Your RCF?  Yes.

To the contention that RMODE is something of an indicator of [loaded]
location in virtual storage my response would be that it is a quondam
indicator, but that providing support for the the value RMODE=ANY
emptied it of any such indicative content.

About  JOBLIB and STEPLIB usage EJ's point is of course the conclusive
one.  A single pointer may be nul or point to one of two libraries.
It cannot point to both.

This implicit EXOR scheme is what we have; the question whether it is
a good one is more complicated.  I would not have painted myself into
a corner in this way.   A pair of pointers, even if one of them were
currently always null, would have been a better choice.
