Luis:

A = B:

        MOVF    ALO,W
        XORWF   BLO,W
        BNZ     NOT_EQUAL
        MOVF    AHI,W
        XORWF   BHI,W
        BNZ     NOT_EQUAL

    EQUAL:

A > B:

        MOVF    ALO,W
        SUBWF   BLO,W
        MOVF    AHI,W
        SKPC
        INCFSZ  AHI,W
        SUBWF   BHI,W
        BNC     A_GREATER

A < B:

        MOVF    BLO,W
        SUBWF   ALO,W
        MOVF    BHI,W
        SKPC
        INCFSZ  BHI,W
        SUBWF   AHI,W
        BC      A_LESS
