MACROMEDIA FLASH 8-USING FLASH Use Manual page 338

Screens are similar to nested movie clips in some ways: Child screens inherit the behavior of
their parents, and you use target paths in ActionScript to send messages from one screen to
another. However, screens do not appear in the library, and you cannot create multiple
instances of a screen. For information on using ActionScript with screens, see
ActionScript with screens (Flash Professional only)" on page
You can add multiple screens to a document, and you can nest screens within other screens, in
as many levels as you want. A screen that is inside another screen is the child of that screen. A
screen that contains another screen is the parent of that screen. If a screen is nested several
layers deep, all the screens above that screen are its ancestors. Screens that are at the same level
are sibling screens. All screens nested in another screen are its descendants. A child screen
contains all the content of its ancestor screens.

About using preloaders with screen-based
documents
If you want to include a preloader (a separate SWF file that loads your primary SWF) with
your screen-based document, one way to do this is to create the preloader as a separate SWF
file (non-screen-based), and load the SWF file for the screen-based document from within the
preloader SWF.
