What do you mean by complex.

Your meaning is not clear, D[x_,n] defines a function for a fixed  
variable n, I think you meant D[x_,n_].  Secondly is D supposed to  
have side effects?  What is the purpose of assigning its value to  
itself?  Third, s only has value within the Do loop, do you mean to  
return D[x,n]?  Fourth, why clear D?  In short the pseudocode raises  
more questions than one could answer.
