NEW:      ORDNUMBER() function
------------------------------------------------------------------------------

     ORDNUMBER() is an Order management function that lets you determine the
     position in the current Order List of the specified Order.  ORDNUMBER()
     searches the Order List in the current work area and returns the
     position of the first Order that matches <cOrderName>.  If
     <cOrderBagName> is the name of an Order Bag newly emptied into the
     current Order List, only those orders in the Order List that have been
     emptied from <cOrderBagName> are searched.
