Pic 16 F877 to 18F452...?

[RodSTAR]

Could you tell both PIC's compilation sizes ?

Maybe you could optimize your code by some labeling repetitive 'procedures' or 'functions'. Almost always something can be done
I've had that problem and modularization has been my solution
16F876 is to 18F252 as
16F877 is to 18F452

Thanks for your reply.
I solve this problem myself.
Problem was 18F452 enstead 18F4520.
When ı copile the prog. ı choose Pic 18F452 than program did not work.
When ı compile as 18F4520 the program work nice.

But ı want to learn another think.
I use " OPTION_REG.7 = 0" at 16F877
but at 18F452 ı getting syntax error for it.
What can ı use enstead for it.
Thaks.
