to initialise STRUCT RESOURCE members</title><prolog><metadata><keywords/></metadata></prolog><conbody>
<p><i><codeph>&lt;struct-initialiser&gt;</codeph></i>

<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><b>struct-initialiser-item ::=</b>
    </p>
<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>
