C> This subroutine searches for a descriptor within Table A of the
C> internal DX BUFR tables.
C>
C> It is similar to subroutine nemtbax(), except that it calls
C> subroutine bort() if the descriptor is not found in Table A,
C> whereas nemtbax() will return an INOD value of 0 in such cases.

C> @param[in] LUN - integer: Internal I/O stream index associated
C>                  with DX BUFR tables
C> @param[in] NEMO - character*(*): Mnemonic for Table A descriptor
C> @param[out] MTYP - integer: Message type corresponding to NEMO
C> @param[out] MSBT - integer: Message subtype corresponding to NEMO
C> @param[out] INOD - integer: Positional index of NEMO within
C>                    internal Table A
