Fine. So let's do it this way.

Yes, stack lift should be implemented. Not only because it is required by some of the programs.
And do not forget the final ABS. ;-)

BTW, what happens if R00 contains alpha data? Could this be converted to some kind of numeric value?

I wonder if we could squeeze out some more digits if the multiplication is done with 13-digit precision. This does not mean the RNG gets a longer period, it still is 10^6. But I think we should get three more digits if we change the increment to 0,211327003 or 0,211327157 (10^9 times this prime). As far as I understand the theory of linear congruential RNGs (cf. Knuth) this should yield the maximum period, i.e. 10^9.
