The following example demonstrates enabling ROOT buffer objects
    and disabling PAGE buffer objects. The RMU /DUMP /HEADER command
    is used to validate the change.

              $RMU /SET BUFFER_OBJECT /ENABLE=(ROOT) /DISABLE=(PAGE) MF_PERSONNEL
              %RMU-I-MODIFIED, Buffer objects state modified
              %RMU-W-DOFULLBCK, full database backup should be done to ensure futur
              $ RMU/DUMP/HEAD MF_PERSONNEL
                  .
                  .
                  .

                        Root I/O Buffers
