Example: how to create a dynamic internal table

Code:
REPORT ZCLUST1 .
*
* Example: how to create a dynamic internal table
*
* The dynamic internal table stucture
DATA: BEGIN OF STRUCT OCCURS 10,
    FILDNAME(8) TYPE C,
    ABPTYPE TYPE C,
    LENGTH TYPE I,
END OF STRUCT.

* The dynamic program source table
DATA: BEGIN OF INCTABL OCCURS 10,
    LINE(72),
END OF INCTABL.

DATA: LNG TYPE I, TYPESRTING(6).

* Sample dynamic internal table stucture
STRUCT-FILDNAME = 'field1'. STRUCT-ABPTYPE = 'c'. STRUCT-LENGTH = '6'.
APPEND STRUCT. CLEAR STRUCT.
STRUCT-FILDNAME = 'field2'. STRUCT-ABPTYPE = 'd'.
APPEND STRUCT. CLEAR STRUCT.
STRUCT-FILDNAME = 'field3'. STRUCT-ABPTYPE = 'i'.
APPEND STRUCT. CLEAR STRUCT.

* Create the dynamic internal table definition in the dyn. program
INCTABL-LINE = 'program zdynpro.'. APPEND INCTABL.
INCTABL-LINE = 'data: begin of dyntab occurs 10,'. APPEND INCTABL.
LOOP AT STRUCT.
  INCTABL-LINE = STRUCT-FILDNAME.
  LNG = STRLEN( STRUCT-FILDNAME ).
  IF NOT STRUCT-LENGTH IS INITIAL .
    TYPESRTING(1) = '('.
    TYPESRTING+1 = STRUCT-LENGTH.
    TYPESRTING+5 = ')'.
    CONDENSE TYPESRTING NO-GAPS.
    INCTABL-LINE+LNG = TYPESRTING.
  ENDIF.
  INCTABL-LINE+15 = 'type '.
  INCTABL-LINE+21 = STRUCT-ABPTYPE.
  INCTABL-LINE+22 = ','.
  APPEND INCTABL.
ENDLOOP.
INCTABL-LINE = 'end of dyntab. '.
APPEND INCTABL.

* Create the code processes the dynamic internal table
INCTABL-LINE = ' '. APPEND INCTABL.
INCTABL-LINE = 'dyntab-field1 = ''aaaaaa''.'. APPEND INCTABL.
INCTABL-LINE = 'dyntab-field1 = ''19970814''.'. APPEND INCTABL.
INCTABL-LINE = 'dyntab-field1 = 1.'. APPEND INCTABL.
INCTABL-LINE = 'append dyntab.'. APPEND INCTABL.
INCTABL-LINE = ' '. APPEND INCTABL.
INCTABL-LINE = 'loop at dyntab.'. APPEND INCTABL.
INCTABL-LINE = 'write: / dyntab.'. APPEND INCTABL.
INCTABL-LINE = 'endloop.'. APPEND INCTABL.

* Create and run the dynamic program
INSERT REPORT 'zdynpro'(001) FROM INCTABL.
SUBMIT ZDYNPRO.
