Re: Passing Parameters Back to a S/36 Proc

I have often passed parameters to a program from a /36 procedure, such as:
CALL PGM(PGMA) PARM('PARM1' 'PARM2'), or
CALL PGM(PGMA) PARM(?1? ?2?)
where the parameter conditions something in the callee (PGMA).

Now I would like to be able to receive information from the callee to condition something in the /36 procedure.

If 8 bits suffice, you can use external indicators.


I tried the second example, but the call resulted in a pointer error.

Using the local data area works as an interface between the 36E and an RPG IV program, but not if the program (PGMA, for example) is called by another RPG IV program as the LDA is not updated until the caller ends.

I think an explicit OUT operation would get the infomation back to you.

All this is from very old memory.
