        TAPCOPY Program Abstract

        TAPCOPY copies magtape to magtape bit for bit, using dump mode I/O,
using industry mode if both tapes are 9-track.  Blocksize is determined
by reading the tape.  If the block does not fit in core, TAPCOPY
expands the low segment, backspaces the input tape, and tries again.
Tape error messages interpret each status bit as per Monitor Calls
manual.  Copies to double end-of-file mark.  Initial size: 2+1P.
        Tested on TU-20, TU-40, TU-41 only.
        TAPCOP copies MAGtapes.

How to use:

1.      Mount the input tape.

2.      Mount the output tape write-enabled.

3.      R TAPCOP

4.      Answer the following question(s):

        "Input device: "  Respond with the logical or physical device
                name of the input tape. (If you just type a carriage return,
                the name defaults to "A".)

        "Output device: "  Respond with the logical or physical device
                name of the output tape. (If you just type a carriage return,
                the name defaults to "B".)

5.      If either tape drive is 7-track, the program will ask:

        "Odd parity (Y/N)".  Type Y for yes or N for no.

6.      TAPCOP will copy files until it comes to a double end-of-file mark.
        Then it will rewind both tapes.  It will not rewind any tapes before
        copying, in case you want to avoid copying some files from the front
        of the input tape.

7.      If both tapes are 9-track, TAPCOP will copy in industry-compatible
        mode.  If either or both are 7-track, it will copy in DEC-compatible
        mode.

8.      There is no need to SET BLOCKSIZE.  TAPCOP will determine the blocksize
        for itself.
