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.

Maybe this?

if (DosGetInfoBlocks(&tib, &pib))
return 5;

e = pib->pib_pchenv;

I used pchcmd instead, and now parameters are working!

New version of pdos.zip at pdos.org runs the test
program built by makefile.wat, including parameters.

You can't allocate memory or open files yet though.

Unless I'm missing something, I don't think that
will be difficult to add (to doscalls.c in pdos/src)
tomorrow.
