    Description :
    ____________

    Depending on the data, this operator generate LISTREEL, EVOL
or CHAMPOIN with random values.

    Contents :
    __________


    'BLAN' : key word for random values with no correlation.

    MOT1   : type of values distribution chosen from the words :
                    'GAUS'      gaussian
                    'UNIF'      uniform
                    'EXPO'      exponential

    FLOT1  : mean value of the generated values (FLOTTANT type)
             This mean value is not taken into account for
             distributions of exponential type.

    FLOT2  : standard deviation ('GAUS' and 'EXPO' options) or
             amplitude  ('UNIF' option)
             (FLOTTANT type)

    ENTI1  : length of the LISTREEL RESU1 (ENTIER type).
    or
    LREEL1 : signal time-variable of the EVOLUTION RESU1
             (LISTREEL type).
    or
    GEO1   : geometrical support of the CHAMPOIN RESU1 (MAILLAGE type).

    COUL1  : curve color if LRREL1 is given (MOT type; default 'BLAN').

    ENTI2  : index enabling the user to change the random signal
             from a calculation to the other (ENTIER type)

    RESU1  : result, LISTREEL type if ENTI1 is given,
             or EVOLUTION type if LRREL1 is given,
             or CHAMPOIN type if GEO1 is given.

    Remarks :
    _________

    1) With the ENTI2 index, you jump ENTI2 values calculated by the
random generator. You have to use this option when you restart a run
because at each run the generator restart from the same first value.

    2) If BRUI is called in a loop, each result will be distinct
from the previous one. So, don't use the ENTI2 option, the generator
is self-adjusted.
