Each component has unique parameters that you can set to change its appearance and behavior. A parameter is a property or method that appears in the Property inspector. The most commonly used properties and methods appear as authoring parameters; others must be set using scripting only. After playback has begun, you can get and set parameters on a sprite instance of a Flash component in much the same way that you customize Flash content. For more information, see Using Lingo or JavaScript syntax to set and test Flash variables.
