Hi friends,

Please provide me some sample program how to use "code page" statement in "READ OPENDATASET" command to create/modify the application server files.

Thanks & Regards,

Hi!

In general you can make something like the following(extend SAP-help):


data:
  begin of STRUC2,
    F1 type c,
    F2(20) type c,
  end of STRUC2.

* Put data into text format
move-corresponding STRUC to STRUC2.

* Write data to file
open dataset DSN in text mode for output encoding utf-8.
transfer STRUC2 to DSN.
close dataset DSN.

* Read data from file
clear STRUC.
open dataset DSN in text mode for input encoding utf-8.
read dataset DSN into STRUC2.
close dataset DSN.
move-corresponding STRUC2 to STRUC.
write: / STRUC-F1, STRUC-F2.

The textual storage in UTF-8 format ensures that the created files are platform-independent.

Case 2: Old non-Unicode format must be retained

 
* Write data to file
open dataset DSN in legacy text mode for output.
transfer STRUC to DSN.
close dataset DSN.

* read from file
clear STRUC.
open dataset DSN in legacy text mode for input.
read dataset DSN into STRUC.
close dataset DSN.
write: / STRUC-F1, STRUC-F2.

Using the LEGACY TEXT MODE ensures that the data is stored and read in the old non-Unicode format. In this mode, it is also possible to read or write non-character-type structures. However, be aware that data loss and conversion errors can occur in Unicode systems if there are characters in the structure that cannot be represented in the non-Unicode codepage.

Instead of legacy text mode you can define a specific codepage. Have a look in table TCP00 for available codepages in SAP.

Christian
