			// set the label to appear at the center of the 
			// screen
			myLabel.x = 
				(stage.stageWidth - myLabel.width) /2;
			myLabel.y = 
				(stage.stageHeight - myLabel.height) /2;

			// set the label text to "Hello World!"
			myLabel.text = "Hello World!";

			// add the label to the screen
			addChild(myLabel);
