#       This script is intended to be used on AIX 4.3.3 and 4.3.2 ONLY.
#       This will use the backup utility doing a level 0 dump on any filesystem defined for $filesys and update /etc/dumpdates.
#       Arguments:
#               DEVICE = <backup device> rmt0 = rewinding rmt0.1 = non-rewinding
#               DUMPINFO = <file that will collect info to be emailed out>
#               MARK = <possition on the tape>
