Jon,

There does seem to be some confussion.

The final word can only come from the program.
When you don't know how something works or when
something isn't working like you think it should,
it is time to find out what the program thinks (and
does),

The way to do this is to write a simple, small program
who's only job is to see what the code in question is
doing.  If your DOS has QBasic, then this is a good
language in which to write test programs.  Or if you
can test it with the Stamp basic, then that is more
certain.  When you are playing with logic operators
I would suggest that you display your input and output
in binary,  This will help you see what is going on with

the program.

You show a lot of promise in that you found the code in
your program that wasn't working like yor thought it should
and you did some testing to see what it was doing.  Then you
posted a question with just the troubled code and stated
your question in a clear manner.  Now it may be time to
play with the code in question and find what it does  under
various inputs.  With this knowledge you will be able to
develop your own 'rules'.

As for what makes a TRUE value, when I read the post that
stated that TRUE was 0, I thought I had bade a big bobo.
Then I looked at your post and seen what you said TRUE was
and thought that this had influenced me and caused me to
give the wrong value for TRUE.  The thing is that it is
easy to think one thing and say another or just get things
wrong.  And one should NEVER ignore the possibility that
they are wrong.

So what is a TRUE value?  What does the book say?  Does the
assembler, compiler or interputer work like the book says?
Yes, it is like the guy who said "I wish the person who drew
the cover had wrote the book."  So the assembler, compiler,
interpeter may have a bug.
