Internal Table Manipulation

[Former Member]

Hi,

I have an internal tables with 5 fields each of type Char - L1 L2 L3 L4 L5.

I have to make the first occurance of 0 after a non zero value as 1.

Example: if i have the values as 1 0 0 0 0, it s'd be made 1 1 0 0 0.

If 1 1 0 0 0 it s'd be made 1 1 1 0 0.

If 0 1 0 0 0 then it should be made 0 1 1 0 0.

If i try this using nested IF statements the code becomes more complex.. Is there any other way out.. like using string operations??

Hi,

The following code will do:

field-symbols:

<field1>,

<field2>.

Loop at inttab

into line_of_inttab.

do 4 times.

assign component syst-index of structure line_of_inttab

to <field1>.

zzl_next_index = syst-index + 1.

assign component zzl_next_index of structure line_of_inttab

to <field2>.

if <field1> NE '0' and

<field2> EQ '0'.

<field2> = '1'.

exit.

endif.

enddo.

modify inttab

from line_of_inttab.

endloop.

Regards,

John.

Pradhiba,

You try the following code:

DATA: BEGIN OF tbl_table1 OCCURS 0,
        f1 TYPE n,
        f2 TYPE n,
        f3 TYPE n,
        f4 TYPE n,
        f5 TYPE n,
      END OF tbl_table1.

DATA: g_index LIKE sy-tabix,
      g_found TYPE c.

FIELD-SYMBOLS: <fs> TYPE n.

START-OF-SELECTION.

  CLEAR tbl_table1.
  tbl_table1-f2 = 1.
  APPEND tbl_table1.

  LOOP AT tbl_table1.
    CLEAR: g_index,
           g_found.

    DO.
      ADD 1 TO g_index.
      ASSIGN COMPONENT g_index OF STRUCTURE tbl_table1 TO <fs>.
      IF sy-subrc NE 0.
        EXIT.
      ENDIF.

* Was there a 1 in the previous field?
      IF g_found = 'X'.

* Yes! Previous field was a 1, now make current field a 1 clear the
* G_FOUND flag and CONTINUE to next field
        <fs> = 1.
        CLEAR g_found.
        CONTINUE.
      ENDIF.

* Current field is a 1, mark the G_FOUND flag!
      IF <fs> = 1.
        g_found = 'X'.
      ENDIF.
    ENDDO.

    MODIFY tbl_table1.
  ENDLOOP.

END-OF-SELECTION.

  LOOP AT tbl_table1.
    WRITE:/ tbl_table1-f1, tbl_table1-f2, tbl_table1-f3, tbl_table1-f4,
            tbl_table1-f5.
  ENDLOOP.

Hi Pradhiba ,

why did you reward me?

-i've nothing written

->but now , i think , i've a solution:

REPORT zforum46 .

DATA: BEGIN OF itab ,
f1, f2, f3, f4, f5,
END OF itab.
DATA pos_1 TYPE sy-fdpos.

itab = '01100'.

SEARCH itab FOR '10'."
MOVE sy-fdpos TO pos_1.
ADD 1 TO pos_1.

MOVE '1' TO itab+pos_1(1).
WRITE: / itab.

best regards Andreas
