My experience is that it's very easy for "non-standard" characters to be corrupted by changes in character set. If you want to be absolutely sure that your code contains the right characters - and goes on containing the right characters even when the code is
- saved as a file
- copied from Windows to Linux
- etc
then you may want to code in the arabic numerals as named constants. In PL/SQL you can then refer to the constants:
declare
  arabic_one constant NCHAR(1) := CHR(12345);
  arabic_two ....
beginand in SQL you can just use the CHR() function
(sorry, I can't quickly find the unicode value for arabic 1 - find a table for your database characterset...)
PS in a procedure you never need to SELECT FROM DUAL to do a DECODE. Just replace it with a CASE expression
  V_REQ := CASE P_REQUEST
                  WHEN 'M' THEN 'M'
                  WHEN 'T' THEN 'T'
                  ELSE 'D'
                  END;Regards Nigel
