An action script is written in text format and is organized in blocks
consisting of related sets of statements.
A block consists in an instruction designed to create an object followed by a
set of statements surrounded by braces ({ }). Statement
blocks can be nested and the most enclosing one within a script corresponds to
the document creation.
A document is made up of a hierarchy containing objects, their properties and the features they own. An action script reflects this object hierarchy.
