Expand Volume ID. Takes a four character volume ID (e.g. ABCD) and expands it
to 50 volume ID names (e.g. ABCD01, ABCD02 ... ABCD50). Useful for save/restore
operations to assist the operator in mounting the correct volumes in sequence.
The save/restore function will require the tapes to be mounted according to the
volume ID list, but will not require the full list to be mounted. Must execute
thru QCMDEXC.
