<h1 class="topictitle1">REF (Reference) keyword for ICF files</h1>
|
||
|
|
<div><p>Use this file-level keyword to specify the name of a file from
|
||
|
|
which field descriptions are to be retrieved.</p>
|
||
|
|
<div class="section"><p>Use it when you want to duplicate descriptive information from
|
||
|
|
several fields in a previously defined record format. This keyword allows
|
||
|
|
you to code the file name once rather than on each field that refers to the
|
||
|
|
file as is required by the REFFLD keyword. To refer to more than one file,
|
||
|
|
use the REFFLD keyword. The REF keyword can be specified only once.</p>
|
||
|
|
<div class="p">The
|
||
|
|
format of the keyword is: <pre>REF([library-name/]database-file-name [record-format-name])</pre>
|
||
|
|
</div>
|
||
|
|
<p>If there is more than one record format in the reference
|
||
|
|
file, specify a record format name as a parameter value for this keyword to
|
||
|
|
tell the <span class="keyword">i5/OS™</span> operating
|
||
|
|
system which one to use unless the record formats should be searched sequentially.</p>
|
||
|
|
<p>The
|
||
|
|
database-file-name is a required parameter value for this keyword. The library-name
|
||
|
|
and the record-format-name are optional.</p>
|
||
|
|
<p>If
|
||
|
|
you do not specify the library-name, the current library list (*LIBL) at file
|
||
|
|
creation time is used. If the record-format-name is not specified, each format
|
||
|
|
is searched in order (as they are specified). The first occurrence of the
|
||
|
|
field is used. For more information, see the topic <a href="../dds/specref.htm">When to specify REF and REFFLD keywords for DDS files</a>.</p>
|
||
|
|
<p>You can specify a distributed data management (DDM) file
|
||
|
|
on this keyword. When using a DDM file, the database-file-name and the library-name
|
||
|
|
are the DDM file name and library name on the source system. The record-format-name
|
||
|
|
is the record format name in the remote file on the target system.</p>
