Very large string to internal text table

Former Member — Mon, 14 Jul 2008 06:55:20 GMT

Hi,

I have a string that contains all the information read from a flat file and I want to put all that information in an internal table where each row is just 1024 char in order to contain a row of the original flat file.

In the string I can recognize the special character "carriage return" in order to separate identify each row but now my problem is that I don't know can I parse the string text.

Can you help me please?

Hi Marshal,

I think by declaring a internal table of type string will help you out.

hi marshal ,

do like this first read the internal table and replace the all occurencse of carriage return with '#' and split the string

at '#'.

constant : c_enter type c ,

c_hash type c value '#' ..

data:

BEGIN OF wa_text ,

text(1024) TYPE c,

END OF wa_text.

i_text LIKE STANDARD TABLE OF wa_text.

REPLACE ALL OCCURRENCES OF c_enter

IN wa_text WITH c_hash.

SPLIT wa_text AT c_hash INTO: str1 str2 str3,

TABLE i_text.

regards,

sandeep

No, I need the information in a type char internal table...

My problem is that I don't know how to parse the string to get something like that:


LOOP AT string INTO aux_string FOR EACH new_line.

 APPEND aux_string TO char_internal_table.

ENDLOOP.

Obviously you can't use loop at string... but I need some way to do something similar

Hi Marshal,

continuing the program of sandeep.


Constant:
  c_enter type c,
  c_hash type c value '#' .

Data:
  BEGIN OF wa_text ,
    text(1024) TYPE c,
  END OF wa_text.
  
  i_text LIKE STANDARD TABLE OF wa_text.

REPLACE ALL OCCURRENCES OF c_enter
IN wa_text WITH c_hash.

DO.
    SPLIT wa_text AT c_hash INTO: str1 str2.
    IF str2 NE SPACE.
      APPEND str1 To i_text.
      wa_text = str2.
      CLEAR str2.
    ELSE.
      EXIT.
  ENDIF.
ENDDO.

WHERE c_enter contains the value of Carriage Return, which I also don't know.

Best Regards,

Sunil.

Thanks Sunil Saini,

That should work!

The solution is right but is very slow process and if the file grows, the cost increases exponentially.
