<h1 class="topictitle1">FORMAT (Format) keyword for physical and logical files</h1>
|
||
|
|
<div><p>Use this record-level keyword to specify that this record format
|
||
|
|
is to share the field specifications for a previously defined record format.
|
||
|
|
The name of the record format you are defining must be the name of the previously
|
||
|
|
defined record format.</p>
|
||
|
|
<div class="section"><div class="p">The format of the keyword is: <pre>FORMAT([library-name/]database-file-name)</pre>
|
||
|
|
</div>
|
||
|
|
<p>The
|
||
|
|
database-file-name parameter is required. It is the name of the physical or
|
||
|
|
logical file from which the previously defined record format is taken.</p>
|
||
|
|
<p>The
|
||
|
|
library-name is optional. If you do not specify the library-name, the library
|
||
|
|
list (*LIBL) in effect at file creation time is used.</p>
|
||
|
|
<p>If you specify
|
||
|
|
the FORMAT keyword, you cannot specify field specifications for this record
|
||
|
|
format. Specify key specifications and, if necessary, select/omit specifications
|
||
|
|
if you want them to be in effect for this file. (They can be the same as or
|
||
|
|
different from the previously defined record format.)</p>
|
||
|
|
<p>The FORMAT keyword
|
||
|
|
is not valid in join logical files and you cannot specify a join logical file
|
||
|
|
as the parameter value on the FORMAT keyword.</p>
|
||
|
|
<p>If the database file from
|
||
|
|
which you are using the record format is deleted, the record format remains
|
||
|
|
in existence as long as some file is using the record format. For example,
|
||
|
|
RECORD in FILE2 uses the FORMAT keyword to share the specifications of RECORD
|
||
|
|
in FILE1. Both files have been created. If FILE1 is deleted and
|
||
|
|
then re-created with different DDS, RECORD still exists in FILE2. It can be
|
||
|
|
referred to for the original record format by other files using the FORMAT
|
||
|
|
keyword.</p>
|
||
|
|
<p>You cannot specify a distributed data management (DDM) file
|
||
|
|
on this keyword.</p>
|
||
|
|
</div>
|
||
|
|
<div class="example"><h4 class="sectiontitle">Example</h4><p>The following example shows how to specify
|
||
|
|
the FORMAT keyword for a logical file.</p>
|
||
|
|
<pre>|...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8

A</pre>
|
||
|
|
<p>The record format for this logical file is the same as
|
||
|
|
the previously specified record format in file FILE1. The name of this record
|
||
|
|
format (RECORD) must be the same as the name of the record format in FILE1.</p>
