C$$$ SUBPROGRAM DOCUMENTATION BLOCK
C
C SUBPROGRAM: TRYBUMP (docblock incomplete)
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, IT IS
C "BUMPED" TO THE VALUE OF INPUT ARGUMENT I2, AND AN ATTEMPT IS MADE
C TO READ OR WRITE SPECIFIED VALUES TO THE CURRENT BUFR DATA SET IN
C UNIT LUNIT.
C
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
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 READ
C FROM OR WRITTEN TO DATA SUBSET
C I1 - INTEGER: LENGTH OF FIRST DIMENSION OF USR
C I2 - INTEGER: IF READING, LENGTH OF SECOND DIMENSION OF
C USR; IF WRITING, NUMBER OF "LEVELS" OF DATA VALUES TO
C BE WRITTEN TO DATA SUBSET
C IO - INTEGER: STATUS INDICATOR FOR BUFR FILE ASSOCIATED
C WITH LUNIT:
C 0 = input file
C 1 = output file
C
C OUTPUT ARGUMENT LIST:
C IRET - INTEGER: NUMBER OF "LEVELS" OF DATA VALUES READ FROM
C OR WRITTEN TO DATA SUBSET (IF READING SHOULD BE NO
C LARGER THAN I2, IF WRITING SHOULD BE SAME AS I2)
C -1 = ....
C
C REMARKS:
C ARGUMENT LUNIT IS NOT REFERENCED IN THIS SUBROUTINE. IT IS LEFT
C HERE IN CASE AN APPLICATION PROGRAM CALLS THIS SUBROUTINE.

C THIS ROUTINE IS CALLED BY: UFBINT UFBOVR
C Normally not called by any application
C programs.
