>From the MVS JCL Reference for z/OS 1.13: "Two installation exits, IEFUSI and IEALIMIT, can also affect the size of the user address space assigned to the job step."
Are one or both of these exits in use at your site? I think you can code 0M, but the exit will change that value and you may not see that it was changed.

I thought REGION=0M (or 0K) allowed you to allocate storage up to "whatever is available" (or something like that). ________________________________ From: IBM Mainframe Discussion List <[email protected]> on behalf of Jerry Whitteridge <[email protected]> Sent: Wednesday, January 4, 2017 11:39 AM To: [email protected] Subject: Re: EXTERNAL: Re: SHOWMVS ASMA972U Error Also consider that REGION=0M gives you all storage below the line and 32M above the line. You may want to specify a larger region size and see if that helps. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
