Reading incremental encoder interupt

[rakickv]

Hi I have a problem with interrupts code in pbp.I want to count encoder ticks in both directions,I have done the code without interrupt routine and it works fine but it is to slow for greater speeds.So I tryed with INT on port B.0 but it is not working.I am useing PIC 16F877A, compiler 2.5. Here is the code which is not working.Where was I wrong?

I used the interrupt for my low cost mechanical encoder to control my power supply.
You can find the whole code in the attachement.
The interrupt service routin is the following:
'---[INT - interrupt handler]---------------------------------------------------
ToggleLED1:
if EB=0 then INC_DEC=2
IF EB=1 THEN INC_DEC=1
@ INT_RETURN

Thanks to Darrel Taylor work.

Bye
