As Muthuvel pointed in his url:
Quote:
If status-key-1 is a nine (9) then status key 2 is "implementor-defined". Many vendors take advantage of the x"00' to x'FF' (or 0-255) binary value. Therefore, the file status key may not always be a numeric value.

Plus, I think it's a good idea to define numeric data as PIC X if no arith is planned for them. IMHO, A/N allows for greater flexibility and has better display properties.

Think of all the PIC 9 stuff you see every day: ssn's, phone#s, employee#s, etc.
