<h1 class="topictitle1">Describe field use for logical files: Neither</h1>
|
||
|
|
<div><p>A neither field is used neither for input nor for output. A neither
|
||
|
|
field is valid only for join logical files. It can be used as a join field
|
||
|
|
in a join logical file, but your program cannot read or update a neither field.</p>
|
||
|
|
<p>Use neither fields when the attributes of join fields in the physical files
|
||
|
|
do not match. In this case, one or both join fields must be defined
|
||
|
|
again. However, you cannot include these redefined fields in the record format
|
||
|
|
(the application program does not see the redefined fields.) Therefore, redefined
|
||
|
|
join fields can be coded N so that they do not appear in the record format.</p>
|
||
|
|
<p>A field with N in position 38 does
|
||
|
|
not appear in the buffer used by your program. However, the field description
|
||
|
|
is displayed with the Display File Field Description (DSPFFD) command. </p>
|
||
|
|
<p>Neither fields cannot be used as select/omit or key fields.</p>
