AS400 - Passing and calling and RPGLE from a non-ILE Cobol program

Question

A non-ILE Cobol program is calling and passing parameters to an RPGLE program. The Cobol passes a non-sorted area to RPG, RPG sorts that area with SORTA and returns the sorting area back to the Cobol.

1. Passing parameters between non-ILE Cobol to RPGLE - Is that possible?
2. What are the constrains (size of parameters, number of parameters)?
3. Any compilation restrictions?
4. Any other tips are welcome:)

RPGLE code:

Answer 1

Yes, it's possible to call an ILE RPG program from any COBOL program.

You can pass up to 255 parameters on a program call.

There are no compilation restrictions. Compile both programs normally.
