in thread JAPH randomness

I knew computer randomizers were pseudo-random, it just surprised me how pseudo it was, to be able to seed the generator and come up with the same number every single time. I thought that on a system running multiple processes, the length of time to execute commands would vary marginally to produce a set (3, 6?) of "random" numbers that reliably comes up.
Hopefully the days of truly random numbers on computers comes soon.

    OTOH, seeding the random number generator to allways get back the same results is very handy during testing.
