Re: tokens without input match

[Martin Alexander Neumann]

Hi Anand,

Bison expects its input to come from a lexer, i.e. all inputs are valid
tokens of the language Bison parses. If a token cannot be "matched", the
input is invalid.

If you want to be able to skip any input that is not a valid token, you
have to skip it in the lexer.

Yours
Alex
