<h1 class="topictitle1">Input field default values</h1>
|
||
|
|
<div><p>You can use these methods to put default values into the input
|
||
|
|
fields of your display, which users can override with their own data.</p>
|
||
|
|
<ul><li>Getting information from program <p>Never hard code the values as a literal
|
||
|
|
if they are language or cultural-dependent values. Use values
|
||
|
|
you can get from the system-provided information, such as system or job date,
|
||
|
|
or get the values from a data object, such as a database file or data area
|
||
|
|
from outside of the program.</p>
|
||
|
|
</li>
|
||
|
|
<li>Using DDS keywords DFT (Default) or DFTVAL (Default Value) <p>Specify
|
||
|
|
the default input value directly on the DDS after the keyword. The DDS keyword
|
||
|
|
DFT is for input-only (I) fields. For output-only (O) or input-output (B)
|
||
|
|
fields, use the keyword DFTVAL.</p>
|
||
|
|
<p>For example:</p>
|
||
|
|
<pre>A field-name length type I line pos DFT('default ')
|
||
|
|
or
|
||
|
|
A field-name length type O/B line pos DFTVAL('default value ')</pre>
|
||
|
|
</li>
|
||
|
|
<li>Using DDS keyword MSGID (Message Identification) <p>Using the Message
|
||
|
|
Identification (MSGID) keyword allows you to retrieve the content of a specified
|
||
|
|
message description when the program is run and to put that value as a default
|
||
|
|
in your display file field. The field must be input-output capable (B) for
|
||
|
|
you to use this technique.</p>
|
||
|
|
<p>For example:</p>
|
||
|
|
<pre>A field-name length type B line pos MSGID(message-id [*libl/message-file)</pre>
|
||
|
|
<p>This allows you to use different message files for each national language
|
||
|
|
version by setting the library list accordingly when the program is run.</p>
