You define b01 below: > b01_mod a b = a mod b You must type that "mod a b" or "a `mod` b". > main = do > (cmd:ss) <- getArgs > putStrLn ( > if (cmd == "mod") then do You don't need the "do" here. Since the type of the entire "if" statement is a String (not an IO String) this is an error. > show (b01_mod (read (ss!!1)) (read (ss!!2))) > else do > "unknown command!") > > Please, send me somethung like this (I need to understand it).

The program will crash with a meaningless error if they don't enter any args. peace, isaac _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
