 4 Syntax as a command:  copy_mst input_spec output_spec {-control_args}

 7 Function:  copies a Multics System Tape or an MST image stored in a
 8 file into another tape or file.

10 
11 Arguments:
12 input_spec
13    can be either the -input_volume or -input_file control argument, or
14    the reel identification number of a Multics System TAPE from which
15    information is to be copied.  The reel identification number, which
16    is site dependent, can be up to 32 characters long.
17 output_spec
18    can be either the -output_volume or -output_file control argument,
19    or the reel identifier number of the tape onto which the copy is to
20    be made.
21 
22 
23 Control arguments:
24 -input_volume volname, -ivol volname
25    gives the input tape volume name of the MST to be copied.
26 -input_file path, -if path
27    gives the pathname of a file containing the MST image to be copied.
28    This file must have been previously created by generate_mst or
29    copy_mst.
30 -output_volume volname, -ovol volname
31    gives the output tape volume name.
32 -output_file path, -of path
33    gives the pathname of the file into which the MST image is to be
34    copied.
35 
36 
37 -density DEN, -den DEN
38    gives a tape density.  This control argument applies to the previous
39    -input_volume or -output_volume control argument.  DEN may be 800,
40    1600 or 6250.  If given for input tapes, the tapes are mounted on a
41    tape drive capable of reading density DEN.  However, the actual
42    density at which the input tapes are written determines the density
43    used for reading.  If given for output tapes, the tapes are written
44    at density DEN.  The default density is 1600 BPI (bits per inch).

47 Notes:  The message "Tape tape_id1 does not end in a collection mark"
48 is normal for BOS tapes.
