That's interesting, I did not know that! You asked for help and I wound up
learning something, it's going to be  a good day.

I appreciate your response, Howard. In this case, the RETURN-CODE is a COBOL
"thing." I am familiar with communicating with COBOL from RPG using
parms/linkage, but in this case it's an actual program return code rather
than a parm we're passing back and forth. Here is a sample from the COBOL
code:

MOVE 99 TO RETURN-CODE
STOP RUN
.

RETURN-CODE is not a defined variable, so I'm making a tiny assumption that
it's a reserved word and that somehow I can get the value in the calling RPG
program.

(Similarly, in C your functions usually take parameters, but also can return
a value which the calling function can capture, and that is done all the
time, which is why I'm baffled that I can't find how to do this between RPG
and COBOL on the 400.)

Is the RETURN-CODE var an RPG thing? cause usually in COBOL you pass things
like that as PARM values, so in Linkage Section there would be a level 1 (or
some part of a level 1) that you would place a value in, the procedure
division would look like Procedure Division Using 01-Name. (which would be
the 01 name in Linkage). The COBOL program would do it's thing then set some
value in 01-Name and execute a GoBack. The RPG (Disclaimer, I am not an RPG
person) program would have a PARM list containing a positional value name
representing the name 01-Name which would contain the return value.

I'm embarrassed to even ask this question, but I sure can't find the answer.

If I "CALL" a COBOL program from an RPGLE program, how do I capture the
value that the COBOL program has returned using the RETURN-CODE variable?
This is an unbound call.

Seems, oh so simple...but the answer eludes me.

TIA!
