C> THIS SUBROUTINE READS IN A FXY DESCRIPTOR ENTRY (Y) FOR A
C>   SEQUENCE DESCRIPTOR (F=3) WITH TABLE D CATEGORY 63 (X=63) WHEN THE
C>   DESCRIPTOR IS KNOWN TO BE IN THE BUFR TABLE IN LOGICAL UNIT LUNIT,
C>   AND RETURNS THE MNEMONIC ASSOCIATED WITH IT.  THIS ROUTINE WILL NOT
C>   WORK FOR ANY OTHER TYPE OF DESCRIPTOR OR ANY OTHER SEQUENCE
C>   DESCRIPTOR TABLE D CATEGORY.  LUNIT MUST ALREADY BE OPENED FOR
C>   INPUT OR OUTPUT VIA A CALL TO BUFR ARCHIVE LIBRARY SUBROUTINE
C>   OPENBF.  THIS ROUTINE IS ESPECIALLY USEFUL WHEN THE CALLING PROGRAM
C>   IS READING "EVENTS" FROM AN INPUT BUFR FILE IN LUNIT (USUALLY THE
C>   "PREPBUFR" FILE) SINCE THE DESCRIPTOR ENTRY (Y) HERE DEFINES THE
C>   EVENT PROGRAM CODE.  THUS, THE CALLING PROGRAM CAN OBTAIN THE
C>   MNEMONIC NAME ASSOCIATED WITH AN EVENT PROGRAM CODE.

C> USAGE:    CALL UFBQCP (LUNIT, QCP, NEMO)
C>   INPUT ARGUMENT LIST:
C>     LUNIT    - INTEGER: FORTRAN LOGICAL UNIT NUMBER FOR BUFR FILE
C>                (ASSOCIATED BUFR TABLE MAY BE INTERNAL OR EXTERNAL)
C>     QCP      - REAL: SEQUENCE DESCRIPTOR ENTRY (I.E., EVENT PROGRAM
C>                CODE) (Y IN FXY DESCRIPTOR)
C>
C>   OUTPUT ARGUMENT LIST:
C>     NEMO     - CHARACTER*(*): MNEMONIC IN BUFR TABLE ASSOCIATED WITH
C>                SEQUENCE DESCRIPTOR FXY WHERE F=3 AND X=63 AND
C>                Y=INT(QCP)

C>    THIS SUBROUTINE IS THE INVERSE OF BUFR ARCHIVE LIBRARY ROUTINE
C>    UFBQCD.
