But that was then; this is the 21st Century. A reasonable compromise which allows the user to do something "this strange" would be to allow the operation if the user overrides to DSORG=PS, in either JCL or SVC 99 arguments but forbid it for DSORG=PO. (It's probably a bad idea to permit this override for PDSE.) -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
