Picking up on something Paul G. said in another thread, I realized I have
never known *why* the system issues JOB scope ENQ's on DSN's.

I do realize that it is most probably to avoid an ENQ "deadly embrace"
somewhere along the line, but for the life of me (well, and maybe because
it's Friday) I can't think why a DSN ENQ would be JOB scope instead of STEP
scope.  At least not by default, anyway.

I suppose if you create a dataset in step A and then use it DISP=SHR in step
B (or F or Z, way down the line), if it were not JOB scope ENQueued some
other job could come in-between your create and use steps and delete it on
you, or update it in some clever but unscrupulous way, but I really can't
think of a scenario that means JOB scope ENQ's are required.

TIA for curing my ignorance on this subject.
