I've done extensive modifications to FIRST-ED.PAS, the "simple editor"
in the Turbo Pascal Editor Toolbox.  The code is ** VERY ** dependent on
the IBM PC's memory-mapped video, so I think it would be ** EXTREMELY **
difficult to modify it to do character I/O on any other basis.  This is
just my opinion, however.
