subroutine trybump	(		LUNIT,
			LUN,
		real*8, dimension(i1,i2)	USR,
			I1,
			I2,
			IO,
			IRET
	)

THIS SUBROUTINE CHECKS THE FIRST NODE ASSOCIATED WITH A CHARACTER STRING (PARSED INTO ARRAYS IN COMMON BLOCK /USRSTR/) IN ORDER TO DETERMINE IF IT REPRESENTS A DELAYED REPLICATION SEQUENCE.

IF SO, THEN THE DELAYED REPLICATION SEQUENCE IS INITIALIZED AND EXPANDED (I.E. "BUMPED") TO THE VALUE OF INPUT ARGUMENT I2. A CALL IS THEN MADE TO SUBROUTINE UFBRW IN ORDER TO WRITE USER DATA INTO THE NEWLY EXPANDED REPLICATION SEQUENCE.

TRYBUMP IS USUALLY CALLED FROM UFBINT AFTER UFBINT RECEIVES A NON-ZERO RETURN CODE FROM UFBRW. THE CAUSE OF A BAD RETURN FROM UFBRW IS USUALLY A DELAYED REPLICATION SEQUENCE WHICH ISN'T EXPANDED ENOUGH TO HOLD THE ARRAY OF DATA THE USER IS TRYING TO WRITE. SO TRYBUMP IS ONE LAST CHANCE TO RESOLVE THAT SITUATION.

WOOLLEN – THE NUMBER OF BUFR FILES WHICH CAN BE OPENED AT ONE TIME INCREASED FROM 10 TO 32 (NECESSARY IN ORDER TO PROCESS MULTIPLE BUFR FILES UNDER THE MPI) 2003-11-04 S. BENDER – ADDED REMARKS/BUFRLIB ROUTINE INTERDEPENDENCIES 2003-11-04 D. KEYSER – MAXJL (MAXIMUM NUMBER OF JUMP/LINK ENTRIES) INCREASED FROM 15000 TO 16000 (WAS IN VERIFICATION VERSION); UNIFIED/PORTABLE FOR WRF; ADDED DOCUMENTATION (INCLUDING HISTORY) (INCOMPLETE); OUTPUTS MORE COMPLETE DIAGNOSTIC INFO WHEN ROUTINE TERMINATES ABNORMALLY 2009-03-31 J. WOOLLEN – ADDED DOCUMENTATION 2014-12-10 J. ATOR – USE MODULES INSTEAD OF COMMON BLOCKS

USAGE: CALL TRYBUMP (LUNIT, LUN, USR, I1, I2, IO, IRET) INPUT ARGUMENT LIST: LUNIT - INTEGER: FORTRAN LOGICAL UNIT NUMBER FOR BUFR FILE (SEE REMARKS) LUN - INTEGER: I/O STREAM INDEX INTO INTERNAL MEMORY ARRAYS (ASSOCIATED WITH FILE CONNECTED TO LOGICAL UNIT LUNIT) USR - REAL*8: (I1,I2) STARTING ADDRESS OF DATA VALUES TO BE WRITTEN TO DATA SUBSET I1 - INTEGER: LENGTH OF FIRST DIMENSION OF USR I2 - INTEGER: NUMBER OF "LEVELS" OF DATA VALUES TO BE WRITTEN TO DATA SUBSET IO - INTEGER: STATUS INDICATOR FOR BUFR FILE ASSOCIATED WITH LUNIT (SEE REMARKS): 0 = INPUT FILE (POSSIBLE FUTURE USE) 1 = OUTPUT FILE

OUTPUT ARGUMENT LIST: IRET - INTEGER: RETURN CODE FROM CALL TO SUBROUTINE UFBRW

REMARKS: ARGUMENT LUNIT IS NOT REFERENCED IN THIS SUBROUTINE. IT WAS INCLUDED ONLY FOR POTENTIAL FUTURE EXPANSION OF THE SUBROUTINE.

ARGUMENT IO IS ALWAYS PASSED IN WITH A VALUE OF 1 AT THE PRESENT TIME. IN THE FUTURE THE SUBROUTINE MAY BE EXPANDED TO ALLOW IT TO OPERATE ON INPUT FILES.

THIS ROUTINE CALLS: BORT INVWIN LSTJPB UFBRW USRTPL THIS ROUTINE IS CALLED BY: UFBINT UFBOVR Normally not called by any application programs.
