Sorry it's taken me so long to reply to this, but once something's on my

and forget about it when I'm home!

In JW (the name of my game), I have a few sections of code in the screen
drawing kernal that do very specialized things to save cycles. If one
check in the screen kernal is only performed after another check has
proven true, I'll have nearly identical loops where, in the second loop,
I replace the first check with the second. Nothing fancy, but more
space means I can get really creative with the screen drawing and not
sacrifice space for the actual boards (which, with each passing week get
more and more complicated (for better or for worse! ;)). Though your
point is well taken. I could have a specialized loop for each scan line
(to take the extreme case) and not worry about "zipping" each board like
I do now.

Hey, even us Mac users need more than 1 meg now-a-days! ;)
