would like, but since TJ seems to follow C++ syntax, I can recommend a C++
book that I found to be very good (pretty big though - over 1000 pages).
It is very thorough and easy to understand - definitely geared for
beginners in my opinion. It is "C++ Primer Plus" by Stephen Prata. I think
you could probably just read up on the items you are interested in if you
aren't interested in learning the whole language. Be careful because it
seems that there are a couple of other C++ books that call themselves
"primers", but are definitely NOT for beginners. Especially stay away
from Stanley Lippman's book, at least until you have some experience (take
it from me....please!).

Ken,

<FONT

the concept of loops and if-then-else is the same in all languages. I
imagine you could read up on it at many websites (e.g.
- MSDN scripting site). Once you grasp the concept, it is just a
matter of using AFL syntax. You would probably use it mostly for
iterating your arrays if you wanted to do that. Here is a simple
pseudo-code - try coding it in AFL:
<FONT

<FONT
