Hi
You can write what you want to dysplay your text. For example I created a document (type SIMG) by SO72 and this is the code to call it:
FORM MY_F1_FOR_S_CUST.
  DATA: T_LINE LIKE TLINE OCCURS 0,
        XHEAD  LIKE THEAD,
        HELP_INFO LIKE HELP_INFO,
        TEXC LIKE SY-UCOMM OCCURS 0,
        V_OBJECT LIKE  DOKHL-OBJECT.
Costants
  DATA: PREF_SIMG(4) VALUE 'SIMG',
        DOCID_HY LIKE DOKHL-ID VALUE 'HY'.
Object name
  CONCATENATE PREF_SIMG MY_OBJECT INTO V_OBJECT.
Get Text
  CALL FUNCTION 'DOCU_GET_FOR_F1HELP'
       EXPORTING
            ID       = DOCID_HY
            LANGU    = SY-LANGU
            OBJECT   = V_OBJECT
       IMPORTING
            HEAD     = XHEAD
       TABLES
            LINE     = T_LINE
       EXCEPTIONS
            RET_CODE = 1
            OTHERS   = 2.
  CASE SY-SUBRC .
    WHEN 0.
Dysplay text
      GET CURSOR FIELD HELP_INFO-DYNPROFLD.
      HELP_INFO-DOCUID         = DOCID_HY.
      HELP_INFO-DOCUOBJECT     = V_OBJECT.
      HELP_INFO-SPRAS          = SY-LANGU.
      HELP_INFO-PROGRAM        = SY-REPID.
      HELP_INFO-DYNPRO         = SY-DYNNR.
      HELP_INFO-DYNPPROG       = SY-REPID.
      HELP_INFO-PFKEY          = SY-PFKEY.
      HELP_INFO-FIELDNAME      = HELP_INFO-DYNPROFLD.
      CALL FUNCTION 'HELP_DOCULINES_SHOW'
           EXPORTING
                HELP_INFOS     = HELP_INFO
                OVERLAY_HEADER = XHEAD
           TABLES
                EXCLUDEFUN     = TEXC
                HELPLINES      = T_LINE.
    WHEN OTHERS. MESSAGE S720(SH).
  ENDCASE.
ENDFORM.
