Hi:

I have been developed an pic 16f877a application , and it's working fine, but i need to increase the program memory, I start to work whith the pic 18f452, so when I exceed the 8k of program code I call a subrutine and it's doesn't return the program to the code programed then the program became unstable.

I need use some special library?, some body can help me with this problem?

thanks in advance
