Doesn't this stuff drive you nuts? In RPG IV, you can have Program A call Program B, which calls Program A recursively. When you create the recursive program, specify ACTGRP(*NEW). Then ILE creates a new activation group each time the program is called. Hence a new "data segment" is created, the cycle starts over, etc. Bob Cozzi www.rpgiv.com ----- Original Message ----- From: Chris Bipes <ChrisB@cross-check.com> To: <MIDRANGE-L@midrange.com> Sent: Thursday, July 08, 1999 9:49 AM Subject: RE: Recursive Calls > We use a parm to tell when we call program b from another program, say a. > We disable the function keys in program b when not called from a menu but > from another program using a function key.
