Hi, What I needed was actualy something more like f3 :: Int -> String f3 x = show x ++ f4 x f4 :: Int -> IO String f4 x = do putStr ("initial value is " ++ show x) return (show x) but this gives the error Type checking ERROR "teste.hs":11 - Type error in application *** Expression : show x ++ f4 x *** Term : f4 x *** Type : IO String *** Does not match : [a] Can you help me? Thank you
