    ... and then, later in your code, you mistakenly write:

        BSF PORTA,Relay    ;Turn on the relay
        or
        PORTA.Relay = 1;   // Turn on the relay.

    You can eliminate this common source of errors by including the
    port name in your #define:

        #define Relay PORTB,0
        or
        #define Relay PORTB.0

    then:

        BSF Relay          ;Turn on the relay in assembly.
        or
        Relay = 1;         // Turn on the relay in C.
