Well, around here it would do one of two things: 1) issue a DISPLAY UPON CONSOLE 2) then abend itself or 1) Ignore the return code 2) abend on the next I/O statement or 2) go into an infinite loops trying to do I/O while getting (and ignoring) the return code that says that the I/O failed or 2) get a return code on the next I/O statement and issue a DISPLAY UPON CONSOLE followed by an abend. The only real option for batch that I can think of is to ABEND or return with a bad return code. Well, I guess it could "lie" by just ending with an RC=0 indicating that "all is well!" until some user noticed that a report was missing or some such thing. Also, depending on the nature of the application, an nice ESTAEX type exit would be appropriate. I.e. something interactive like TSO. Wouldn't it be nice if your TSO session ended if some program abended that you were trying to run. Maybe like a S913 abend when somebody tries to edit a dataset that they cannot READ. -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology The information contained in this e-mail message may be privileged and/or confidential.
