Re:  DOSCALL0.ZIP - a free implementation of the DOS >= 3.3 CALL function


Recently gmcmanus@dsac.dla.mil noted a problem that some users have with
older versions of DOS.  The problem being one of needing the call function
found in later versions of DOS.

Gene's solution was to simply write a C program named CALL.C, compile it,
and post it.  At first I thought, uh oh, but then I tested it and found
that it only used about 14.5k of memory according to mapmem.  This was
impressive since I have tried to write similar code, using the C system
function, and couldn't get memory usage below 70k.

Hat's off to Gene and his 1988 Microsoft C compiler, however he does it!

Now, here's the *better* solution.

First, I've written a CALL.BAT file which contains the following lines:

        @echo off
        %1 %2 %3 %4 %5 %6 %7 %8 %9

Meaning that, as long as I have no more than 8 parameters to pass, all
will be fine.  Of course, the CALL.BAT file is compiled into CALL.COM
using the BAT2EXEC program from PCMAGazine.  (which I got from Garbo,
due to Prof. Salmi making it available;  gotcha Timo!  :)

Best of Skill!       :)
