SUBROUTINE NEMTBD(LUN,ITAB,NSEQ,NEMS,IRPS,KNTS) 6,15
C$$$ SUBPROGRAM DOCUMENTATION BLOCK
C
C SUBPROGRAM: NEMTBD
C PRGMMR: WOOLLEN ORG: NP20 DATE: 1994-01-06
C
C ABSTRACT: THIS SUBROUTINE RETURNS A LIST OF THE MNEMONICS (I.E.,
C "CHILD" MNEMONICS) CONTAINED WITHIN A TABLE D SEQUENCE MNEMONIC
C (I.E., A "PARENT MNEMONIC"). THIS INFORMATION SHOULD HAVE BEEN
C PACKED INTO THE INTERNAL BUFR TABLE D ENTRY FOR THE PARENT MNEMONIC
C (IN COMMON BLOCK /TABABD/) VIA PREVIOUS CALLS TO BUFR ARCHIVE
C LIBRARY SUBROUTINE PKTDD. NOTE THAT NEMTBD DOES NOT RECURSIVELY
C RESOLVE CHILD MNEMONICS WHICH ARE THEMSELVES TABLE D SEQUENCE
C MNEMONICS; RATHER, SUCH RESOLUTION MUST BE DONE VIA SEPARATE
C SUBSEQUENT CALLS TO THIS SUBROUTINE.
C
C PROGRAM HISTORY LOG:
C 1994-01-06 J. WOOLLEN -- ORIGINAL AUTHOR
C 1995-06-28 J. WOOLLEN -- INCREASED THE SIZE OF INTERNAL BUFR TABLE
C ARRAYS IN ORDER TO HANDLE BIGGER FILES
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 2000-09-19 J. WOOLLEN -- MUST NOW CHECK FOR TABLE C (OPERATOR
C DESCRIPTOR) MNEMONICS SINCE THE CAPABILITY
C HAS NOW BEEN ADDED TO ENCODE AND DECODE
C THESE
C 2003-11-04 J. ATOR -- ADDED DOCUMENTATION
C 2003-11-04 S. BENDER -- ADDED REMARKS/BUFRLIB ROUTINE
C INTERDEPENDENCIES
C 2003-11-04 D. KEYSER -- UNIFIED/PORTABLE FOR WRF; ADDED HISTORY
C DOCUMENTATION; OUTPUTS MORE COMPLETE
C DIAGNOSTIC INFO WHEN ROUTINE TERMINATES
C ABNORMALLY
C
C USAGE: CALL NEMTBD
(LUN, ITAB, NSEQ, NEMS, IRPS, KNTS)
C INPUT ARGUMENT LIST:
C LUN - INTEGER: I/O STREAM INDEX INTO INTERNAL MEMORY ARRAYS
C ITAB - INTEGER: POSITIONAL INDEX OF PARENT MNEMONIC WITHIN
C INTERNAL BUFR TABLE D ARRAY TABD(*,*)
C
C OUTPUT ARGUMENT LIST:
C NSEQ - INTEGER: TOTAL NUMBER OF CHILD MNEMONICS FOR THE
C PARENT MNEMONIC GIVEN BY TABD(ITAB,LUN)
C NEMS - CHARACTER*8: (NSEQ)-WORD ARRAY OF CHILD MNEMONICS
C IRPS - INTEGER: (NSEQ)-WORD RETURN VALUE ARRAY (SEE REMARKS)
C KNTS - INTEGER: (NSEQ)-WORD RETURN VALUE ARRAY (SEE REMARKS)
C
C REMARKS:
C VALUE FOR OUTPUT ARGUMENT IRPS:
C The interpretation of the return value IRPS(I) depends upon the
C type of descriptor corresponding to NEMS(I), as follows:
C
C IF ( NEMS(I) corresponds to an F=1 regular (i.e. non-delayed)
C replication descriptor ) THEN
C IRPS(I) = 1
C ELSE IF ( NEMS(I) corresponds to a delayed replicator or
C replication factor descriptor ) THEN
C IRPS(I) = positional index of corresponding descriptor
C within internal replication array IDNR(*,*)
C ELSE
C IRPS(I) = 0
C END IF
C
C
C VALUE FOR OUTPUT ARGUMENT KNTS:
C The interpretation of the return value KNTS(I) depends upon the
C type of descriptor corresponding to NEMS(I), as follows:
C
C IF ( NEMS(I) corresponds to an F=1 regular (i.e. non-delayed)
C replication descriptor ) THEN
C KNTS(I) = number of replications
C ELSE
C KNTS(I) = 0
C END IF
