<div class="section"> <p>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: </p>
|
||
|
|
<ul><li>Identify double-byte data used in the database files, if any.</li>
|
||
|
|
<li>Design display and printer formats that can be used with double-byte data.</li>
|
||
|
|
<li>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.</li>
|
||
|
|
<li>Write double-byte error messages to be displayed by the program.</li>
|
||
|
|
<li>Specify extension character processing so that the system prints and displays
|
||
|
|
all double-byte data.</li>
|

<li>Determine which double-byte characters, if any, must be defined.</li>
