use flex Object like java.util.Map

it, easiest

private var myobject:Object = new Object();
myobject["A"] = "Hello";
myobject["B"] = "World";
myobject["C"] = "foobar";

//trace object
trace(myobject["A"]);
trace(myobject["B"]);
trance(myobject["C"]);

//result
// "Hello World foobar"

End. let try..
