The copy command assumes that the input string for character, DBCS-open, DBCS-either, or DBCS-only fields are in the CCSID of the job in which the copy command is running. The input string is converted to the CCSID of the from-field.
If no conversion table is defined or an error occurs while converting the input string, a message is sent and the copy operation ends. If the copy command can correctly convert the value, it uses the converted value for record selection.
