MACROMEDIA FLASH MX 2004 - ACTIONSCRIPT Reference Manual page 23

Key facts about ActionScript 2.0 include the following points:
•
Scripts that use ActionScript 2.0 to define classes or interfaces must be stored as external script
files, with a single class defined in each script; that is, classes and interfaces cannot be defined
in the Actions panel.
•
You can import individual class files implicitly (by storing them in a location specified by
global or document-specific search paths and then using them in a script) or explicitly (by
using the command); you can import packages (collections of class files in a directory)
import
by using wildcards.
•
Applications developed with ActionScript 2.0 are supported by Flash Player 6 and later.
