Scope is the area where the variable is known and can be used in a SWF file, such as on a timeline, globally across an application, or locally within a function. Typically, you can reference scope in more than one way when you write code. Using scope correctly means that you can create portable and reusable ActionScript code, and you don't risk breaking your applications as you build new modules.
It is important to understand the difference between the global and root scopes. The root scope is unique for each loaded SWF file. The global scope applies to all timelines and scopes within SWF files. You use relative addressing rather than references to root timelines, because relative addressing makes your code reusable and portable. For more information on handling scope in your applications, see the following sections:
