function count()

    // counter is a static variable, defined below.
    // Note that we use it just like a local variable.
    alert("You've called me " + counter + " time(s).");
    // Increment the static variable.  This incremented value
    // will be retained and will be used the next time we are called.

}

// To define the static variable, just set it as a property of the function:
// Note that the only shortcoming of this technique is that static
// variables can only be defined after they are used in the function.
