Because, as Plik said, you pass a character as parameter to the function charCodeAtTest( n ) in this code:

code:

---

function OnEvent_ChatWndSendMessage(ChatWnd,Message){
    return '' + charCodeAtTest(Message.charAt(0));
}

---

because charAt(0) will return the first character in the string Message.

So the parameter n in your function charCodeAtTest( n ) is a character, not a number...

And a character minus a number (thus your n-1) results in error code NaN...

And charCodeAt() expects a number (character position, starting from 0 for the first character), not NaN. Hence why it always return the same number, because your n-1 is always NaN.

for example, ' ' = 32, 'a' = 97, 'b' = 98, 'A' = 65, '1' = 49.

string.charCodeAt(character position)

eg:
"ab1def".charCodeAt(0) equals 97
"ab1def".charCodeAt(1) equals 98
"ab1def".charCodeAt(2) equals 49

To check for certain bits in a number use the bitwise operators.
eg:
3 & 1   will equal 1
3 & 2   will equal 2
1 | 2    will equal 3

PS: in the very first reply in this thread, Felu, gave you a link to the JScript documentation. And later on people gave links to that same online documentation. Plenty small examples are given in those docs.
