Please be precise. What is the exact change you made? What is happening when you get that error? As far as I can see, that error message is from gengtype. Note that the type 'tree' is already a pointer; are you sure you want 'tree* abc' and not simply 'tree abc'? I would not be surprised if making that change fixes this problem. Ian
