There are generally two approaches, one is to have the Grammar create  
an AST - abstract syntax tree - while parsing the source and walk  
that tree afterwards. The other one is called syntax directed  
translation if I'm not mistaken and means that you write actions into  
the grammar ( the {} blocks) that handle the input.
