The 18Fxxx chips are, for the most part, a joy to use. I have converted several large applications from 16Cs to 18Fs and the code is just a lot more straightforward to write. There are a few things I wish they had done in the 18Fs which didn't happen, but for the most part they did just fine. My two cents - YMMV. Roy J.
