small changes code doesnt work...

Hello All,

I am having a few problems using a few assembler directives from today morning.

I had a lcd routine program.Its working fine and I have been using this for past 1 year.

Now to make the code more modular,I have made a few changes using the assembler directives.This code doesnt work,and I am unable to figure it out why.A little help is needed.

The following are the two files.The first one is the one which is working fine...

;SUBROUTINE TO DISPLAY DATA ON A 2 LINE LCD IN 4 BIT MODE
;PRECAUTION, THE LCD_INIT SUBROUTINE SHOULD BE CALLED ONLY ONCE
;THIS IS A WORKING CODE.
