As a matter of fact,
Found label after column 1. (INT_HANDLER).
was exactly what I saw first. The problem for me was that it referenced something like line 1400 and I had not noticed the caps problem. The line number tempted me to start looking in your program to see if I could get any hints of something that I hadn't done right. I hadn't for a minute thought that your program was at fault. I was more concerned that I hadn't passed a correct parameter. I saw that DT_INTS had special handling for the 18F1230 on it's comparator interrupt and started to wonder if it was a situation similar to the 8 pin devices where GPIO aliased to some other name. A few hours were spent in that loop until, in desperation I just stripped the bone and started to make some progress.

It was kind like "where's Waldo" for a while looking between the 2 copies until it started to become clearer.

Again, I'm trying to pry some tricks out of the group to elevate the process for the less experienced. I'm still one of them, but I'm becoming "less" less experienced.
