for (var i:Number = 1; i <= btnNum; i++) {
        ["L" + i + "_mc"].buttonMode = true;
        ["L" + i + "_mc"].addEventListener(MouseEvent.MOUSE_OVER, onOver, false, 0, true);
        ["L" + i + "_mc"].addEventListener(MouseEvent.MOUSE_OUT, onOut, false, 0, true);
}
 
function onOver(e:MouseEvent):void {
        e.target.gotoAndPlay("over");
}
 
function onOut(e:MouseEvent):void {
