I am getting this error

Error: Parse error: illegal begin of top_phrase

when I am try to enter a comment in the interpreter. Are comments not allowed in ocaml interpreter or am I doing something wrong?


Solution

  • I'd say you're entering nothing at all, which is a syntax error.

    # (* Hello *) ;;
    Error: Syntax error
    

    Try entering something after the comment:

    # (* Hello *) 3 ;;
    - : int = 3
