Global Functions
This section contains a set of built-in functions that are available in any part of a SWF file
where ActionScript is used. These global functions cover a wide variety of common
programming tasks such as working with data types (Boolean(), int(), and so on),
producing debugging information (trace()), and communicating with Flash Player or the
browser (fscommand()).
