Description:
Q. How do you do I/O redirection?
   How can I write to standard output?
   In version 3.0, I used $P128,G128.  What do I do in Version
   4.0+?
A. If you want to do DOS I/O redirection when running an .EXE
   file generated by Turbo Pascal 4.0+, DO NOT use the Crt unit.
   If you do, make sure you assign a text file variable to the
   standard DOS output device.  For example:

     Assign(Output,''); { assign a text file variable }
                        { to a null file name         }
     Rewrite(Output);   { do a rewrite here           }

   Any Write statement that does not specify a file variable will
   be redirected to the DOS standard output file. You can also
   use Write(Output,...).
