<p>The <strong>QsyChangeValidationLstEntry()</strong> function changes an entry
|
||
|
|
in a validation list object. The data to be encrypted, the entry data values,
|
||
|
|
and some of the entry attributes may be changed.</p>
|
||
|
|
|
||
|
|
<p>To identify an entry to be changed, there must be an exact match in the
|
||
|
|
entry for the value that is specified in the <em>Entry_ID</em> parameter and
|
||
|
|
the length of the entry ID. For example, an entry ID value of "SMITH" with a
|
||
|
|
length of 5 would not allow you to change an entry where the entry ID is "SMITH" and the length is 7.</p>
|
||
|
|
|
||
|
|
<p>Conversions are not done on any data when entries are changed. The CCSID
|
||
|
|
values are stored as part of the record, to be available to the user of the
|
||
|
|
API, but are not used when the entry is changed.</p>
