This is a reply to the question concerning dual output using Turbo
Pascal.

One thing that I have done in the past is to keep all of my writeln's
general in format.  For instance:

    writeln (OUTFILE,'text');

and then simply rewrite OUTFILE. This requires that you be able to go
through each write twice, once for the screen, then rewrite OUTFILE,
then out to the printer.  This isn't always convenient, but is sometimes
usefull.

If anyone else has anything to sy concerning this, I would also
appreciate suggestions, since in my CS classes, I often need to do
something like this.
