I recommend using Multi_Key instead of your method of detecting multiple
keypresses. Multi_Key is a routine that masks out ALL but the key you
request. Its syntax is so easy, its not likely to ever forget what key you
want. It will even detect the [ON] key. Since we humans are likely to
make fatal mistakes when programming, I made this routine to avoid that
problem. It is flawless (minus the ghost key cominations which is a
hardware problem and not my fault) which makes it the BEST multiple key
detection routine available. This is the first and last routine you will
most likely ever use.

You can only write 8 bits to the display port at a time...not 16. It is
about 10 times faster to write entire bytes and I don't recommend using
Point_On and Point_Off for any decent game.
