Sorry, but no, it isn't quite the same as I understand them. S-PLUS
skips members of the sequence occasionally. But it depends what you
mean here: S-PLUS != S and I very much doubt you have S.

I don't know why you want to do this: if you use any of the built-in
operations (such as rnorm) you will get different answers as different
algorithms are used.  If all you want is a stream of runif() type,
implement your version on both systems to be sure.
