VMS Help CC, Messages, BADSEVERITY  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 Message        The severity of message id <name> cannot be made less
                severe.  The severity for this message was not
                changed.

 Description    The severities of the compiler's error and fatal
                messages cannot be changed to a severity that is less
                severe.  The compiler's fatal messages cannot be
                changed to any other severity.  The compiler's error
                messages can only be changed to fatals.

 User Action    Remove the pragma or compiler option that tried to
                change the severity.
