SUBROUTINE PKVS01(S01MNEM,IVAL) 2,1
C$$$ SUBPROGRAM DOCUMENTATION BLOCK
C
C SUBPROGRAM: PKVS01
C PRGMMR: ATOR ORG: NP12 DATE: 2005-11-29
C
C ABSTRACT: THIS SUBROUTINE IS USED TO SPECIFY A VALUE TO BE WRITTEN
C INTO A SPECIFIED LOCATION WITHIN SECTION 0 OR SECTION 1 OF ALL BUFR
C MESSAGES THAT WILL BE OUTPUT BY FUTURE CALLS TO ANY OF THE BUFR
C ARCHIVE LIBRARY SUBROUTINES WHICH CREATE SUCH MESSAGES (E.G. WRITCP,
C WRITSB, COPYMG, WRITSA, ETC.). IT WILL WORK ON ANY MESSAGE ENCODED
C USING BUFR EDITION 2, 3 OR 4, AND IT CAN BE CALLED AT ANY TIME,
C INCLUDING BEFORE THE FIRST CALL TO BUFR ARCHIVE LIBRARY SUBROUTINE
C OPENBF IF IT IS DESIRED FOR THE NEW VALUE TO ALSO BE INCLUDED IN ANY
C DX DICTIONARY TABLE MESSAGES THAT WILL BE OUTPUT BY BUFR ARCHIVE
C LIBRARY SUBROUTINE WRITDX. IN ANY CASE, THE LOCATION WITHIN WHICH
C TO STORE THE VALUE IS SPECIFIED VIA THE MNEMONIC S01MNEM, AS
C EXPLAINED IN FURTHER DETAIL BELOW. IF MULTIPLE VALUES ARE DESIRED
C TO BE CHANGED WITHIN SECTION 0 OR SECTION 1 OF FUTURE OUTPUT
C MESSAGES, THEN EACH SUCH VALUE (AND CORRESPONDING LOCATION)
C SHOULD BE SPECIFIED USING A SEPARATE CALL TO THIS SUBROUTINE.
C NOTE THAT EACH CALL TO THIS SUBROUTINE WITH A PARTICULAR LOCATION
C SPECIFICATION WILL OVERRIDE THE EFFECT OF ANY PREVIOUS CALL WITH
C THAT SAME SPECIFICATION (OR, IN THE CASE OF THE FIRST CALL WITH A
C PARTICULAR LOCATION SPECIFICATION, IT WILL OVERRIDE THE DEFAULT
C SECTION 0 OR SECTION 1 VALUE FOR THE CORRESPONDING LOCATION!).

C USAGE: CALL PKVS01

C INPUT ARGUMENT LIST:
C S01MNEM - CHARACTER*(*): MNEMONIC SPECIFYING LOCATION WHERE IVAL
C IS TO BE STORED WITHIN SECTION 0 OR SECTION 1 OF ALL
C FUTURE OUTPUT BUFR MESSAGES:
C 'BEN' = BUFR EDITION NUMBER
C 'BMT' = BUFR MASTER TABLE
C 'OGCE' = ORIGINATING CENTER
C 'GSES' = ORIGINATING SUBCENTER
C (NOTE: THIS VALUE WILL BE STORED ONLY IN
C BUFR EDITION 3 OR 4 MESSAGES!)
C 'USN' = UPDATE SEQUENCE NUMBER
C 'MTYP' = DATA CATEGORY
C 'MSBTI' = DATA SUBCATEGORY (INTERNATIONAL)
C (NOTE: THIS VALUE WILL BE STORED ONLY IN
C BUFR EDITION 4 MESSAGES!)
C 'MSBT' = DATA SUBCATEGORY (LOCAL)
C 'MTV' = VERSION NUMBER OF MASTER TABLE
C 'MTVL' = VERSION NUMBER OF LOCAL TABLES
C 'YCEN' = YEAR OF CENTURY (1-100)
C (NOTE: THIS VALUE WILL BE STORED ONLY IN
C BUFR EDITION 2 AND 3 MESSAGES!)
C 'CENT' = CENTURY (I.E., 20 FOR YEARS 1901-2000,
C 21 FOR YEARS 2001-2100)
C (NOTE: THIS VALUE WILL BE STORED ONLY IN
C BUFR EDITION 2 AND 3 MESSAGES!)
C 'YEAR' = YEAR (4-DIGIT)
C (NOTE: THIS VALUE WILL BE STORED ONLY IN
C BUFR EDITION 4 MESSAGES!)
C 'MNTH' = MONTH
C 'DAYS' = DAY
C 'HOUR' = HOUR
C 'MINU' = MINUTE
C 'SECO' = SECOND
C (NOTE: THIS VALUE WILL BE STORED ONLY IN
C BUFR EDITION 4 MESSAGES!)
C 'INIT' = THIS IS A SPECIAL FLAG TO FORCE THE
C INITIALIZATION OF NS01V = 0 WITHIN
C COMMON /S01CM/; IN THIS CASE IVAL IS
C IGNORED
