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.
