Subject: Running submit files from disks other than A:

For a long time, I have been frustrated by "accidentally" submitting a
submit file while being logged in to a disk other than A:, and having
a magical "$$$.SUB" appear instead of having my submit file processed.
Having gotten my hard disk up, and being forced to leave my system on
floppies and use the hard disk as C: and D:, I found myself really missing
the ability to do submits...
       <interlude>
As a first solution to the problem, I tried going to A: and writing a submit
file that started with:
       c:
just to see if it would take it. Yes! It did let me log in to C: as the
first thing in a submit file, but I still had to go to A: to submit it.
Could there possibly be a way to do a submit on C: without ever leaving C: ?
--- YES !! ---
If you ddt or sid submit.com, you'll notice that the fcb area for the temp-
orary file that submit.com creates ($$$.SUB) has its first byte set to 00...
that means that the $$$.SUB file will always be written to the currently
logged disk, EVEN THOUGH IT HAS NO MEANING UNLESS IT IS WRITTEN TO A: (smart
move, Digital Research...another of many!) SOOOO...my simple solution was
to change that 00 leading byte of the fcb to 01...this causes $$$.SUB to
always be written to A:, no matter which disk the submit is submitted from.
Now I can be on C: and do a submit as easily as if I were on A:.

I hope this helps some of you out there who've been frustrated by the same
problem. Incidentally, the location to patch in the 2.2 SUBMIT.COM program
is: 05BB hex (change from 00h to 01h)
later,
