FUNCTION NVNWIN(NODE,LUN,INV1,INV2,INVN,NMAX) 1,5
C$$$ SUBPROGRAM DOCUMENTATION BLOCK
C
C SUBPROGRAM: NVNWIN
C PRGMMR: WOOLLEN ORG: NP20 DATE: 1994-01-06
C
C ABSTRACT: THIS FUNCTION LOOKS FOR AND RETURNS ALL OCCURRENCES OF A
C SPECIFIED NODE WITHIN THE PORTION OF THE CURRENT SUBSET BUFFER
C BOUNDED BY THE INDICES INV1 AND INV2. THE RESULTING LIST IS A
C STACK OF "EVENT" INDICES FOR THE REQUESTED NODE.
C
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 -- 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); OUTPUTS MORE COMPLETE DIAGNOSTIC
C INFO WHEN ROUTINE TERMINATES ABNORMALLY OR
C UNUSUAL THINGS HAPPEN
C 2009-03-23 J. ATOR -- USE 1E9 TO PREVENT OVERFLOW WHEN
C INITIALIZING INVN; USE ERRWRT
C 2009-03-31 J. WOOLLEN -- ADDED DOCUMENTATION
C
C USAGE: NVNWIN (NODE, LUN, INV1, INV2, INVN, NMAX)
C INPUT ARGUMENT LIST:
C NODE - INTEGER: JUMP/LINK TABLE INDEX TO LOOK FOR
C LUN - INTEGER: I/O STREAM INDEX INTO INTERNAL MEMORY ARRAYS
C INV1 - INTEGER: STARTING INDEX OF THE PORTION OF THE SUBSET
C BUFFER IN WHICH TO LOOK
C INV2 - INTEGER: ENDING INDEX OF THE PORTION OF THE SUBSET
C BUFFER IN WHICH TO LOOK
C NMAX - INTEGER: DIMENSIONED SIZE OF INVN; USED BY THE
C FUNCTION TO ENSURE THAT IT DOES NOT OVERFLOW THE
C INVN ARRAY
C
C OUTPUT ARGUMENT LIST:
C INVN - INTEGER: ARRAY OF STACK "EVENT" INDICES FOR NODE
C NVNWIN - INTEGER: NUMBER OF INDICES RETURNED WITHIN INVN
C
C REMARKS:
C THIS ROUTINE CALLS: BORT ERRWRT
C THIS ROUTINE IS CALLED BY: UFBEVN
C Normally not called by any application
C programs.
