When any program is running under DOS, the output normally goes to the display
and the input is read from the keyboard.  These standard input and output
devices (STDIN and STDOUT) may be redirected when the program is started by
entering special command sequences after the program name on the command line.

The following command sequences are available:

 >[d:][path]filename - The filename is created and all output that normally
                       would have been sent to the display is sent to the file.
                       WARNING ** If the filename already exists, it is
                       truncated to zero length without warning before output
                       to the file is started!

>>[d:][path]filename - This option functions the same as the command above
                       except that the output to the file is appended to the
                       end of the file (none of its previous contents are
                       lost).  If the filename does not exist, it is created.

 <[d:][path]filename - All standard input is read from the filename specified.
                       WARNING ** ALL program input normally expected from the
                       keyboard must be in the file or else processing will
                       stop when the end of file is reached.  You will then
                       have to return to DOS by pressing Ctrl-Break.
These commands can be very useful as shown in the examples below.

DIR >PRN  - Output from the DIR command is sent to the printer.  This can also
            be accomplished using the Ctrl-PrtSc key (see the help file KEYS
            for details).

TREE >DISKDIR  - Output from the TREE command is sent to the file DISKDIR.

DIR >>CATALOG  - Output from the DIR command is appended to the file CATALOG.
                 This could be useful to create a long file of floppy disk
                 directories, which could then be searched for a particular
                 filename using the DOS FIND command.

SORT <NAMELIST - The name list file could be the input to the DOS SORT command
                 and the sorted output would be sent to the console display.

SORT <SURNAMES >SORTED  - Similar to the example above, the file SURNAMES is
                          provided as the input to the SORT command, and the
                          sorted output is sent to the file SORTED.  The output
                          could just as easily go to the printer by specifying
                          the output as >PRN instead.

         Only the first two characters are required, all others are ignored.
