Example 2: Collections do not Need to Be Keyed by Index
Unlike an array, a keyed collection does not have to be keyed by an index. This example is otherwise the same as Example 1 except that the collection of employees is keyed by the #Surname field instead of a number.
When you type in an employee name and click on the Save button, the employee name is saved in a collection.
When you click on the Show button, all employees entered in the collection are displayed in a message box.
The collection is uniquely keyed by #SurName so a duplicate name will update the existing item in the collection.
