Example
Listing 34-7 lets you experiment with a variety of values to see how the
string.substring() method works. If you are using Navigator 4, try changing the
LANGUAGE attribute of the script to JavaScript1.2 and see the different behavior
when you set the parameters to 5 and 3. The parameters switch themselves, essentially
letting the second index value become the beginning of the extracted substring.
