        <p>ActionScript 2.0 introduces several new programming keywords and concepts, 
          including classes, inheritance, and interfaces. These concepts comprise 
          what is commonly known as object-oriented programming (see <a href="/devnet/flash/actionscript/actionscript05.html"><strong>Object-Oriented 
          Programming</strong></a>).</p>

<p>Classes you create in ActionScript must be stored in separate ActionScript (AS) files; you can't create classes in a Flash (FLA) frame or button script. Some important points about class files:</p>
<ul>
<li>Only one class can be defined per AS class file.</li>
<li>The name of the file that contains the class must match the class name.</li>
<li>ActionScript class files must be located in a folder where the Flash compiler looks for classes.</li>
<li>You can combine several classes in a folder to create a package.</li>
</ul>

<p>If you're new to creating classes and object-oriented programming, try following the steps in <a href="/go/livedocs_flmx2004_as_class_example" target="mm_window"><strong>Using Classes: A Simple Example</strong></a>.
