I'm curious. How can you test out "a started task under TESTAUTH" (or TEST)? I
know only how to test programs in my TSO session using these commands.

assembler code, i.e. let your ESTAE retry. Your retry routine saves all the
information your signal handler must know, goes back to AMODE 31, deregisters
your ESTAE and ABENDs with some user abend code. LE's ESTAE will catch up and
your signal handler should finally be driv

Multiple Jobs to Update a Generation Data Group":
This topic provides guidelines that you can use when you submit multiple jobs
that update a particular GDG:
- No two jobs running concurrently can refer to the
the same resource and accidentally replace the generation data set
with the wrong version in the GDG. To prevent two users from allocating the
same absolute generation data set, take one of the following actions:
o Specify DISP=OLD.
o Specify DISP=SHR and open the data
I think the main problem here is dynamic allocation (SVC99) is not allowing the
unauthorized caller to specify it should enqueue uncondtionally. For that
reason BPXWDYN, TSO ALLOCATE, etc return with "data set in use" instead of
offering the option to wait until it becomes available

handling. Might give you some hints that LE error supresses.
