changing code from 16F to 18F microprocessor

[Ioannis]

Agreed 100%.
Started out a project a long time ago on a 16F877A. Ran out of memory, plugged in an 18F452, changed a couple of define's, a few register settings, ran great. Ran out of memory again, plugged in an 18F4620, changed a few more register settings...Same program, ran like a champ (then ran out of code space again, built up an 80pin TQFP-> 40 pin DIP adapter for an 18F8722, plugged it in, changed 1 or 2 register settings, doubled the code space, ran great again).

... then run out of memory again and plugged a ... x86 core 2 with 2gb of memory!

I could run the 18F8722 in external mode and 2GB of flash....and skip the Core2 altogether

But that's what I get when I kept adding crap on top of crap on top of crap
I went thru the code awhile back and tried a fair amount of optimizing. Turns out I could've stuck with the '452 if I'd have just been a bit more diligent in the code writing in the first place.

I think thats called spaggeti programming! You are lazy to optimize it once then it grows linearly, or better exponentially, full of crap! I 've been there too!
