	In this example, a global variable is set to contain the values of all isindex and form fields set by the browser. The name of the global is the name of the form or isindex field and its value is, of course, the form or isindex field value. This example will not work correctly if there are two or more isindex and/or form fields that share the same name. Multiple fields with the same name are common occurrences in HTML forms, especially in <select> lists that generate a fieldname/value pair for each item selected from the list.
