   Comment by the author:
   "After a flood of questions regarding dcl and lisp in the ADG over a period
    of weeks I was inspired to write this dialog box and lisp demo.
    I am NOT a dcl or lisp expert! And I am sure there is more than one way
    to code for the examples included herewith. So with that said I sincerely
    hope that this demo will be of use to someone. It has at least been a good
    learning exercise for me writing it. Also if anyone can be bothered making
    recommendations for correction of errors or simplifications or improvements
    they will be very welcome. Regards, Phill. PS Thanks to Gary for his input."
