what's wrong with this procedure?

Here is my little simple procedure:

create or replace procedure main IS
begin

        dbms_output.put_line(to_char(sysdate, 'MM/DD/YY')); End;
/

And i stored it in 1.sql. I ran it
SQL>@1
and it gave me
Procedure created.

But there is no output at all.
Do I need to run it additionally?(if so, how?) Or there is something wrong with the procedure I wrote?

Thanks in advance.
