Most programming languages delimit the main program section with a keyword such as Main() or main(). JScript .NET (as well as JavaScript) is different. The main code in JScript .NET is not delimited in any way. You just write the code outside; before, after, or in between the class definitions. Here is an example that includes two class definitions followed by the main code section:

  // compile with: jsc inheritance.js

  class Base {
    protected var i : int = 5;
    public function PrintInBase() : void {
      print("i is " +  i);
    }
  }

  class Derived extends Base {
    var d : double = 7.3;
    public function PrintInDerived() : void {
      print("i is " + i + ", d is " + d);
    }
  }

  var b : Base = new Base();
  print("b:");
  b.PrintInBase();
  var d : Derived = new Derived();
  print("d:");
  d.PrintInBase();
  d.PrintInDerived();
