zantos, It's just telling you that you shouldn't use the 'OPTION' instruction since on all modern PIC's, the option register is directly addressable. You're not going to harm anything by using the option instruction, but future PIC's may not support it. So by getting used to not using it now, you'll be covered in the future.
