The OA50565 fix changed the TSO/E environment service to turn on PSCBJCL
when running in an APF authorized jobstep (i.e. when JCSBAUTH is on).
IDCAMS is linked in SYS1.LINKLIB with AC(1), so an EXEC PGM=IDCAMS jobstep
is APF authorized.

> Searching I found OA50565 which describes the same thing happening

> subtask was calling IKJTSOEV and that causes the PSCBJCL flag to be
> turned off so the task cannot submit jobs. The apar

> task that does the allocation seems to work OK so far: I set the
> flag on, allocate the INTRDR, turn it off and nobody seems to
