2 C> @brief Specify a value to be included in Section 0 or Section 1 when
3 C> writing BUFR messages.

5 C> This subroutine is used to specify a value to be written into a
6 C> specified location within Section 0 or Section 1 of all BUFR messages
7 C> output by future calls to other
8 C> [message-writing subroutines](@ref hierarchy) and
9 C> [subset-writing subroutines](@ref hierarchy).
10 C>
11 C> <p>This subroutine is similar to subroutine pkbs1(), except that
12 C> pkbs1() operates on a single BUFR message passed in via a memory
13 C> array. Alternatively, whenever this subroutine is called, the
14 C> specified IVAL will be written into all BUFR messages output by all
15 C> future calls to other [message-writing subroutines](@ref hierarchy)
16 C> and [subset-writing subroutines](@ref hierarchy),
17 C> for all Fortran logical units that are open for
18 C> output within the application program, unless a subsequent call is
19 C> made to this subroutine with the same value of S01MNEM in order to
20 C> reset the corresponding IVAL again. Otherwise, if this subroutine
21 C> is never called for a particular value of S01MNEM, then a default
22 C> value is used for the corresponding IVAL, as set within subroutine
23 C> msgini(), cmsgini() or dxmini().

30 C> be stored within Section 0 or Section 1 of
31 C> all future output BUFR messages
32 C> - 'BEN' = BUFR edition number
33 C> - 'BMT' = BUFR master table
34 C> - 'OGCE' = Originating center
35 C> - 'GSES' = Originating subcenter
36 C> - 'USN' = Update sequence number
37 C> - 'MTYP' = Data category
38 C> - 'MSBTI' = Data subcategory (international)
39 C> - 'MSBT' = Data subcategory (local)
40 C> - 'MTV' = Version number of master table
41 C> - 'MTVL' = Version number of local tables
42 C> - 'YCEN' = Year of century (1-100)
43 C> - 'CENT' = Century (e.g., 20 for years 1901-2000,
44 C> 21 for years 2001-2100)
45 C> - 'YEAR' = Year (4-digit)
46 C> - 'MNTH' = Month
47 C> - 'DAYS' = Day
48 C> - 'HOUR' = Hour
49 C> - 'MINU' = Minute
50 C> - 'SECO' = Second
51 C>
52 C> @remarks
53 C> - A separate call to this subroutine must be made for each value of
54 C> S01MNEM that is to be set within Section 0 or Section 1 of
55 C> all future output BUFR messages.
56 C> - A call to this subroutine with S01MNEM = 'BEN' and IVAL = 4 will
57 C> force all future output BUFR messages to be encoded using BUFR
58 C> edition 4; otherwise, messages will be encoded using BUFR edition 3
59 C> by default.
60 C> - Values corresponding to S01MNEM = 'YCEN' or 'CENT' can only be stored
61 C> within BUFR messages encoded using BUFR edition 3.
62 C> - Values corresponding to S01MNEM = 'YEAR', 'SECO' or 'MSBTI' can only
63 C> be stored within BUFR messages encoded using BUFR edition 4.
