IIRC, the programmer now has all the tools/features needed to handle conditions that would have resulted in an abnormal termination in anchient times.
Some of this behaviour is by default (especially in C programs), and sometimes gives our produciton scheduler folks fits. (If there is no visible ABEND, then there is no visible exception, and the alarms are not tripped.) Indeed, we may soon have to drop 'abend' from our lexicon and use some deritive of 'unhandled condition'. For sure the programmer has a greater responsibility to insure that the program behaves as expected in unexpected situations. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of McKown, John Sent: Thursday, April 14, 2011 10:46 AM To: [email protected] Subject: Re: Cobol and SMS question > -----Original Message----- > From: IBM Mainframe Discussion List > [mailto:[email protected]] On Behalf Of Shmuel Metz (Seymour J.) > Sent: Tuesday, April 12, 2011 12:54 PM > To: [email protected] > Subject: Re: Cobol and SMS question > > In <listserv%[email protected]>, on 04/12/2011 > at 09:54 AM, Paul Gilmartin <[email protected]> said: > > >Doesn't this require also that the programmer provide an exit to > >divert the ABEND S%13 which otherwise results from an OPEN failure > >and causes program termination. > > Your question has an assumption contrary to fact.

IIRC, the Sx13 abend happens when there is a DD, but there is something "wrong" with it. Like OPEN for INPUT on a member which does not exist in the PDS. Or invalid or missing DCB information (eg: LRECL=80,RECFM=FB,BLKSIZE=90 in the JCL). Or "dataset not on volume". -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
