<h1 class="topictitle1">LIFO (Last-In First-Out) keyword for physical and logical files</h1>
<div><p>Use this file-level keyword to specify that records with duplicate
key values from the same physical file member are retrieved in a last-in first-out
(LIFO) order.</p>
<div class="section"><p>This keyword has no parameters.</p>
<p>LIFO is not allowed with
an FCFO, FIFO, UNIQUE, or REFACCPTH keyword.</p>
<p>If you do not specify first-changed
first-out (FCFO), first-in first-out (FIFO), LIFO, or UNIQUE, records with
duplicate key values are retrieved in FIFO, LIFO, or FCFO order,
but the order in which they are retrieved is not guaranteed.</p>
<p>At least
one key field must be specified in a file containing the LIFO keyword. The
LIFO keyword is not valid when you specify FILETYPE(*SRC) on the Create Physical
File (CRTPF) or Create Logical File (CRTLF) command.</p>
</div>
<div class="example"><h4 class="sectiontitle">Example</h4><p>The following example shows how to specify
the LIFO keyword for a physical file.</p>
