#! /bin/csh

@ rng = `date | tr : ' ' | awk '{ print $3 * $4 * $5 * $6}'` + $$

echo $rng

Gives "reasonable" oneshot random numbers. If you need a mess of them,
then take $rng, and a LCG (did I get the term right???):

@rng = $rng * something + something_else

which might keep you happy. Failing this, get on with Knuth Volume 2 and
awk.
