Hiya ive come across this method ‘as’

and I dont get it.

I am following a tut, and i have an array with my objects stored in it (for reference to control these sprites). They are instantiations of my sprite class ‘Ball.as’

```auto
for(i=0;i<3;i++){
var myMCs:Ball = myMCs* as Ball;
}

```

anyone know what it’s meant to be doing?  
In fact - when I remove it - flash doesnt seem to mind its absence.I:-)
