    Hi, Roger

    Why do you always want to rebuild the world ???

    Just take a scoping of the supply lines on the PIC pins ... and watch the difference ...

    In certain configs no cap doesn't really matter ... in others you can't do anyting with your PIC. Batteries or not batteries.

    ( I MEASURED a half full 4 Sanyo 2100 mAh NiMh AA cells batt @ 0.45 Ohm internal resistance ... 78L05 does much better !!! )

    If you need ONE good reason ... consider RFI generating on supply lines AND RF Generation.

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