Exactly my point. It is bad enough with normal programs. The Diagnose instruction interface is constantly changing. I prefer not to shoot myself in the foot.
I don't expect to see IBM publish the Diagnose instruction interface specification. I certainly don't expect to see any IT management group permitting its use. John P.

I hosed CSA, the system crashed, and the operator reIPLed and warm started JES2 which immediately reran my job. Boom - one more crash. I knew immediately after the first crash what to do to fix my bug, but I couldn't fix it until the system stopped autocrashing due to the JES2 initialization parameter to restart all jobs that were running upon warm start. I managed to intervene before the third crash. Your scenario has more blameworthy actions than you described: (1) the programmer whose program uses an interface that is not guaranteed to remain constant; (2) the programmer's (probable) lack of properly documenting his program's dangerous nature; (3) management's allowing such a program to be installed in production while the programmer was still employed; (4) management's not doing a thorough job of review and turnover of that programmer's programs when he left employment; and (5) setting a JES2 initialization parameter that guarantees an infinite loop of crashes as well as production speedup when no wayward program crashed the system (which is usually the case). There is plenty of blame to be shared and lawyered against, although I seriously doubt that management would let the lawyers go after management.
