Upgrading_Support

   The following topics describe the changes necessary to upgrade
   the level of support for ODS-5. Note that you must first ensure
   that the application meets the default support level before you
   can upgrade it to the full support level.

                                  NOTE

      If you are not using the RMS or QIO interfaces to perform
      disk I/O, the Extended File Specifications support level of
      your application depends on whether the interface you are
      using (such as a language run-time library) provides full
      support.
