<h1 class="topictitle1">REFFLD (Referenced Field) keyword in printer files</h1>
|
||
|
|
<div><p>Use this field-level keyword when referring to a field under one
|
||
|
|
of these three conditions in this topic.</p>
|
||
|
|
<div class="section"><ul><li>The name of the referenced field is different from the name in positions
|
||
|
|
19 through 28.</li>
|
||
|
|
<li>The name of the referenced field is the same as the name in positions
|
||
|
|
19 through 28, but the record format, file, or library of the referenced field
|
||
|
|
is different from that specified with the REF keyword.</li>
|
||
|
|
<li>The referenced field occurs in the same DDS source file as the referencing
|
||
|
|
field.</li>
|
||
|
|
</ul>
|
||
|
|
<p>The format of the keyword is:</p>
|
||
|
|
<pre>REFFLD([record-format-name/]referenced-field-name
|
||
|
|
[*SRC | [library-name/]data-base-file-name])</pre>
|
||
|
|
<p>The referenced-field-name
|
||
|
|
is required even if it is the same as the referencing field. Use the record-format-name
|
||
|
|
when the referenced file contains more than one record format. Use *SRC (rather
|
||
|
|
than the database-file-name) when the referenced field name is in the same
|
||
|
|
DDS source file as the referencing field. *SRC is the default value when the
|
||
|
|
database-file-name and the library-name are not specified.</p>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> When you
|
||
|
|
refer to a field in the same DDS source file, the field being referred to
|
||
|
|
must precede the field being defined.</div>
|
||
|
|
<p>Specify the database-file-name
|
||
|
|
(qualified by its library-name, if necessary) when you want to search a particular
|
||
|
|
database file.</p>
|
||
|
|
<p>If, in the same DDS source file, you specify REF at the
|
||
|
|
file level and REFFLD at the field level, the particular search sequence depends
|
||
|
|
on both the REF and REFFLD keywords.</p>
|
||
|
|
<p>You must specify an R in position
|
||
|
|
29. In some cases, some keywords specified with the field in the database
|
||
|
|
file are not included in the printer file.</p>
|
||
|
|
<p>You can specify a distributed
|
||
|
|
data management (DDM) file on this keyword.</p>
|
||
|
|
<p>When you use
|
||
|
|
a DDM file, the data-base-file-name and library-name are the DDM file and
|
||
|
|
library names on the source system. The referenced-field-name and the record-format-name
|
||
|
|
are the field name and the record format name in the remote file on the target
|
||
|
|
system.</p>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> IDDU files cannot be used as reference files.</div>
|
||
|
|
<p>Option
|
||
|
|
indicators are not valid for this keyword.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Example</h4><p>The following example shows how to specify
|

the REFFLD keyword.</p>

|
||
|
|
<p>Because the REF keyword is not specified, the default
|
||
|
|
for lines 00030 and 00040 is to search the DDS source file in which they are
|
||
|
|
specified. In line 00080, the parameter value *SRC explicitly specifies the
|
||
|
|
source file. See the example in <a href="../dds/specref.htm">When
|
||
|
|
to specify REF and REFFLD keywords for DDS files</a> for explanations of
|
||
|
|
the specifications.</p>
