I would like to get a return code from a executable file (.cmd or .exe)
when I execute the file from within my 'C' code.

On a Unix system, this is not a problem since '/bin/sh' will return
the status of the last command executed or the return code given with
a shell 'exit' command.

For OS/2 (MicroSoft C 6.0) 'cmd.exe' does not return an exit status of
the '.cmd' or '.exe' file that it executed.  There is no 'exit' equivalent
of '.cmd' programming to force a return code.

Another problem (I think, but am not 100% sure of) is that the 'system'
procedure return a zero if the 'cmd.exe' is executed successfully and
non-zero if it isn't.  It does not return the return code it gets from
'cmd.exe' from the 'DosWait' procedure.

Does anyone have any ideas on how to overcome this problem?

Kludge solutions include (the child process being executed) writing to
a file, shared memory, pipe, semaphore, etc. and have the parent check
that output after the child is complete.

Anything better????
