Posting-number: Volume 9, Info 1
Archive-name: intro
This is the first of three introductory articles about comp.binaries.atari.st.
This one describes how to submit binaries to the newsgroup. A companion
article lists all previously-published binaries, and a third article explains
how to retrieve and unpack binaries posted by others.
I am always looking for suggestions on how to improve the usefulness
of the newsgroup, and can be contacted as listed below.

--------------------
Subject: Submitting binaries for publication
Items intended for posting or queries and problem notes should be sent to
atari-binaries@panarthea.ebay.sun.com. If you are on a UUCP-only site, you
can send them to ?backbone?!sun!ebay!panarthea!atari-binaries.
If you're in Europe, you can send binaries to the European submoderator,
Jan-Hinrich Fessel, at unido!atari-binaries (or, if you're a masochist,
atari-binaries@unido.informatik.uni-dortmund.de.) He will test them and
forward them to me. Submitting to him saves net bandwidth, so it's
encouraged.
If you want verification of arrival, so say in a cover note, or at the
beginning of your submission, if it is small. I try to verify that a
program works, and if I can't get it to work, I may hold up posting it
for a couple of days. Please note that, except in rare cases, software
without documentation will not be published. The backlog from receipt
to posting varies from one to four weeks depending mostly on the set
of submissions currently in my queue.
If you are submitting both sources and binaries, please send the two
separately. If I have to separate your sources from your binaries by
hand, your submission will most likely sit on the back burner for a
while.
Also, as of volume 8, I will only accept binaries packed with an archiver
for which source code is widely available. For the time being, this pretty
much means arc and zoo. If you want to use a nifty new archiver, make the
source code available to the public (posting to comp.sources.atari.st is
fine.)
--------------------
Subject: The structure of comp.binaries.atari.st articles
Each posting in comp.binaries.atari.st is called an "issue"; there are
roughly 100 issues to a volume. The division is arbitrary and may vary.
There are two types of articles in comp.binaries.atari.st: binaries and
"information postings." They can be distinguished by the subject line:
Subject: v09INF2: Index and other info
This first word in the title identifies this as the third info posting of
volume six. Similarly, the subject line shown below:
Subject: v09i081: crayemu -- Run Cray-3 programs 30% faster
identifies this as the 81st binary article in Volume 9. Large programs are
broken up into smaller pieces, and have subject lines that look like
this:
Subject: v09i041: stvme -- Turn cartridge port into a VMEbus part04/18
Certain information about the system configuration required to use the
program is given on the keywords line.
Keywords: uuencode, 1meg, medium, high
This means that the program requires at least one meg of RAM and runs in
medium or high resolution. Following is a list of keywords; new ones may
be added as needed. They are mostly self-explanatory.
uuencode - program is uuencoded (UNIX uudecode required to unpack)
uue - program is uuencoded (ST uud required to unpack)
arc - program is archived (arc required to unpack)
zoo - program is a zoo archive (zoo required to unpack)
high - high resolution
medium - medium resolution
low - low resolution
1meg - needs 1 meg of RAM
The first few lines of an article are auxiliary headers that look like this:
Submitted-by: jackt@atari.UUCP (Jack Tramiel)
Posting-number: Volume 9, Issue 80
Archive-name: free
The "Submitted by" is the author of the program. If you have comments about
the binaries published in comp.binaries.atari.st this is the person to contact.
When possible, this address is in domain form, otherwise it is a UUCP bang
path relative to some major (backbone) site.
The "Reply-To:" header line in the article's main header points to the
submitter, to make commenting about binaries easier.
The second line repeats the volume/issue information for the aide of notes
sites and automatic archiving programs.
The Archive-name is the "official" name of this program in the archive. Large
postings will have names that look like this:
Archive-name: desktop/part01
Since most archive sites run UNIX, articles are given UNIX-style filenames
rather than ST-style filenames. I do make an effort to keep filenames to
8 characters or smaller, however.
--------------------
Subject: Reporting and tracking bugs and patches to postings
Updates to programs are usually announced in comp.sys.atari.st. When
large changes are made to a program, the entire thing will be reposted
to comp.binaries.atari.st.
To report bugs, contact the person listed in the Submitted-to header.
Often there is a contact address in a README file, too. I do not maintain
the programs I moderate, so don't send your bug reports to me.
If the program documentation mentions some file that isn't included in
the posting (for instance, a font editor's documentation might refer to
some sample fonts), contact the submitter, not me. I post articles in
their entirety, so if it isn't posted, I probably don't have it.

HOW TO USE COMP.BINARIES.ATARI.ST
by Steven Grimm
Last update: October 13, 1989
A preliminary note, for those of you who know most of the
below already: the official archives on panarthea are NOT
reachable via anonymous ftp from the Internet. Read on for
information about accessing them by mail, or see the table
at the end of this document for a list of alternate archive
sites.
_1. _W_h_a_t _a_r_e _b_i_n_a_r_i_e_s?
Binaries are files that contain information other than
normal text. Usually, a binary that is posted to the net
will contain executable (program) files. Binaries are dis-
tinct from _s_o_u_r_c_e_s, which are the human-readable text files
that are interpreted by a computer and used to produce
binaries. Sources can be modified with relatively little
effort, and are usually pretty easy to read. Binaries are
not intended to be viewed by a human.
_1._1. _U_u_e_n_c_o_d_i_n_g
The programs which transfer network news messages (and
electronic mail) are not always capable of handling a pure
binary file. They are designed to handle textual messages,
and the odd symbols and characters in a binary cause them to
become confused, and often to mangle the binaries. To avoid
this problem, a method called _u_u_e_n_c_o_d_i_n_g is used. Uuencod-
ing translates a binary file into text characters, so that
the news and mail transport programs won't mess up. The
disadvantages are that uuencoded files are about 30% bigger
than the raw binary files they represent, and that you have
to go through one extra step to get the binaries to work on
your computer.
_1._2. _A_r_c_h_i_v_e_s _o_r "_a_r_c _f_i_l_e_s"
Usually, a program will need more than one file to work
properly. The extra files might be data files, help files,
or maybe some instructions for the user. In order to easily
package multiple files together in one binary file, a pro-
gram called "arc" (short for "archiver") is used. Arc also
compresses all the files as it packages them, so that the
arcfile take up less disk space (and takes less time to
download!) than it would if its contents were just thrown
Using Binaries -2-
together.
To confuse matters even more, a new archive program
called "zoo" can also be used to achieve the same effect.
Zoo is superior to arc in some respects, slightly inferior
in others. Unfortunately, you can't unpack a zoo archive
with arc, or vice versa.
_1._3. _U_S_E_N_E_T _a_r_t_i_c_l_e_s
The USENET has groups designed especially for transmis-
sion of binary files. They are usually called something
like "comp.binaries.x," where x is the type of machine that
the programs will run on. For Atari ST owners, the group to
watch is comp.binaries.atari.st. Most of the binaries
groups (including the Atari binaries group) are _m_o_d_e_r_a_t_e_d,
which means that you can't send a program directly to every-
one on the network. Instead, you send it to someone in
charge of the group (the _m_o_d_e_r_a_t_o_r), who makes sure that
your program works and contains the proper documentation (or
that the lack of documentation is announced), and that it's
in the correct format to be sent out to the rest of the
USENET.
One of the restrictions of the USENET is that articles
can only be a certain length. If a binary is longer than
that, it must be split up into several parts, each no longer
than 45000 bytes or so. This introduces yet another obsta-
cle to people who want to transform the articles into a use-
ful form, but it can't really be helped until the USENET
starts running much more advanced news transmission
software. Also, some particularly long programs may be
posted over the course of several days; otherwise the net
would be overloaded with lots of huge messages, and people
would complain.
USENET binaries are grouped into _v_o_l_u_m_e_s, each contain-
ing about 100 articles. This is to make life easier for
people who are trying to keep track of which articles have
been posted. When a new volume is started, the moderator
will usually post introductory articles, including a list of
previously published articles.
_2. _H_o_w _d_o _I _g_e_t _b_i_n_a_r_i_e_s?
There are two ways to get binaries: first, by reading
the USENET newsgroup comp.binaries.atari.st; you will see
new articles within a week (usually much less) of the time
they were sent out by the moderator. If, for some reason,
your site doesn't receive comp.binaries.atari.st, or if you
want to look through previously posted articles, site
panarthea.ebay.sun.com has all the binaries stored in its
archives.
Using Binaries -3-
The other way to get binaries is to request them from
panarthea's archive server. The archive server is a program
that intercepts incoming mail messages and looks for com-
mands inside them. You can tell it to list the available
binaries, give you help, or send whichever files you're
interested in. The requested files will be mailed to you.
One thing to be careful of is that multi-part postings
aren't placed in the archives until all their parts have
been sent out to the USENET at large. This is to prevent
people from requesting all 99 parts of a program the first
day it appears, thus overloading the net and defeating the
purpose of piece-by-piece posting.
To find out more about the archive server, send a mail
message containing the word "help" to archive-
server@panarthea.ebay.sun.com. Talk to an administrator at
your site if that mail address doesn't work. If you don't
get any response from the archive server within a few days,
something may be wrong; mail archive-
manager@panarthea.ebay.sun.com to report the problem.
There are other archive sites, too, such as
terminator.cc.umich.edu; they contain most of the
comp.binaries.atari.st software as well as some additional
programs that have not appeared on the newsgroup. Some
sites, such as terminator, also offer something called
"anonymous ftp" if you're on the Internet. Say "ftp
terminator.cc.umich.edu", and if you connect, use
"anonymous" for a username, and your username for a pass-
word. See the ftp documentation at your site for more
information. A recent, but possibly incorrect, list of
alternate archive sites appears at the end of this article.
Please send me mail if you know of any that aren't mentioned
here, or if my list is incorrect. Note that panarthea does
not offer anonymous ftp, as it's on a network that's segre-
gated from the Internet.
Panarthea also offers an "auto-index" service, for peo-
ple who don't have access to the USENET groups. If you
request autoindex service, you will receive copies of the
archive-server's index files for the binaries and sources
groups whenever new files are added. Note that if your site
gets comp.binaries.atari.st, requesting autoindex is point-
less and a waste of net bandwidth. Send mail to autoindex-
request@panarthea.ebay.sun.com if you'd like to sign up.
_3. _H_o_w _d_o _I _d_e_c_o_d_e _t_h_e
_b_i_n_a_r_i_e_s?
As stated above, turning binaries from USENET articles
into a more useful form can be a multi-step process. At the
least, you will need the uudecode program; it is standard
software on most UNIX|- systems and is available in a couple
_________________________

of forms on the Atari. Versions for other operating systems
do exist, and can certainly be written with little effort.
Arc is available for UNIX and other operating systems, but
is not standard software. In any case, you will want at
least arc on your Atari.
A version of uudecode written in ST BASIC is available
in panarthea's archives (see above). It is in volume 1 of
the comp.sources.atari.st directory (note that that's
_s_o_u_r_c_e_s and not binaries). Once you have that, you should
get the files "arc," "arcdoc," and "uucode" from volume 1 of
the binaries directory. They contain the arc program men-
tioned earlier, its documentation, and a much better, faster
version of the uudecode program.
Use the BASIC program to uudecode the two encoded
files; then use arc to unpack the better version of
uudecode. (Arc is documented in "arcdoc.") Note that if
you're reading news/receiving mail on a computer (such as a
UNIX system) that already has uudecode, you can skip most of
this; you will probably just want to uudecode arc there,
then download it (using kermit, xmodem, or your favorite
transfer protocol - consult your site's administrator and
your Atari communication package's documentation for more
information. Remember to use binary mode when downloading
arc files!)
So far, everything has been small enough to fit in one
piece, but you will almost certainly want to try something
larger eventually. The Atari "uud" program (whose source
code, also suitable for compilation on UNIX systems, is
available in the sources archive) is capable of easily
decoding multi-part uuencoded files. Near the top of each
part (except the first) will be a line like
begin part c foobar.uac
Rename each file (except part 1, which can be named
"part01" or just about anything else) to the name at the end
of this "begin" line, in this case "foobar.uac". Then run
uud on the file containing part 1; it contains instructions
to cause uud to look for the other parts. If you have a
text editor or a UNIX style cat program, you can just stick
all the parts together in order and run uud on the resulting
(big) file; it will try to go on in the first file if it
can't find the next part in a separate file. Note that uud
won't warn you if it's overwriting an existing file, so
don't give any of the parts the same name as the file that's
being extracted from them!
If you don't have uud or would prefer to decode your
binaries on your larger news computer, the procedure is
somewhat more complex. Plain vanilla uudecode doesn't know
Using Binaries -5-
about multi-part uuencoded files, so you have to fool it
into thinking that everything is in one part. First, stick
all the parts together (using cat on UNIX). Edit the
resulting file. Now remove all the extraneous lines of text
in between the parts -- this includes mail headers, any
text, lines of the form "include foobar.uad," "table" lines
and the lists of characters following them, and "begin"
lines other than the one at the beginning of part 1. Once
you have converted all the parts into a big uuencoded mass
(with no blank lines!), the regular uudecode program will
work.
Obviously, this is something of a hassle, and the
recommended procedure is to try to install uud on your large
computer. You'll usually want to minimize the amount of
data you have to send to your Atari, since you'll most
likely be downloading it at a relatively low speed, and the
uudecoded .arc file is the smallest thing you can download.
Zoo is available from the archives. It is simple to
use; refer to the documentation included in zoobin.arc (yes,
you need to use arc to extract zoo!) for more information.
The uudecoding process is the same for zoo and arc files.
Most archives contain documentation; refer to the
instructions in a specific program for usage information and
the like. If you have problems with a particular program,
send mail to the submitter (listed near the top of each
part.) The moderator doesn't have time to become very fami-
liar with all the programs that are posted, so the submitter
will probably be much more helpful.
_4. _L_i_s_t _o_f _a_r_c_h_i_v_e _s_i_t_e_s
Note: I have not verified these, so this list may be
wrong. Mail servers usually respond to the word "help"
alone in a mail message. Some of the sites listed below may
not contain full archives of comp.binaries.atari.st, and
some may have other files.
