I figured there was some kind of advantage or something. If it's nothing MAJOR, then I Will go into the data sheets and check it out. I still have a lot to learn about PIC.

Thank you all.
The 'A' really isn't anything major, except for different programming spec's on some chips (might not work with older programmer with older software, 16F877 is not the same as programming a 16F877A), enhanced features that really help a guy out, more features that make more things possible...
So I guess the 'A' really is something relatively major after all...
Buy the 'A's if they're available...
