I just pasted your grammer into ANTLRWorks and it seemed happy. In the 
interpreter I entered the following:

a
b

With a real newline between them, it gave the correct output. See 
attached - if this list allows attachments, failing that I got:

<grammar Test>
      |
     prog
      |
     ---
    |   |
    a   b

Are you sure you used a real newline as opposed to the two characters "/n"?


Cheers,
Norm.
