SUBROUTINE TRYBUMP(LUNIT,LUN,USR,I1,I2,IO,IRET) 3,1
C$$$ SUBPROGRAM DOCUMENTATION BLOCK
C
C SUBPROGRAM: TRYBUMP
C PRGMMR: WOOLLEN ORG: NP20 DATE: 1994-01-06
C
C ABSTRACT: THIS SUBROUTINE CHECKS THE FIRST NODE ASSOCIATED WITH A
C CHARACTER STRING (PARSED INTO ARRAYS IN COMMON BLOCK /USRSTR/) IN
C ORDER TO DETERMINE IF IT REPRESENTS A DELAYED REPLICATION SEQUENCE.
C IF SO, THEN THE DELAYED REPLICATION SEQUENCE IS INITIALIZED AND
C EXPANDED (I.E. "BUMPED") TO THE VALUE OF INPUT ARGUMENT I2.
C A CALL IS THEN MADE TO SUBROUTINE UFBRW IN ORDER TO WRITE USER DATA
C INTO THE NEWLY EXPANDED REPLICATION SEQUENCE.
C
C TRYBUMP IS USUALLY CALLED FROM UFBINT AFTER UFBINT RECEIVES A
C NON-ZERO RETURN CODE FROM UFBRW. THE CAUSE OF A BAD RETURN FROM
C UFBRW IS USUALLY A DELAYED REPLICATION SEQUENCE WHICH ISN'T
C EXPANDED ENOUGH TO HOLD THE ARRAY OF DATA THE USER IS TRYING TO
C WRITE. SO TRYBUMP IS ONE LAST CHANCE TO RESOLVE THAT SITUATION.

C PROGRAM HISTORY LOG:
C 1994-01-06 J. WOOLLEN -- ORIGINAL AUTHOR
C 1998-07-08 J. WOOLLEN -- IMPROVED MACHINE PORTABILITY
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 -- MAXJL (MAXIMUM NUMBER OF JUMP/LINK ENTRIES)
C INCREASED FROM 15000 TO 16000 (WAS IN
C VERIFICATION VERSION); UNIFIED/PORTABLE FOR
C WRF; ADDED DOCUMENTATION (INCLUDING
C HISTORY) (INCOMPLETE); OUTPUTS MORE
C COMPLETE DIAGNOSTIC INFO WHEN ROUTINE
C TERMINATES ABNORMALLY
C 2009-03-31 J. WOOLLEN -- ADDED DOCUMENTATION

C USAGE: CALL TRYBUMP
(LUNIT, LUN, USR, I1, I2, IO, IRET)
C INPUT ARGUMENT LIST:
C LUNIT - INTEGER: FORTRAN LOGICAL UNIT NUMBER FOR BUFR FILE
C (SEE REMARKS)
C LUN - INTEGER: I/O STREAM INDEX INTO INTERNAL MEMORY ARRAYS
C (ASSOCIATED WITH FILE CONNECTED TO LOGICAL UNIT LUNIT)
C USR - REAL*8: (I1,I2) STARTING ADDRESS OF DATA VALUES TO BE
C WRITTEN TO DATA SUBSET
C I1 - INTEGER: LENGTH OF FIRST DIMENSION OF USR
C I2 - INTEGER: NUMBER OF "LEVELS" OF DATA VALUES TO BE
C WRITTEN TO DATA SUBSET
C IO - INTEGER: STATUS INDICATOR FOR BUFR FILE ASSOCIATED
C WITH LUNIT (SEE REMARKS):
C 0 = INPUT FILE (POSSIBLE FUTURE USE)
C 1 = OUTPUT FILE
C
C OUTPUT ARGUMENT LIST:
<A NAME='UFBRW'><A href='../../html_code/bufr/trybump.f.html#UFBRW' TARGET='top_target'><IMG SRC="../../gif/bar_red.gif" border=0></A>
C IRET - INTEGER: RETURN CODE FROM CALL TO SUBROUTINE UFBRW 3,4
C
C REMARKS:
C ARGUMENT LUNIT IS NOT REFERENCED IN THIS SUBROUTINE. IT WAS
C INCLUDED ONLY FOR POTENTIAL FUTURE EXPANSION OF THE SUBROUTINE.
C
C ARGUMENT IO IS ALWAYS PASSED IN WITH A VALUE OF 1 AT THE PRESENT
C TIME. IN THE FUTURE THE SUBROUTINE MAY BE EXPANDED TO ALLOW IT
C TO OPERATE ON INPUT FILES.
