1 TPCOPY
                       [1mTPCOPY - Tape Copy Program
                       ==========================[0m

    The  TPCOPY  program  is a very  flexible  program  which  copies
    between a mag-tape and a disk file.  The disk file is a specially
    formatted "container file" which contains the entire image of the
    tape.  The main use of TPCOPY is to duplicate tapes or to convert
    a tape from one density to another.

    To use TPCOPY for duplicating  tapes,  you copy the "master" tape
    to a container file on disk,  then for each duplicate tape,  copy
    the container file out to the tape.

    To use TPCOPY for changing  the density of a tape,  read the tape
    into a temporary  container  file,  change the density setting on
    the tape drive  and then write  the container  file  back  out to
    tape.  Then [1mdelete the temporary file[0m.

2 TAPE_TO_DISK

                  [1mTPCOPY - Tape to Disk Command Format
                  ====================================[0m

    To copy a tape into a "container" file on disk, the command is:

        $ TPCOPY file=MSA0:

    where 'file' is the name you want to give to the container  file.
    If you are using TPCOPY  to reformat  a tape to another  density,
    you can name the file  something  like  TEMP.TPC,  so you'll know
    it's a scratch  file if you happen to see it a few days later and
    you forgot to delete  it.   If you making  a "master",  such as a
    CT*OS Demo Tape image,  name the file CTOSDEMO.TPC,  or something
    that will jog your memory as to it's contents.   There is no easy
    way to look  at the contents  of a container  file  and determine
    what is there.

2 DISK_TO_TAPE

                  [1mTPCOPY - Disk to Tape Command Format
                  ====================================[0m

    To recreate a tape from a TPCOPY "container" file, the command
    looks like this:

        $ TPCOPY MSA0:=file

    where 'file' is the name of the container file.

2 CHANGE_DENSITY

                     [1mTPCOPY - Changing Tape Density
                     ==============================[0m

    To use TPCOPY to change the density of a tape, do the following
    steps:

        $ ALLOCATE MSA0:
        $ MOUNT/FOREIGN MSA0:
        $ TPCOPY TEMP.TPC=MSA0:
        $
        < At this point, go in and change the density on the tape >
        $ TPCOPY MSA0:=TEMP.TPC
        [1m$ DELETE TEMP.TPC;*[0m
        $ DISMOUNT MSA0:
        $ DEALLOCATE MSA0:

    That's all there is to it.  Try to figure out what each step
    does.
