This special code represents the File menu's most-recently-used (MRU) list. It may only appear once in the menu system, and it may not be used on a shortcut menu. To eliminate the MRU list from the File menu, either delete this code from MAPINFOW.MNU or re-create the File menu by issuing a Create Menu statement.
