Whups!  So sorry.  I usually try out a new set of parameters at
magnification 10 - a large number of patterns fit very comfortably
at that magnification.  I have generally ranged between 0.1 and 10.

Another hint: to freeze the screen for doing a screendump, type
a space into the console window from which HOP was invoked, then
hit the close box on the Hopalong window... it won't be able to close
until you unfreeze the console window, because it wants to print
a diagnostic message.

I'm surprised no one has scoffed at me for using interlace mode
and then making every dot two pixels high.  Go ahead and scoff -
I had my reasons... :-)

Coming soon, if I can figure out how to initialize a temporary 
raster without bombing my 2000 back to kickstart (and that takes
a LOT of work!) -- HodgePodge, the C Version.  (From Aug '88 
Scientific American.)  Of course, if someone who knows what s/he's
doing gets it done first, I'd be glad to give up the fight.  
O gurus, is there a faster way to convert an entire scan line of
a bitmap into an array of pixel values, or vice versa, then just
ReadPixel/WritePixel'ing each one?  (What I mean is: given an
array of integers, I want to plot a line of pixels whose colors
correspond to those integers, and I wanna do it FAST.)
