Or, as the programmers at our shop would do: SPACE=EAT-EVERYTHING-IN-SIGHT-AND-CAUSE-OTHER-JOBS-TO-ABEND-BECAUSE-MY-STUFF-IS-IMPORTANT-AND-YOUR-STUFF-ISNT.
Or SPACE=WHAT,ME_WORRY? Or SPACE=I-CANT-BE-BOTHERED-TO-SIZE-THIS-PROPERLY-AND-MY-PROGRAMS-NEVER-LOOP-EXCESSIVELY In many other systems, such as Winblows, everybody gets their own personal "space". And if it is "used up", it doesn't impact others. z/OS shares DASD space. So one bad apple can cause a major problem. Hopefully not in production. But what about for "temp" space? I've had production jobs go down due to no space on the work packs due to a nitwit coding up a job with 30 SORTWKnn DD statements, with SPACE=(CYL,(2000,100)). Because they kept getting "SORT CAPACITY EXCEEDED" and just wanted the <elided> job to run. This was in internal COBOL sort, so dynamic SORTWORK was not possible. IIRC, the problem was their program outputting about 30 million records (a bug). -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets® 9151 Boulevard 26 . N.
