Sayswho? Says ANSI.
Specifically,subcommittee X3B8 of the American
National Standards Institute (ANSI) says so. The fact
isall ElephantIm floppies meet or exceed the specs
required to meet or exceed all their standards.
Butjust who is "subcommittee X3B8" to issue such
pronouncements?
They're a group of people representing a large,
well-balanced cross section of disciplines—from
academia, government agencies, and the computer
industry.People from places like IBM, Hewlett-Packard,
3M, Lawrence Livermore Labs,The U.S. Department
of Defense, Honeywell and The Association of Com-
puter Programmers and Analysts. In short, it's a bunch
of high-caliber nitpickers whose mission, it seems,in
order to make better disks for consumers,is also to
make life miserable for everyone in the disk-making
business.
How? By gathering together periodically (often,
one suspects, under the full moon) to concoct more
and more rules to increase the quality of flexible
disks.Their most recent rule book runs over 20 single-
spaced pages—listing, and insisting upon—hundreds
upon hundreds of standards a disk must meet in
order to be blessed by ANSI. (And thereby be taken
seriously by people who take disks seriously.)
In fact, if you'd like a copy of this formidable docu-
ment, for free, just let us know and we'll send you
one.Because once you know what it takes to make
an Elephant for ANSI
We think you'll want us to make some Elephants
for you.

BASIC
I hav e s ome book s t hat show, I t hink ,
programs in Microsoft BASIC. I've tried to
list them, but can't. I gather ATARI BASIC
handled s trings muc h differently . H o w
can I translate f rom Microsoft?
I hear that PET BASIC is very s imilar
to A TA RI BASIC. Co u ld y o u d o s ome
articles s howing us beginners just what
changes must be done to translate other
BASICS s o t h e y w i l l r u n o n A TA RI
machines?

FORTH
I think y our magazine is great. I especially
like t h e Fo r t h Fac tory , bec aus e mo s t
FORTH programs previously writ t en use
no graphic s o r sound, so I really had no
motivation to sit down and learn the lan-
guage on my ATARI. Now I think FORTH
may ev en s et me t o writ in g s ome fast,
sophisticated games.

I enjoy ed t he fi rs t issue o f A NTI C c on-
siderably, and typed in the (Kid's Korner)
program. I found it amusing, but do be-
lieve that a person's name deserves even
more respect. I composed t he f ollowing
BASIC program, and hope y our readers
like it.

MONEY PROBLEMS
I got my ATARI 800 last Christmas, and
use it mos tly f o r wo rd processing wit h
Letter Perfec t, a n d w i t h o t h e r c anned
software. I fi nd the ATARI Personal Fin-
ance Program is diffi c ult to work with, in
a single disk system, and "bombs " when-
ever you attempt to run data accumulated
over more than t wo months. I t displays
"no rec ov erable s y s t em e r r o r . " N o w
what?

MONITOR KIT?
Please a v o id b e in g t o o "s imple. " T h e
ATARI is rapidly generating a group o f
"middle" programmers who need help ex-
panding t heir systems. Fo r example, I 'm
especially interes ted in: print ers , in t e r-
faces and cables; c onv erting a TV int o a
monit or (kit?); using ATARI PASCAL wit h
only one disk drive.

RADIO LINK
I am an amateur radio operator, AA5R. I
am now using a home made modem and a
v ariation of the baudot terminal emulator
progra m (f rom t he ATARI 850 Interface
Manual) t o rec eiv e radio-telety pe mes -
sages from around the world. This has the
excitement of telephone interfacing, but
wit h no telephone bill!
There hav e been f e w artic les pub-
lished related to the use of the ATARI in
the radio hobby. Can you cover it in some
future issue?

CHICKEN G AME
I really enjoyed Chicken (issue #1). It's the
best action game I've ever seen written in
pure BASIC. Would y ou do an artic le on
using assembly language wit h BASIC in a
future issue?

The Chic k en program alone makes t he
price o f ANTI C wort hwhile. We s aw it
running at the Family Computer Center in
Berkeley, Michigan, and my son wouldn't
let me res t unt il I f ound a c opy o f the
magazine.
Robert Lambeck
Southgate, MI
I am new to this c omputer world, and am
having t ro u b le w i t h t h e Chic k en p r o -
gram. It runs to "intializ ing," then posts an
error message 8 at line 40. I 'm us ing an
ATARI 400 wit h 32K and a BASIC c ar-
tridge. What's my problem?
Tom Miller
Northridge, CA
The Chicken program runs as listed in issue
The majority of errors stem f rom mis-
typing DATA statements. Look for transpo-
sition errors (214 instead of 241). Another
common error is substituting a period() for
a comma(,). We will be providing a program
to help you fi nd your typing errors, expect it
in issue #3.

EDITORIAL
We thank those of you wh o let us k now
y our fi rst impressions of ANTIC. Some re-
sponses appear here, i n o u r fi rs t I / O
Board, wh a t some ot her magazines c all
t heir "letters t o t he edit or" page. I / 0 is
c omputer jargon f or Input/Output.
We read all of the letters that came in,
and reproduc ed some representative ex-
amples. We invite all of you, beginners or
advanced, to continue to let us k now how
we have helped (or hindered!) y our use of
the ATARI.
There are t wo other things we hope
you will do. First, if you contact any of our
advertisers, tell them you saw their ad in
ANTIC. Second, i f y our c omputer store
does not yet carry ANTIC, ask them to do
so. We dis tribute nationwide.
