MAGTAPE -- Magnetic Tape Usage Information                  83/08/01


  A  DOMAIN  network  may read and write data residing on 9-track magnetic tapes
  formatted to a density of 1600 bits per  inch.    Tapes  may  be  either  ANSI
  labeled  or  unlabeled,  with  files of ASCII, EBCDIC, or raw characters.  The
  following general restrictions apply:

     o You must perform the tape operations on the node to which  the  tape
       drive is attached.

     o Only one tape drive may be attached to any particular node.

  The following commands are supplied for use with magnetic tapes:

     o WBAK  (WRITE_BACKUP)  writes  one  or more object trees to a magtape
       'backup file'.  Magtapes written with this program may be  used  for
       backup, or to interchange files with other DOMAIN installations.

     o RBAK  (READ_BACKUP)  indexes  or  restores to disk the contents of a
       backup file written with the WBAK command.

     o RWMT (READ_WRITE_MAGTAPE) transfers files between disk and  magtape.
       Use  this  command  to  interchange  files  with  other,  non-DOMAIN
       installations.

     o EDMTDESC (EDIT_MAGTAPE_DESCRIPTOR_FILE) creates and modifies magtape
       descriptor files.

  Help is available for all of these commands.   Type  'HELP'  followed  by  the
  relevant command name for more information.
