   8 C ABSTRACT: THIS SUBROUTINE IS CALLED BY BUFR ARCHIVE LIBRARY SUBROUTINE
   9 C   UFBRW WHENEVER IT CAN'T FIND A MNEMONIC IT WANTS TO WRITE WITHIN THE
  10 C   CURRENT SUBSET BUFFER.  IT LOOKS FOR THE MNEMONIC WITHIN ANY
  11 C   UNEXPANDED "DRS" (STACK) OR "DRB" (1-BIT DELAYED REPLICATION)
  12 C   SEQUENCES INSIDE OF THE PORTION OF THE SUBSET BUFFER BOUNDED BY THE
  13 C   INDICES INV1 AND INV2.  IF FOUND, IT EXPANDS THE APPLICABLE "DRS" OR
  14 C   "DRB" SEQUENCE TO THE POINT WHERE THE MNEMONIC IN QUESTION NOW
  15 C   APPEARS IN THE SUBSET BUFFER, AND IN DOING SO IT WILL ALSO RETURN
  16 C   A NEW VALUE FOR INV2.

  19 C 1994-01-06  J. WOOLLEN -- ORIGINAL AUTHOR
  20 C 1998-07-08  J. WOOLLEN -- REPLACED CALL TO CRAY LIBRARY ROUTINE
  21 C                           "ABORT" WITH CALL TO NEW INTERNAL BUFRLIB
  22 C                           ROUTINE "BORT" (LATER REMOVED, UNKNOWN
  23 C                           WHEN)
  24 C 2002-05-14  J. WOOLLEN -- REMOVED OLD CRAY COMPILER DIRECTIVES
  25 C 2003-11-04  S. BENDER  -- ADDED REMARKS/BUFRLIB ROUTINE

  27 C 2003-11-04  D. KEYSER  -- MAXJL (MAXIMUM NUMBER OF JUMP/LINK ENTRIES)
  28 C                           INCREASED FROM 15000 TO 16000 (WAS IN
  29 C                           VERIFICATION VERSION); UNIFIED/PORTABLE FOR
  30 C                           WRF; ADDED DOCUMENTATION (INCLUDING

  34 C USAGE:    CALL DRSTPL (INOD, LUN, INV1, INV2, INVN)
  35 C
  36 C   INPUT ARGUMENT LIST:
  37 C     INOD     - INTEGER: JUMP/LINK TABLE INDEX OF MNEMONIC TO LOOK FOR
  38 C     LUN      - INTEGER: I/O STREAM INDEX INTO INTERNAL MEMORY ARRAYS
  39 C     INV1     - INTEGER: STARTING INDEX OF THE PORTION OF THE SUBSET
  40 C                BUFFER CURRENTLY BEING PROCESSED BY UFBRW
  41 C     INV2     - INTEGER: ENDING INDEX OF THE PORTION OF THE SUBSET
  42 C                BUFFER CURRENTLY BEING PROCESSED BY UFBRW
  43 C
  44 C   OUTPUT ARGUMENT LIST:
  45 C     INVN     - INTEGER: LOCATION INDEX OF INOD WITHIN SUBSET BUFFER:
  46 C                  0 = NOT FOUND
  47 C     INV2     - INTEGER: IF INVN = 0, THEN INV2 IS UNCHANGED FROM ITS
  48 C                INPUT VALUE.  OTHERWISE, IT CONTAINS THE REDEFINED
  49 C                ENDING INDEX OF THE PORTION OF THE SUBSET BUFFER
  50 C                CURRENTLY BEING PROCESSED BY UFBRW, SINCE EXPANDING A
  51 C                DELAYED REPLICATION SEQUENCE WILL HAVE NECESSARILY
  52 C                INCREASED THE SIZE OF THIS BUFFER.
