        NOTE:  1) This unit has been created and tested on MS/DOS only.
        -----     Porting to the Macintosh will involve some modification,
                  especially for new additions like "BackLn".

               2) Obviously if you do "interesting" things in your programs
                  you can expect some side-effects the authors couldn't
                  possibly forsee. Be careful!
