Modifies information. Within the DESCRIPTION clause, this is
    information documenting the file element; within the AUDIT
    clause, it is a history list entry. Valid delimiters are /* */
    or double quotation marks (" ").

    You can use Japanese to document comments in the DESCRIPTION or
    AUDIT clause for a field. To do this, use the SET CHARACTER_SET
    command and set the character_set of the session to DEC_KANJI.
