<h1 class="topictitle1">ALIAS (Alternative Name) keyword for physical and logical files</h1>
<div><p>Use this field-level keyword to specify an alternative name for
a field. When the program is compiled, the alternative name is brought into
the program instead of the DDS field name.</p>
<div class="section"><p>The high-level language compiler in use determines if the ALIAS
name is used. See 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 is found, an error
message 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>
</div>
<div class="example"><h4 class="sectiontitle">Example</h4><p>The following example shows how to specify
the ALIAS keyword.</p>
<pre>|...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8
00010A FIELDA 25A ALIAS(CUSTOMERNAME)
A</pre>
<p>In the example, the alternative name for FIELDA is CUSTOMERNAME.</p>
