C SUBPROGRAM:    BOUND       CLIPS DATA IN PASSED ARRAY
C   PRGRMMR: TREADON         ORG: W/NP2      DATE: 93-01-18
C     
C ABSTRACT:  THIS ROUTINE BOUNDS DATA IN THE PASSED ARRAY 
C   FLD (IMxJM ELEMENTS LONG) AND CLIPS DATA VALUES SUCH 
C   THAT ON EXITING THE ROUTINE 
C                FMIN <= FLD(I,J) <= FMAX
C   FOR ALL POINTS.
