For datasets allocated by your TSO session, if you issue 'ddlist' command, you can look for datasets that you currently have allocated that are on the volumes in question. Once found, you will have to discern if they are allocated in the actual logon proc, or logon clist or rexx, or dynamically and deal with them accordingly.
For CATALOG, issue console command 'F CATALOG,ALLOCATED(vvvvvvv)' where vvvvvv= volser, to see what catalog(s) are on the volume that will need to be moved. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
