This is not really possible. OCaml-top sends its commands to the ocaml interpreter through the standard input, and read_int reads inputs on stdin also. This problem is tracked at https://github.com/OCamlPro/ocaml-top/issues/45
ocaml top: getting user's input
Domanda
Could you please show me how to get user's input in Ocaml-top?
It can be found in this link: http://www.typerex.org/ocaml-top.html
I'm a beginner in Ocaml and I'm trying to get the user's input to run this example
This is the code:
let rec hilo n =
let () = print_string "type a number: " in
let i = read_int ()
in
if i = n then
let () = print_string "BRAVO" in
let () = print_newline ()
in print_newline ()
else
let () =
if i < n then
let () = print_string "Higher"
in print_newline ()
else
let () = print_string "Lower"
in print_newline ()
in hilo n ;;
But the program stop at Type a number

Try to run it from command prompt. Type this command in the command prompt: ocaml filename.ml You can use it only if you have set the path in environment variables.
I have this working and the diff with the file above is zero
$ ocaml
starts the interpreter
# #directory "/home/wherever-your-OCaml-stuff-is";;
yes, type the extra # and the ;;
# #use "hilo.ml";;
no need to compile anything
# hilo 24356256456;;
it is not much of a guessing game...
