architecture, electron-
ics, and engineering. He'd rather learn this way
than study books in a classroom. Maybe that's
what real world software is. It's on-the-job train-
ing, the kind that Robert likes."

When I mentioned real world software to
Jeff Clarke, executive producer of The New Tech
Times, he too instantly recognized it. "It's like the
high-tech stress cards we're giving out at CES,"
he said. "The cards tell you whether you're re-
laxed or tense, and, if you are tense, they give
you simple techniques you can use to relax. The
cards are like your "real-world" software should
be. They are simple to use, and they give im-
mediate, personally meaningful information and
results."

What Should It Do?

Based on the comments above, defining real
world software is easy. It's easy-to-use software
that gives an immediate, direct, visible benefit to
a person in his or her daily life.

As I see it, real world software is really self-
improvement software. It gives you the skills you
need to tackle all areas in your life more cre-
atively and effectively.

When I talked to John Paulson, president of
Springboard Software, he warmed immediately
to the idea of real world software. "That's just
what we need," he said. "With real world soft-
ware the computer will beckon, teach, work for
you as a tool, then send you out armed and eager
into the real world to apply the skills you have
learned."
94 cOMPUTErs Gazette May 1955

How Does It Work?

The goal of real world software is to be a self-
teaching tool. To do this effectively, it needs to
weave together several key elements, including a
knowledge database, skill in applying that
knowledge base to real life, and a playful ap-
proach that makes it fun to learn the knowledge
and apply the skill.

Real world software must be a powerful
tool. But it must also teach us how to use the
tool, give us practice in applying the tool, and
thrust us into real-life situations in which we get
to use the tool and improve our technique, Last,
it must suggest applications in the real world
where we can apply the tool after we have left
the computer.

What features should real world software
have? First, it should be simple to learn and sim-
ple to use. It must be immediately accessible to a
child or a beginner of any age.

Beyond that, it must be playful, charming,
and appealing to young and old alike. As John
Paulson put it, the software must beckon. It
makes learning a new skill a thrill, not a chore.

The program should also let a person get
right to the action. The mechanics of the pro-
gram should be so easy to master that a person
can go immediately beyond the program to the
knowledge areas, skills, and applications the pro-
gram teaches.

On the other hand, the program should not
be a black box, blocking the naive user from its
power; or a child's toy that has no relevance out-
side a toy world.

Rather, it should be at once simple yet
powerful. The rules for using it should be intu-
itively obvious. As the person uses it, he or she
should become more adept at using it further.
The program should let a person learn on the job.

Third, there should be a strong factual basis
to the knowledge that the program imparts. Real
world software is really expert software that
everyone can use.

Fourth, the program should use the latest
ideas in program design, including icons (pictures
representing information or courses of action);
contextual help screens; on-screen menus or pull-
down menus; and a choice of mouse, joyboard,
or keyboard control (or a user-determined mix of
all three).

This is a controversial area with lots of
conflicting opinions. As Marc Canter, president
of MacroMind (developer of the Macintosh
MusicWorks and VideoWorks programs from Hay-
den Software) says, "The world is divided into
two camps: people who type in commands and
people who don't; people who memorize com-
mands and people who don't." Canter is one of
those people who doesn't like to memorize or

type in commands and says, "I never want to go
back." Then there is Richard Mansfield, senior
editor of COMPUTE! Publications, who wrote in
the February 1985 issue of COMPUTE!, "It's far
easier, for many people, to simply type LOAD
'PROGRAM' than it is to move a mouse to a
menu, pull down the disk menu, move to the
program name, move the mouse up to the word
LOAD, etc."

Canter is in one camp, Mansfield in the
other. This is why people should have a choice in
the way they interact with a real world program.
And they should be able to customize their own
means of interaction.

Next, a real world program should contain
several discrete modes, including introductions to
the tool, knowledge area, and skill in using the
tool; an online tutorial; challenging real-life
scenarios for practice; and the actual tool .itself
once the user is ready to get down to business.

The actual tool should have shades and
gradations beginning with novice and ending
with expert. The software should enable each
person to use the tool unconsciously at his or her
level of confidence and expertise.

The software should be powerful enough to
be attractive to experts; but, more importantly, it
should offer the beginner a step-by-step ap-
proach to learning a new skill, with numerous
opportunities to practice the skill and get im-
mediate, constructive feedback.

Sixth, real world software should come with
a substantial users manual. The manual
shouldn't waste time explaining the software; the
software itself will take care of this. Instead, it
should be a practical yet literate introduction to
the knowledge embodied in the software, and a
checklist of the powerful ideas and techniques
embedded in the tool. It should also be an idea
book full of suggestions and activities a person
can do with the software.

Seventh, the software should be supple-
mented with additional, lower-cost software
packages with databases, templates, and other
supplies that help personalize the software for
different users and introduce users to different
subjects. It should also, of course, let users enter
their own databases.

Eighth, the software should have easy-to-use
recordkeeping features that enable a child, par-
ent, or teacher to monitor a learner's progress as
part of the software's hidden curriculum in a
particular discipline or domain of knowledge.

Ninth, the program should place great
emphasis on on-the-job, practical training in the
context of an adventure, a mission, or a story. A
person should be given real-life situations, goals,
and challenges. Mastery of the skill should per-
mit them to meet these goals and overcome these

challenges. Then the software should rush them
out the door and urge them to apply the skill im-
mediately in the real world.

On-the-job training, realTife situations, and
immediate transfer to the person's daily life are
the key features. The program should combine
the cerebral, bookish world of the ivory tower
with the do-or-die immediacy of the space shut-
tle cockpit, the scientist's lab, the executive's
hotseat, or the ditchdigger's muddy hole. The
force of intellect in all human advances is de-
rived from a blend of the practical and the ab-
stract. Real world software can merge these two
components of knowledge into powerful and
beneficial learning programs for home computer

users.

Examples Of Reed World
Software

Have I whetted your appetite for some examples
of real world software? If I have, good! Next
month I'll give you 106 examples of real world
software in 24 different areas of knowledge,
including skills in medicine, college studies,
communication, crafts, dance, diet and nutrition,
exercise, map reading, inventing, math, money
management, music, organization, outer space,
relating to other people, running a newspaper,
predicting the weather, and designing bridges
and buildings.

After I give these examples, I'll tell you my
wish list for real world software on Commodore
computers in the future. And I'll ask you, the
reader, what real world software you've seen and
what you'd like to see.

Stay tuned. I'll be back next month!

How To Recognize
Real World Software

Real world software should:

* Be simple to learn and use * Appeal to
all ages * Be playful and charming * Not
force you to learn or remember elaborate
commands * Get you right to the action *
Have a strong factual basis * Be accompa-
nied by a substantial printed introduction
to the skill or subject it teaches * Offer
supplementary templates, databases, sup-
plies, etc, * Offer powerful yet simple
recordkeeping features to let you monitor
your progress * Give you on-the-job,
practical training in real-world skills *
Encourage you to apply your new skills
immediately in your daily life * q$

The Hush 80 CD Printer

We're not through with printers yet. Lately, doz-
ens of manufacturers have flooded the market
with low-cost, Commodore-compatible printers
and printer interfaces. Since printers are one of
the most popular peripherals after disk drives,
we'll continue to bring you the latest information
on this burgeoning business.

Thermal printers are an important part of the
printer market. Although they sometimes pale in
comparison to impact dot-matrix printers, they
are unique in their low cost, high reliability, and
low operating noise level. The Hush-80 scores
high in these categories. It is an extremely attrac-
tive printer for the price, only $139.99. It prints
on special thermal paper, which we've discussed
in previous columns.

A thermal printer is very quiet compared to
the racket of an impact printer. You can barely
hear the Hush 80 print, the sound of the
printhead brushing across the paper. The loudest
sound is the faint grinding of the paper feed. You
can press a small button to feed the paper one
line, or hold it down to feed at high speed (al-
though it sounds like an overworked sewing ma-
chine at this rate). You can hold down the button
while you power-up the printer to print out a
self-test.

It appears that manufacturers know what we
want in a printer- — full Commodore compatibil-
ity. That way everyone can use the same soft-
ware without that software having to customize
itself for your particular brand of printer. The
Hush 80 CD has a built-in printer interface, so
you don't need to buy one. It lets the printer dis-
play the full Commodore character set, including
all graphics characters and reverse-video. The
characters look like your average dot-matrix
character set, not much like letter quality, but

The Hush 80 CD Printer

still quite readable. The printer is not slow, print-
ing in both directions at 80 characters per sec-
ond, although the actual printing speed is slower
since it takes a little longer to feed the paper
than on other printers.

The Hush 80 CD supports all the special fea-
tures of the MPS-801 and 1525 printers, includ-
ing graphics mode, double- width characters, and
programmable tab settings. We've tried it with
SpeedScript and some screen-dump software and
had no problems. The only rule it doesn't follow
is that reverse-field should automatically ter-
minate at the end of a line. The Hush 80 stays in
reverse-field mode until you send reverse-off. No
big problem, unless you print a disk directory.
You can edit out the reverse field if you LOAD
"$",8 before printing the directory.

801 Printer

802 Printer

803 Printer

This is a really small printer, smaller in size
and length than a carton of cigarettes, and
weighing only 25 ounces. The roll paper installs
inside the printer, further making this a compact
machine. In fact, I've set the printer up on top of
the 1701 monitor, using no desk space at all. The
disadvantage of thermal roll paper is clear. The
thermal paper is rather glossy, and tends to
darken as it ages (although it photocopies well).
The roll paper makes word processing a little
cumbersome. You have to manually tear off each
sheet you print. For casual use or for printing
program listings, though, roll paper is just fine.

The Hush 80 comes in several other
configurations, either parallel or serial, with an
optional battery pack. You could buy the Hush
80 with the Centronics parallel interface, then
buy a parallel interface, and also use the printer
with any computer with a Centronics interface.
The serial version is for computers with an RS-
232C serial interface. An optional rechargeable
battery pack, which lasts 100,000 characters per
charge, makes this an ideal printer for portable
computers.

Three Printer Interfaces

Three new printer interfaces have arrived for
evaluation since J. Blake Lambert's feature,
"Selecting A Printer Interface" (August 1984). If
you're looking for an interface for your non-
Commodore printer, you might consider one of
the following models. (Also, look for more
printer interface information in the upcoming
July GAZETTE.) All work with either the VIC or
64. Since the Plus/4 and Commodore 16 have
redesigned cassette ports, the power required
from the cassette port for most of these interfaces
is not available.

MW-350

This rather large interface attaches like most
Commodore interfaces. A round plug for the se-
rial port attaches to either your computer or disk
drive. You plug the printer cable from the inter-
face into the Centronics port on the printer.
(None of these interfaces can be used with an
RS-232C serial printer.) The MW-350 attempts to
draw the power needed to drive the interface
from pin 18 on the printer. Not all printers sup-
ply the necessary voltage, though, so Micro World
Electronix sells an optional power plug that plugs
into the cassette port on the back of the com-
puter. The cassette plug duplicates the cassette
bus, so you can still use a tape drive.

This interface seems solidly built, with a
metal serial port plug that snaps into place better
than any plastic one I've seen. In emulation
mode, the MW-350 simulates the features of the

98 COMPUTERS Gazette May 1985

MPS-801 or 1525 printer. Since the MW-350 is a
graphics interface, it uses the graphics mode of
your printer to reproduce Commodore graphics
and cursor symbols, The emulation mode honors
all 1525/MPS-801 secondary addresses and com-
mands for double width, graphic mode, tab
stops, etc. It also reproduces reverse- field charac-
ters. A small set of switches is used to customize
the interface for your printer, supporting most
popular parallel printers. A listing mode trans-
lates the cryptic symbols used on the screen for
cursor controls into readable words, similar to
the GAZETTE'S listing conventions. A transparent
mode lets you send all codes directly to the
printer without any translation between Com-
modore ASCII and true ASCII. Other printer
codes specific to this interface let you set the left
and right margin and forms length, and lock in
any secondary address. By simply opening the
case and plugging in RAM chips, you can add a
2K or 4K printer buffer.

What sets this interface apart is the excellent
interface manual, written with the novice in
mind. Although it will still require careful study,
any casual computer user can easily get his
printer working with a wide variety of software.
If you're a programmer, there is detailed infor-
mation on how to bypass the emulation mode
and communicate directly with the printer. The
manual is full of charts, figures, and pictures,
though it lacks an index. My only complaint is
that the manual is printed in light green on
white. Pretty soon you begin to see red after-
images fluttering about the page.

Cardco Card/? B

One of the first printer interfaces for the VIC and
64, Cardco's Card/? (pronounced card-print)
continues to evolve. The latest revision shrinks
the electronics down to a large plug that fits di-
rectly into the printer. A cable connects to the
computer's serial port, and a thin wire attaches to
a cassette port module, removing any doubt
about power availability.

This latest revision improves on MPS-
801/1525 compatibility. Earlier models would
not always transparently work with software de-
signed for the MPS-801/ 1525. The Card/? B of-
fers a listing mode where cursor controls are
translated into words like [CLEAR], However, the
Card/? B does not offer graphics emulation, so it
seems more useful as a lower cost alternative
interface for printers lacking a graphics mode,
including letter quality printers. A lockable
transparent mode lets you use the Card/? B as a
"dumb" interface. In transparent mode (some-
times called graphics mode), the interface only
performs the serial-to-parallel conversion, and

does not interpret, intercept, or translate charac-
ters coming in. A transparent mode is required
for certain word processors and graphics dump
programs,

Cardco's manuals also keep improving, with
expanded tutorials on BASIC printer program-
ming, and tips for use with various "printers. Sev-
eral sample programs illustrate the features of the
interface, including some utility programs for a
screen dump and simulation of Commodore
graphics characters.

TurboPrint/GT

It's hard to distinguish this interface's features
from the others, but an optional 16K or 32K
"TurboBuffer" makes this an extremely powerful
model. Like the MW-350, the TurboPrint/GT is a
graphics interface that works with most popular
parallel printers. It can reproduce Commodore
graphics and reverse video, and also offers a list-
ing mode. However, this model does not
transparently emulate the MPS-801 or 1525. It
supports all the same codes and functions as the
MPS-801/1525, but the same, secondary ad-
dresses are not used. It has a lock mode that lets
you force the interface to remain in a particular
mode. The manual is not as tutorial or as read-
able as the other two interface manuals reviewed
here, but does include a listing of a graphics
screen dump program for the 64.

With the TurboBuffer, you can dump your
text to the printer with no waiting. The buffer
stores the text coming from the computer, then
feeds it out to the printer. If you don't fill up the
buffer, you can continue to use your computer
while the printer chugs away.

The Hidden Magic
Of String Functions

This month, we'll reveal some real magicians'
secrets — five unusual commands which are ex-
tremely important in BASIC programming, but
which are seldom explained, even in reference
guides. These commands are called string func-
tions. They include: RIGHTS, LEFTS, MID$,
STR$, and LEN.

Using String Commands

Examples to try:

LEFTS (two symbols from left) A$="ABC":PRINT LEFT$(A$,2>

RIGHTS (two symbols from right) AS "ABC":PRINT RIGHT$(A$,2)

MIDS (position 2, one character) A$ = "ABC":PRINT MID$(A$,2,1)

MID$ (random from string) AS- "ABC":PRINT

MID$(A$,INT(RND<1)*3» + 1,1)

LEN (length of string) A$ = "ABCDE":PRINT LEN(A$)

STR$ (remove leading space) A = 17:A$=MID$<STR$(A),2):PRINT"$"A$

STR$ (numeric to string variable) A = 17:A$=STR$(A):PRINT AS

STRS (add zeros to numbers) A = 17:PRINT STR$(A) + ".00"

ables causes the computer to display the result of
the calculation.

String variables are used to abbreviate and
manipulate string information — including words
and letters, punctuation marks, graphics, colors,
editing commands, and numbers not used in
calculations. A string variable can be used to de-
fine any information which can
normally be printed inside
quotation marks. Here's a simple
example (include one blank space
after the S in COMPUTERS):

cs='

ETTE" :PRINTC$+ G$

A Quick Review Of Variables

As you may recall from previous columns, there
are two types of variables: numeric and string.
Variables are short abbreviations used to stand
for numbers, words, graphics, and other
information.

Numeric variables are used to stand for
numbers used in calculations and program com-
mands. A numeric variable can be a letter
(A,B,C) or a letter and another letter or number
(A1,B3,X4,ZZ,CP). Here's a short program that
defines the variable Al as the number 10 and the
variable A2 as the number 20, then adds them
together and prints the result:

10 A1=10:A2=20:PRINT A1+A2

Type RUN and press RETURN. Using the
PRINT command to add together the two vari-

100 COMPUTE!* Gazette May 1985

Type RUN and press
RETURN. Here, we define the
string variable C$ as the word
"COMPUTERS " and the vari-
able G$ as "GAZETTE". We can
add two or more string variables
using a PRINT command and a
plus sign ( + ). It's not really adding in the way
numbers are added, so using a plus sign between
strings is called "concatenation." Concatenating
string variables has the effect of printing them
side by side.

String variables have many uses, tor ex-
ample, here's a handy way to print lines on the
screen (use 22 instead of 40 if you have a VIC):

10 G?='

20 PRINTG$

There are many other ways to manipulate
strings of information. Before we get into the
individual string functions, here's a teaser:

How did we do that? Read on.

Using LEFT$ And RIGHT$

LEFTS and RIGHTS allow you to pick out parts
of a string from the left or right side of the string,
and print or manipulate the information. To
show you how this works, let's create a variable
in direct mode (just type it directly into your
computer — the computer will hold the variable
in its memory):

Y$ = "YESNO"

Now, you can use either LEFTS or RIGHTS to
print all or part of this variable. Both commands
work similarly. Type this command:

PRINT LEFT$(Y$,3)

The computer displays the word YES because the
LEFTS command tells the computer to print the
leftmost three characters from the string variable
Y$. Since we defined Y$ as "YESNO" the
leftmost three characters are "YES" and that's
what the computer displays. If we use the num-
ber 5 instead of the number 3 in parentheses, the
computer will print the entire variable
("YESNO"). Now try this one:
PRINT RIGHTS(Y$,2)

The computer displays the word NO. The
RIGHTS command causes the computer to
choose the two characters from the right side of
the variable, which forms the word "NO."

LEFTS and RIGHTS are used in various
types of word games as well as in practical
applications such as analysis of address infor-
mation. Here's a very short example to give you
an idea how this works:

10 PRINT "(CLRlENTER YOUR STATE AND ZIP C

ODE, THEN PRESS RETURN.": INPUT AS
20 Z$=RIGHT${AS,5)
30 PRINT "YOUR ZIP CODE IS " ; Z$

In line 10 we start with a PRINT statement
which clears the screen and asks the user to in-
put a state and zip code. The entire "string" of
information which is typed by the user is defined
as a string variable, AS.

Line 20 creates a new string variable (Z$) as
the five rightmost characters in the variable A$.
Unless the user put a space or extra information
at the end of the INPUT, Z$ should equal the
five-digit zip code.

Line 30 displays a message (in quotes) and
the zip code represented by the variable Z$. No-
tice that when we print string variables, the vari-
ables are outside quotation marks. Also, there is
no "leading space" in front of the zip code num-
ber stored in Z$, so you have to leave a space
after "IS" in line 30. Now, type NEW and press
RETURN to get ready for the next example.

102 COMPUTEfs Gazette May 1985

Using MID$ To Manipulate
Strings

The MIDS command works like LEFTS and
RIGHTS but is much more powerful because you
can use it to pick out specific bits of information
from any part of the string, not just the left or
right side. Here's an example to show how it
works:

10 P$="BESTEXAMPLE": PRINT MID$ ( P$ , 5 , 7 )

Type RUN and press RETURN. This ex-
ample looks more complicated than it really is.
But, like most BASIC magic, it's easy once you
know how it works. First, we create a string vari-
able called PS and define it as "BESTEXAMFLE".
Next, we print the word EXAMPLE from our P$
string.

Look at the MIDS command. First, inside the
parentheses is the name of the variable we're us-
ing — in this case, P$. Next comes the position
number — here, the 5 tells the computer to start
at the fifth position in the string, which is the let-
ter E. The last number (7) determines the length
of the information we're using from the string.
Remember, the MIDS command requires the
name of the variable, the position where we wish
to start, and (optionally) the length of the infor-
mation we wish to manipulate. Try this example:

10 A$="LEFTMIDDLERIGHT"
20 PRINT MID$(A$,1,4)
30 PRINT MIDS(AS,5,6)'
40 PRINT MID$(A$,11,5)
50 PRINT MID$(A$,1,15)
60 FOR X=7 TO 5 STEP-1
) ; s NEXT

PRINT MID$(A$,X,1

Line 10 defines the variable AS as the string
"LEFTMIDDLERIGHT".

Line 20 prints a substring four characters
long (length is 4) starting at the first character
(position 1). The result is the word "LEFT".

Line 30 prints a substring which starts at the
fifth position and displays six characters — the
word "MIDDLE".

Line 40 prints a substring which starts at the
eleventh position and displays five characters —
the word "RIGHT".

Line 50 prints the entire string, starting at
the first position and displaying all 15 characters.

Line 60 prints part of the string backwards.
We start with a FOR-NEXT loop which steps
backwards 1 position at a time, starting at po-
sition 7 and stepping down to positions 6 and 5
in order. The FOR-NEXT loop tells the computer
where to start in the string, so we use the X vari-
able from the FOR-NEXT loop in place of the po-
sition number in the MIDS command. The length
is 1 because although we're printing three
characters (positions 7 to 5, stepping backwards),

we're still printing one character each time. The
result is that the seventh character (D) is printed,
then the sixth character (I), then the fifth charac-
ter (M). The result is "DIM"

Using MID$ To Check For Right
Answers

One of the best and most powerful uses of MIDS
is to check to see if an answer is correct. You can
do this by scanning the input typed in by the
user, and searching to see if a key letter, word, or
phrase is included in the input. In the example
that follows, we'll ask who wrote the book, the
Home Computer Wars, and since the answer is
me, we'll scan the input for my last name
(Tomczyk) and then print a "right" or "wrong"
message. Type NEW and press RETURN, then
enter and run this program:

10 PRINT "[CLRlWHO WROTE 'THE HOME COMPUT

ER WARS' ": INPUT X$
20 FOR A=l TO LEN(XS)
30 IF MIDS(X$,A,7)="T0MCZYK" THEN GOTO 20

40 NEXT A
50 PRINT "WRONG... TRY AGAIN.": FOR T=l TO

500: NEXT: GOTO 10
200 PRINT "RIGHT!"

Line 10 clears the screen and displays the
opening message.

Line 20 is a FOR-NEXT loop which tells the
computer to step through the input string, one
character at a time— and uses the LEN command
to tell the computer how far to step through the
string. We'll get to the LEN command in a mo-
ment, but for now just remember that LEN
(LENgth) calculates how many symbols or digits
there are in a string of information, in this case,
X$.

Line 30 uses the MID$ command to search
for a group of seven characters (substring) which
matches "TOMCZYK" — the right answer.
Remember, the FOR-NEXT command tells the
computer to step through the string, one charac-
ter at a time. This MID$ command tells the com-
puter to keep checking the next group of seven
characters to see if they match our keyword. If
the computer finds the keyword "TOMCZYK,"
then it goes to line 200 to print the "RIGHT!"
message.

Line 40 completes the FOR-NEXT loop be-
gun in line 20.

Line 50 contains the "WRONG" message.
The program automatically drops down to this
line if it doesn't encounter "TOMCZYK" in the
user's answer.

Line 200 can be reached only if there is a
match in line 30.

Let's try something else with MID$, this
time using random numbers. Did you ever see a

program with multicolored stripes in the opening
title? The author probably used MID$- — a nice bit
of programming "magic" which you can use in
your programs, too.

You already know you can include graphics
and colors in a string — does that give you any
ideas? Type this program and run it (VIC owners
should substitute 22 in place of 40 in line 20). To
get the colors in line 10, hold down the CTRL
key and, at the same time, press each of the
eight color keys in order on your keyboard.
Reverse graphics symbols will appear where you
typed each color command:

10 gs = "{wht3{blkHredHcyn}{pur] (grn)

tBLUl (YEL) "
20 FOR X=l TO 40
30 R=INT(8*RND( 1 ))+l : PRINT MIDS (GS , R, 1 ) "

(RVS) ";: NEXT
40 GOTO 10

Type RUN and press RETURN. To stop the
program, hold down RUN /STOP and press RE-
STORE at the same time (RUN/STOP-RESET on
the Plus/4 and 16).

Line 10 creates a string variable (G$) which
contains eight keyboard color commands.
Remember, color commands can be stored in a
string variable just like letters and words.

Line 20 starts a FOR-NEXT loop which tells
us the program is going to repeat 40 times all the
actions between the FOR and NEXT commands.

Line 30 is the key line in this program.
Remember, because of the FOR-NEXT loop in
the previous line, all commands in line 30 will be
repeated 40 times. So, first, we choose a random
number from 1 to 8, using a random number for-
mula. Next, we use the random number as the
position number in the MID$ command. PRINT
MID${G$,R,1) means take the string of color
commands from G$ (which we defined in line
10), choose a random position in the string (the
same as choosing a random color), and then print
that color command once. Next, we print a
reverse space, which is the best way to display a
solid square on the screen. The semicolon makes
the colored squares appear horizontally, and the
NEXT command ties up the end of the FOR-
NEXT loop.

Line 40 is optional. Eliminating it prints only
one multicolored bar across the screen.

Using The LENgth Of Strings

The LEN command, which determines how
many characters there are in the string, is es-
pecially helpful in determining if someone has
typed an input which is too long or too short.
Try this:

10 AS= "NINETEEN CHARACTERS"
20 PRINT LEN{AS)

COMPUTE! 's Gazette May 19B5 103

Line 10 defines the string variable A$ as
"NINETEEN CHARACTERS." Line 20 displays
the length — how many characters or digits there
are in the string — which (coincidentally) is 19
including the space between the two words. How
can we use this information? For one thing, we
can use it to center a title horizontally on the
screen. Try this example (VIC owners should
substitute 22 for 40 in line 20):

10 TL?="HOME COMPUTER WARS"

20 PRINT "(CLR)";: FOR C=l TO (40-LEN(TE$
)}/2: PRINT SPC(l);: NEXT: PRINT TLS

Line 10 creates a variable called TL$ and de-
fines it as a title — in this case, another plug for
my book, The Home Computer Wars. This can be
any title within quotation marks. You can try
other strings in line 10; they'll be centered on the
screen.

Line 20 clears the screen. Since your com-
puter automatically moves down one line when-
ever a new PRINT command is encountered, we
use the semicolon to eliminate the linefeed. With
the semicolon, the printed title appears on the
first line. Without it, the title appears on the sec-
ond line.

The FOR-NEXT loop uses the LEN com-
mand in a centering formula. Here's the way it
works: First, it measures the length of the title
(TL$), then subtracts the length of the title from
the column width of the screen (40 foT most
Commodore computers or 22 for the VIC-20),
then it divides the remainder in half and prints
that many spaces at the beginning of the line.
After calculating and printing the spaces needed
to center the title, we print the title. Here's an-
other version of the same program:

10 TL$="HOME COMPUTER WARS "
20 L=(40-LEN{TL$))/2

30 PRINT "ECLR}";: FOR C=l TO L: PRINT SP
C(l); : NEXT: PRINT TL$

The difference here is that we broke apart
the program a bit and created a numeric variable
(L), which is the same as the centering calcula-
tion which gives the number of spaces needed at
the beginning of the title. Then, in line 30, we
use the value of L in a FOR-NEXT loop to print
the proper number of spaces in front of the cen-
tered title.

Error checkijig is also an excellent application
of the LEN command. One way to tell if the cor-
rect information has been typed in is to measure
the length of the input. Let's take a simple ex-
ample — the entry of a two-digit code for a state:

10 PRINT "tCLR) ENTER A 2-DIGIT CODE FOR Y
OUR STATE": INPUT W$

20 IF LEN(WS)>2 THEN PRINT "TOO LONG ... RE-
ENTER" : FOR T=l TO S00 : NEXT: GOTO 10

30 IF LEN(W$)<2 THEN PRINT "TOO SHORT.. .RE
-ENTER": FOR T=l TO 500: NEXT: GOTO 10

104 COMPUTE'S Gazette May 1985

Type RUN and press RETURN. Line 10
clears the screen and prints the opening prompt
message, then asks for an input. (To see how the
program works, try typing one letter, then try it
again with three or more letters.)

Line 20 tells the computer that if the length
of the state code typed in is larger than 2, then
print the message "TOO LONG...RE-ENTER",
pause for a "time delay count" to 500, then go
back to line 10 for a new input.

Line 30 is the same as line 20 except here
we measure whether the input is less than 2 dig-
its, and print the "TOO SHORT" message.

Notice we used the greater than (>) and less
than (<) symbols in lines 20 and 30.

You can use LEN to determine if a "string"
of information is the proper length, but what
about numbers? There's a way to check the
length of numbers, too, but first you have to use
another command — STR$.

The STR$ Command

The STR$ command performs real magic— it
turns a numeric variable into a string variable.
Try this:

10 A=10

20 A$=STRS(A)

30 PRINT AS

Line 10 creates a numeric variable (A) and
defines it as the number 10.

Line 20 creates a string variable (A$) which
contains the same characters as A. In other
words, A equals the number 10 and A$ equals
the string " 10". The difference between them is
that the computer recognizes A as a number ten,
which can be used in calculations. A$, on the
other hand, is a string. The computer can't use it
as a number — it's just a collection of characters.

To determine the length of a number for
error-checking, you need to convert the number
into a string variable using the STR$ command,
then use the LEN command to check the length
of the string and subtract 1. The reason we sub-
tract 1 is because BASIC automatically puts a
blank space in front of all positive numbers (to
leave room for a minus sign if the result of a
calculation is negative). The blank space gets car-
ried over when you convert a numeric variable to
a string variable, so, for example, converting
A = 10 to a string turns out like this: A$ = " 10"
with a space in front of the 10. Printing the
length of the new variable A$ yields a three be-
cause the blank space is counted. To get the real
digit length, you have to subtract one. Here's the
example (it works on numbers up to nine digits
long):

10 PRINT "ENTER A NUMBER'
20 A$=STR$(A)

INPUT A

30 PRINT "THERE ARE" LEN(AS)-1 "DIGITS IN
YOUR NUMBER."

What if you want to remove the blank space
from the front of a number? There are many
occasions when you don't want the blank space
there, for example, when you want to print a
dollar sign ($) right next to the number without a
space in between. To see what we're talking
about, here's what happens if you print a dollar
sign in front of a number without removing the
leading space:

10 PRINT
20 A=500:

'?"500
PRINT

'5 "A

Here's a handy technique for eliminating the
space between the dollar sign and number:

10 A=500

20 A$=MID$(STR$(A),2)

30 PRINT "S"A$

Until 1 learned this trick, this problem used
to drive me crazy with frustration. Finally, I
asked a programmer friend for some help and he
introduced me to the string functions discussed
in this column. Notice that the MID$ function
lacks the second number (the length of the
substring), which we said was optional up above.

If you omit the length, MID$ starts at the po-
sition specified and goes to the end of the string.
Jn line 20, M1D$ skips over the space to position
2 and reads all the rest of the string.

Here's another problem-solver. Did you ever
notice that BASIC drops zeros off the end of
numbers? For example, the number 5.00 is auto-
matically converted to 5. Try it:
PRINT 5.00

But what if you want to keep the zeros, to repre-
sent dollars and cents? Here's how to put the zeros

in:

10 PRINT "(CLR) ENTER A WHOLE NUMRER AND P

RESS RETURN": INPUT N
20 N$=MIDS(HTR$(N) ,2} +".00"
30 PRINT NS

There are many more uses for the five
BASIC commands we've covered in this column.
String functions can help overcome quite a few
programming obstacles and stumbling blocks, es-
pecially if you're a beginning programmer. Try
experimenting with these string functions by
combining them with other BASIC commands.
You'll be surprised how much "magic" is con-
tained in these few simple commands. m

MACHINE LANGUAGE FOR BEGINNERS

Getting And Sending

We recently received the following question in
the mail: Why do ML instructions have so many
forms? Why, for example, does the ADC instruction
have eight different modes, hence eight different
opcodes?

These different forms are called addressing
modes. There are several ways to address most
machine language (ML) instructions because that
gives the programmer greater flexibility.

ML programming, at its most primitive level,
amounts to supervising and designing pathways
for numbers to fly around inside the computer
during a program run. It's something like setting
up an elaborate pattern with dominoes. When
you tip over the first one, the rest of the action is
fast, predictable, sometimes quite beautiful.

But you have to arrange things so that they
go off at the right time and end up where they're
supposed to. That's where addressing comes in.
Instead of positioning each domino, however,
you attach a little note to most ML instructions.
This note, this address, will tell the instruction
where to go when the time comes for it to do its
little part in the overall plan.

Another Way To POKE

If we want to put the letter A on the 64's screen
in BASIC, we would POKE 1024,1. In ML, we do
something quite similar. We load the Accu-
mulator with the number that will become the
letter A when displayed on screen (LDA #1) and
then send it to the proper address, the first loca-
tion in screen RAM memory (STA 1024). ML
breaks everything down into single steps, so it

106 COMPUTErs Gazelle May 1985

uses two instructions which BASIC combines
into one:

POKE 1024,1 in BASIC becomes . , .

LDA#1

STA 1024 in machine language.

Let's look more closely at that second step.
STA is the ML instruction, 1024 is the address.
This 1024 is an unadorned number (without any
commas, parentheses, or # signs which would
change the meaning of that number in ML). The
unadorned 1024 means that we have chosen to
use an ML addressing mode called Absolute
Addressing. It means that the number 1 will be
sent directly to address 1024. If you address it
differently, STA 1034, you will place the letter A
ten spaces to the right on the screen. And, as
we'll see shortly, you can choose some quite exotic
ways to address your little packages. For ex-
ample, 1024,Y is a special addressing mode
called Indirect,Y, and it has its own special way
of sending the letter A. More about Absolute and
Indirect,Y Addressing in a minute.

If all this sounds alarming, recall that there
are various modes in BASIC, too. It's just that
you're probably already used to them and don't
give them a second thought. For example, there
are several modes for the PRINT command:

PRINT X
PRINT "X"
PRINT TAB (X)

In ML, there are a total of 13 possible
addressing modes, but some of them are virtual
duplications, some are intuitively obvious, and
some are nearly useless. So, when faced with the

task of understanding ML programming, it's
good to separate the modes into these categories
and learn to use the three important ones.

The Big Three

To learn the modes, let's explore some ways that
we could choose to handle simple addition, ADC
(ADd with Carry) is an important instruction in
ML. Let's take a quick look at the eight address-
ing modes that are available when you want to
add bytes together with the ADC instruction. As
you'll see, these eight modes actually boil down
to only three: Immediate, Absolute, and
Indirect,Y. Remember: Some addressing modes
are functionally identical and others are func-
tionally useless.

1. Immediate Mode — written in ML
programming as ADC #10. This is one of the
most useful of all since you don't need to look
anywhere else in RAM for the number that's go-
ing to be added to the number already in the
Accumulator. Here's how you would add 5 + 10
using Immediate Mode addressing:

CLC; (always clear the carry before starting any

addition)
LDA #5; (put 5 into the Accumulator)
ADC #10; (add 10)

That's it. If you execute this little ML pro-
gram, you'll find that the accumulator now holds
15. (By the way, the semicolon tells the assem-
bler to ignore what follows, it's just a comment.
It works like REM in BASIC.)

As you see, Immediate Mode addressing is
accomplished by simply putting the # symbol in
front of a number. It means, "use this number
right here" (as opposed to looking in RAM mem-
ory for the number). If you leave off the # (as in
LDA 5) you would put whatever number was cur-
rently in RAM memory location five into the
accumulator.

2. Zero Page — ADC 10 — not too often used.
It means add the number in the Accumulator to
whatever number is currently in RAM memory
address 10. This addressing mode can only deal
with the first 256 bytes in the computer (a page
is a 256-byte long chunk of memory; this is the
lowest page in memory so it's called zero page).

This first page is very heavily used by the
computer's operating system and by BASIC. It's
the fastest memory addressing method, so the
computer uses it for time-critical operations like
the internal clock, fetching information from a
BASIC program during a RUN, etc. You can't
store your own ML programs in zero page with-
out causing havoc. The only zero page addresses
which you can use safely are 2, 251-254, and, if
you're not using the Datassette during the ML
program's execution, 163-177, That's not much

space. You'll want to store address pointers in
these locations, however, because they assist
with a very useful addressing mode called In-
direct Y, which we'll get to in a minute.

3. Zero Page,X— ADC 10,X— practically use-
less. Here you add the number in the accu-
mulator to whatever number is in address 10 + X.
In other words, if the X Register holds a 6, you
would add the number in the Accumulator to
whatever number is in address 16. Since this
addressing mode has little known value (and
none for beginning ML programmers), we'll
bring any further discussion of it to a sudden
halt.

4. Absolute— ADC 1000— you'll use this
mode all the time. It addresses any memory loca-
tion in the computer. It's straightforward, you
just put the address after the instruction; no com-
mas, no # symbols, no parentheses, just a simple
number.

This example would add the number in the
Accumulator to whatever number was currently
in address 1000. Notice that it's difficult to tell
the difference between this mode and zero page
addressing. ADC 10 could be thought of as Ab-
solute instead of zero page. However, your
assembler will automatically detect if an address
is lower than 256 and create the correct zero
page mode opcode.

Especially For Loops

5. Absolute ; Y— ADC 1000,Y. This is an "in-
dexed" addressing mode and is very similar to
Zero Page,X discussed above, Absolute,Y is,
however, useful when you have a table of infor-
mation in memory and want to access it quickly.
For example, if you've previously stored the ages
of all your friends in a table starting at address

1001, you could find the age of the fifth friend in
the list by LDY #5: LDA 1000,Y since that would
retrieve the number in address 1005. (The Y Reg-
ister is added to the 1000 to produce the actual
address used.)

This addressing mode is also useful if you
want to move an entire block of memory to some
other place. You could move a 256-byte-large
block by setting up a simple loop and using the
Y as an index:

Here, the labels SOURCEBYTE and
TARGETADDRESS can be replaced by the actual
addresses of your blocks. The point to notice is
that you'll keep looping back to LOOP until Y
counts up to 255, and then one additional trip
through the loop will reset Y to and you'll fall
through the BNE (Branch if Not Equal to zero)
instruction.

Want to move larger blocks? The whole
screen, maybe? It's not hard:

LDY#0
LOOP LDA SOURCEBYTE, Y

STA TARGETADDRESS,Y

LDA SOURCEBYTE + 256, Y

STA TARGETADDRESS+256,Y

INY

BNE LOOP

This will move 512 bytes. For larger block
moves, just stick in more LDA/STA pairs.

6. Absolute,X— ADC 1000,X. Exactly the
same as Absolute,Y except you use the X Register
as your index. Used the same way and for the
same purposes.

7. Indirect,X— ADC (10,X)— fundamentally
useless. Forget about this mode.

The Puzzler

8. Indirect, Y— ADC (10),Y. A very useful
mode, but takes a bit of head scratching at first
to see just what it does. In effect, you prearrange
a little two-byte address in zero page (called a
pointer) and then you bounce off that pointer
(plus the Y Register) to the real target. Here's
how we could move 256 blank characters to the
screen on the 64 using Indirect,Y:

TARGET = 1024; (address of the screen RAM)
LDA #<TARGET; (load the low byte of the

target address)
STA 251; (a safe place in zero page to hold our

pointer)
LDA #>TARGET; (fetch the high byte of the

target address)
STA 252; (store high byte into pointer)
LDA #32; (the blank character)
LDY #0; (set our index to zero)
LOOP STA (251), Y; (bounce off the target + Y)

INY
BNE LOOP

Why, you might well ask, go to all the trou-
ble of setting up this pointer when you can use

the ordinary Absolute,Y to achieve the same re-
sult? Besides, Absolute is much easier to
understand.

You have a point. But this Indirect,Y mode is
faster and more flexible. For example, to move
the whole show up 256 bytes, all you need to do
is INC 252, which raises your pointer by 256. So,
if you were sending a copy, an image, of a truly
huge amount of memory to a disk, it might be
easier to manipulate things with Indirect, Y. You
can go ahead and program without this address-
ing mode, but it is a valuable tool and you'll
likely end up learning to use it frequently. It
solves some problems for the programmer in a
most efficient way.

Its basic advantage is that Indirect,Y pointers
are variable. They're not carved into your ML
program like an Absolute address. Rather, they
exist in ordinary RAM, outside your program,
and you can fiddle with the pointer easily by
storing new numbers into it, INC or DECing it,
etc. Indirect,Y is a particularly flexible addressing
mode once you get the hang of it. It's nice for
keeping track of the position of players and ene-
mies in games, and so forth.

Creatures From The Eleventh
Dimension

As for the other advantage of Indirect, Y — that it's
a faster addressing mode — don't bother worrying
about speed. There are usually several ways to
accomplish the same thing when programming.
Some are more compact, some easier to under-
stand, some faster. But, at the lightning speeds of
ML, you need never worry about maximizing
speed. Only Creatures from the Eleventh Dimen-
sion would ever be able to tell that your program
was running five milliseconds slower than it
might.

Most of the important ML instructions (STA,
LDA, SBC, CMP, for example) can use all eight
of these addressing modes we've discussed.
There are other ML instructions which can use
some, but not all of these modes. A few remain-
ing instructions have weird modes of their own.
Most of the time you can let your assembler help
you. If you accidentally try to use a mode that's
not available to a particular instruction, your
assembler will alert you,

However, this covers most of what you'll
need to know about addressing to get started
programming effectively in ML. There are 13
modes altogether, but the five we've not dis-
cussed are either obvious and require no special
attention from the programmer (INY uses a mode
called implied addressing because you give no
address, you're just raising the Y Register by 1)
or are virtually never used (Zero Page,Y). «j}

Understanding Sorts

Arieh Shamash

With a short sort routine, your Com-
modore computer can easily alphabetize
and organize a list of words or numbers.
This tutorial explains three different types
of BASIC sorts, and offers program exam-
ples. A hi-res screen display graphically
illustrates the results. For the VIC, 64,
Plus/4, and 16.

If the second value is less than the first, then you
put the first in a temporary variable, put the sec-
ond in the first, and the temporary first value
into the second. But if the first is less, don't
switch them. Either way, increase the counter
and the sort continues.

Confused? Don't be. The following programs
can help you understand three different al-
gorithms: the bubble sort, the shell sort, and the
quicksort. (An algorithm is a set of procedures
for solving a problem.)

Before getting started, VIC and 64 owners
should read the special instructions for entering
the programs. Owners of the Plus/4 and 16 can
just type the programs and save to tape or disk.

Special VIC Instructions

The three VIC programs are written for an un-
expanded VIC. To protect BASIC from the hi-res
graphics, you must enter this line before loading
and running each program:

POKE6144,0:POKE44,24:NEW

Type in the programs, save them to tape or
disk, and (before loading the programs) enter the
POKEs above.

Special 64 Instructions

Before typing the three sort programs, enter "Hi-
Res Routine" (Program 4), and save it. This rou-
tine is necessary; the other three 64 programs
won't work without it. While the Hi-Res Routine
is still in memory, enter and save "Bubble Sort"

110 COMPUTE'S Gazette Way 1985

(Program 5). Next type NEW, load the previously
saved copy of Hi-Res Routine, and enter and save
the next program "Shell Sort." Repeat this proce-
dure for the final program, loading Hi-Res Rou-
tine before entering and saving "64 Quicksort."

A Visible Sort

Go ahead and run each of the programs; we'll
learn how they work a little later. The bubble
sort should be run first because it's the slowest.
The shell sort works about four times faster. And
the quicksort is faster yet, taking about half as
much time as the shell sort.

The computer needs a few seconds to set up
and clear the high-resolution screen. It also
makes up an array containing 99 random num-
bers ranging from 1 to 99. Due to memory and
screen limitations, the VIC sorting programs use
75-element arrays.

The first thing you see is a galaxy of dots
scattered across the screen. Each line going
across the screen corresponds to one of the vari-
ables in the array. So if variable L%(1) holds the
value 1, there's a dot in the upper-left corner. If
L%(2) holds a 50, its corresponding dot is in the
middle of the second line from the top.

A properly sorted and organized array
would appear as a roughly diagonal line running
from the top left to the bottom right. Each of the
sorting routines transforms the chaotic mess of
random dots into a diagonal line.

When the sort is finished, press any key to
continue. The screen will display the number of
items sorted and the time used. Running a sort
program more than once may result in different
times, depending on the initial distribution of the
random numbers.

Comparing And Trading

The way most sorts work is by comparing two
items in an array and trading them if they're out
of order. In each of the three programs is a line
that looks something like this:

IF L%{T) > L%(T + 1) THEN TE - L%(T): L%(T) -
L%(T+1): L%(T + 1) = TE

The variable T points to an element in the
array. If it happens to hold the value 4, then
L%(4) is compared to L%{4 + 1), The fourth
number in the array is compared to the fifth. If
item four is greater than number five, they're out
of order and need to be switched. The value in
L%(4) is put into the variable TE (an abbrevi-
ation for temporary), the value from L%(4 + 1)
slides over into L%(4), and the value from TE
goes into L%{4 + 1).

So, if necessary, the program trades the val-
ues in the two variables, putting them into order.
By comparing and trading over and over, the list
is eventually put into order.

If the first number is less than the second,
no trading is necessary, of course, and the sort
continues with the next item on the list.

The Slow, Reliable Bubble

The slowest of the three sorts is the bubble sort.
It's usually the first sorting algorithm taught to
beginning programmers, because it's fairly easy
to understand. This is how it works:

10 FORI=S-lT01STEP-l ;F0RT=1T0I

20 IFL%(T)>L%(T+l)THENTE=Lft{T) :L% (T)=L% (T

+1) :L%(T+1)=TE
30 NEXT: NEXT

This is sorting at its simplest— a compare/
trade line inside two loops. The variable S is the
size of the array. The outer I-loop counts back-
wards (STEP -1) from one less than the size (S
— 1) down to one. The inner T-loop counts for-
ward from one to the value of I.

Let's trace a bubble sort through a few
comparisons. We'll start with an array of nine
unsorted numbers. Since the size (S) of the list is
nine, the outer I-loop begins at S — 1, which is
8. The inner loop counts from one up to I (8),
comparing and trading.

First pass (I = 8)

The bold numbers are the ones being com-
pared. A bubble sort is methodical: Is item 1 (58)
greater than item 2 (69)? No, don't trade them.
Next, compare items 2 and 3. They're OK, don't
trade. Now compare item 3 (91) against item 4
(7) — 91 is greater, so they get traded.

After eight comparisons, the largest number

(97) has fallen to its proper position (item 9). As
the second pass begins, the I-loop changes the
value of I from 8 to 7. The inner T-loop will now
count 1 to 7. On the third pass, T counts 1 to 6,
then 1 to 5, and so on.

Notice how the small numbers move toward
the top of the list one spot at a time. This
contributes to the relatively slow speed of the
bubble sort. But the real inefficiency appears in
longer lists. Bubble sorting nine items takes 36
comparisons (8 + 7+6 + 5+4 + 3 + 2 + 1).
If you double the size of the list to 18, the number
of comparisons more than quadruples, to 153.

Multiplying the size of the list by two means
multiplying the time used by four. Bubble sorting
a long list can take hours.

The More Efficient Shell

If you've already tried the hi-res shell sort pro-
gram, you've probably noted that the dots move
in a different pattern (compared to the bubble
sort). And it finishes the sort in one-fourth the
time. (This procedure is named after its inventor,
Donald Shell.) When you strip away the random
numbers and hi-res routines, it looks like this:

10 g=int(s/2)

20 n=0:fori=1tos-g

It works like a bubble sort, but with a twist.
Line 30 compares and trades, but instead of
comparing neighbors, it looks further down the
list. The variable L%(I) is checked against
L%(I + G). G starts as half the length (S) of the
list and is reduced by half in later loops. The
variable N flags a trade. If a comparison causes a
trade, N = 1 and the loop is repeated. If no
trades have happened, N = and G is cut in
half.

starts at four (half of nine, rounded down). Item
1 (58) is compared to item 5(12) and traded.
Item 2 (69) is traded with item 6 (37), and so on
down the list. Since there was at least one trade
on the first pass, the flag N equals one and the
gap G stays at four. On the second pass, nothing
is traded, so N = and G is reduced by half, to
two.

On the third pass, we compare items 1
against 3, 2 against 4, 3 against 5, and so on. As
soon as there are no more trades, G is reduced
by half again. The process continues until G is
less than 1.

A bubble sort moves things one spot at a
time. The shell sort is faster because the elements
of the array are transferred longer distances.

But long lists are still a problem. If the size
of the list doubles, the sorting time approxi-
mately triples. It's not as long as the bubble sort,
but the extra time adds up. What we need is a
method where doubling the list only doubles the
time.

Quicksort: Divide And Conquer

The quicksort algorithm looks quite complicated:

10 DIML%(S) ,S%{20)

20 S%{1)=1 :S%(2)=SsP=2

30 L=S%(P) :P=P-1:F=S%(P) :P=P-1 tI=F

40 J=L;D=L%((F+L)/2)

50 IFL%(I)<DTHENI=I+1:GOTO50

60 IFL%(J)>DTHENJ=J-1:GOTO60

70 IFI<=JTHENT=L%(I) sL% ( 1 )=L% ( J) :L%(J)=T:

1=1+1 ;J=J-1
80 IFK-JTHEH50

90 IFF<JTHENP=P+1 :S% ( P )=F: P=P+1 :S% ( P )=J
100 F=IiIFF<LTHEN40
110 IFPO0THEN30

The list is still in L%, but there's a new ar-
ray (S%) which acts like a stack, keeping track of
which sections are being sorted. The variable P is
a pointer, used by the array S%(P). You'll also
notice F and L (first and last), I and J (indexes to
the list L%), and D (dividing line).

The comparisons happen in lines 50 and 60;
values are traded in 70.

To understand the quicksort, imagine a well-
shuffled deck of cards you want to put in order.
Pick a dividing line. It could be anything, but
let's use nine. Any card less than nine goes in
one pile, cards greater than (or equal to) nine are
put in a second pile. Now forget about the first
bunch of cards (you'll look at them later). The
second group is divided again, this time using
queens. You put nines through jacks in one pile,
queens and kings in another. Now sort the
queens and kings. When they're done, go back to
the other cards.

The list is broken down into smaller and
smaller categories, until you reach a point where
only one or two items remain:

123456789
(midpoint D is #5: 12)

58 69 91 7 12 37 97 65 89 1
12 69 91 7 58 37 97 65 89 2

12 7/37/58/69 89 65 / 91 97 8
12 7/37/58/69 65 / 89 91 97

The list has nine numbers, so the middle is
item 5 (containing a 1 2). This is the first mid-
point. Starting at the left, look for a number
greater than (or equal to) 12. The first number
(58) works, so now we go to the end of the list.
We need a number less than (or equal to) 12. It
turns out to be 12. Now switch the two.

The index, I, moves forward, J moves back-
ward. The next number (69) is more than 12, so J

112 COMPUTE!* Gazette May 1985

moves backward to find a number less than 12
(7). The two are traded. As soon as the indexes
cross, we pick a new midpoint.

The numbers 12 and 7 are at the beginning
of the list, in a separate "pile" to be sorted later.

The next dividing line is the number half-
way between item 3 and item 9 (3 + 9 is 12,
and 12/2 is 6, so the halfway point is item 6,
containing a 37). Only one exchange takes place,
and 37 is put into a pile all by itself. Forget about
37 for now, we have to sort elements 4-9. Now
the midpoint is item 6 (91). Two numbers are
traded.

The numbers 69, 58, 89, and 65 are put
aside for later. Now, 91 and 97 are put in order.
Since we're at the end of the list, we have to go
back to the previous piles.

After just eight trades, the last three num-
bers are in the correct place, and the beginning
of the list has been subdivided into manageable
piles containing just one or two numbers.

Quicksort lives up to its name — it is quick.
And if the size of the list is doubled, the sorting
time increases by slightly more than double,
making it the best choice for long lists.

Alphabetizes And Pointers

The three different ways of sorting can be used
to alphabetize string arrays as well. Less-than,
greater-than, and equals can be used to compare
words. The letter A is less than B, for example,
because its ASCII value is smaller. (For a com-
plete list of ASCII values, see the appendix in the
User's Guide).

The compare/trade method used in these
programs is called "replacement sorting," be-
cause when two items are out of order, they
trade places on the list. When the program is
done, the list is in order.

In some lists (an address file, for example)
you may want to sort by different fields. One
sort would be alphabetical by last name, another
would be in zip code order. The algorithm you
would use— bubble, shell, or quick — would be
similar, but you would leave the list intact and
sort pointers:

A$(1)="D" B(l) = 2

A$(2)="A" B(2)=4

A$(3)="C" B(3)=3

A$<4)="B" B(4)=l

A${5) = "E" B(5)=5

The list on the left is scrambled, but the
pointers are in order. A$(2) ("A") should be first
at the top of the list, so the pointer B(l) holds a
2. To print them in order, FORT=IT05:
PRINTAS(B(T)):NEXTT. The compare/trade routine
would have to change to something like this;

IF L%(B(T» > L%(B(T+1» THEN TE = B(T): B(T) =
B(T+1):B(T + I) = TE

The hi-res screen illustrates the process of sorting. Here,
"Quicksort" has finished organizing the last third of the
list (lower right-hand corner),

You still compare two numbers in the first
array (L%, in this case), but if they're out of or-
der, you trade values in the second array (B(T)).
Before the sort starts, you have to initialize the
pointers: FORT=lTOS: B<T)=T: NEXT.

Using a pointer sort and relative disk files,
an unexpanded VIC-20 could alphabetize a list of
1000 strings, far more than would ordinarily fit
into memory.

COMPUTE! s Gazette May 1986 113

POWER BASK

Searchlight

Katherine Myers

You can save time with this short machine
language routine that spotlights errors in
BASIC programs. A good tool for debug-
ging programs you've written or those
you ve typed in. For the VIC and 64.

Your program comes to an abrupt halt and the
words SYNTAX ERROR IN 50 are on the screen.
You list line 50 and study it time and again
wondering where the problem lies. Why, with all
the amazing speed and power of your computer,
won't it show you where your error is?

I know I've spent many hours, especially
when I first got my computer, staring at lines I
thought were written correctly and wondering
where that error was. If you've spent too much
time searching for errors, this program is for you.

"Searchlight" is written in machine language
(in the form of a BASIC loader) and is easy to
use. Type in the program, save a copy, and run it
before you load or start typing the program
you'll be working on.

A Safe Section Of Memory

It first asks you for the starting address so you
can locate it where it won't interfere with your
program or any other machine language utilities
in memory. It's only 121 bytes long, so it will fit
in the cassette buffer. Of course, if you're using
tape, this would he inappropriate.

It's important to put the program somewhere
safe in memory where BASIC cannot interfere
with it. Here are some suggestions for a starting
address: Disk users can use 828 (the beginning of
the cassette buffer on both the VIC and 64). On
the 64, you can use the 4K section at 49152-53247
(remember to allow for 121 bytes); 50000 would
work, and it's easy to remember. If you have a
VIC and tape drive, you'll have to put it in a pro-
tected area of BASIC memory. Before running
Searchlight, follow these instructions:

114 COMPUTEIs Gazatta May 19BS

1. Enter TM = PEEK(55) + 256*PEEK(56):
SA = TM-121:PRINTSA and write down the
number which will be the starting address.

2. Next, move the top of memory down with
HB = INT(SA/256):LB = SA - 256*HB:
POKE55,LB:POKE56,HB:CLR

These two lines will work on a VIC (un-
expanded or expanded) or a 64.

Line 20 of the 64 version is written for the
user's protection — it prevents the program from
being inappropriately located — to screen RAM,
for example. It also won't let you locate it in an
address below 820 or in ROM. Since the VIC's
screen memory and BASIC move around,
depending on the amount of expansion, the VIC
version does not check for inappropriate starting
addresses.

After choosing a location, the loader POKEs
in the data for the machine language routine and
erases itself with the NEW command if all the
data entered is correct. Be sure to note the loca-
tion you first selected as you'll have to SYS to it.

Putting It Into Action

When you wish to use Searchlight, SYS to the
address you've chosen before you run your pro-
gram. I usually put the SYS command in the first
line of the program I'm testing so I don't have to
type it in each time. When you run a program
and an error is encountered, type LIST. The line
which contains the error will be listed with an
arrow pointing to the appropriate place in the
code. For example, it may be in a spot where
some code is missing, to a place where you're
trying to go to a nonexistent line number, and so
on. If the arrow is placed in a statement that con-
tains parentheses, check to see if there is an
equal number of open and closed parentheses. If
there isn't an arrow in the statement listed, the
error is at the end of the line. After Searchlight
lists an erroneous statement and it is corrected,
run the program again. If another error exists,
this, too, will be listed. Keep running it until the
program is free of errors.

Any time RUN/STOP-RESTORE is used,
Searchlight is deactivated. This is programmed
for user convenience — you don't have to turn off
the machine or remember any POKEs. Also,
RUN-STOP acts like a TRACE function. Press
RUN-STOP when a program is running, and an
"error" appears on the line that is executing. This
can be useful in testing and debugging.

When you make a correction, be sure to de-
lete the arrow before pressing RETURN. If you
don't, the arrow will become part of the BASIC
line in which it appears.

Certain errors, like those encountered during
an INPUT statement (EXTRA IGNORED and
REDO FROM START, for example) will not ac-
tivate Searchlight since these are user errors and
not problems related to a program line, Also, the
program will not indicate errors encountered dur-
ing statements entered in direct mode.

This program can save many hours of
searching for errors — especially when you're
dealing with long lines. You can use it for your
own programs or those you type in from a maga-
zine. It's especially helpful when typing in a pro-
gram since it points to the place in the line
where you need to look. You won't have to start
from the beginning of that line when comparing
your version with the printed copy.

How To Type In
COMPUTERS GAZETTE Programs

Each month, COMPUTEl's GAZETTE publishes programs
for the VIC-20, Commodore 64, Plus 4, and 16, Each
program is clearly marked by title and version. Be sure
to type in the correct version for your machine. Also,
carefully read the instructions in the corresponding
article. This can save time and eliminate any questions
which might arise after you begin typing.

We publish two programs, which appear periodi-
cally, designed to make your typing effort easier: The
Automatic Proofreader, and MLX, designed for enter-
ing machine language programs.

When entering a BASIC program, be especially
careful with DATA statements as they are extremely
sensirive to errors. A mistyped number in a DATA
statement can cause your machine to "lock up" (you'H
have no control over the computer). If this happens,
the only recourse is to turn your computer off then
back on, erasing whatever was in memory. So be sure
to save a copy of your program before you run it. If your
computer crashes, you can always reload the program
and look for the error.

Special Characters

Most of the programs listed in each issue contain spe-
cial control characters. To facilitate typing in any pro-
grams from the GAZETTE, use the following listing
conventions.

The most common type of control characters in
our listings appear as words within braces: {DOWN}
means to press the cursor down key; {5 spaces}
means to press the space bar five times.

To indicate that a key should be shifted (hold
down the SHIFT key while pressing another key), the
character is underlined. For example, A means hold

down the the SHIFT key and press A. You may see
strange characters on your screen, but that's to be ex-
pected, If you find a number followed by an under-
lined key enclosed in braces (for example, {8 A}),
type the key as many times as indicated (in our ex-
ample; enter eight SHIFTed A's). To type {SHIFT-
SPACE}, hold down the SHIFT key and press the
space bar.

If a key is enclosed in special brackets, i 3 , hold
down the Commodore key (at the lower left corner of
the keyboard) and press the indicated character.

Rarely, you'll see a single letter of the alphabet
enclosed in braces. This can be entered on the Com-
modore 64 by pressing the CTRL key while typing the
letter in braces. For example, {A} means to press
CTRL-A.

The Quote Mode

Although you can move the cursor around the screen
with the CRSR keys, often a programmer will want to
move the cursor under program control. This is seen
in examples such as {LEFT}, and {HOME} in the pro-
gram listings. The only way the computer can tell the
difference between direct and programmed cursor
control is the quote mode.

Once you press the quote key, you're in quote
mode. This mode can be confusing if you mistype a
character and cursor left to change it. You'll see a
reverse video character (a graphics symbol for cursor
left). In this case, you can use the DELete key to back
up and edit the line. Type another quote and you're
out of quote mode. If things really get confusing, you
can exit quote mode simply by pressing RETURN.
Then just cursor up to the mistyped line and fix it.

MLX

Machine Language
Entry Program

For Commodore 64 And VIC-20

Charles Brannon, Program Editon

MLX is a labor-saving utility that allows almost
fail-safe entry of machine language programs pub-
lished in gazette. You need to know nothing
about machine language to use MLX — it was de-
signed for everyone. There are separate versions for
the Commodore 64 and expanded VTC-20 (at least
8K).

MLX is a new way to enter long machine language
(ML) programs with a minimum of fuss. MLX lets you
enter the numbers from a special list that looks similar
to BASIC DATA statements. It checks your typing on
a line-by-line basis. It won't let you enter illegal
characters when you should be typing numbers. It
won't let you enter numbers greater than 255 (forbid-
den in ML). It won't let you enter the wrong numbers
on the wrong line. In addition, MLX creates a ready-
to-use tape or disk file. You can then use the LOAD
command to read the program into the computer, as
with any program:

LOAD "filename",l,l (for tape)
LOAD "filename",8,l (for disk)

To start the program, you enter a SYS command
that transfers control from BASIC to machine language.
The starting SYS number always appears in the
appropriate article.

Using MLX

Type in and save MLX (you'll want to use it in the
future). When you're ready to type in an ML program,
run MLX. MLX asks you for two numbers: the starting
address and the ending address. These numbers are
given in the article accompanying the ML program.

You'll see a prompt corresponding to the starting
address. The prompt is the current line you are enter-
ing from the listing. It increases by six each time you
pnter a line. That's because each line has seven
numbers— six actual data numbers plus a checksum
number. The checksum verifies that you typed the
previous six numbers correctly. If you enter any of the
six numbers wrong, or enter the checksum wrong, the
computer rings a buzzer and prompts you to reenter
the line. If you enter it correctly, a bell tone sounds
and you continue to the next line.

MLX accepts only numbers as input. If you make
a typing error, press the INST/DEL key; the entire
number is deleted. You can press it as many times as
necessary back to the start of the line. If you enter
three-digit numbers as listed, the computer automati-
cally prints the comma and goes on to accept the next
number. If you enter less than three digits, you can
press either the SPACE bar or RETURN key to ad-

1 18 COMPUTE!'* Gazette May 1985

vance to the next number. The checksum automati-
cally appears in inverse video for emphasis.

To simplify your typing, MLX redefines part of
the keyboard as a numeric keypad:

U I O 7 8 9

H I K L become 4 5 6

M , . 12 3

MLX Commands

When you finish typing an ML listing (assuming you
type it all in one session) you can then save the com-
pleted program on tape or disk. Follow the screen
instructions. If you get any errors while saving, you
probably have a bad disk, or the disk is full, or you've
made a typo when entering the MLX program itself.

You don't have to enter the whole ML program
in one sitting. MLX lets you enter as much as you
want, save it, and then reload the file from tape or
disk later,

MLX recognizes these commands:

SHIFT-S: Save SHIFT-N: New Address

SHIFTrL: Load SHIFT-D: Display

When you enter a command, MLX jumps out of
the line you've been typing, so we recommend you do
it at a new prompt. Use the Save command to save
what you've been working on. It will save on tape or
disk, as if you've finished, but the tape or disk won't
work, of course, until you finish the typing. Remem-
ber what address you stop at. The next time you run
MLX, answer all the prompts as you did before, then
insert the disk or tape. When you get to the entry
prompt, press SHIFT-L to reload the partly completed
file into memory. Then use the New Address com-
mand to resume typing.

To use the New Address command, press SHIFT-N
and enter the address where you previously stopped.
The prompt will change, and you can then continue
typing. Always enter a New Address that matches up
with one of the line numbers in the special listing, or
else the checksum won't work. The Display command
lets you display a section of your typing. After you
press SHIFT-D, enter two addresses within the line
number range of the listing. You can abort the listing
by pressing any key.

What if you forgot where you stopped typing?
Use the Display command to scan memory from the
beginning to the end of the program. When you reach
the end of your typing, the lines will contain a ran-
dom pattern of numbers. When you see the end of
your typing, press any key to stop the listing. Use the
New Address command to continue typing from the
proper location.

See program listings on page 127.

HINTS&TIPS

Password Protection
For BASIC Programs

Shawn K. Smith

If you've discovered a clever timesaving
technique or a brief but effective program-
ming shortcut, send it to "Hints & Tips/'
c/o COMPUTED GAZETTE. If we use it, we'll
pay you $35. Due to the volume of items
submitted, we regret that we cannot al-
ways reply individually to submissions.

Bulletin boards, telecommunication services, and
business computers often require users to enter a
password before they're allowed access to the
system. Password protection prevents un-
authorized persons from getting into the
computer.

Have you ever wanted to add a password to
a BASIC program? It's not very hard. You may
have programs you don't want a younger brother
or sister to use. Or, in a business situation, you
may want to keep certain employees from play-
ing around with important programs.

Password protection is not the same as copy
protection. Copy protection prevents people from
making backups, sometimes called "pirated" or
"bootleg" copies, of commercial programs. Add-
ing a password routine doesn't affect loads or
saves. Users can still copy a program that re-
quires a password, but the copy won't do them
much good unless they know the secret code.

A Simple Password

The first scheme is so simple, it will work only
with small children and users who know nothing
about BASIC. Let's say you've chosen the pass-
word "UNIQUE'.' Add these lines to your program:
10 PRINT "ENTER PASSWORD": INPUT A$
20 IF A$ <> "UNIQUE" THEN PRINT "SORRY":

GOTO10
30 (program continues)

Let's call this a "level 1" password routine.
The user inputs a string variable (A$) and the
program checks it against the word UNIQUE. If
A$ doesn't match, the program loops back to line
10. You could replace GOTO 10 with NEW to
erase the program when the password is wrong.

The obvious problem is that if someone
loads the program and types LIST, he'll see the
password. Then, he types RUN and enters
UNIQUE.

We need a LIST preventer, to keep the pass-
word secret.

Stopping LIST

Entering shifted characters in a REM statement
can give strange results. For example, REM
(SHIFT-F) will LIST as REM ASC. Most are
translated into BASIC keywords. But one of the
shifted letters has a curious effect: SHIFT-L
makes a program listing stop and print 7SYNTAX
ERROR. Add this line to the above program:
15 REM (SHTFT-L)

If your computer is in upper/lowercase
mode, you'll see a capital L after the REM. In
uppercase/graphics mode, the SHIFT-L character
looks like an expanded capital L character.

Type LIST and lines 10 and 15 print, but
not 20. The listing stops with a SYNTAX ER-
ROR. (By the way, if you use SHIFT-L in your
disk ID, it makes the directory unlistable to you
or anyone else). The SHIFT-L trick can also be
used when you're programming and want list-
ings to stop at a certain line.

A smart user could do one of two things.
Since line 15 has some sort of problem, he or she
could enter LIST16- (try it). There's the pass-
word, for all the world to see. Or, just delete 15

COMPUTED Gazette May 1985 119

by entering 15 and pressing RETURN. LIST will
now reveal the secret word.

Can we change the line number so the com-
puter thinks it is line 15, but the user thinks it is
something else?

A False Line Number

Move the cursor to a blank line, hold down the
SHIFT key, and press the INST/DEL key. Now
type an unshifted INST/DEL. The INSerT key
puts you into insert mode, which is almost
identical to quote mode. But you can delete in
quote mode, while insert mode displays a delete
as a reversed letter T. Here's how to put deletes
into a REM statement:

1. Enter 15 REM"" (note there are two pairs
of quotation marks).

2. Use the DELete key to erase the second
quotation mark.

3. Type CTRL-9 (RVS ON) followed by
seven unshifted T's.

4. Now enter 30 REM, a quotation mark,
and a SHIFT-L.

The reverse T's act like delete keys and erase
the previous seven characters when listed. The
30 REM is then printed. LISTing the program
makes it look like line 30 follows line 10, when it
is really line 15. An unauthorized user who tries
to list past 30 or delete line 30 won't see the
password at line 20.

A REM followed by a quotation mark and
the right number of reverse T's can also be
added to the end of a regular BASIC line to
cover up variables (the password, for example) or
to mislead users who list the program. This is
about as far as we can go with password routine
number one, though. Now let's look at a dif-
ferent type of password program.

Twisting The line Links

BASIC lines are stored in memory according to
definite rules. A few PEEKs will illustrate how
the rules work.

First, type NEW and enter this line: 10
REMAB. Then type the following line without a
line number:

B =PEEK<43)+ 256*PEEK(44>.PRINTB:FORI= BTOB + 9:
PRINTI,PEEK(I):NEXT

Locations 43 and 44 are a pointer to the first
memory location used by BASIC. 43 holds the
low byte, which is added to 256 times the high
byte (in location 44). On a 64, for example, the
numbers 1 and 8 are contained in the pointer.
And 1+256*8 is 2049, where the BASIC pro-
gram starts. After you press RETURN, you'll see
the following numbers (64 only— VIC, Plus/4,

120 COMPUTED Gazette May 1985

and 16 will be similar):

2049 9 low line link

2050 S high line link

2051
2052

10

low tine number
high line number

2053
2054
2055

143
65
66

token for REM
ASCII value of A
ASCII value of B

2056
2057
2058

zero: end of line

two zeros: end of program

The line link points to the beginning of the
next BASIC line. Like the pointer at 43-44, it is
stored in low/high format. The same formula
tells you where to find the next line, 9 + (8*256),
which is 2057. If there were another line in
memory, 2057 and 2058 would contain the line
link.

The line links work like stepping stones —
the first link points to the second, the second
points to the third, and so on. You'll always find
a zero in between lines, just before a line link.
The last line link in the program points to the
first of two zeros. So, three zeros in a row mark
the end of the program.

Putting zeros into the first line link will pre-
vent users from listing or running the program,
unless they know the correct POKEs:

1. List the program to make sure it's in
memory.

2. Enter B - PEEK(43) + 256*PEEK(44):
PRINTB. Write down the number.

3. Now PRINT PEEK(B), PEEK(B + 1) and
write down the two numbers.

4. Type POKEB,0:POKEB+1,0 and LIST.

The program's gone. But you can save to
tape or disk and load the seemingly invisible
program back into memory. A couple of
POKEs — the numbers you wrote down — and the
program is back.

Numeric Password

There are a couple of variations on the line link
changer. Type NEW and enter this program:

10 PRINT "PASSWORD": INPUT S,L,H: POKE S,L:

POKE S + 1,H
20 PRINT "HELLO."

LIST it, to see that the program is in mem-
ory. Now, enter this line in immediate mode:

B = PEEK<43) + 256*PEEK(44):FORJ = B + 5TOB + 80:
PRINT - JVPEEKfJ- 1) =0);:NEXT

The screen should fill with a lot of zeros
(and a few other numbers). Write down the first
number that's not a zero. Call it the key location.

Let's say it's 2090 (if it's something else, use that
number instead). That means the line link for the
next line (line 20) can be found in 2090-2091.
Next, enter PRINT PEEK(2090), PEEK(2091) and
write down the numbers. In this example, they
might be 57 and 8, depending on the spacing in
lines 10 and 20.

Finally, POKE 2090,0: POKE 2091,0 (if your
key location is different, use that number instead
of 2090). Changing the line links to zero makes
listing past that point impossible. If you list the
program, all you'll see is line 10. If you know the
three number password, you can make the pro-
gram work.

Type RUN and enter the three numbers,
separated by commas. In this example, your
password would be 2090,57,8. The POKEs in line
10 fix the line link, restoring the program to
normal.

An Infinite Program

Remember that locations 43 and 44 point to the
first line link, and the first line link points to the
second. What would happen if we changed the
first line link to point to itself? Let's try it. Type
NEW and enter a short program:

10 REM FIRST LINE
20 REM SECOND LINE

FL=PEEK(43)+256'PEEK<44):PRINTFL,PEEK<FL),
PEEK(FL+1)

Write down the three numbers and then en-
ter POKE FL, PEEK(43): POKEFL + 1, PEEK(44).
The first line link now points to itself. Try to list
the program and you'll see line 10 printed over
and over. After listing the first line, the computer
checks the line link for the next line in memory.
The link points to itself, so the first line is listed
again and again, almost as if the program were
infinitely long.

To get the program back, change the line
link back to what it was by POKEing the num-
bers you wrote down.

Let's take this a step further. As we saw
above, a REM followed by a quotation mark and
reversed T's (working as deletes) can make a line
invisible to someone hying to list it. If you use
this trick to make the first line invisible, then
twist the line link to point to itself, LIST will
seem to be disabled. The computer will print an
infinite number of invisible lines.

A combination of the above techniques can
protect your programs from most prying eyes.
These tricks are not perfect, however. A good
machine language programmer could probably
bypass these routines. If you can invent a pass-
word protection system, someone else can prob-
ably figure out how you did it. The best program
security is still a lock and key. ©

Bug-Swatter:

Modifications And Corrections

• In line 60 of "Address File" (February), the
GOSUB should be changed to GOTO. Otherwise,
the return addresses build up on the stack, even-
tually causing an out of memory error.

• "Free VIC" from Machine Language For Begin-
ners (April) may not work correctly, because the
VIC has 22 columns and the program tries to
print at column 30. Make the following change:

858 DATA 3,160,16,162,0,24

• There are no known corrections for "Auto
Line" (December 1984). However, the article in-
correctly described a method for loading Auto-
matic Proofreader from Auto Line. If you load a
longer program from a shorter one, the pointer to
variables is not updated. To use the programs to-
gether, load and run Auto Line. Next, from im-
mediate mode, load and run Automatic
Proofreader,

• Many readers have suggested that "Magazine
Indexer" (January) and "Address File" (February)
would be more useful with a printer option. The
following program will read addresses from disk
and print them on a Commodore printer. Note
that this is a separate program, and should not
be added to Address File.

10 OPEN2,8,2, "0:ADDRESSES, S, R" :0PEN4,4:B=

6
20 INPUT#2,A
30 FORJ=lTOA:FORK=lTOB
40 INPUTi2,AS:PRINT#4,A$; :PRINT#4, "

{3 SPACES}";
50 NEXTKsPRINT#4:NEXTJ
60 CLOSE2:PRINT#4:CLOSE4

For Magazine Indexer files, change the filename
in line 10 to "0:ARTICLES,S,R" and change B = 6
to B — 1. For both programs, tape users should
change the first statement in line 10 to
OPEN2,1,0 "filename".

• If- you own more than one disk drive, you may
have found that "Disk Auto Load" (November
1984) works only with drive number eight.
Reader Andrew W. Gaunt suggests the following
changes:

687 DATA3,3,165, 186, 170, 160,0,32 : rem 88
7280 DATA162,200,160,29,32,189,255,165

:rem 139
7288 DATA186, 170,160,255,32,186,255, 169

:rem 209

Also, the checksums should be changed in line
25 (from 8554 to 8728) and 45 (from 42577 to
42751). With these modifications, the program
loads and runs from the disk drive containing the
boot program,

• All versions of "Forbidden Crypt" (February)
work as listed. The 64 version, however, does
not clear the variable TC between games. When
a game ends and a new one begins, you may not
have to gather treasure from all four rooms of
level one. If you consider this a bonus, it does no
harm to leave it in the game. Or, change line
612, adding a colon and TC = after the
WAIT198,!. m

Dreams CAN come true!

..USE

UkUX-JJUL. JfciatJfcM|_ta«t
c»it...ff««i,..Hi«k< S'lf.i?

Back in June of 1983, Kelvin Lacy
had a dream. He dreamed of creating
one integrated program that would
include a spreadsheet, business
graphics and a database. A program
with the power of Lotus 1-2-3. On the
Commodore 64. People laughed! He
had just finished OmniWriter, to be
marketed by HESWARE. Ignoring the
skeptical, he started on VIZASTAR,

Now, after 15 months, his dream has
come true. VIZASTAR has a full-
featured spreadsheet, as good as
Multiplan. But much faster— faster
than many spreadsheets on the IBM
PC! it is written 100% in 6502
machine language code and is
ALWAYS in memory. It is menu-
driven, using the latest techniques in
user-friendliness. It is compatible with
virtually all printers and word
processors. Up to 9 windows can be
open simultaneously, anywhere.
Remarkably, 10K of memory is
available for spreadsheet use.

The database is equally impressive.
Create file layouts by simply painting
a picture of the layout on up to 9
screens, showing where a field starts
and ends; VIZASTAR does the rest.

Imagine the power of a spreadsheet
integrated with a database. Now add
graphics — bar, line, and multicolor
pie and 3-D "skyscraper" graphs, You
could access a customer's profile in
the database, transfer the data to the
worksheet, and let it calculate
discounts, sales tax etc. and then
transfer the updated data back to the
database. Open up a window
anywhere and display a graph of your
data, instantly. This integration is the
key to VIZASTAR's power-the first
and only program of this kind on the
C-64. All commands can be
automated, so you can "program"
your own applications and run them
with one keystroke.

VIZASTAR includes a cartridge, a 1541
diskette with a backup, reference and
tutorial manuals. VIZASTAR is ONLY
$119.97. We are so positive you will be
delighted with VIZASTAR that we offer a
15day money-back guarantee. Try it risk-
free! Compare VIZASTAR with any other
spreadsheet or database.
