The SHOW RMS_DATABASE command displays a complete or partial list
    of properties for the RMS database element you specify.

    If you do not specify a version number for an RMS database
    element, CDO displays the highest visible version.

    When you use SHOW RMS_DATABASE or SHOW RMS_DATABASE/FULL to
    display an RMS database element with a NULL_VALUE property, CDO
    displays the null value as a decimal value.
