ActionScript 2 Console
Actionscript is a compiled language, which makes experimenting a bit tedious.
This page aims to make things easier:
Type your code in the bottom half of this page
Press the "Compile" button.
See your code running (or see a compiler error. whichever.)
There's an area between the movie and the input field for trace messages to be displayed.
You can start by pressing the Compile button at the bottom left of the page.
