Shucks... I do recall seeing the highly underrated DEF FN function from CoCo
Basic being used to poll the joystick ports in a single and straigthforward
manner, I don't have my books here so I can not really confirm it was
working with two parameters (X & Y joystick positions) or not... I am
interested in seeing someone post an answer on John's question.
