AS2 - Actionscript 2 help needed

Hi,

I’m fairly new to Flash and very new to Actionscript, and am working on an example file, in order to increase my knowledge of the subject. There is a piece of Actionscript that I have no idea what it does - would anybody be so kind enough to have a look and see if you can shed some light on the matter…?!

The AS is as follows:

stop();
var interval:Number = setInterval(function () { play();clearInterval(interval);
}, 10000);

Thanks!
