RE:A86: FindPixel in 84 cycles and 19 bytes



the memory from $8000-$BFFF is used for page flipping on the ti-86.that
means you can't use the memory as "scratch" for asm programming.  if you
write to the region without checking to see what's there, you could be
overwriting something important in whatever page is loaded at the time
(possibly another variable, or even the VAT!).

if you need space to use as scratch, use the text mem, the graph screen
backup, or the stats vars (if you don't plan on using the calc for stats). 
if that's not enough scratch for your purposes, create a prog var called
"temp" and use that.
