A Function in Flash 8 help file should be changed

At curveTo Function,there is an example how to create a
circle by ActionScript:

quote:

---

this.createEmptyMovieClip(“circle2_mc”, 2);

circle2_mc.lineStyle(0, 0×000000);

drawCircle(circle2_mc, 100, 100, 100);

function drawCircle(mc:MovieClip, x:Number, y:Number,
r:Number):Void {

mc.moveTo(x+r, y);

mc.curveTo(r+x, Math.tan(Math.PI/8)*r+y,
Math.sin(Math.PI/4)*r+x, Math.sin(Math.PI/4)*r+y);

mc.curveTo(Math.tan(Math.PI/8)*r+x, r+y, x, r+y);

mc.curveTo(-Math.tan(Math.PI/8)*r+x, r+y,
-Math.sin(Math.PI/4)*r+x, Math.sin(Math.PI/4)*r+y);

mc.curveTo(-r+x, Math.tan(Math.PI/8)*r+y, -r+x, y);

mc.curveTo(-r+x, -Math.tan(Math.PI/8)*r+y,
-Math.sin(Math.PI/4)*r+x, -Math.sin(Math.PI/4)*r+y);

mc.curveTo(-Math.tan(Math.PI/8)*r+x, -r+y, x, -r+y);

mc.curveTo(Math.tan(Math.PI/8)*r+x, -r+y,
Math.sin(Math.PI/4)*r+x, -Math.sin(Math.PI/4)*r+y);

mc.curveTo(r+x, -Math.tan(Math.PI/8)*r+y, r+x, y);

}
