        ES_WHOCARES         The condition does not represent a failure; the
                            error is informational.
        ES_WARNING          The condition does not prevent further
                            operations, but may result in a more serious
                            error later.
        ES_ERROR            The condition prevents further operations without
                            corrective action of some kind.
        ES_CATASTROPHIC     The condition requires immediate termination of
                            the application.
        ---------------------------------------------------------------------

        Note that the CA-Clipper runtime support code only generates errors
        with severities of ES_WARNING or ES_ERROR.
