The TAPE command                                       28-MAY-81
        --- ---- -------


             The TAPE command displays the current status  of  the  tape
        drive.  It is useful to save you walking in to the computer room
        to verify that the tape is at a desired position.   To  use  the
        TAPE command, simply type

             TAPE       [or just TAP]

             The display produced by this command  informs  you  of  the
        drive status by means of a sense characteristics function.  Note
        that if the tape is engaged in a lengthy function when you issue
        the  TAPE  command,  it  may  take  a while for the output to be
        produced.  The information that can be returned by  TAPE  is  as
        follows:

             1.  Drive is Offline.  This means that  there  is  no  tape
                 mounted  or  that  the  drive is not turned online.  To
                 turn the drive online, press the "ONLINE" button.

             2.  Tape is past EOT.  The  tape  us  positioned  past  the
                 end-of-tape (EOT) marker.

             3.  Writing  is   prohibited.    The   tape   is   software
                 write-locked.

             4.  Tape is physically write-locked.  The tape was  mounted
                 without a write-enable ring.

             5.  Current  density  is  800  BPI  (or  1600  BPI).   Self
                 explanatory.

             6.  Tape is at load point (BOT).  The  tape  is  positioned
                 right at the beginning.

             7.  Tape is at end-of-volume (EOV).  The tape is positioned
                 right at the end.

             8.  Drive is currently rewinding.  Self explanatory.

             9.  Last tape command encountered EOF.  The last  operation
                 on  the  tape  encountered and end-of-file mark (unless
                 the last operation was a backspace).

             10. Writing  with  extended  inter-record  gap  prohibited.
                 Just  what  is  says:  no recovery will be attempted by
                 the driver if a write error  occurs,  such  as  if  the
                 drive encounters a patch of bad tape.
