Water is wet. Spin is releasing a sysout dataset before the step ends. In the special case of segmentation the allocation remains intact. Both cases use SSI to make it JES independent. Oddly enough, you inadvertently admitted that were wrong when you mentioned allocation.
Here's a free clue; when you free a sysout allocation and allocate a new sysout allocation, you wind up with two distinct sysout datasets with distinct dsnames. Even a rude troll with delusions of adequacy should know that. Similarly for segmentation. By the time you do an open, the DSAB, JFCB and TIOT all exist and the dsname is filled in. Even you should know that. -- Shmuel (Seymour J.)

Look up SPIN! I'm tired of repeating myself because I can't fix stupid. SPIN releases a SYSOUT for JES processing. It does NOT affect the SYSOUT DSN in any way. The default is to release all SYSOUT datasets at the end of the job. We don't see any sign of a SYSOUT dataset in SDSF until OPEN. The SYSOUT DSN is most likely built during OPEN but could theoretically be during allocation of the DD. Once a sysout dataset has been freed, the DDN no longer exists and the SYSOUT DSN is no longer available. The new allocation will cause a new SYSOUT DSN. This has nothing to do with SPIN! You refuse to learn anything, so I've had enough of discussing this topic with you. You go far beyond incompetence to repeatedly tell the group that I'm wrong and lying when for the most part what I'm saying is right. This benefits no one, is harmful and is a waste of my time. I avoid commenting on your posts unless clarification is absolutely necessary or non-sense. Why do you continually have the need to say I'm wrong when I'm not wrong? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
