[antlr-interest] problem with ast

[maciej1205]

Hi,

I'm trying to build aa compiler for small language ( int type, bool 
type, for , while, ..)
ex.
 program 
var a : int;
var b : int;
var c : bool ;
begin
 if c then b=a+b;
end ;
endprog;

I've already build parser but without rules.

problem is, I can't build ast tree for defined variables.
my idea is to build tree :
int_type                 bool_type
   |                         |
   a----value                c-----value
   | 
   b----value
   
Can anybody help me with this ?
