12F629 help

[willie]

I have wired up a 12f629 to flash some LEDs on the GP0 and GP1 pins and I also use a 4 Mhz Xtal on GP4 and GP5.

The code I wrote is

loop:
high GPIO.0
pause 750
low GPIO.0
pause 750
high GPIO.1
pause 750
low GPIO.1
pause 750
goto loop
end

But when I power it up it dose nothing.

Can someone help.
