Since when does z/VSE have GDGs?? ________________________________ From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> on behalf of Tony Thigpen <t...@vse2pdf.com> Sent: Wednesday, July 11, 2018 1:35 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: REXX as JCL replacement Restarts with GDGs is one thing z/VSE is much better at. Once a GDG is created in a step, it becomes the current GDG for all following steps. So, following steps don't need to reference +1, then require a change during a restart. It part of the difference that z/OS reads the whole job in then allocates everything where as z/VSE only reads the following JCL after the previous step has completed.

Mainly deleting datasets, but also changing GDG relative generation numbers if the restart is after the step which created the new GDG which is used in subsequent steps. {shudder}---------------------------------------------------------------------- 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
