CPTAPE (COPY TAPE) -- Read/write a cartridge or magnetic tape.                        

usage:  CPTAPE  { -r[ead] | -w[rite] | -v[erify] } <pathname> [-nrw] [-lv] [-reten] 
                [-du] [-dev[ice] {ct|mt}]




FORMAT
                                         
  CPTAPE  { -r[ead] | -w[rite] | -v[erify] } <pathname> [-nrw] [-lv] [-reten] 
                [-du] [-dev[ice] {ct|mt}]

  CPTAPE reads, writes, or verifies the contents of a 1/4" cartridge tape or a 
         magnetic tape.


ARGUMENTS

  -r, -w, -v         Selects the mode of operation -- read, write, or verfy.

  pathname           Specify the pathname of a file to be written to the tape or
                     into which the contents of the tape are to be read. (CPTAPE
                     will prompt you if the file already exists.)


OPTIONS

  -nrw               No-rewind. Reading or writing starts at the current tape
                     position.

  -lv                Leave. Do not rewind the tape at the conclusion of the 
                     operation.

  -reten             Retension. Cartridge tape only. The tape is forward spaced 
                     to the end of the tape and rewound before starting the 
                     operation. This should always be specified the first time 
                     a new tape is to be written. If this option is selected, 
                     <pathname> and -r/-w/-v may be omitted; the tape will just 
                     be retensioned.

  -du                The tape contains an Aegis crash dump. Cartridge tape only.
                     This must be specified when the crash dump is read if the Aegis 
                     dump was written by any of the following Apollo machines:
                     DN3xx, DSP80, DSP90, DN5xx.
                     Note:  This option is NOT to be used for the turbo upgrades,
                     ie. DN5xx-T).

  -dev {mt|ct}       Selects the device type. Mt is entered for magnetic tape and 
                     ct is entered for cartridge tape. If a device type is not 
                     entered the default is cartridge tape.
  


EXAMPLES

  $ cptape -r tape_image         Read the entire contents of a cartridge tape.
  $ cptape -w tape_image -reten  Copy that image onto a new cartridge tape.
  $ cptape -r dump.bl19 -du      Read an Aegis crash dump from a DN3xx, DSP80, DSP90,
                                 or DN5xx machine type.
  $ cptape -r dump.bl19          Read an Aegis crash dump from any machine type
                                 other than in the previous example.
  $ cptape -r tape_image -dev mt Read the entire contents of a magnetic tape.
