    Roman:

    If you don't need it to be fast (and if you can put the code in
    the lower half of a page), you can do this:

        MOVF    COUNT,W
        ADDWF   PC
        XORLW   A ^ (B ^ 1)      ;When COUNT = 0, W = A
        XORLW   B ^ 1 ^ (C ^ 2)  ;When COUNT = 1, W = B
        XORLW   C ^ 2 ^ (D ^ 3)  ;When COUNT = 2, W = C
        XORLW   D ^ 3            ;When COUNT = 3, W = D
