This just came to my mind: x[t_]:=x[t]=Random[] f[t_]:=Length[NestWhileList[# + x[#] &, 0, # <= t &]] But this is quite crazy!! It generates the list but not indexed by integers but by some real numbers (increasing, if only we don't get a '0'...). To Norbert Marxer: What if I want to plot this function? Saving the values of x for later is mandatory. Thanks to everybody for answers, P. Kaminski
