12F629 Won't SLEEP

[Bruce]

Put a space between @ and SLEEP.

Edit: I guess this bears a little more detail. What happens is by placing @SLEEP in
there it doesn't generate code for SLEEP, so you land on the next valid instruction
which would be your GPIO.1 = 0.

You don't have the @ symbol before your NOP either, so PBP creates a lable instead
of code for the NOP. @ NOP would be the correct way to insert an assembly NOP
instruction.
