+to initialise STRUCT RESOURCE members</title><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p><i><codeph>&lt;struct-initialiser&gt;</codeph></i>
+</p>
+<p><b>struct-initialiser ::=</b>
+    </p>
+<p><i><codeph>&lt;struct-name&gt;</codeph></i><b> {</b> <i><codeph>&lt;struct-initialiser-item-list&gt;</codeph></i> <b>}</b> <i><codeph>&lt;struct-initialiser-item&gt;</codeph></i>
+</p>
+<p><b>struct-initialiser-item ::=</b>

+<p><i><codeph>&lt;member-name&gt; = &lt;initialiser&gt; ;</codeph></i></p>
+<p>To initialise a member of <codeph>STRUCT</codeph> type, give the <varname>struct-name</varname> with
+which you wish to initialise it, and then specify each member of that struct
+which you wish to initialise.</p>
+<p>The <varname>member-name</varname>s listed must be members of the <varname>struct-name</varname> struct.
+Each <varname>initialise</varname> must be of a type compatible with the member
+it is initialising.</p>
+<p><b>Example</b> </p>
+<p>Given the previously defined struct types,</p>
+<codeblock id="GUID-B7A47237-F871-5A07-B97B-11034F7019D1" xml:space="preserve">STRUCT STRINGCOUNT
+ {
+ BUF message;
+ WORD num;
+ }</codeblock>
+<codeblock id="GUID-562D9436-F734-5E07-B452-08BD40F08959" xml:space="preserve">STRUCT SAMPLE
+ {
+ WORD anynumber;
+ STRUCT text; // should be a STRINGCOUNT 
+ }</codeblock>
+<p>the following example shows how to define the struct within a resource:</p>
+<codeblock id="GUID-425AD6B0-750B-56C2-8643-2726904C7DB7" xml:space="preserve">RESOURCE SAMPLE show_how
+ {
+ anynumber=10;
+ text=STRINGCOUNT
+  {
+  message="Hello"
+  num=5;
+  };
+ }</codeblock>
+<p><b>Type safety</b> </p>
+<p>The compiler does not enforce type safety. Any struct can be used to initialise
+a member declared to be of struct type. Usually, however, the designer of
+the struct will have intended only one or a limited number of structs ever
+be used to initialise a member. You should ensure that you initialise struct
+members with the intended struct type.</p>
