<h1 class="topictitle1">ZONE (Zone) keyword for physical and logical files</h1>
|
|
<div><p>Use this key field-level keyword to specify that only the zone
|
|
portion (farthest left 4 bits) of each byte of the key field is used when
|
|
constructing a value associated with this key field. The digit portion is
|
|
filled with zeros.</p>
|
|
<div class="section"><p>This keyword has no parameters.</p>
|
|
<p>This keyword is applied
|
|
against the entire key field (not just a position within the field) and is
|
|
valid only for character, hexadecimal, or zoned decimal type fields.</p>
|
|
<p>ZONE
|
|
is not allowed with the ABSVAL, SIGNED, or DIGIT keywords.</p>
|
|
<p>If you specify
|
|
ZONE for a key field, the value of the field is treated as a string of unsigned
|
|
binary data rather than signed (which is the default for zoned decimal fields).</p>

</div>

<div class="example"><h4 class="sectiontitle">Example</h4><p>The following example shows how to specify
|

the ZONE keyword.</p>
