Since when does z/VSE have GDGs?? ________________________________ From: IBM Mainframe Discussion List <[email protected]> on behalf of Tony Thigpen <[email protected]> Sent: Wednesday, July 11, 2018 1:35 PM To: [email protected] 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.
