C ABSTRACT: THIS SUBROUTINE STORES THE SUBSET TEMPLATE INTO INTERNAL
C SUBSET ARRAYS IN COMMON BLOCKS /USRINT/ AND /USRBIT/. THIS IS IN
C PREPARATION FOR THE ACTUAL UNPACKING OF THE SUBSET IN BUFR ARCHIVE
C LIBRARY SUBROUTINE RDTREE.

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 1998-10-27 J. WOOLLEN -- MODIFIED TO CORRECT PROBLEMS CAUSED BY IN-
C LINING CODE WITH FPP DIRECTIVES
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 2000-09-19 J. WOOLLEN -- MAXIMUM MESSAGE LENGTH INCREASED FROM
C 10,000 TO 20,000 BYTES
C 2002-05-14 J. WOOLLEN -- REMOVED OLD CRAY COMPILER DIRECTIVES
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); MAXRCR (MAXIMUM
C NUMBER OF RECURSION LEVELS) INCREASED FROM
C 50 TO 100 (WAS IN VERIFICATION VERSION);
C UNIFIED/PORTABLE FOR WRF; ADDED
C DOCUMENTATION (INCLUDING HISTORY); OUTPUTS
C MORE COMPLETE DIAGNOSTIC INFO WHEN ROUTINE
C TERMINATES ABNORMALLY; COMMENTED OUT
C HARDWIRE OF VTMP TO "BMISS" (10E10) WHEN IT
C IS > 10E9 (CAUSED PROBLEMS ON SOME FOREIGN
C MACHINES)
C 2004-08-09 J. ATOR -- MAXIMUM MESSAGE LENGTH INCREASED FROM
C 20,000 TO 50,000 BYTES
C
