help!

[Joao Jr.]

Hi, I'm beginner in erlang.

I can't use module in erlang, always return message error like:



Erlang (BEAM) emulator version 5.0.1 [threads]

Eshell V5.0.1 (abort with ^G)

1> -module(demo).

** exited: {undef,[{shell_default,module,[demo]},

{shell,local_func,4},

{erl_eval,expr,3},

{erl_eval,exprs,4},

{shell,eval_loop,2}]} **

2>

What can I do?

Thanks, Joao Jr.
