Convert to actionscript 3.0

I've got into trouble this code from actionscript 2.0 in a .fla file.

stop();

var tf:TextFormat = new TextFormat();

tf.font="Arial Black";

tf.bold = true;

tf.size = 30;

//tf.color = 0x55FF55;

rotateIn = function() {

      if(this.frameCount++ > this.delay) {

          this.onEnterFrame = function() {

              this.frameCount += 2;

              var n:Number = 30 - (this.frameCount - this.delay);

              this.filters = [new BlurFilter(n, n, 1)];

              this._visible = true;

              this._alpha = 100 - (n * 3);

              if(n < 1) {

                  this._alpha = 100;

                  this.onEnterFrame = undefined;

              }

          }

      }

  }

var frameCounter:Number = 0;

this.onEnterFrame = function() {

    if(frameCounter++ % 70 == 0){

//if(frameCounter++ >= 70 == 0)

        m.removeMovieClip();

        m = TextScript.createEffect(this, "Text Text Text", 50, 10, tf, 2, rotateIn);

        //delete this.onEnterFrame;

    }

}

With bold style I want help with
How do I get with class .as file in an actionscript 2.0 .fla file to an actionscript 3.0 with .fla file to be linked together.
