Shortening actionscript?

Hello there,

I know this is simple, but I always have a hard time shortening script. Can someone help me shorten this?

MenuBar.btn_Menu0.onRollOver = function() {
        MenuBar.Menu0.gotoAndPlay("Over");
        };
    
    MenuBar.btn_Menu0.onRollOut = function() {
        MenuBar.Menu0.gotoAndPlay("Out");
        };
        
    MenuBar.btn_Menu1.onRollOver = function() {
        MenuBar.Menu1.gotoAndPlay("Over");
        };
    
    MenuBar.btn_Menu1.onRollOut = function() {
        MenuBar.Menu1.gotoAndPlay("Out");
        };

    MenuBar.btn_Menu2.onRollOver = function() {
        MenuBar.Menu2.gotoAndPlay("Over");
        };
    
    MenuBar.btn_Menu2.onRollOut = function() {
        MenuBar.Menu2.gotoAndPlay("Out");
        };

    MenuBar.btn_Menu3.onRollOver = function() {
        MenuBar.Menu3.gotoAndPlay("Over");
        };
    
    MenuBar.btn_Menu3.onRollOut = function() {
        MenuBar.Menu3.gotoAndPlay("Out");
        };

    MenuBar.btn_Menu4.onRollOver = function() {
        MenuBar.Menu4.gotoAndPlay("Over");
        };
    
    MenuBar.btn_Menu4.onRollOut = function() {
        MenuBar.Menu4.gotoAndPlay("Out");
        };

    MenuBar.btn_Menu5.onRollOver = function() {
        MenuBar.Menu5.gotoAndPlay("Over");
        };
    
    MenuBar.btn_Menu5.onRollOut = function() {
        MenuBar.Menu5.gotoAndPlay("Out");
        };

I tried this…but to no avail

for (var i = 0; i<6; i++) {
    MenuBar["btn_Menu"+i].onRollOver = function() {
        MenuBar["Menu"+i}.gotoAndPlay("Over");
        };
    
    MenuBar["btn_Menu"+i].onRollOut = function() {
        MenuBar["Menu"+i].gotoAndPlay("Out");
        };
    
    MenuBar["btn_Menu"+i].onRelease = function() {
        var id:Number = Number(this._name.substr(4));
        getURL(url[id]);
        if (id != 0) {
            MenuBar["Menu"+i].enabled = false;
            }
            old.enabled = true;
        if (old != MenuBar.Menu0) {
            old.gotoAndPlay("Out");
            }
            old = this;
            };
}

Thanks,
Lorne
