SUBROUTINE UFBMEX(LUNIT,LUNDX,INEW,IRET,MESG) 1,20
C$$$ SUBPROGRAM DOCUMENTATION BLOCK
C
C SUBPROGRAM: UFBMEX
C PRGMMR: WOOLLEN ORG: NP20 DATE: 2012-01-26
C
C ABSTRACT: THIS SUBROUTINE OPENS A BUFR FILE FOR INPUT, READS EACH
C MESSAGE AND TRANSFERS THEM ONE-BY-ONE TO INTERNAL MEMORY (ARRAY
C MSGS IN COMMON BLOCK /MSGMEM/). IF MESSAGES ARE APPENDED TO
C EXISTING MESSAGES IN INTERNAL MEMORY, THE BUFR FILE READ HERE IS
C CLOSED PRIOR TO RETURNING TO THE CALLING PROGRAM. AN ARRAY IS
C ALSO RETURNED CONTAINING A LIST OF MESSAGE TYPES READ IN.
C
C THIS IS A VARIATION OF UFBMEM WHICH ENABLES MESSAGE SORTING BEFORE
C READING. BECAUSE OF THIS RE-ORDERING, EMBEDDED TABLE MESSAGES ARE
C NOT STORED IN COMMON /MSGMEM/, SINCE THEY ARE NO LONGER RELEVANT
C ONCE THE RE-ORDERING (I.E. SORTING) HAS TAKEN PLACE. INSTEAD, A
C SEPARATE UNIT NUMBER IS ADDED TO THE INPUT ARGUMENTS TO SPECIFY
C WHERE THE NECESSARY BUFR TABLE INFORMATION CAN BE FOUND.
C
C PROGRAM HISTORY LOG:
C 2012-01-26 J. WOOLLEN -- MODIFIED UFBMEM TO READ AND SORT MEMORY
C MESSAGES FOR TRANJB INGEST ROUTINES AND
C RETURN A LIST OF MESSAGE TYPES READ IN.
C ALSO, A SEPARATE INPUT ARGUMENT IS ADDED
C TO SPECIFY WHERE TO FIND THE BUFR TABLE,
C INSTEAD OF SAVING EMBEDDED DICTIONARY
C MESSAGES IN COMMON /MSGMEM/
C
C USAGE: CALL UFBMEX
(LUNIT, LUNDX, INEW, IRET, MESG)
C INPUT ARGUMENT LIST:
C LUNIT - INTEGER: FORTRAN LOGICAL UNIT NUMBER FOR BUFR FILE
C LUNDX - INTEGER: FORTRAN LOGICAL UNIT NUMBER FOR USER-
C SUPPLIED BUFR DICTIONARY TABLE IN CHARACTER FORMAT
C INEW - INTEGER: SWITCH:
C 0 = initialize internal arrays prior to
C transferring messages here
C else = append the messages transferred here to
C internal memory arrays
C
C OUTPUT ARGUMENT LIST:
C IRET - INTEGER: NUMBER OF MESSAGES TRANSFERRED
C MESG - INTEGER: ARRAY OF MESSAGE TYPES READ INTO MEMORY
C
C INPUT FILES:
C UNIT "LUNIT" - BUFR FILE
C UNIT "LUNDX" - BUFR DICTIONARY TABLE IN CHARACTER FORMAT
C
C REMARKS:
C NOTE THAT IREADMM, RDMEMM, READMM, UFBMMS, UFBMNS, UFBRMS, UFBTAB
C OR UFBTAM CAN BE CALLED AFTER THIS TO READ SPECIFIC BUFR MESSAGES
C FROM INTERNAL MEMORY.

C THIS ROUTINE IS CALLED BY: None
C Normally called only by application
C programs.
