Read texts and notes with function module READ TEXT

The text is written to a simple internal table with type 'TLINE'. Often the goal is to store the content in a string.

The concatenation depends on the TDFORMAT:

  IF sy-subrc = 0 AND lines( text_lines ) > 0.
    LOOP AT text_lines ASSIGNING FIELD-SYMBOL(<text_line>).
      IF <text_line>-tdformat EQ '*' AND sy-tabix > 1.
       result = |{ result }{ cl_abap_char_utilities=>cr_lf }{ <text_line>-tdline }|.
      ELSEIF <text_line>-tdformat EQ '=' OR sy-tabix = 1.
       result = |{ rv_result }{ <text_line>-tdline }|.
      ELSE.
       result = |{ result } { <text_line>-tdline }|.
      ENDIF.
    ENDLOOP.
  ENDIF.
