AS3 importing from library

[oPUPo]

Hi guys, does anyone know if it's possible to use variables to call objects from your library onto stage like this:

I have an object in my library called Level01 as is it's linkage

var MyMap:String = "Level01";

addEventListener(Event.ENTER_FRAME,LoadMap);
function LoadMap(event:Event) {
    var myLVL:MovieClip = new MyMap();// how do you use the variable here?
    this.addChild(myLVL);
    myLVL.x = 0;
    myLVL.y = 0;
    removeEventListener(Event.ENTER_FRAME,LoadMap);
}

if i call it directly using:

var myLVL:MovieClip = new Level01();

it works fine but i want to use variables to call the correct object.

Any Ideas?
