<div><p>Either a program-described file or an externally described file
|
|
can be defined with the record format descriptions stored in
|
|
the data dictionary.</p>
|
|
<p>You can describe the record format information using interactive data definition
|
|
utility (IDDU). Even though the file is program-described, <span class="keyword">IBM<sup>®</sup> Query for iSeries™</span>, iSeries Access,
|
|
and data file utility (DFU) will use the record format description stored
|
|
in the data dictionary.</p>
|
|
<p>You can use IDDU to describe a file, then create the file using IDDU. The
|
|
file created is an externally described file. You can also move into the data
|
|
dictionary the file description stored in an externally described file. The
|
|
system always ensures that the definitions in the data dictionary and the
|
|
description stored in the externally described file are identical.</p>
