Here is my servo code?

i am not sure how good it all is ? as i am new to mplab and assembly language!

but i think i may have gone wrong with the servo updates somewhere? ??? :)

each servo is on porta.0 and port a.1 of my 16f84? but i have only written some code for one servo? how do i implement two and get the code to work for me? eg. backwards,forwards?

Below is the code!

Thankyou all in advance
