In my *actual* code, I am storing the result from expandtabs()
I was away from the computer where my sources were, so I just typed in
a quick
example- but overlooked storeing the result from expantabs().

That being said, I still don't understand why the index returned from
find()does not give me the correct offset into the string, where the
label HeXNUM is.
