uses zero based arrays meaning that the first record in an array is at the 0 
position.  Basically this just gives 
a value to the first myema array.  
The zero position is the first data record of the close 
array.

size=2>Hello,

<FONT face="Times New Roman" 
size=3> 

<FONT face="Times New Roman" 
size=2>I fully agree. for/while/if-else + array 
access is covered

<FONT face="Times New Roman" 
size=2>on 3 or 4 pages of any C/C++ 
book

<FONT face="Times New Roman" 
size=3> 

<FONT face="Times New Roman" 
size=2>So this is actually less than 1% of entire 
C/C++ book.

<FONT face="Times New Roman"

<FONT face="Times New Roman"

C++ book

    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!).

        <FONT face="Times New Roman" 
        size=2>I think 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:
