pic16f877a assembly langauage code errors

[Osama Javed]

I have written a code in assembly language for the Generator autostart and off circuitry. I have tried compiling it in MPLAB but it is giving me so many errors. The code is for PIC16f877a.

Can anyone tell me what to include or what to remove so that my code works fine. I have not included any header file or anything yet.
I am a new user to PIC and MPLAB. Kindly guide me about this.

The code is attached here with this message below:

At least you should include the definitions for the uC you are using.
Example:
list p=16f887a
include <P16f887a.INC>
