Format:	/[NO]ALLOCATE

 This qualifier controls the LastPort Tape session behaviour.  The
 default of /ALLOCATE will leave a session to an InfoServer tape service
 active until the MAD device is unbound with the UNBIND verb of LADCP or
 the LADCP DEALLOCATE command is issued.  The use of /NOALLOCATE will
 cause the session to be disconnected when a IO$_UNLOAD or IO$_AVAILABLE
 is issued to the client device.  The use of /ALLOCATE is required to
 perform multi-volume backups.
