How to activate ocaml trace

[mdasraf...@gmail.com]

I am using Objective Caml version 3.12.1 in ubuntu. I could not trace my code. When I trace by code its gives a error "Error: Unbound value trace".

Could anybody help me to activate trace in my ocaml.

Hi !

Maybe you've forgotten the sharp character before your trace invocation ?

# let rec f n = if n = 0 then 1 else f (n - 1) * n;;
val f : int -> int = <fun>
# #trace f;;
f is now traced.
# f 3;;
f <-- 3                                                                                                                                                     
f <-- 2                                                                                                                                                     
f <-- 1                                                                                                                                                      
f <-- 0
f --> 1
f --> 1
f --> 2
f --> 6
- : int = 6

cheers,
