They're practically the same thing, if you write your code for one of the chips it will work for the other too.

16F877A is just slightly better, the differences are almost negligeble.

If I were you I wouldn't worry much about it ..
After all, you are not migrating from 877 to 877A and the differences are so minor that are probably not worth paying attention ..
Here is document on differences between these two:
