My 32-bit OS/2 applications rely on this parameter on the stack:

__intstart proc
         mov eax, [esp+16]
         push eax
         call __start


in order to get access to the command line.


However, I would like to not have to rely on either
the stack or register at entry for my OS/2 applications,
so I would like an alternate way of getting that
information.

(that way I can provide my own stack format and no
register values, in PDOS-generic form suitable for
running PDOS-generic apps).


For OS/2 16-bit I was able to do this:

#ifdef __16BIT__
         {
             USHORT seg, offs;

             if (DosGetEnv(&seg, &offs) != 0)
             {
                 p = "\0"; /* two NUL characters */
             }
             p = (char *)(((unsigned long)seg << 16)
                          | offs);
         }
#endif
         argv[0] = p;
         p += strlen(p) + 1;


But that function doesn't seem to exist in OS/2 2.x.

"The" documentation says to use a newer replacement, but
doesn't specify what that might be:

http://www.edm2.com/index.php/DosGetEnv


Until this is resolved, the new pdos.zip at pdos.org
is capable of running pdptest.exe built with makefile.wat,
but it doesn't print the parameters.

Any idea what options I have?

Thanks. Paul.
