I think you mean ... in length2 list []

Hello,

I asked this question also on the beginners list but till now no respons.
I have this :

let length list =3D
=C2=A0 =C2=A0 let rec length2 list2 acc =3D
=C2=A0 =C2=A0 =C2=A0 =C2=A0 match list2 with
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0| [] -> acc
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0| x::xs -> length2 xs (acc + 1)=
=C2=A0 =C2=A0 in acc 0 list2 list ;;

But as soon as I copie it into the ocaml prompt I see a message that the ac= c in the part in acc 0 list2 list is unbound.
