 There is a +D/MOD in this link

Thanks, Gerry. It looks like D/MOD is not essential to computing the binomial coefficients with double length numbers. We can use M*/ for single computations, or simply D+ to build up a table of coefficients. But, it's good to have a reference for D/MOD.
I remember that I wanted to update the FSL R250 code to generate 64-bit random numbers, but I never got around to it. There is also a permutations and combinations module in FSL which may benefit from what has been demonstrated in this thread.
