Re: How does COBOL detect a recursive call?

That, Victor, could still require "IS RECURSIVE" on the PROGRAM-ID to avoid the abend with the IGZ0064S message (because the "handler" is invoked from the same program), depending the linkedit/binder RENT/REUS values. So it doesn't make it any simpler at the level of the mechanics. Also, when

Re: How does COBOL detect a recursive call?

Chuck, Just another weird suggestion which may [or may not] work in your case - why can't the very SAME entry point also serve as the error handler? I mean, it is being called with a parameter list, so by parsing the input parameters can't it determine the exact reason for call? And if it's

Re: How does COBOL detect a recursive call?

The wherefores of using a main program and an ENTRY versus 2 programs is a political battle I am not prepared or willing to fight. When initially assigned this project I was hoping that my Systems status within the company would grant me some carte blanche in how I engineered the solution but,

Re: How does COBOL detect a recursive call?

Bob, Since John is working with a stripped down copy of my program I resurrected the copy of the program with my debugging displays in it where I had already coded the displays for the two addresses you asked about. Displaying the main entry point address, that is, the name of the program as
