​OK, I've managed to confuse myself. You want the ENQ for SYSDSN to include
the volser if and only if the DSORG is a PDS, otherwise to omit it? That
is, if DSORG=PO then rname=dsn||volser else rname=dsn?
Again, think 360/30(?) running OS/360 MFT. That's more code in allocation,
which means less core for ​

​the user's program.
