Map a pure function such as f[[#]]&. For instance, depending on whether the expression holds some values before the mapping or not, In[1]:= f = {1.1, 1.2, 1.3}; (f[[#1]] & ) /@ Range[3] Out[2]= {1.1, 1.2, 1.3} In[3]:= (HoldForm[g[[#1]]] & ) /@ Range[3] g = {1, 2, 3}; ReleaseHold[%%] Out[3]= {HoldForm[g[[1]]], HoldForm[g[[2]]], HoldForm[g[[3]]]} Out[5]= {1, 2, 3} Regards, -- Jean-Marc
