       1mcatclose 22m?1m-fail 22m| 1m-nofail22m? 4mcathandle0m
              Close  the  message  catalog  specified by 4mcathandle24m.  Normally,
              errors are ignored.  If 1m-fail 22mis specified, any  errors  closing
              the message catalog file are returned.  The option 1m-nofail 22mspec-
              ifies the default behavior of not returning an error.   The  use
              of  1m-fail  22monly makes sense if it was also specified in the call
              to 1mcatopen22m.
