Re: getting [1,1] expecting: EOF no matter what

Hi there
I know I'm missing a | at the end of the file but that's not my problem,
evey grammar I have tried I awlays get
[1,1] expecting: EOF, if I move the first caracter of the example file
to the 3rd line I get
[3,1] expecting: EOF
the point is it always expects a EOF to start reading a token
thanks in advance
