<p>The Get Short Form with Maximal CS for Specified ES and CP (QTQSMXC2) API
|
|
gets the CCSID with the maximal character set (CS) for a given code page (CP)
|
|
value. The encoding scheme (ES) parameter can be specified to distinguish
|
|
between usage of the same CP with two different encoding schemes, such as PC
|
|
Display compared to PC Data.</p>
|
|
|
|
<p>The CS element that is associated with the returned CCSID is the largest in
|
|
size of all the character sets that are contained in the associated code page
|
|
for that CS element in the CCSID resource installed on the system.</p>
|
|
|
|
<p>The QTQSMXC2 API acts as an extension of the functions of the CDRSMXC API in
|
|
that you can specify more code pages. The additional code pages are as
|
|
follows:</p>
|
|
|
|
<ul>
|
|
<li>932</li>
|
|
|
|
<li>934</li>
|
|
|
|
<li>936</li>
|
|
|
|
<li>938</li>
|
|
|
|
<li>942</li>
|
|
|
|
<li>944</li>
|
|
|
|
<li>946</li>
|
|
|
|
<li>948</li>
|
|
|
|
<li>949</li>
|
|
|
|
<li>950</li>
|
|
|
|
<li>1381</li>
|
|
</ul>
|
|
|
|
<p><strong>Note:</strong> Not all the registered code pages are full, leaving
|
|
room for possible future additions. The term maximal is used to distinguish it
|
|
from a full code page. Over time, when new larger character sets are registered
|
|
for a code page (this can happen until the code page is full), the maximal
|
|
character set also changes, leading to a new CCSID returned by this
|
|
function.</p>

32-bit two's complement binary values (12 bytes or 96 bits). The status code is

a non-negative number in the first 16 bits, and the reason code is a

of the status code and associated reason code values (in hexadecimal) contained

<h3>Usage Notes</h3>
|
|
|
|
<ol>
|
|
<li>Often it is required to find the CCSID when the ES, CS, and CP values are
|
|
known. CS and CP (also known as CGCSGID or GCID) are used in many existing IBM
|
|
architectures, data streams, and supporting products. Together with the CDRSCSP
|
|
API, this function aids in the coexistence and migration for products that have
|
|
to deal with the short form (CCSID) of identification on one side and the
|
|
intermediate form (the code page global identifier) on the other. Because the
|
|
intermediate forms are, by themselves, incomplete when used in some encoding
|
|
schemes, the function can return only a default value as defined in the
|
|
installation's resources, when the ESIN information is unknown.<br>
|
|
<br>
|
|
</li>
|
|
|
|
<li>When an ESIN value of zero is specified, the feedback code is never
|
|
returned as zero. Absence of an error results in a 0001 0003 feedback
|
|
code.</li>
|
|
</ol>
