Horizantal Tab in Barcode

Question

Hi All ,
If we need a horizantal tab in SAP , we use cl_abap_char_utilities=>HORIZONTAL_TAB.
What we should enter if we need to enter same value using keyboard.
The requirement is to insert horizantal tab between two values (manually entered in an excel ).
And this horizontal tab should get recognized by barcode reader as horizontal tab.
Thanks and Regards ,
Vivek

Dear Vivek,
   For putting TAB and NEWLINE in Barcode we can use Hexa Decimal. I am giving example , i am using ~ tiled sign for field seperation, this can be used as per required guide line.:
   CONCATENATE g_docno '~' exdat_c '~' blwbno '~' j_1iexchdr-exnum  '~' exdat_c '~' '\0x09' '\&' 
                             vbak-bstnk '~' poitem '~' barcodeqty '~' 'TO' '~' lips-aeskd '~' batchno '~' manufdate_c '`'
  INTO barcodetext.
Please Note that:
1. This Hexa decimal '\0x09' is used for TAB definition
2.  '\&' is used for new line feed, this is basically (Carriage Return + Newline) as per SAP Note 645158 - New bar code technology.
   On place of '\&' we can use these two code with togather '\0x0D' '\0x0A' which means we give instruction first do Carriage Return ('\0x0D') then feed the New line '\0x0A' .But intresting part is that UNIX based system understand '\0x0A' means (Carriage Return + Newline) where as window based system does not so we have to give to Hexa decimal like '\0x0D' '\0x0A' together.
I have seen This class cl_abap_char_utilities=>HORIZONTAL_TAB does not work properly nither for TAB nor For NEWLINE.
Hope this will help to many who got problem with BARCODE (NEWLINE and TAB)
