Shel_read doesn't help if you are run from a command line shell which
doesn't launch programs using shel_write. This is another example of
problems caused by ST programs having to live in two different worlds,
the worlds of GEM and GEMDOS. Allowing the startup code to use A0 to
find the basepage address is our way of making it a little easier for
programs to live in both worlds.

Humph. It IS nice to have an OFFICIAL statement on a subject that should
have been settled YEARS ago, but what a statement it is! I guess ATARI
figured that if they waiting long enough, and THEN posted a "standard",
we would forget all the good arguments AGAINST this particular form of
brain-damage. This "new" extended argument spec is Mark Williams form,
with a thin (optional) layer of veneer on it, even after it was flatly
stated that the MWC form WOULD NOT BE ACCEPTED due to the ways in which
is was broken. It appears that politics has won out over technical
merit once again. I don't expect that Atari will change their mind on
this issue (without taking another YEAR to post an answer), but I will
include some information on how the MWC form (at that time) and Atari's
"new standard" are broken. Remember, one of the design goals of this
standard is to be upward compatible with naive programs.

The major problem here is that the NUL separated pieces of the extended
argument list appear to the naive program AS ENVIRONMENT VARIABLES and
my be reshuffled (some shells may SORT them) by that program, modified
and passed on to a program which comforms to this "standard". Now what
happens when this conforming program finds "ARGV=" right up at the front
of the (sorted) environment and THROWS AWAY THE WHOLE ENVIRONMENT. It
does this because the command line length is not the magic value, thus
the "ARGV=" list is not from it's parent, but is still used to terminate
the environment!

Yes, it's official.
I guess I should have put a big header at the top reading:
"THIS IS THE OFFICIAL WORD FROM ATARI ON HOW TO DO THIS ARGUMENT STUFF"
I just wanted to release it to the public so it would get widely used.

Use DCformat to create a bootable floppy (a floppy with boot code on it),
DCformat has a button to click on to do this though I forget exactly what the
button says. Place this boot floppy in drive A, turn the computer OFF, wait
about five seconds, turn computer on. At this point the ST will BOOT the
floppy not the HD, all you have to do now is to run your hard disk boot
program (ICDBOOT.PRG et.al.), install a drive Icon for C:, open up drive C:
and delete the offending .ACCs.
Don't forget to keep the floppy around for next time (yes there will be a next
time :-)

Subject: Has anyone heard of TCOS database?
I have discovered a wonderful ``index card and button'' type database
called TCOS. It's public domain, and supposed to be from Britain, but the
documentation that comes with it gives only a name of a person to contact
but *no address*! I want to send in my $$ and my suggestions for
enhancements. Perhaps someone else has heard of this program and knows
more about it? Here's the info:
TCOS version 1.2
Perfect Evolution 1989
Matthew P. Aubury
Can anyone supply me with more information? Is there a newer version of
the program available anywhere?

Subject: Laserjets and the ST
I recently asked for info from people who had
the new HP Laserjet II-P, and got no responses.
OK, so it's a little soon to expect lotsa people
to have a II-P.
Let me rephrase the question:
Can anyone out there give me some idea of how
long it takes to print a full 8.5 X 11 page of
300 dpi graphics (like with _Calamus_ :-)) on
an HP Laserjet (of any kind)?
My local Atari dealer says that the "sale"
price on the SLM-804 of $1299 might have already
gone by, leaving the $1999 price again. (No way
I want to pay that kind of $$$ !!)
Thanks in advance for any/all info.
Regards,
Bill

As numerous people have pointed out, the operating system clears
all of free memory for each program before loading. Not only that,
but the original ROM TOS does this slowly.
Also as some have pointed out, one solution is to use Pinhead, which
takes control of program loading when it sees GEMDOS clearing memory,
and only clears as much memory as the program needs.
IMHO, a better solution would be for you to get the Rainbow TOS
upgrade. This allows you to speed up program startup selectively (some
programs insist on having all of memory cleared), AND it has lots of
other benefits as well.

You can use the formating program from your old Magic Sac or the
Double Click formatter/coppier program (forget the name).

Transverter reads the entire disk into memory. On a 1Meg machine
there is only about 630K free after the transverter program is
loaded so that is the maximum file size. Note: you can fill up
the disk with files, the 630K rule is for any file, because
transverter only works one file at a time.

Yes, but it isn't quite that simple. After you used Apple file
exchange and have the file on a MAC (BTW Stuffit files work
best), use ResEdit (1.2 or later) to open up the file. ResEdit
will give you a warning along the line of "the file does not have
a resource fork and opening the file will create one." Pick
yes/open/go ahead (whaterver the positive choice is). Now close
the file. All you wanted to do is make a resource fork for the
file. Now use a file maintenace utility and set the file type
and owner to "SIT!", again no quotes or use ResEdit (sorry I
don't use resedit for this and cannot give directions).
