Excalibur Software PropertyList 3.0
SortItemsSub SortItems()
Description
This method runs a sort on the items in the Properties collection.
If there are no header items, all items will be sorted in ascending order.
Header items will not be sorted; placement is left up to the
discretion of the user. All ranges between header items are sorted
separately; that is, they will remain under the headers where they
were first added.
