Hi, This line: print_int fac(6);; Can be read as: print_int fac 6;; That is 2 arguments whereas print_int expects exactly 1 argument. The corrected line is: print_int (fac 6);; Note that function application is just juxtaposition, parenthesis are unneded. Regards, - damien hi I try to make my first steps with Ocaml and I have some difficulties. I know there is a second list for "Ocaml Beginners" but its running on Yahoo and the membership confirmation takes a while ... So let me ask you, what is wrong with this code let rec fac n = if n > 1 then n * fac (n-1) else 1 ;; print_int fac(6);; No matter if I compile this with ocamlc or run the commands with ocaml, I always get the error: ///////////////////////////////////////////////////////////////// File "ifelse.ml", line 2, characters 0-9: This function is applied to too many arguments, maybe you forgot a `;' /////////////////////////////////////////////////////////////////// What is the problem here? Adding an additional ; doesn't help of course. thanks ben _______________________________________________ Caml-list mailing list.
