Hi!

Well, the problem is that you do all your lexical analysis in the  
parser.
Lexer rules must be all-uppercase.
Simply changing all rules below the comment "Lexical analysis" to  
uppercase (and all the references, too)
at least makes it compile without a glitch.

There might be other problems with the grammar, but I cannot look  
into that right now, due to time issues :(

HTH,
