Example:

    int my_global = 10;
    void combined(int x)
    {
      int y, z;

      x ++;                // + 1 Parameters count
      if (x > 10)          //     Duplicates do not count
        x = 0;             //     Duplicates do not count

      y ++;                // + 1 Locals count
      if (y > 10)          //     Duplicates do not count
        y = 0;             //     Duplicates do not count

      my_global ++;        // + 1 Globals count
      if (my_global > 10)  //     Duplicates do not count
        my_global= 0;      //     Duplicates do not count
    }                      // CountObjectsUsedSetModifiedUnique = 3
