cc65.org hasn't been resolving but maybe 10% of the time from
Charter.net - southern Oregon.
I looked at coding tips, hence the use of unsigned ints :) There maybe
one or two other places I could omptimize in the tight loop. I might
try inline assembly, as soon as I learn how to deref the variables :)
will check internal.txt - sounds great.
Still don't know why \n won't work in cprintf, but the inline assembly
for cr(int) works well in the interim.

doc/coding.html gives hints how to write code that is better suited for
cc65.

See doc/internal.txt.
