<concept id="GUID-97C0A5B1-99AE-5F71-9092-A6976E54AEA7" xml:lang="en"><title>How

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>

<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>
