public var startDate:Date;
private var age:int;
}
class Report {

trace(this.startDate); // Access to public variable allowed
trace(this.age); // Access to private variable denied
}
}
}
</source>

//The preceding code is identical to the following code:
var info:Object = new Object( );
info.city = "Toronto";
info.country = "Canada";

}
}

public class Main extends Sprite{
public function Main(){
