DO WHILE question

[fbaker]

This seems like it ought to be a simple thing to code but after many hours of trail and error I can't get it to work. For example, I would like to break into a DO WHILE loop by pressing the ESC key. The loop might start: DO WHILE INKEY() <> K_ESC or something similar. INKEY() apparently does not work for gui code and several other attempts using AppEvent() etc. also do not work so I'm stuck.
Thank you.
