1.CDO>  CHANGE GENERIC CDD$EXECUTABLE_IMAGE MY_PROGRAM
      cont>   MCS_PROCESSINGNAME "OUR_PROGRAM".
      cont> END MY_PROGRAM CDD$EXECUTABLE_IMAGE.

      In this example, the CHANGE GENERIC command modifies the
      MCS$PROCESSING_NAME (MCS_processingName property) of the
      generic element MY_PROGRAM. MY_PROGRAM is based on the
      type CDD$EXECUTABLE_IMAGE, which is supplied by Oracle
      CDD/Repository.

    2.CDO>  CHANGE GENERIC BOOK CDO_REFERENCE_MANUAL
      cont>   LIBRARY_NUMBER IS "AA-KL45A-TF".
      cont> END BOOK CDO_REFERENCE_MANUAL.

      In this example, the CHANGE GENERIC command modifies the
      LIBRARY_NUMBER of the CDO_REFERENCE_MANUAL generic element.
      CDO_REFERENCE_MANUAL is based on the user-supplied type BOOK.
