Sorry.

It somehow showed up in the list of recently appended threads. (or something like that). I normally do not look at old stuff.

I am not sure if this has been mentioned elsewhere on this board (I couldn't find it in a Search), but IEFBR14 no longer has to HRECALL a migrated data set before deleting it.

Apparently, the new behaviour is in z/OS not IEFBR14 itself; the system intercepts HRECALL requests resulting from IEFBR14 and, if the DISP is DELETE,DELETE, it performs an HDELETE instead.

Is that an explicit DELETE,DELETE or does it work with (OLD,DELETE)?

That would make IEFBR14 something "special", like a part of the OS rather than a do-nothing program. Kind of hard to describe. Or have they changed IEFBR14 itself to do that? Interesting.

Sorry, I meant (MOD,DELETE,DELETE). (OLD,DELETE,DELETE) should probably work too. I tend to use the former as it works even if the DSN does not exist.

I understand that they didn't change IEFBR14. It is now treated by the OS as a "special" program. This caused some controversy on IBM-MAIN because it introduces an inconsistency. On the other hand, it is a very useful inconsistency.

The enhancement in z/OS 1.11 is that Batch Allocation/Unallocation processing is checking to see if the program name is exactly 'IEFBR14', and if so, for migrated data sets whose DISP is DELETE, it simply HDELETEs them without HRECALLing them. DISP=(*,DELETE) is applicable.

I ran with PARM='CSIUTIL SCAN MIGR' to get a listing of datasets that would have been deleted and got no output.
