Multithreading inside COBOL program

Is it possible to multithread a set of process (independent subroutines)
inside a COBOL program like what we do in PL/1 or C.

The answer could be Yes or No, or Maybe.

Please describe exactly what you would like to achieve, and why multi-threading is your best tool, and how you could do it in PL/I and C, please.

I have a requirement where a set of independent subroutines that can be spanned out independently inside the program to be executed without going for a linear execution.At some point I can reconcile the results of both and proceed linearly.

I read this article in IBM (multithreading C main program and two COBOL programs)

Are you running under AIX?

No it is not in AIX...

I would like to know if it is feasible in zO/S.

Follow Peter's link to know.

I don't understand if the things are "independent" why you feel you need to have them in one program? I don't think your explanation of the requirement has been sufficiently full to provide a great deal of help to you.

Hello and welcome to the forum,

I suspect there is no business reason to do this. . .
