Hi,

What have you put in your math1.erl file?
Did you forget the full stop ('.') at the end of the program?

Here is the program from the tutorial:

-module(math1).
-export([factorial/1]).
factorial(0) -> 1;
factorial(N) -> N * factorial(N-1).

                                 ^^^
This compiles fine, but if you forget the full stop at the end, like this:

-module(math1).
-export([factorial/1]).
factorial(0) -> 1;
factorial(N) -> N * factorial(N-1)
                                 ^^^      
the compiler gives the "premature end" error.

Regards,

Dominic.
