substitute

()method 
public static function substitute(str:String, ... rest):String

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Substitutes "{n}" tokens within the specified string with the respective arguments passed in.

Parameters

str:String — The string to make substitutions in. This string can contain special tokens of the form {n}, where n is a zero based index, that will be replaced with the additional parameters found at that index if specified.
 
... rest — Additional parameters that can be substituted in the str parameter at each {n} location, where n is an integer (zero based) index value into the array of values specified. If the first parameter is an array this array will be used as a parameter list. This allows reuse of this routine in other methods that want to use the ... rest signature. For example
         public function myTracer(str:String, ... rest):void
         { 
             label.text += StringUtil.substitute(str, rest) + "\n";
