This simple movie consists of a button that when pressed, prints the number of times it has been pressed to the Output panel. Note that the Output panel is typically only used for tracing and debugging programs. For this reason, the output from this application can only be seen when the application is run from within the Flash authoring environment. We will learn more about how to integrate output into the movie itself in the next tutorial. Step 1. Draw the button Start by opening a new file (Actionscript 3.0) in the Flash authoring environment.
