Stop timeline

programming flash
1

Hi.
I have 2 keyframes on time line.
And i have separated code like:
package {
import flash.display.Sprite;

public class Example extends Sprite {
    public function Example() {
        myTest();
    }
    private function myTest():void {
        trace("hello");
    }
}

}

How i can stop my time line on keyframe 1.
