Creates a random integer.

Synopsis

random limit | seed ?seedval?

Description

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 num- ber 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, pro- viding a reasonably interesting and ever-changing seed.
