Another idea for duplicating output would be to write a text file device driver
(in Turbo Pascal v 4 or 5).  It would be an output only driver that just wrote
everything sent to it out twice.  If you wanted duplicated output, you'd use
AssignDup (or something) to link output to this file; if you wanted screen-only,
you'd use AssignCrt; and for file-only, you'd use the regular Assign.  After
that, all writes to output would automatically do what you wanted.
