I somehow can't install a working OCaml environment on my Windows computer. I want to use know the OCaml online compiler. Problem: I can only write one file there and put everything in that one file:
module Atom = struct
let hello name = print_string ( "Hello " ^ name );;
end
print_string "Hello, World!";
Atom.hello "Florian";
The above code produces the error:
Output:
File "./HelloWorld.ml", line 7, characters 0-12:
7 | print_string "Hello, World!";
^^^^^^^^^^^^
Error: Syntax error
Without the module Atom stuff, the print_string works! Is it not possible to define a module at the top of the file. Or where is the syntax error?
You are missing a ;;
at the end of the module declaration:
module Atom = struct
let hello name = print_string ( "Hello " ^ name )
end;;
print_string "Hello, World!";
Atom.hello "Florian"
