Can someone please tell me the difference in these three code chunks?

1. is it casting a string, or incorrect syntax?

2. this works,

3. if #2 works as a plain “” string, then what cases would prompt the string to need _**String(“whatever”)**_ ?

if menu\_item\_txt is a textField at \_level0:

1. 

```auto

for (var i = 0; i < 7; i++) {
        var myText:Object = this[***String(menu_item_txt)*** + i];
        //trace(myText);
        myText.autoSize = true;
        myText.embedFonts = true;
        myText.antiAliasType = "advanced";
        myText.gridFitType = "subpixel";
        myText.thickness = 0;
        myText.sharpness = 45;
    }

```
