Re: RE: Passing parameter back to calling CL

will do it. If you don't do it this way you'll have to do something ugly like passing character values or convert to decimal in the C (by assigning to an appropriate decimal variable) and copy the correct number of bytes into your caller's storage. Doesn't C suck?

No, C doesn't suck. But it does seem like you guys are going through a lot of gyrations to do something very simple: get a return value from a C program. All you want is a number, so return one:

  int rrn;

  return (rrn);

Done. Easy. Every C function can return a value, including main(). All you need to know is, "What is the value of the last executed command?" The shell can find that out for you very simply.
