SUBROUTINE COPYSB(LUNIN,LUNOT,IRET) 2,20
C$$$ SUBPROGRAM DOCUMENTATION BLOCK
C
C SUBPROGRAM: COPYSB
C PRGMMR: WOOLLEN ORG: NP20 DATE: 1994-01-06
C
C ABSTRACT: THIS SUBROUTINE COPIES A PACKED DATA SUBSET, INTACT, FROM
C LOGICAL UNIT LUNIN, OPENED FOR INPUT VIA A PREVIOUS CALL TO BUFR
C ARCHIVE LIBRARY SUBROUTINE OPENBF, TO LOGICAL UNIT LUNOT, OPENED
C FOR OUTPUT VIA A PREVIOUS CALL TO OPENBF. THE BUFR MESSAGE MUST
C HAVE BEEN PREVIOUSLY READ FROM UNIT LUNIT USING BUFR ARCHIVE
C LIBRARY SUBROUTINE READMG OR READERME AND MAY BE EITHER COMPRESSED
C OR UNCOMPRESSED. ALSO, BUFR ARCHIVE LIBRARY SUBROUTINE OPENMG OR
C OPENMB MUST HAVE BEEN PREVIOUSLY CALLED TO OPEN AND INITIALIZE A
C BUFR MESSAGE WITHIN MEMORY FOR UNIT LUNOT. EACH CALL TO COPYSB
C ADVANCES THE POINTER TO THE BEGINNING OF THE NEXT SUBSET IN BOTH
C THE INPUT AND OUTPUT FILES, UNLESS INPUT PARAMETER LUNOT IS .LE.
C ZERO, IN WHICH CASE THE OUTPUT POINTER IS NOT ADVANCED. THE
C COMPRESSION STATUS OF THE OUTPUT SUBSET/BUFR MESSAGE WILL ALWAYS
C MATCH THAT OF THE INPUT SUBSET/BUFR MESSAGE {I.E., IF INPUT MESSAGE
C IS UNCOMPRESSED(COMPRESSED) OUTPUT MESSAGE WILL BE UNCOMPRESSED
C (COMPRESSED)}.

C PROGRAM HISTORY LOG:
C 1994-01-06 J. WOOLLEN -- ORIGINAL AUTHOR
C 1998-07-08 J. WOOLLEN -- REPLACED CALL TO CRAY LIBRARY ROUTINE
C "ABORT" WITH CALL TO NEW INTERNAL BUFRLIB
C ROUTINE "BORT"
C 1999-11-18 J. WOOLLEN -- THE NUMBER OF BUFR FILES WHICH CAN BE
C OPENED AT ONE TIME INCREASED FROM 10 TO 32
C (NECESSARY IN ORDER TO PROCESS MULTIPLE
C BUFR FILES UNDER THE MPI)
C 2000-09-19 J. WOOLLEN -- MAXIMUM MESSAGE LENGTH INCREASED FROM
C 10,000 TO 20,000 BYTES
C 2002-05-14 J. WOOLLEN -- REMOVED OLD CRAY COMPILER DIRECTIVES
C 2003-11-04 S. BENDER -- ADDED REMARKS/BUFRLIB ROUTINE
C INTERDEPENDENCIES
C 2003-11-04 D. KEYSER -- UNIFIED/PORTABLE FOR WRF; ADDED
C DOCUMENTATION (INCLUDING HISTORY); OUTPUTS
C MORE COMPLETE DIAGNOSTIC INFO WHEN ROUTINE
C TERMINATES ABNORMALLY
C 2004-08-09 J. ATOR -- MAXIMUM MESSAGE LENGTH INCREASED FROM
C 20,000 TO 50,000 BYTES
C 2005-09-16 J. WOOLLEN -- NOW WRITES OUT COMPRESSED SUBSET/MESSAGE IF
C INPUT SUBSET/MESSAGE IS COMPRESSED (BEFORE
C COULD ONLY WRITE OUT UNCOMPRESSED SUBSET/
C MESSAGE REGARDLESS OF COMPRESSION STATUS OF
C INPUT SUBSET/MESSAGE)
C 2009-06-26 J. ATOR -- USE IOK2CPY
C
C USAGE: CALL COPYSB
( LUNIN, LUNOT, IRET )
C INPUT ARGUMENT LIST:
C LUNIN - INTEGER: FORTRAN LOGICAL UNIT NUMBER FOR INPUT BUFR
C FILE
C LUNOT - INTEGER: FORTRAN LOGICAL UNIT NUMBER FOR OUTPUT BUFR
C FILE
C
C OUTPUT ARGUMENT LIST:
C IRET - INTEGER: RETURN CODE:
C 0 = normal return
C -1 = there are no more subsets in the input
C BUFR message
C
C REMARKS:
C THIS ROUTINE CALLS: BORT CMPMSG CPYUPD IOK2CPY
C MESGBC READSB STATUS UFBCPY
C UPB WRITSB
C THIS ROUTINE IS CALLED BY: ICOPYSB
C Also called by application programs.
