Using Flash MX to create content for Flash Player 5

To use Flash MX to create content for Flash Player 5, set the export version to Flash 5 when you publish your movie.

The strict equality operator (`===`) and the `switch` action are new to Flash MX and are supported by Flash Player 5. (Flash Player 5 doesn't natively support these elements, but Flash uses appropriate emulation code.)
