My PIC program won't work! Plz Help?!

Hey guys, i wrote a program in assembly for the 80C51 and it worked but now i have to write the same one for the PIC16F84A in assembly language, and it just wont work. Can someone figure out what mistakes i did?
This program controls one 7-segment display to count from 0-9 whilst the other 7-segment display to count from 9-0 at the same time.
Thanks for any help.

Hi, Zammi

first : note here is NOT the best place to ask about Assembler ... much better about PicBasic ... !!!

with my limited skills, ...

I really wonder what you try to do with all those lines groups ... :

Code:

---

MOVLW 0x06
MOVFW PORTB
MOVLW 0xF6
MOVFW PORTB

the aim of my project was to change the 80C51 code program into the PIC assembly language..the original program in assembly language og the 80C51 was this:

dis1 equ P1.0
dis2 equ P1.1
;
org 00h
ljmp main

org 30h;
main: mov r2,#0FCh
mov r3,#0FCh
acall disp
mov r2,#060h
mov r3,#0F6h
acall disp;
mov r2,#0DAh
mov r3,#0FEh
