Did your friend say why you should move to the 196?

Actually I'm not going to bother. Here's why: moving to the Intel part would
require you learning a completely new toolchain, from programming language,
to programmer, to architecture, to programming style. As a 16F84A user you
have already invested a significant amount of time in learning how PICs
operate. In short unless the 196 absolutely does something the 877 cannot,
it is doubtful that switching will be very productive.

One last point. Where exactly are you going to go to ask 80C196 questions? ;-)

Unless your friend can explain to you in detail why you need a new hammer,
you are much better off using the hammer you already know. The very fact that
you are here asking why you should consider switching means that he doesn't.

One last caveat: be mindful that the 16F877A (note the A) has a different
programming specification than the 16F877 (without the A). So while your
programmer may work with the latter, the former is another kettle of fish.
