random --
return pseudo-random positive integer
Synopsis
random limit | seed [seedval]
Description
Generates a pseudo-random 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 you to reproduce
pseudo-random 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.
