If the CCSID of the message file is 65535 or 65534, no conversion occurs on the message description when it is added to the file. The message description CCSID is set to the CCSID specified on the ADDMSGD or CHGMSGD command.
For example, a message file MYMSGF has a CCSID of 65534. The job that is running is in CCSID 00037. You enter an ADDMSGD command, as follows:
ADDMSGD MSG('MSG #1') MSGID(TST0001) MSGF(MYMSGF)
The message text, MSG #1, is not converted when added to the message file. The message text is tagged 00037 because the CCSID parameter was not coded on the ADDMSGD command and the default CCSID parameter is *JOB.
