SUBROUTINE UFBCNT(LUNIT,KMSG,KSUB) 5
C$$$ SUBPROGRAM DOCUMENTATION BLOCK
C
C SUBPROGRAM: UFBCNT
C PRGMMR: WOOLLEN ORG: NP20 DATE: 1994-01-06
C
C ABSTRACT: THIS SUBROUTINE RETURNS A COUNT OF THE CURRENT MESSAGE
C NUMBER AND SUBSET NUMBER, WHERE THE MESSAGE NUMBER IS RELATIVE TO
C ALL MESSAGES IN THE BUFR FILE AND THE SUBSET NUMBER IS RELATIVE TO
C ALL SUBSETS IN THE MESSAGE. IF THE MESSAGE/SUBSET ARE BEING READ,
C THE MESSAGE COUNT ADVANCES EACH TIME BUFR ARCHIVE LIBRARY
<A NAME='READMG'><A href='../../html_code/bufr/ufbcnt.f.html#READMG' TARGET='top_target'><IMG SRC="../../gif/bar_red.gif" border=0></A>
C SUBROUTINE READMG (OR EQUIVALENT) IS CALLED AND THE SUBSET COUNT 15,16
<A NAME='READSB'><A href='../../html_code/bufr/ufbcnt.f.html#READSB' TARGET='top_target'><IMG SRC="../../gif/bar_red.gif" border=0></A>
C ADVANCES EACH TIME BUFR ARCHIVE LIBRARY SUBROUTINE READSB (OR 10,10
C EQUIVALENT) IS CALLED FOR A PARTICULAR MESSAGE. IF THE MESSAGE/
C SUBSET ARE BEING WRITTEN, THE MESSAGE COUNT ADVANCES EACH TIME

C BUFR ARCHIVE LIBRARY SUBROUTINE OPENMG (OR EQUIVALENT) IS CALLED 1,10
C AND THE SUBSET COUNT ADVANCES EACH TIME BUFR ARCHIVE LIBRARY
<A NAME='WRITSB'><A href='../../html_code/bufr/ufbcnt.f.html#WRITSB' TARGET='top_target'><IMG SRC="../../gif/bar_red.gif" border=0></A>
C SUBROUTINE WRITSB (OR EQUIVALENT) IS CALLED. 5,11

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 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
C USAGE: CALL UFBCNT
(LUNIT, KMSG, KSUB)
C INPUT ARGUMENT LIST:
C LUNIT - INTEGER: FORTRAN LOGICAL UNIT NUMBER FOR BUFR FILE
C
C OUTPUT ARGUMENT LIST:
C KMSG - INTEGER: POINTER TO MESSAGE COUNT IN BUFR FILE
C (INCLUDING MESSAGE CURRENTLY OPEN FOR READING/WRITING)
C KSUB - INTEGER: POINTER TO SUBSET COUNT IN BUFR MESSAGE
C (INCLUDING SUBSET CURRENTLY OPEN FOR READING/WRITING)
C
C REMARKS:
C IF AN APPLICATION PROGRAM DESIRES TO KNOW THE NUMBER OF SUBSETS IN
C A BUFR MESSAGES JUST OPENED, IT MUST USE THE FUNCTION NMSUB RATHER
C THAN THIS SUBROUTINE BECAUSE KSUB ONLY INCREMENTS BY ONE FOR EACH
C CALL TO READSB (I.E., KSUB = 0 IMMEDIATELY AFTER READMG IS
C CALLED).
C
C THIS ROUTINE CALLS: BORT STATUS
C THIS ROUTINE IS CALLED BY: UFBPOS
C Also called by application programs.

C LANGUAGE: FORTRAN 77
