<div><p><span>Use this field-level keyword when referring
|
||
|
|
to a field under one of the several conditions.</span></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>
|
||
|
|
<div class="p">The format of the keyword is: <pre>REFFLD([record-format-name/]referenced-field-name [ {*SRC |
|
||
|
|
[library-name/]database-file-name}])</pre>
|
||
|
|
</div>
|
||
|
|
<div class="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, the library-name, and the REF keyword are not specified.
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> When you refer to a field in the same DDS source file, the field you
|
||
|
|
are referring to must precede the field you are defining.</div>
|
||
|
|
</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. For more information, see the topic <a href="../dds/specref.htm">When to specify REF and REFFLD keywords
|
||
|
|
for DDS files</a>.</p>
|
||
|
|
<p>The letter R must be specified in position 29.
|
||
|
|
In some cases, if you specify a value for length, some keywords specified
|
||
|
|
with the field in the database file are not included in the ICF file. For
|
||
|
|
more information, see <a href="ref290.htm#ref290">Reference for ICF files (position 29)</a>.</p>
|
||
|
|
<p>You
|
||
|
|
can specify a distributed data management (DDM) file on this keyword.</p>
|
||
|
|
<p>When
|
||
|
|
using a DDM file, the database-file-name and the library-name are the DDM
|
||
|
|
file and library name 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> Interactive

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.</p>
