Classes - Quick Question

programming flash

Hey
If I have one Main class that initiates a second class like this:

Main.as
package {
 public class Main extends Sprite {
  function Main() {
   var a = new SecondClass
  }
  public function coolStuff() {
   trace("A");
  }
 }
}

SecondClass.as
package {
 public class SecondClass extends Sprite {
  function SecondClass() {
   //do the coolStuff function in the Main class
  }
 }
}

How do I get my SecondClass to call the coolStuff function in the Main class? I tried doing somthing like “Main.coolStuff()” or “parent.coolStuff()” but it does not inherit and I can not be bothered with inheritance because I do not want to script my stuff like that. For example, I want a textFormat class to be defined on the Main class but used in all classes in my code, how do I do this? Im sorry to ask such a noob question but Im new to OOP and scripting ideas like this.

Thanks for your help,
Dan
