I know there are various functions in SAS to let me sample from abinomial distribution, but I can't seem to find something simple to give me the binomial coefficient alone. Is there such a function that I'm simply missing?

I ask because I'm writing some MCMC macros, and for one of the problems, need to derive the binomial coefficient, and am stuck at this point (heck, I can't even find a SAS function to calculate a factorial N!).

Thanks in advance...
