When I was a lad, the JCL was written by programmers. I certainly had to write the JCL for my programs to run; sometimes I even had to punch the cards myself. The use of dynamic STEPLIB is something of a corner case in program execution. I'm not suggesting that an ALLOC command, SVC 99 or IKJDAIR should allow STEPLIB/JOBLIB as a target. It should be managed by a well controlled facility that is custom built for this and with associated security rules. As part of this, if JSCBAUTH is already set, the dynamic STEPLIB should also be checked for presence in the current APF list.-- Regards, Dave [RLU #314465] *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* david.w.n...@googlemail.com (David W Noon) *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
