Thanks. Easy enough. An off-list communication described this:
MOUNT [devaddr],vol=(sl,volser)
Does "sl" stand for Standard Label" Is BLP likewise supported?

A search of publibz says, "0 documents have matches for: volarg".
A search of "HELP ALLOCATE" finds no mention of RETAIN, PASS, nor
any option that would assist in referbacks. (REFDD is tempting,
but it isn't documented as supplying VOLSER.) I've been obtaining
VOLSER by allocating the one catalogued data set on the tape and
scanning the TIOT.
My original formulation of this program had a static JCL DD statement
for each data set on the tape. I abandoned that because I feared
encountering an implementation limit. At this point, I'm inclined
to ignore that hazard and revert to static DD statements. IBM seems
disinclined to support use of TSO for accessing tapes; even more
so ISPF.
Thanks,
