Usage of Chr? - ReaperX - 11-23-2011
What exactly does a Chr do? Is it like codes for each letter? Like hex and binary?
RE: Usage of Chr? - 1234hotmaster - 11-25-2011
converts a Decimal code to the string character assigned to it

Wrong, it actually converts Decimal values over to it's string value. Nothing to do with Hex values at all.

like
Code:
Chr(AscW("a"))RE: Usage of Chr? - ArkPhaze - 11-25-2011
I already created a powershell script to convert between string, and octal/hex/decimal. Even though this is an AutoIt scripting forum, I already have a sufficient method that works for me

Thanks guys. That helped but what's the point of it? Is it just used as a substitute for the code incase you don't want someone to know what you used?

Mostly yes but also its sometimes used for having semicolon values in strings so like you want the value "hello" in your string which you can do:
Code:
$var = ""hello""Code:
$var = Chr(34) & "hello" & Chr(34)RE: Usage of Chr? - ReaperX - 11-27-2011
Semicolon Values? They Just Use a Semicolon?

In some languages it's a special character and can't be used in the string so you have to sneak it in there using Chr, otherwise they give you an escape character in that language to make the interpreter read it as a normal char. Like in perl with $, which needs to be escapes in a string to display as a normal "$"
