Hi All, I have been trying to solve a problem which I have been having in the lexer, but with no luck. My example goes as follows. I have a simple grammar with two tokens. I want to treat the the string "$ text" as a token TEXTINPUT and everything else as a token ANYTHING, which matches anything. The scanning process works fine when you supply it the string "$ TEXT", the correct token is returned. And if any other character is supplied, the token ANYTHING is returned. However, for the string "$1", the scanner complaints that it was looking for ' ', and no viable alternative for 1. What I want it to return is two tokens ANYTHING for the "$", and another token ANYTHING for "1". I was reading into the concept of syntactic predicates to solve this issue, but I am not quiet getting it right. If anyone could point me in the right direction, it would be great. Also, I wanted to know if there are any other approaches to solve this issue. I got the syntactic predicates concept after reading the following article http://www.jguru.com/faq/view.jsp?EID=459059
