       random limit | seed ?seedval?
              Generate a pseudorandom integer number greater than
              or equal to zero and less than limit.  If  seed  is
              specified,  then  the  command  resets  the  random
              number generator to a starting point  derived  from
              the   seedval.   This   allows   one  to  reproduce
              pseudorandom number sequences for testing purposes.
              If  seedval  is  omitted, then the seed is set to a
              value based on current system state and the current
              time,  providing a reasonably interesting and ever-
              changing seed.
