   function Case_Rule_For_Names (Item : String) return String is
   begin
      return Translate (Item (Item'First .. Item'First), Upper_Case_Map) & Translate (Item (Item'First + 1 .. Item'Last), Lower_Case_Map);
   end;
begin
   for I in Fruit loop
      Put (Case_Rule_For_Names (Fruit'Image (I)));
