what is s_gi() function in scriptlet?
<p>I am studying some source code, it's a web app using JSPs and Servlets.
Inside one scriptlet, there is some javascript code containing this function </p>

<pre><code>&lt;%
String callSCode = request.getSession().getAttribute("callSCode");
%&gt;
var s=s_gi('&lt;%=callSCode%&gt;');
</code></pre>

<p>what is <strong>s_gi</strong> doing?</p>
