Perhaps you're right. Maybe I did. Maybe I just couldn't find it.
Here is the code, both old and new, with changes in font and highlight added in
my email. If you could spare a little time, please tell me where, because I am
just not able to get it. Neither did the compiler. I'll be happy to widen my
"experience level" :-)The program wasn't even returning to the calling function
after this first (highlighted) line, nor was it going to the last line, nor any
line after the (first highlighted) line. Anything before this (first
highlighted) line was reached, ran perfectly, whether lcd calls, or port bit
toggles, whatever.
Thank you for your support and time.

This sounds a lot as if you did add an extra semicolon somewhere it
wasn't meant to go when you typed the program the first time.
