Hey!!

Check out this link

Check out this sample code, they are actually two programs which are inter related. copy paste them and run in debugging mode.

APPEND r_passenger TO plane_list.

                        im_cargo     = 533.

APPEND r_cargo TO plane_list.

LOOP AT plane_list INTO r_plane.
  r_plane->display_attributes( ).
ENDLOOP.
