<h2>Low-Level Screen I/O Services APIs</h2>
|
||
|
|
|
||
|
|
<p>The low-level services are divided into the following functional groups:</p>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li><a href="dsm1a.htm">Screen Manipulation and Query APIs</a>, which are used
|
||
|
|
to query and manipulate the state of the screen.<br>
|
||
|
|
<br>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li><a href="dsm1b.htm">Buffer Manipulation and Query APIs</a>, which are used
|
||
|
|
to create, query, and manipulate input and command buffers used to interact
|
||
|
|
with the screen.<br>
|
||
|
|
<br>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li><a href="dsm1c.htm">Screen Input APIs</a>, which are used to read field
|
||
|
|
data and other information from the screen.<br>
|
||
|
|
<br>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li><a href="dsm1d.htm">Screen Output APIs</a>, which are used to define
|
||
|
|
fields and write data and other information to the screen.</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>The low-level screen I/O services APIs provide a direct interface to the
|
||
|
|
5250 data stream commands and user-defined data streams for performing basic
|
||
|
|
screen I/O operations. For detailed information about the results and
|
||
|
|
interactions of these operations, refer to the following 5250 data stream
|
||
|
|
documentation:</p>
