As Martin already said, there is no way in which you can
see what in-built commands do. Based on your previous 
questions I suppose that you are primarily interested in
what the -invnormal()- function does. It returns the 
inverse cumulative standard normal distribution. As you
know there is no closed form solution to that integral, 
so my guess is that it either looks up values from an
internally stored table, or it uses some approximation
