SUBROUTINE WRITLC(LUNIT,CHR,STR) 1,22
C$$$ SUBPROGRAM DOCUMENTATION BLOCK
C
C SUBPROGRAM: WRITLC
C PRGMMR: WOOLLEN ORG: NP20 DATE: 2003-11-04
C
C ABSTRACT: THIS SUBROUTINE PACKS A CHARACTER DATA ELEMENT ASSOCIATED
C WITH A PARTICULAR SUBSET MNEMONIC FROM THE INTERNAL MESSAGE BUFFER
C (ARRAY MBAY IN COMMON BLOCK /BITBUF/). IT IS DESIGNED TO BE USED
C TO STORE CHARACTER ELEMENTS GREATER THAN THE USUAL LENGTH OF EIGHT
C BYTES. NOTE THAT SUBROUTINE WRITSB OR WRITSA MUST HAVE ALREADY
C BEEN CALLED TO STORE ALL OTHER ELEMENTS OF THE SUBSET BEFORE THIS
C SUBROUTINE CAN BE CALLED TO FILL IN ANY LONG CHARACTER STRINGS.
C
C PROGRAM HISTORY LOG:
C 2003-11-04 J. WOOLLEN -- ORIGINAL AUTHOR
C 2003-11-04 D. KEYSER -- UNIFIED/PORTABLE FOR WRF; ADDED
C DOCUMENTATION; OUTPUTS MORE COMPLETE
C DIAGNOSTIC INFO WHEN ROUTINE TERMINATES
C ABNORMALLY
C 2004-08-09 J. ATOR -- MAXIMUM MESSAGE LENGTH INCREASED FROM
C 20,000 TO 50,000 BYTES
C 2005-11-29 J. ATOR -- USE GETLENS
C 2007-01-19 J. ATOR -- REPLACED CALL TO PARSEQ WITH CALL TO PARSTR
C 2009-03-23 J. ATOR -- ADDED '#' OPTION FOR MORE THAN ONE
C OCCURRENCE OF STR
c 2009-08-11 J. WOOLLEN -- ADDED COMMON COMPRS ALONG WITH LOGIC TO
c WRITE LONG STRINGS INTO COMPRESSED SUBSETS
C 2012-12-07 J. ATOR -- ALLOW STR MNEMONIC LENGTH OF UP TO 14 CHARS
C WHEN USED WITH '#' OCCURRENCE CODE
C
C USAGE: CALL WRITLC
(LUNIT, CHR, STR)
C INPUT ARGUMENT LIST:
C LUNIT - INTEGER: FORTRAN LOGICAL UNIT NUMBER FOR BUFR FILE
C CHR - CHARACTER*(*): UNPACKED CHARACTER STRING (I.E.,
C CHARACTER DATA ELEMENT GREATER THAN EIGHT BYTES)
C STR - CHARACTER*(*): MNEMONIC ASSOCIATED WITH STRING IN CHR
