<p>The Get AID (QsnGetAID) API waits for an AID-generating key to be
pressed.</p>
<p>This command corresponds indirectly to the 5250 Read Input Fields command.
Because the control characters specified on the underlying command are both
X'00', this operation will cause the cursor to move to the insert cursor
position when the keyboard is unlocked.</p>
<br>
<h3>Authorities and Locks</h3>
<p>None</p>
<br>
<h3>Omissible Parameter Group</h3>
<dl>
<dt><strong>AID code</strong></dt>
<dd>OUTPUT; CHAR(1)
<p>The variable that contains the AID code when the QsnRtvReadAID API has
completed.</p>
</dd>
<dt><strong>Low-level environment handle</strong></dt>
<dd>INPUT; BINARY(4)
<p>The low-level environment that the operation applies to. If this parameter
is omitted or given with a value of zero, the default low-level environment is
used.</p>
</dd>
<dt><strong>Error code</strong></dt>
<dd>I/O; CHAR(*)
<p>The structure in which to return error information. For the format of the
structure, see <a href="../apiref/error.htm#hdrerrcod">Error Code Parameter</a>. If this
parameter is omitted, diagnostic and escape messages are issued to the
application.</p>
</dd>
</dl>
<br>
<h3>Returned Value</h3>
<dl>
<dt><strong>AID code</strong></dt>
<dd>OUTPUT; CHAR(1)
<p>This API returns the value for the AID code parameter, X'00' if a general
error occurs during processing.</p>
