  4.                Generate a pseudorandom integer number greater than  or
  5.                equal  to  zero and less than limit.  If seed is speci-
  6.                fied, then the command resets the random number genera-
  7.                tor  to a starting point derived from the seedval. This
  8.                allows one to reproduce pseudorandom  number  sequences
