Gil, I have a preference to use JCL with dd’s in the step(proc) for maintenance. I have been burned by a fellow sysprog as he managed to put the maintenance in the wrong zone. After the IPL I started to get the phone calls saying that X is still broken. The time it takes is a PITA. I then have to track down what went where. I also get a black mark from the programmers and my boss for screwing it up. The black mark from the programmers is aggravating as then they stop trusting me and I have to earn their trust back. The boss is not so forgiving even when a 3rd person is involved. His answer is your fault as you didn’t verify what the person did. Personally I don’t have the time in the day/evening to check out what fellow sysprogs did. About 20 years ago I was putting in 100 hour work weeks and it burned me out. Once I figure out what happened, that means paper work and another scheduled IPL. I can *TRUST* JCL and not worry about the DDEF’s which are for all intents purposes is invisible.
