Could you be more specific? Paste the code you have already, and be clearer about what you are trying to accomplish. Luke

Maybe something like this? pairs :: String -> [(String,Integer)] pairs s = f (words s) [] where f [] acc = reverse acc f (i:[]) acc = reverse ((i,undefined):acc) f (i:v:r) acc = f r ((i,read v):acc) Key points to look at: accumulator (acc with cons : ), recursion (f), pattern matching (i:v:r), undefined (if the data is not pairs).
