13 C> @param[in] SUBSET - character*(*): Table A mnemonic for type of
14 C> BUFR message to be opened
15 C> (see [DX BUFR Tables](@ref dfbftab) for
16 C> further information about Table A mnemonics)
17 C> @param[in] JDATE - integer: Date-time to be stored within Section 1
18 C> of BUFR message being opened, in format of either
19 C> YYMMDDHH or YYYYMMDDHH
20 C>
21 C> <p>Logical unit LUNIT should have already been opened for output
22 C> operations via a previous call to subroutine openbf().
23 C>
24 C> <p>This subroutine is similar to subroutine openmb(), except that it
25 C> will always open a new message for output, regardless of the values
26 C> of SUBSET and JDATE. Any existing message within the internal
27 C> arrays will be automatically flushed and written to logical unit LUNIT
28 C> via an internal call to subroutine closmg().

31 C> - 1994-01-06 J. Woollen -- Original author
32 C> - 1998-07-08 J. Woollen -- Replaced call to Cray library routine
33 C> "ABORT" with call to new internal BUFRLIB
34 C> routine "BORT"; modified to make Y2K
35 C> compliant
36 C> - 1999-11-18 J. Woollen -- The number of BUFR files which can be
37 C> opened at one time increased from 10 to 32
38 C> (necessary in order to process multiple
39 C> BUFR files under the MPI)
40 C> - 2003-11-04 J. Ator -- Added documentation
41 C> - 2003-11-04 S. Bender -- Added remarks and routine interdependencies
42 C> - 2003-11-04 D. Keyser -- Unified/portable for WRF; added history
43 C> documentation; outputs more complete
44 C> diagnostic info when routine terminates
45 C> abnormally
