     I have a routine in TP 3.0 that does that. It goes....

           WHILE KeyPressed DO
                 read(kbd, dummy);

      Where "dummy" is a character and "KeyPressed" is the TP 3.0
function that checks to see if the keyboard buffer holds any characters.

       Even tho I have TP 4.0, I haven't bothered to convert this yet.
I think "KeyPressed" was renamed in TP 4.0 and you use "readkey" instead
of "read(kbd)". Don't have all the details, but that should do the
trick.

      Hope it helps.....
