Peter, I'd agree with your directive if you have extent reduction disabled. Otherwise, I'll stick to my recommendation.
I don't think my "more appropriate" is an absolute in the same way as "not appropriate for PDSs in any form." What is your concern with secondary extents on a PDS?

Interesting differentiation. I do not contradict per se, but attributes should be different for DSORG=PS versus DSORG=PO, and DSORGP=PO-E. >I agree COND IMMED or CONDITIONAL is more appropriate for PDS. No, space release is not appropriate for PDSs in any form. PDSs are still limited to 16 extents (if memory serves me right), and each new member as well as each update of existing members will write at the end of the data set's allocated space. After space was releases, each write will add another secondary extent. -- Peter Hunkeler ---------------------------------------------------------------------- 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
