var1=All dynamic and input text fields in a Flash movie are instances of the TextField object. You can give a text field an instance name in the Property inspector and use the methods
and properties of the TextField object to manipulate it with ActionScript. TextField instance names are displayed in the Movie Explorer and in the Insert Target Path dialog box in
the Actions panel. 

The TextField object inherits from the Object object. 

To create a text field dynamically, you can use the MovieClip.createTextField method. 

The TextField object is supported by Flash Player 6 and later versions of the Flash Player.
