    13 to initialise STRUCT RESOURCE members</title><prolog><metadata><keywords/></metadata></prolog><conbody>

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

    17     </p>

    18 <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>

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

    21     </p>

    22 <p><i><codeph>&lt;member-name&gt; = &lt;initialiser&gt; ;</codeph></i></p>

    23 <p>To initialise a member of <codeph>STRUCT</codeph> type, give the <varname>struct-name</varname> with

    24 which you wish to initialise it, and then specify each member of that struct

    25 which you wish to initialise.</p>

    26 <p>The <varname>member-name</varname>s listed must be members of the <varname>struct-name</varname> struct.

    27 Each <varname>initialise</varname> must be of a type compatible with the member

    28 it is initialising.</p>

    29 <p><b>Example</b> </p>

    30 <p>Given the previously defined struct types,</p>

    31 <codeblock id="GUID-B7A47237-F871-5A07-B97B-11034F7019D1" xml:space="preserve">STRUCT STRINGCOUNT

    32  {

    33  BUF message;

    34  WORD num;

    35  }</codeblock>

    36 <codeblock id="GUID-562D9436-F734-5E07-B452-08BD40F08959" xml:space="preserve">STRUCT SAMPLE

    37  {

    38  WORD anynumber;

    39  STRUCT text; // should be a STRINGCOUNT 

    40  }</codeblock>

    41 <p>the following example shows how to define the struct within a resource:</p>

    42 <codeblock id="GUID-425AD6B0-750B-56C2-8643-2726904C7DB7" xml:space="preserve">RESOURCE SAMPLE show_how

    43  {

    44  anynumber=10;

    45  text=STRINGCOUNT

    46   {

    47   message="Hello"

    48   num=5;

    49   };

    50  }</codeblock>

    51 <p><b>Type safety</b> </p>

    52 <p>The compiler does not enforce type safety. Any struct can be used to initialise

    53 a member declared to be of struct type. Usually, however, the designer of

    54 the struct will have intended only one or a limited number of structs ever

    55 be used to initialise a member. You should ensure that you initialise struct

    56 members with the intended struct type.</p>
