<h1 class="topictitle1">ALIAS (Alternative Name) keyword for display files</h1>
|
|
<div><p>Use this field-level keyword to specify an alternative name for
|
|
a field.</p>
|
|
<div class="section"><p>When the program is compiled, the alternative name is brought
|
|
into the program instead of the DDS field name. The high-level language compiler
|
|
in use determines if the ALIAS name is used. Read the appropriate high-level
|
|
language reference manual for information about ALIAS support for that language.</p>
|
|
<div class="p">The
|
|
format of the keyword is: <pre>ALIAS(alternative-name)</pre>
|
|
</div>
|
|
<p>The
|
|
alternative-name must be different from all other alternative names and from
|
|
all DDS field names in the record format. If a duplicate name is found, an
|
|
error appears on the field name or alternative name.</p>
|
|
<p>An alternative
|
|
name cannot be used within DDS or any other <span class="keyword">i5/OS™</span> function
|
|
(for example, as a key field name, as the field name specified for the REFFLD
|
|
keyword, or as a field name used in the Copy File (CPYF) command).</p>
|
|
<p>When
|
|
you refer to a field that has the ALIAS keyword, the ALIAS keyword is copied
|
|
in unless the ALIAS keyword is explicitly specified on the referencing field.</p>
|
|
<p>Option
|
|
indicators are not valid for this keyword.</p>
|
|
</div>
|
|
<div class="example"><h4 class="sectiontitle">Example</h4><p>The following example shows how to specify
|
|
the ALIAS keyword.</p>
