i was modified your code and add a some code :
i use your initial code...

function POP (var T : Tumpukan) : integer;

 {*this function to check stack is empty or not*}
 function Empty(var T : Tumpukan): boolean;

 begin
   Empty := (T.Atas = 0)
 end;      

 begin
   if Empty(T) then
      POP := 0
   else
      begin
        POP := T.Isi[T.Atas];
        T.Atas := dec[T.Atas];
      end;
 end;

Ok. Hope this helps....
