When to indicate a DBCS file

You should indicate that a file is DBCS in one or more of the following situations:

• The file receives input, or displays or prints output, which has double-byte characters.
• The file contains double-byte literals.
• The file has double-byte literals in the DDS that are used in the file at processing time (such as constant fields and error messages).
• The DDS of the file includes DBCS keywords. See the DDS Reference for information on these keywords.
• The file stores double-byte data (database files).
