A program is a set of written instructions to be executed (i.e., carried out) by a computer
or a software application. The written, human-readable text of a program is
called source code, or just code. The person who creates a program is called a programmer,
a coder, or a developer. Every program is written in a particular programming
language, just as every book is written in a particular language (English,
Russian, Japanese, etc.). Programming languages dictate the syntax and grammar
that programmers must use to form the instructions in a given program. This book
provides from-the-ground-up coverage of the syntax, grammar, and usage of one specific
programming language, ActionScript 3.0. Get ready for a good time.
Tools for Writing ActionScript Code
ActionScript code is written in plain text, so an ActionScript program can be created
with nothing more than a simple text editor, such as Notepad on Windows or
TextEdit on Macintosh. However, most ActionScript programmers write ActionScript
code using one (or both) of two commercial tools produced by Adobe Systems Incorporated:
Flex Builder and the Flash authoring tool.
Flex Builder is an integrated development environment, or IDE. An IDE is an application
for writing and managing code, much as a word processor is an application for
creating printed documents. Developers use Flex Builder to create software applications
and multimedia content using either ActionScript or MXML, or both. MXML is
an XML-based language for describing user interfaces.
By contrast, the Flash authoring tool is a hybrid design, animation, and programming
editor. Developers use the Flash authoring tool to create software applications
and multimedia content by combining ActionScript code with manually drawn
graphics, animation, and multimedia assets.
