Whether it depends, depends.  I tried it with a non-SMS prefix.
the data set name was catalogued as on the volume, but DSLIST
Info gave me "Data set not found".  Silly.  If programmer omits
VOLSER, allocation looks for it and creates it if not found; if
programmer supplies VOLSER, allocation trusts him that it exists.
So I have yet no way to create a data set conditionally if I
want to control the VOLSER.

I need to try an experiment with a specific unit address and
omitting VOLSER.  Not practical for applications, and a terrible
way to catalog a data set, but I'm curious.

(I Uncatalogued the stump.)
