Re: [Chicken-users] srfi-27 - producing pseudo and truly random numbers over a uniform distribution

[Ivan Raikov]

  Uniformly-distributed integers can be generated with the
random-mtzig:random! procedure. I do need to make the example
consistent with the API, thanks for pointing that out. Initially, the
procedures in that egg were not reentrant, and the state was global. I
forgot to update the example when I changed the procedures to have a
state variable argument. It looks like your code might work; why don't
you run it and see? Meanwhile, I will update the documentation.
