<h1 class="topictitle1">REF (Reference) keyword—physical files only </h1>
|
||
|
|
<div><p>Use this file-level keyword to specify the name of the file from
|
||
|
|
which field descriptions are retrieved.</p>
|
||
|
|
<div class="section"><div class="p">The format of the keyword is: <pre>REF([library-name/]database-file-name [record-format-name])</pre>
|
||
|
|
</div>
|
||
|
|
<p>REF
|
||
|
|
supplies the field attributes from a previously defined record format. Specify
|
||
|
|
the file name once in the REF keyword instead of on several REFFLD keywords
|
||
|
|
if each field description refers to the same file. To refer to more than one
|
||
|
|
file, use the REFFLD keyword. You can specify the REF keyword only once.</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 library list (*LIBL) in effect at file creation
|
||
|
|
time is used. Specify a record-format-name as a parameter value for this keyword
|
||
|
|
if there is more than one record format. If you do not specify the record-format-name,
|
||
|
|
each record format is searched sequentially. The first occurrence of the field
|
||
|
|
name is used.</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 library-name
|
||
|
|
are the DDM file and library names on the source system. The record-format-name
|
||
|
|
is the record format name in the remote file on the target system.</p>
