Function/Subroutine Documentation

This subroutine performs final checks and updates on a BUFR message before writing it to a specified Fortran logical unit.

These final checks and updates include:

Standardizing the BUFR message, if requested via a previous call subroutine stdmsg()
Converting the BUFR message from edition 3 to edition 4, if requested via a previous call to subroutine pkvs01()
Storing any customized values into Section 0 or Section 1 of the BUFR message, if requested via one or more previous calls to subroutine pkvs01()
Storing a tank receipt time into Section 1 of the BUFR message, if requested via a previous call to subroutine strcpt()
For edition 3 BUFR messages, ensuring each section of the message contains an even number of bytes
Storing '7777' into the last four bytes of the BUFR message, and storing the final message length in Section 0
Appending zeroed-out bytes after the end of the BUFR message, up to the next machine word boundary
Encapsulating the BUFR message with IEEE Fortran control words, if requested via a previous call to subroutine setblock()
Storing a copy of the final message into internal arrays for possible later retrival via subroutine writsa()

Parameters

[in]	LUNIT	– integer: Fortran logical unit number for BUFR file
[in]	MESG	– integer(*): BUFR message
[in]	MGBYT	– integer: Size (in bytes) of BUFR message

Program history log:

Date	Programmer	Comments
1994-01-06	J. Woollen	Original author
1997-07-29	J. Woollen	Modified to update the current BUFR version written in Section 0 from 2 to 3
1998-07-08	J. Woollen	Replaced call to Cray library routine ABORT with call to new internal routine bort()
1998-11-24	J. Woollen	Modified to zero out the padding bytes written at the end of Section 4
2000-09-19	J. Woollen	Maximum message length increased from 10,000 to 20,000 bytes
2003-11-04	J. Ator	Don't write to LUNIT if opened by openbf() using IO = 'NUL'
2003-11-04	S. Bender	Added remarks and routine interdependencies
2003-11-04	D. Keyser	Unified/portable for WRF; added documentation; outputs more complete diagnostic info when routine terminates abnormally
2005-11-29	J. Ator	Use getlens(), iupbs01(), padmsg(), pkbs1() and nmwrd(); added logic to call pkbs1() and/or cnved4() when necessary
2009-03-23	J. Ator	Use idxmsg() and errwrt(); add call to atrcpt(); allow standardizing even if data is compressed; work on local copy of input message
2012-09-15	J. Woollen	Modified for C/I/O/BUFR interface; call new routine blocks() for file blocking and new C routine cwrbufr() to write BUFR message to disk file
2014-12-10	J. Ator	Use modules instead of COMMON blocks
2019-05-09	J. Ator	Added dimensions for MSGLEN and MSGTXT
