The SHOW ALL command displays a complete or partial list of
    properties for all visible elements in the default directory.

    If you have your default directory set to a directory in the
    compatibility repository, the SHOW ALL command displays DMU
    record definitions of the CDD$RECORD type, but cannot display
    other definitions that may be stored in your DMU repository. Some
    examples of DMU definitions that CDO cannot display include the
    following:

    o  ACMS application, menu, task group, and task definitions

    o  DATATRIEVE domain, plot, table and view definitions, and
       procedures

    o  DBMS schema, subschemas, security schemas, and storage schemas

    o  Oracle Rdb relation, constraint, index, view, and field
       definitions

    o  TDMS form, request, and request library definitions

    When you display definitions from the compatibility repository,
    CDO displays DMU definitions in CDO format.

    You must have read access to an element for CDO to display
    information on that element.

    CDO displays type definitions only if your default directory is
    set to the CDD$PROTOCOLS directory.
