<u>For READ mode:</u>

DATA FNAME(60) VALUE 'myfile'.

DATA: TEXT1(4) VALUE '1234 ',

TEXT2(8) VALUE '12345678',

TEXT3(2),

LENG TYPE I.

OPEN DATASET FNAME FOR OUTPUT IN TEXT MODE.

TRANSFER: TEXT1 TO FNAME,

TEXT2 TO FNAME.

CLOSE DATASET FNAME.

OPEN DATASET FNAME FOR INPUT IN TEXT MODE.

DO 2 TIMES.

READ DATASET FNAME INTO TEXT3 LENGTH LENG.

WRITE: / TEXT3, LENG.

ENDDO.

CLOSE DATASET FNAME.

The output appears as follows:

12 4

12 8

<u>And for WRITE mode:</u>

DATA FNAME(60) VALUE 'myfile'.

TYPES: BEGIN OF LINE,

COL1 TYPE I,

COL2 TYPE I,

END OF LINE.

TYPES ITAB TYPE LINE OCCURS 10.

DATA: LIN TYPE LINE,

TAB TYPE ITAB.

DO 5 TIMES.

LIN-COL1 = SY-INDEX.

LIN-COL2 = SY-INDEX ** 2.

APPEND LIN TO TAB.

ENDDO.

OPEN DATASET FNAME FOR OUTPUT.

LOOP AT TAB INTO LIN.

TRANSFER LIN TO FNAME.

ENDLOOP.

CLOSE DATASET FNAME.

OPEN DATASET FNAME FOR INPUT.

DO.

READ DATASET FNAME INTO LIN.

IF SY-SUBRC <> 0.

EXIT.

ENDIF.

WRITE: / LIN-COL1, LIN-COL2.

ENDDO.

CLOSE DATASET FNAME.

The output is:

1 1

2 4

3 9

4 16

5 25
