PIC12F629 flash led

Shouldn't DEFINE be uppercase?

You have set GPIO.0 as an input with your TRISIO = %00000001 statement.

Try using TRISIO = 0 instead and see how it goes.

Also, I am not sure of your purpose for the OSCCAL statement. IMO, it shouldn't be necessary for such a simple LED flash program.
