    {
      int y, z;
      x = 1;           //     Parameters do not count
      x = 2;           //     Parameters do not count
      y = 1;           //     Locals do not count
      y = 2;           //     Locals do not count
      my_global = 1;   // + 1 Globals count
      my_global = 2;   //     Duplicates do not count
    }                  // CountObjectsSetUnique = 1
