FUNCTION INVWIN(NODE,LUN,INV1,INV2) 11,4
C$$$ SUBPROGRAM DOCUMENTATION BLOCK
C
C SUBPROGRAM: INVWIN
C PRGMMR: WOOLLEN ORG: NP20 DATE: 1994-01-06
C
C ABSTRACT: THIS FUNCTION LOOKS FOR A SPECIFIED NODE WITHIN THE PORTION
C OF THE CURRENT SUBSET BUFFER BOUNDED BY THE INDICES INV1 AND INV2.
C IT IS SIMILAR TO BUFR ARCHIVE LIBRARY FUNCTION INVTAG, EXCEPT THAT
C INVTAG SEARCHES BASED ON THE MNEMONIC CORRESPONDING TO THE NODE.
C
C PROGRAM HISTORY LOG:
C 1994-01-06 J. WOOLLEN -- ORIGINAL AUTHOR
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 UNUSUAL THINGS HAPPEN
C 2009-03-31 J. WOOLLEN -- ADDED DOCUMENTATION
C 2009-04-21 J. ATOR -- USE ERRWRT
C
C USAGE: INVWIN (NODE, LUN, INV1, INV2)
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
C OUTPUT ARGUMENT LIST:
C INVWIN - INTEGER: LOCATION INDEX OF NODE WITHIN SPECIFIED
C PORTION OF SUBSET BUFFER
C 0 = NOT FOUND
