Why is this code not working(pwm on a 16f628a)

[Bigandrewgold]

How is the LED connected to the PIC?

EDIT: And what did you use as CONFIG and TRIS settings?

positive end is connected to the pin, negative end is grounded

@ __config _INTRC_OSC_NOCLKOUT & _WDT_ON & _PWRTE_OFF & _MCLRE_OFF & _BODEN_OFF & _LVP_OFF

Define OSC 4


LED4 VAR PortA.1
button VAR PortA.2
CMCON = 7 
VRCON = 0 
PortA=0
PortB = 000100 
T1CON = 000011
TRISA = 000100
TRISB = 000000

and this code works though, which is really confusing me

new:
if button=0 then
    led4=1
    pause 500
    led4=0
endif


goto new
