    Hi.
    What do these manual lines mean?

    WHAT(1) : controls the step optimization for multiple scattering,
              and the number of (possible) single scatterings on a material
              by material basis
           <= -1.0 : a possible previous request of optimization is
                     cancelled and the number of single scatterings is reset to
                     the default value (the global one set by this option with
                     GLOBAL/GLOBHAD/GLOBEMF)
            = 0.0 : ignored
            = I0 + I1*10 + I2*100000
              (with 0=< I0 =<1, 0=< I1 <10000, 0 =< I2 < 10000):
              I0 >= 1 : the optimization is activated
              I1 - 1 = number of single scattering steps for hadrons and
                         muons in the materials indicated by WHAT(4)-WHAT(6)
              I1 = 0 : ignored
              I2 - 1 = number of single scattering steps for electrons and
                         positrons in the materials indicated by
                         WHAT(4)-WHAT(6)
              I2 = 0 : ignored

            Default: 0.0 (no multiple scattering optimization and no single
                          scattering)

    If I understood well, 300021 means that optimization is active and that I
    have at most 2 single scattering for electrons and positrons and only one
    for muons and hadrons.
    Is it right?
    Thank you,

            Luillo
