Tony: Take a look at tools on cbttape.org <http://cbttape.org/>. Myself, I have an old copy of the IBM freebie that came on the IPO and maybe PDO that generates the idcams control cards. A long time ago IBM dropped the programs but thank goodness it was kept by the people who work in the real world. I have always been an advocate of keeping datasets out of the mastercat. A *LONG* time ago we used to protect the master cat by putting a password on it, RACF and IBM’s willingness to standardized things helped out a lot. Back in the early days of MVS, I had one of the joys of answering calls about DSN not found when people didn’t use a standard installation dsn. AT the time we were putting on massive amounts of fixes and new resvolumes were going at 1 every two months. It finally hurt people enough that they learned the hard way. When we got semi stable we put a password on updates to the master cat. That stopped that dead in the tracks. We got nasty feedback from the users and we just pointed at the standards manual. I wish we could have had RACF at the time, but management wanted a stable MVS before going after dsn standards.
