One thing that I might add here is that if JOBA is really updating the member, as in opening the member for UPDATE, the PDSE sharing capabilities are diminished as opening a member for UPDATE requires the system to have exclusive access to the data set even if extended sharing is enabled. With that being said, the PDSE can still be shared in this scenario within the same system. --- Tabari Alexander ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
