Scramble Seed Keyword

<ScrambleSeed N>
<ss N>

    I parameter alternative. See Scrambling. N is used as a seed to the random number routines that determine the movement of items in a scramble. If there is no <ScrambleSeed> N is determined from the current time effectively yielding a different scramble each time DMDX is run.

  This is the same random number generator used for the random() function in the <SetCounter> keyword so if you want random numbers there you'll want to randomize the random number generator after the scramble, see <Randomize>.
