In[1]:= data = ToString /@ Range[3]; In[2]:= StringJoin @@ Riffle[data, " "] Out[2]= 1 2 3 For what it is worth, I've been using Mathematica on a daily basis for the past 10-20 years. And the only times I can recall using For were to show someone just how much slower code runs in Mathematica when using For instead of functional programming.
