Useless (as in totally nonfuntional) for indirectly catalogued datasets.
These are generally resident on the only volumes in the shop you want to
make "read only" - for example to protect the production copies of SMP
targets that get hit during system updates.

Adjusting either for different resvols during build cycles would be a PITA -
and too error prone.
I doubt auditors would approve of such.
Bruces solution offers the best result - *WAY* too complex for such a simple
need IMHO.
The Security Server (nee RACF) people should be held responsible for this
little pool of quicksand.
Last I looked ACF2 had a simple solution to this - same probably applies to
TSS.

As with most things, this has been hashed before - the archives will be
relevant.
