When is the job default CCSID used for handling messages?

A job default CCSID is always a CCSID with an encoding scheme of 1100 (single-byte EBCDIC) or 1301 (mixed-byte EBCDIC).

The job default CCSID is used whenever both of the following conditions are true:

• A conversion occurs from a CCSID with an encoding scheme other than 1100 or 1301 to a job CCSID.
• The job CCSID is 65535.

For example, ASCII data must be converted to a CCSID associated with the data when asked to convert to the CCSID of a job. The job default CCSID is used because it is never CCSID 65535.
