 <h1>TStatements</h1>
 <com:DocLink ClassPath="System.Web.UI.WebControls.TStatements" />
 
+<p>
+<tt>TStatements</tt> evaluates a sequence of PHP statements and displays the content rendered by the statements. To specify the PHP statements to be evaluated, set the <tt>Statements</tt> property. In a control template, <a href="?page=Configurations.Templates2#st">statement tags</a> are often used instead of the complete <a href="?page=Configurations.Templates1#ct">component tags</a> when the main purpose is to display the result rendered by some PHP statements. For example, the following two tags are equivalent,
+</p>
+<com:TTextHighlighter Language="prado" CssClass="source">
+&lt;com:TStatements&gt;
+  &lt;prop:Expression&gt;
+  setlocale(LC_ALL, 'nl_NL');
+  echo strftime("%A %e %B %Y",time());
+  &lt;/prop:Expression&gt;
+&lt;/com:TStatements&gt;
+
+&lt;%%
+  setlocale(LC_ALL, 'nl_NL');
+  echo strftime("%A %e %B %Y",time());
+%&gt;
+</com:TTextHighlighter>
+
+<p>
+<tt>TStatements</tt> evaluates the PHP statements during the rendering control lifecycle. Unlike <tt>TExpression</tt>, <tt>TStatements</tt> only displays the content 'echoed' within the statements.
+</p>
+
+<p>
+The context of the statements in a <tt>TStatements</tt> control is the control itself. That is, <tt>$this</tt> represents the control object if it is present in the statements. For example, the following statement tag will display the title of the page containing the <tt>TStatements</tt> control.
+</p>
+<com:TTextHighlighter Language="prado" CssClass="source">
+&lt;%%
+  $page=$this->Page;
+  echo $page->Title;
+%&gt;
+</com:TTextHighlighter>
+
+<p>
+Be aware, since <tt>TStatements</tt> allows execution of arbitrary PHP code, in general you should not use it to evaluate PHP code submitted by your application users.
+</p>
