Double-byte parser

Former Member

Hey,

I need to load in 400 character string of data into text using the FM SAVE_TEXT in chucks of 60 characters. If the user logs in Japanese, they could be loading in a mix of single byte and double characters. I need to be able to check if I break my string of data at the 60th character, will I be corrupting a double character.

Does anyone know how to perform this test in ABAP?

Thanks for the feedback! Bill

Hi Bill,

If you are on version 6.2+ you could try using the NUMOFCHAR( ) command.

I guess you could do something like:


* First determine the number of actual
* characters in 60th and 61st bytes.
w_num_of_chars = NUMOFCHAR( w_text+60(2) ).

* If there is only 1, then split on 59.
IF w_num_of_chars = 1.
  .
  .
  .
* Otherwise, we have two characters so we can split at 60.
ELSE.
  .
  .
  .
ENDIF.

I must admit I'm a complete novice when it comes to double byte languages and their handling, so that may just be complete gobbledegook.

Hope that helps.

Cheers,

Brad
