    I would add ...

    What if you replace the Relays by LEDs + 220 ohms resistors ???

    I do hope relays are equipped with their freewheel diode ... and NOT powered from the Pic 5v supply ...

    PS : as the program runs fine aboard my EasyPic5 with leds as outputs ... we could reasonnably suppose it's a HARDWARE issue ...

    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!

    Default 1 bad $.50 transistor

    Can really mess up a few days...

    Thanks to all for the support. I guess the fact that when written with binary logic the program worked fine - it threw me for a loop and took focus off the hardware. My apologies ...
