CLASS counter IMPLEMENTATION.
  METHOD set.
    count = set_value.
  ENDMETHOD.
  METHOD increment.
    ADD 1 TO count.
  ENDMETHOD.
  METHOD get.
    get_value = count.
  ENDMETHOD.

      cnt_3 TYPE REF TO counter,
      cnt_tab TYPE TABLE OF REF TO counter.
DATA number TYPE i.
START-OF-SELECTION.
  CREATE OBJECT: cnt_1,

  MOVE cnt_2 TO cnt_3.
  CLEAR cnt_2.
  cnt_3 = cnt_1.
  CLEAR cnt_3.
  APPEND cnt_1 TO cnt_tab.
  CREATE OBJECT: cnt_2,
                 cnt_3.
  APPEND: cnt_2 TO cnt_tab,
          cnt_3 TO cnt_tab.
  CALL METHOD cnt_1->set EXPORTING set_value = 1.
  CALL METHOD cnt_2->set EXPORTING set_value = 10.
  CALL METHOD cnt_3->set EXPORTING set_value = 100.
  DO 3 TIMES.
    CALL METHOD: cnt_1->increment,
