The standard input and output devices (STDIN and STDOUT) may be redirected
on the DOS command line when the program is started by entering special command
sequences after the program name.

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.

*  The source or destination may also be one of the known system devices
   rather than a file (for example >PRN sends the output to the first printer).
