Paul,

a couple of comments:

1. Swarm was not designed to run on the old Pet computer ;-) 
(Commodore is long gone!)

2. You must be aware that if all you want is doubles uniformly distributed
over [0.0,1.0) you don't need to call the distribution object at all; any
generator will give you that with

        randNum = [randomGenerator getDoubleSample];

or, if you don't need full precision, 

        randNum = [randomGenerator getThinDoubleSample];

3. Beyond that, the behavior you describe is troubling. Please tell us more
about the hardware and software environment provided by your laptop.

Sven
