You can implement something like this:

TYPES: ty_itab TYPE TABLE OF i WITH EMPTY KEY.
DATA(lt_entry_data) = VALUE ty_itab( ( 1 ) ( 2 ) ( 3 ) ( 4 ) ( 6 ) ( 9 ) (10) ).
DATA lt_result TYPE ty_itab.

lv_numbr = so_numbr-low.

WHILE lv_numbr <= so_numbr-high.
  READ lt_entry_data  WITH KEY table_line = lv_numbr TRANSPORTING NO FIELDS.
  IF sy-subrc <> 0.
    APPEND lv_numbr TO lt_result.
    WRITE: \ lv_numr.
  ENDIF.
  ADD 1 to lv_numbr.
ENDWHILE.
