board. When I downloaded the code I displayed in my previous message
to my OOPic and ran it, every character in the first and third lines
became a dark rectangle, while the second and fourth lines stayed
completely blank. If the problem could be that I need to convert to
ASCII characters, how would I do that? Do you think there's anything
else that could be causing this problem?
Thanks again,
Jason
