Editing ActionScript (section)

===ActionScript 2.0===
The following code, which works in any compliant player, creates a text field at depth 0, at position (0, 0) on the screen (measured in [[pixel]]s), that is 100 pixels wide and high. Then the <code>text</code> parameter is set to the "{{Mono|Hello, world}}" [[String (computer science)|string]], and it is automatically displayed in the player:
<syntaxhighlight lang="actionscript">
createTextField("greet", 0, 0, 0, 100, 100);
greet.text = "Hello, world";
</syntaxhighlight>
When writing external ActionScript 2.0 class files the above example could be written in a file named {{Mono|Greeter.as}} as following.
<syntaxhighlight lang="actionscript">
class com.example.Greeter extends MovieClip
{
    public function Greeter()
    {
        var txtHello: TextField = this.createTextField("txtHello", 0, 0, 0, 100, 100);
        txtHello.text = "Hello, world";
    }
}
</syntaxhighlight>
