+<p>Functions which take a variable number of arguments, such as <codeph>TDes8::Format()</codeph>,
+always take the first parameter as a value reference.</p>
+<p>For example, the function <codeph>TDes8::Format()</codeph> is prototyped
+as:</p>
+<codeblock id="GUID-A3704F62-5577-585E-A6D5-052194467C7D" xml:space="preserve">void Format(TRefByValue&lt;const TDesC8&gt; aFmt,...);</codeblock>
+<p>The first argument is a value reference for a <codeph>const         TDesC8</codeph> type.
+Just pass a parameter of this type or a parameter that can be converted to
+that type. </p>
+<codeblock id="GUID-D4B86B9C-43B9-53A1-9038-A9515D6A806B" xml:space="preserve">_LIT(KFormat1,"%b %c %d %o %u %x");
