String split problem

[Former Member]

Hi,

I have got a strange problöem when splitting a string into lines of 255 characters.

I need to save a string, which contains source code, into lines of 255 characters to save it in the db.

I have done it like this:

DATA:   z_counter           TYPE i,
                z_length              TYPE i,
                z_content           TYPE string,
                z_line_content TYPE Z_LINE_CONTENT. (this has as domain TEXT255)
DO.
    z_counter = z_counter + 1.
    z_length = strlen( z_content ).
    IF z_length > 255.
      z_line_content = z_content.
      SHIFT z_content LEFT BY 255 PLACES.
    ELSE.
      z_line_content = z_content.
      SHIFT z_content LEFT BY z_length PLACES.
    ENDIF.
    IF z_content IS INITIAL.
      BREAK.
    ENDIF.
ENDDO.

Strangly one time, it doesn't copy all the 255 characters to z_line_content, when there is a space sign. It is then just copying the data to the space sign. Any ideas why this happens?

Do you have any suggestions how to save that code in a table instead? Or any better way to split it? I need to be sure, that it is saved to the database like it is, because when I read it in a string again afterwards, it needs to be exactly the same.

I have seen, that I now could also use STRING in tables, but this couldn't be used for table maintenance then. Should I go for that instead?

I'm happy for all answers,

Thank you!

Hello,

Use SHIFT z_content LEFT DELETING LEADING SPACE.

Hello Michael,

Please check this function module "G_SPLIT_LINE" , it is used to split string into exact 71 characters.Similarly you can create your Z function module for 255 characters. You need to do simple changes to existing FM. Then pass your string to this FM.

I still cannot understand your question clearly. I feel that you need to respect the "space" when extracting 255 characters. In this case you can use the function RKD_WORD_WRAP passing OUTPUTLEN. = 255.

If you need to get the 255 characters without respecting the space, then the below logic will do

 do 1000 times.
   concatenate lv_string sy-abcde  into lv_string.
 enddo.
  len = strlen( lv_string ).
 lv_offset_mx = 255.
 lv_offset_mn = 0.
 div = ceil( len / 255 ).
 do div times.
   clear wa.
   wa = lv_string+lv_offset_mn(lv_offset_mx).
   append wa to itab.
   lv_offset_mn = 255.
 enddo.

Hi,

just to inform you: I have changed the table field to a string field. I was trying around and still don't know  why I got this strange behaviour in some cases. The string field works fine for me.

Thank you & best regards,

Michael
