Using Flash MX ActionScript with older versions of Flash

ActionScript changed considerably with the release of Flash 5 and has become more robust with the release of Flash MX. To take advantage of the full power of ActionScript, you must create content for Flash Player 6. If you need to create content for an earlier version of the Flash Player, you won't be able to use every ActionScript element.
