    On all 8-pin pics(that i know of) it's called TRISIO. The port itself is called GPIO.

    So, to set up an I/O in my variable list, what should it look like?

    SERIAL VAR PORTIO.3 ?

    No,
    SERIAL VAR GPIO.3
    You can read all of this in the datasheet of your processor you want to use.
