So using your example I should put the option_reg declaration where I have it in your example below if I want the interupt to occur on the falling edge? I will try this tonight thanks alot!

Code:
LED1 VAR PORTB.1

INCLUDE "DT_INTS-14.bas" ' Base Interrupt System
INCLUDE "ReEnterPBP.bas" ' Include if using PBP interrupts

 OPTION_REG.6 = 0 ' INT on Falling Edge 

ASM
INT_LIST macro ; IntSource, Label, Type, ResetFlag?
       INT_Handler INT_INT, _ToggleLED1, PBP, yes
endm

INT_CREATE ; Creates the interrupt processor

INT_ENABLE INT_INT ; enable external (INT) interrupts

ENDASM

Main:
PAUSE 1
GOTO Main

'---[INT - interrupt handler]---------------------------------------------------
ToggleLED1: 
    TOGGLE LED1
@ INT_RETURN
