Trying to create a movie clip that Bounces off four sides of the stage

Question

using the syntax below I have created a movie clip called 'BALL' that bounces off from the left "x"  and moves to the right side of the stage 'x.520' and bounces back to the start "x".
HOW DO I CREATE A MOVIE CLIP THAT BOUNCES FOUR SIDES OF THE STAGE AND STOPS ON THE FOURTH BOUNCE??
var ballTween:Tween = new Tween(ball, "x", Bounce.easeInOut, ball.x,520, 5, true);
ballTween.addEventListener(TweenEvent.MOTION_FINISH,tweenFinishedF);
function tweenFinishedF(e:TweenEvent):void{
new Tween(ball,"x",Bounce.easeOut,ball.x,0,5,true);

Here is a simplest way to do that. This code doesn't use your ball but draws it dynamically. If you want to use your ball instance - replace relevant lines.
import flash.display.Shape;
import flash.display.Sprite;
import flash.events.Event;
import flash.geom.Rectangle;
var ball:Shape;
// speed, naturally
var speed:Number = 7;
// velocity along x
var vx:Number = speed;
// vlocity along y
var vy:Number = speed;
// area within which ball may move
var moveArea:Rectangle;
// radius of ball circle shape
var ballRadius:Number = 20;
init();
function init():void
    moveArea = new Rectangle(ballRadius, ballRadius, stage.stageWidth - ballRadius, stage.stageHeight - ballRadius);
    drawBall();
    addEventListener(Event.ENTER_FRAME, moveBall);
function moveBall(e:Event):void
    // change direction if ball moves out of allowed rectangle
    if (ball.x < moveArea.x)
        vx = speed;
    else if (ball.x > moveArea.width)
        vx = -speed;
    if (ball.y < moveArea.y)
        vy = speed;
    else if (ball.y > moveArea.height)
        vy = -speed;
    ball.x += vx;
    ball.y += vy;
function drawBall():void
    ball = new Shape();
    ball.graphics.beginFill(0xFF0000);
    ball.graphics.drawCircle(0, 0, ballRadius);
    ball.x = moveArea.x + Math.random() * moveArea.width;
    ball.y = moveArea.y + Math.random() * moveArea.height;
    addChild(ball);
