Well, I agree on slight reflection. But you know...
after you have written several hundreds of lines of code
you definitely do not seem to remember all the ins and outs of
all the aspects of programming (tired?). Most likely, if I had
pondered over the issue for some time, I'd have come
to the same conclusion as you have. But anyway,
they say that True = -1 and this is what I have always
had in my mind. It was hard to forsee, after all, that
for bytes it would not work that well.... :) Good to know,
though, that there is a perfectly valid explanation of
what has happened.
