+<p>A resource file has the following structure:</p>
+<section id="GUID-727A33A2-4324-4834-88B2-0D461C2A1732"><title>Comments</title>
+<p>You can use either C (<parmname>/* */</parmname>) or C++ (<parmname>//</parmname>)

+<p>The first non-comment statement in a resource must be the <parmname>NAME</parmname> statement.

+<p>where <parmname>name</parmname> is a 4 letter ID that is unique in the

+<p>For more information on the <parmname>NAME</parmname> statement, see <xref href="jar:GUID-35228542-8C95-4849-A73F-2B4F082F0C44.jar!/sdk/doc_source/ToolsAndUtilities94/DevTools-ref/ResourceFileFormat/Tool_Ref_RSS-file-format-NAME.html#DevTools%2dref%2erss%2dname" format="application/java-archive">NAME statement</xref>. </p>

+<section id="GUID-F27B120A-3B53-4B8A-828C-302B95E6E520"><title>C++ pre-processor
+statements</title>
+<p>The resource compiler supports a set of pre-processor statements, including:</p>
+<ul>
+<li><p><parmname>#define</parmname></p></li>
+<li><p><parmname>#include</parmname></p></li>
+<li><p><parmname>#ifdef</parmname></p></li>
+<li><p><parmname>#ifndef</parmname></p></li>
+<li><p><parmname>#if</parmname></p></li>
+<li><p><parmname>#else</parmname></p></li>
+<li><p><parmname>#endif</parmname></p></li>
+</ul>
+<p>For more information on the supported pre-processor statements, see
+ <xref href="jar:GUID-35228542-8C95-4849-A73F-2B4F082F0C44.jar!/sdk/doc_source/ToolsAndUtilities94/DevTools-ref/ResourceFileFormat/Tool_Ref_RSS-file-format.preprocess.html#DevTools%2dref%2erss%2e3" format="application/java-archive">C++ pre-processor statements</xref>.</p>
+<p>Typically, resource files contain <parmname>#includes</parmname> statements
+for the following files:</p>
+<ul>
+<li><p><parmname>appinfo.rh</parmname></p></li>
+<li><p><parmname>avkon.rh</parmname></p></li>
+<li><p><parmname>avkon.rsg</parmname></p></li>
+<li><p><parmname>eikon.rh</parmname></p></li>
+</ul>
+<p>These files are delivered with the Symbian SDK, and are located
+under the <parmname>/Epoc32/include</parmname> folder. They contain the structure
+declarations for commonly used data structures in the Symbian platform.</p>
+<p>For more information, see the commented example file, <xref href="GUID-411ACFE6-0324-4330-ABCD-97A925759A3C.dita">Resource
+management example: HelloWorldBasic</xref>. </p>

+<section id="GUID-9D5B35E3-21F3-4E22-B03B-8C9E6E1027C9"><title>RESOURCE statements
+syntax</title>
+<p>The RESOURCE keyword is used to declare a resource in a resource file.
+The syntax is as follows:</p>
+<codeblock id="GUID-88C7579F-4917-488F-8834-0579A3150D85" xml:space="preserve">RESOURCE <STRUCT_NAME> | <resource_name> |
+{
+<resource-initialiser-list>
+}</codeblock>
+<p>where:</p>
+<ul>
+<li><p><parmname><STRUCT_NAME></parmname> is the name of a declared
+data structure in an included resource header file.</p><p><parmname><STRUCT_NAME></parmname> must
+be in upper case.</p></li>
+<li><p><parmname>resource_name</parmname> identifies the resource.</p>
+<p><parmname>resource_name</parmname> must be in lower case.</p></li>
+<li><p><parmname>resource-initialiser-list</parmname> contains the
+values the members of the structure should be initialised with when the default
+values should not be used</p></li>
+</ul>
+<p><parmname>RESOURCE</parmname> statements may include resources defined
+within other resource statements in the resource file. For example:</p>
+<codeblock id="GUID-7F4CC81B-A596-4341-ACF2-61FEF518A9FF" xml:space="preserve">RESOURCE EIK_APP_INFO
+{
+menubar = r_name;
+}</codeblock>
+<p>uses a resource declared in a later statement to define its menu bar.
+For more information on <parmname>EIK_APP_INFO</parmname>, see <xref href="jar:GUID-35228542-8C95-4849-A73F-2B4F082F0C44.jar!/sdk/doc_source/reference/reference-resource/uikon/EIK_APP_INFO.html#EIK_APP_INFO" format="application/java-archive">EIK_APP_INFO</xref>.</p>
+<p>Resource statements may also included nested resource structures. For
+example:</p>
+<codeblock id="GUID-4A787831-2658-4BC0-939A-1346C3C05FE4" xml:space="preserve">RESOURCE MENU_PANE r_name2
+{
+items =
+ {
+ MENU_TITLE
+ {
+ menu_pane = r_name3;
+ }
+ };
+}</codeblock>
+<p>For more information on the <parmname>MENU_PANE</parmname> resource
+see , <xref href="GUID-E849C798-07A0-47B3-BDBF-203325062FBD.dita">Menu
