SCA$_NORMAL           The query expression string has been
                          successfully parsed.

    SCA$_MORETEXT         Warning. The query expression string has
                          been successfully parsed, but the text
                          following the query expression is not a
                          legal part of the query expression. This
                          condition is returned only if the query_
                          expression_length parameter is specified. If
                          the query_expression_length parmeter is not
                          specified, then this routine insists that
                          the whole query_expression_string argument
                          be a legal query expression; in this case
                          all errors are signaled.
