Yeah, and I don't expect to see sysprogs decompiling JES2 modules to
"improve" functionality, but I've seen it.

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.

Subject: Re: It keeps getting uglier
This happened once with my buggy program. 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.
