BS2p variable stuck

Hi

I have narrowed a problem down to stuck variable(s) (true) in a
program.
I had prev. thought it to be an input problem, but now have the input
and outside world isolated except for my output pin.

any label like this,

label VAR Bit is always true even if I write label = 0

program is runing ok, debug shows the problem and my IF label Then is
showing that the label is true.

any ideas? bad stamp?

Bruce

    Bruce:

    No, I'm pretty sure it's not a bad Stamp. I'm quite certain it's a
    programming error. Put this bit of code just after your declarations
    (before ANY code can run) and you should see the bit flipping
    back-and-forth.

    Test:
    DEBUG HOME, BIN1 label
    label = ~label
    PAUSE 500
    GOTO Test

    Try renaming your label variable to label1

    thanks for info,

    I have improved on it by getting my MAINIO and AUXIO statements in
    place and now I have control from a switch but DEBUG still says it is
    always true even when input is gnd and the label is performing
    correctly as false in my IF statements. oh, well I'll post more as
    I fix it. Can't have too much info in the archives ya know

    Bruce,

    Posting your errant code would probably lead to a quicker solution.

    I got it all working ! (BS2p-40) It was just a matter of having the
    MAINIO, AUXIO in the right places and also having the debug's in the
    right places for the program flow.

    Part of the problem was writing too much code and trying to debug it.
    Bad code can really present some weird problems, I always learn the
    hard way.....

    This basic stamp stuff is really cool.
