I suspect that the PDSE address space would not have a problem but the data set itself though. Does the IPCS VERBX SMSXDATA show you PDSE latches? You could just casually free one of these (Vary SMS,.. FREELATCH) and see if it causes any problems (especially if you try to edit the same member from a different address space). I seriously don't think you need to be concerned about the PDSE address space recovery. -- John ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
