>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.

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 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
