CL Programming
Design your application programs for processing double-byte data in the
same way you design application programs for processing alphanumeric data,
with the following additional considerations:
- Identify double-byte data used in the database files, if any.
- Design display and printer formats that can be used with double-byte
data.
- If needed, provide double-byte conversion as a means of entering data for
interactive applications. Use the DDS keyword for double-byte
conversion (IGCCNV) to specify DBCS conversion in display files.
- Write double-byte error messages to be displayed by the program.
- Specify extension character processing so that the system prints and
displays all double-byte data.
- Determine which double-byte characters, if any, must be defined. ADTS/400: Character Generator Utility
describes how to define double-byte characters for DBCS-supported
countries.
