Thanks. I was just doing that from the book.
I put this in a factorial file:
-module(factorial).
-export([factorial/1]).
factorial(0) -> 1;
factorial(N) ->
N * factorial(N-1).
and then ran:
factorial(3).
and got an error then I remembered I had to do module_name:function(value)
this is an interesting language...
