Thanks to everyone who replied. Since this may form part of a product shipped to customers, I can't make any assumptions whether they have rmm or CA-1 installed. Therefore opening the data set and saving the DCB info is probably the best way. Incidentally, during my tests the tape is definitely mounted; my colleague did with his own fair hand and 'D U,,,nnn,4'shows he succeeded! -- Thanks -Robin This message has been scanned by MailController - portal1.mailcontroller.co.uk ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
