Let me try to remember the number of APARs for IEFBR14...... I
seem to remember, "Eyecatcher" was one, not setting R15 = 0 was
another.....

Could you be thinking of the option to write an EOF when allocating a new PS?

I remember some releases ago of z/OS that the system will
effectively do an OPEN if a DSN is created using IEFBR14. But now
I can't seem to find where that is documented. So far I can't
find it in the z/OS 2.2 or 3.1 JCL User's guide.
I think that if the allocation specified the DCB info (LRECL,
RECFM, and blksize) that this would be put into the VTOC when
IEFBR14 was used to do the allocation.
So in a case like this, would the last ref date be "empty"?
