+example creates a doubly linked list of objects of the <codeph>TLetter</codeph> class.
+This list represents a character string. An object of class <codeph>CMyStringReverse</codeph> owns
+this string. The user can edit this string using the functions defined in
+the <codeph>CMyStringReverse</codeph> class. The following edit operations
+are possible: </p> <ul>
+<li id="GUID-D3B39123-1249-59DD-BC1F-2D62B7F9DE84"><p>Insert a character at
+the start of the list </p> </li>
+<li id="GUID-E6CEC00A-B6C1-53B2-9AAA-870EA8B06A5B"><p>Insert a character at
+the end of the list </p> </li>
+</ul> <p>The user can perform either of these operations by pressing keys
+specified in the menu. <codeph>CMyStringReverse</codeph> is an active object
+class and handles key press events in the <codeph>CMyStringReverse::RunL()</codeph> function.
+The <codeph>CMyStringReverse::ReadFunc()</codeph> function displays a menu
+and waits for an asynchronous key press event. </p> <p>The <codeph>CMyStringReverse</codeph> class
+has a doubly linked list iterator, <codeph>iIteratorString</codeph>. The <codeph>iIteratorString</codeph> object
+iterates through the list <codeph>iString</codeph> from start to end to print
+the string reversed. </p><p><b>Design and implementation</b></p><p>Figure
