More to try

1)Turn the Comparators OFF to get PORTA to work as intended

2)

TRISA = %11111111

You set all of PORTA inputs here but make them outputs in your code

3)

TRISB = %11000000 'portb.6 and .7 out puts all others in put

You got the comment backwards (0=output, 1 = Input)

4)Remember RA4 is open drain so it needs a pullup on your real circuit

5)
Oh, and it it were me, I would start with this and make this work with the Simulator

TRISB=1
MAIN:
IF PORTB.0 = 1 then
	PORTB.1=1
ELSE
	PORTB.1=0
ENDIF
GOTO MAIN

Post back after you try some of these

I have made these changes:
1 trisa is now %00000000
2 trisb is now %00111111
3 pir is now pirin this should reduse any confusition.
Would this be correct? I will later change armed from porta.4 to portb.6 to not have to use a pull up resister and reduse current draw to a min.
