Thanks to you both - between the sample code and emulator I learned
how to make a game for the Apple! Here is your code with a menu and
more sensitive paddle movement (and I made the ball round :-)
There is no sound or scoring yet (how do you print text in graphics
mode?) and for keyboard mode I haven't figured out how to detect if
two keys are being pressed at once.
Thanks again...
