Cool Caesar! Regarding DIALOG, I added two demonstrations (after your Line 25) of how to assign YES/NO responses and the SAVE dialog, which is convenient because not only can you use it as a normal save screen, but as it's an alphanumeric keyboard (numbers and letters only), it's also great for math quizzes or spelling bees since the user can't type random nonsense.
