DISK                                                      CMS Transient command

Use the DISK command to punch CMS disk files to the virtual spooled card punch
in a special format which allows the punched deck to be restored to disk in the
form of the original disk file.  Also, use the DISK command to restore punched
decks created by the DISK DUMP command to a disk file.  The format of the DISK
command is:
+----------+------------------------------------------------------------------+
| DISK     | DUMP fn ft [fm]                                                  |
|          | LOAD                                                             |
+----------+------------------------------------------------------------------+
where:

DUMP fn ft fm
         punches the specified file (fn ft fm).  The file may have either
         fixed- or variable-length records.  After all data is punched, an
         end-of-file card is created with an N in column 5.  This card contains
         directory information and must remain in the deck.  The original disk
         file is retained.

LOAD     loads a file or files from the spooled card reader and writes them as
         CMS files on your A-disk.  A file may also be loaded to a disk other
         than your A-disk through the use of the prompting facility.  The
         filename and filetype are obtained from the card stream.  If a file
         exists with the same filename and filetype as one of those in the card
         stream, it is replaced.


Usage notes:

1.  To read files with the DISK LOAD command, they must have been created by
    the DISK DUMP command.  To load spooled reader files created in any other
    manner, use the READCARD command.

2.  To load reader files created by DISK DUMP, you must issue the DISK LOAD
    command for each spool file.  For example, if you enter:
       disk dump source1 assemble
       disk dump source2 assemble
    the virtual machine that receives the files must issue the DISK LOAD
    command twice to read the files onto disk.  If you use the CP SPOOL command
    to spool continuous, for example:
       cp spool punch cont
       disk dump source1 assemble
       disk dump source2 assemble
       cp spool punch nocont close
    then you only need to issue the DISK LOAD command once to read both files.
