concatenate problem

Former Member — Mon, 21 May 2007 18:08:10 GMT

Hi guys,

I am experiencing a weird behabour with the concatenate function.

I have a internal table with 4 lines, each line has a sentence, and I want pass the 4 lines to an unique string. Everything is working perfectly until the 232 character, from this point the string container doesn't allow more data. I try to see if any error occurs with the concatenate statement, but sy-subrc is always 0 (zero).

This is the code of the function:

FUNCTION zhr_pd_f_utility_tab_to_str.

*"----

""Interfase local

*" EXPORTING

*" REFERENCE(P_STRING) TYPE STRING

*" TABLES

*" P_IN_TAB STRUCTURE TLINE

*"----

CONSTANTS:

c_linebreak TYPE abap_cr_lf VALUE cl_abap_char_utilities=>cr_lf.

DATA: l_linebreak(2) TYPE c.

DATA: str_aux(1000) type c.

FIELD-SYMBOLS: <l_convert>,

<l_line> LIKE LINE OF p_in_tab.

CLEAR p_string.

clear result_tab.

clear str_aux.

LOOP AT p_in_tab ASSIGNING <l_line>.

IF sy-tabix > 1 AND " not first line

( <l_line>-tdformat = '/' OR " new line

<l_line>-tdformat = '*' ). " new paragraph

CONCATENATE str_aux c_linebreak <l_line>-tdline INTO str_aux.

ELSEIF sy-tabix EQ 1.

str_aux = <l_line>-tdline.

ELSE.

CONCATENATE str_aux <l_line>-tdline INTO str_aux

SEPARATED BY ' '.

if sy-subrc eq 4.

break-point.

endif.

ENDIF.

ENDLOOP.

p_string = str_aux.

ENDFUNCTION.

any help?

thanks in advance.

cheers.

What made you think that concatenation is not happening after 232 characters ? In debugging mode you may not see the content more than that..

did you try in debugging mode using offset like

str_aux+300(35) - to show string content from 300 th position to 335 th position..

is it blank/./ ?

Hi,

the weird behavour still continue...

now, I am count all the characters of the string, and all the characters of the table, so at the end of the loop, I can count the amount of characters, and if there is any difference, I can add the remaining text.

PROBLEM, when I count the characters, it counts characters that are not in the string. The string shows me until 255 characters (not 232 as I told before. 255 sounds like the maximun amount of numbrer that can be count with a byte), but 279 are counted!!!!

I discover that no more than 255 chars are permitted, therefore, i have changed the string variable for a char(1024) but the problem still continue.... it is driving me crazy!!!!

any help?

thanks.
