CCSID 65535 is the default object-level CCSID for message files and message queues.
If an object has a CCSID of 65535, no conversions occur when adding messages to that object or when receiving messages from that object. Use CCSID 65535 if you do not want CCSID processing to occur.
CCSID 65535 is also known as *HEX.
CCSID 65534 is the default object-level CCSID for job message queues, system reply lists, and the history log. If the CCSID of an object is 65534, each message in the object has its own CCSID. No conversion occurs when a message is added to the object. When a message is received, it is converted based on the CCSID stored with the message.
CCSID 65534 is also known as *MSG or *MSGD.
CCSID 65534 is the preferred setting for object-level CCSIDs. An object-level CCSID of 65534 requires fewer CCSID conversions. Fewer CCSID conversions of text result in better performance and improved data integrity.
