<h1 class="topictitle1">REF (Reference) keyword in printer 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>The format of the keyword is:</p>
|
||
|
|
<pre>REF([library-name/]data-base-file-name [record-format-name])</pre>
|
||
|
|
<p>Use
|
||
|
|
REF when you want to duplicate descriptive information from one or more fields
|
||
|
|
in a previously defined record format. You can code the file name once on
|
||
|
|
the REF keyword rather than on the REFFLD keyword with each of the field descriptions
|
||
|
|
that reference the file.</p>
|
||
|
|
<p>If there is more than one record
|
||
|
|
format in the referenced file, specify a record format name as a parameter
|
||
|
|
value for this keyword to tell the <span class="keyword"><font color="Purple">i5/OS™</font></span> operating system which record format to use,
|
||
|
|
unless the formats should be searched sequentially.</p>
|
||
|
|
<p>The database-file-name
|
||
|
|
is required for this keyword. The record-format-name and the library-name
|
||
|
|
are optional.</p>
|
||
|
|
<p>If you do not specify the library-name,
|
||
|
|
the current library list at file creation time is used. If you do not specify
|
||
|
|
the record-format-name, each format is searched in order (as they are specified).
|
||
|
|
The first occurrence of the field name is used.</p>
|
||
|
|
<p>You can specify a distributed
|
||
|
|
data management (DDM) file on this keyword. 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 record-format-name is the record format name
|
||
|
|
in the remote file on the target system.</p>

||
