<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>

|
<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>
