 <p>These commands allow you to define different sorts of variables in
 object-oriented programming languages.
 </p>
 <dl class="table">
 <dt id='index-defcv'><span><code class="code">@defcv <var class="var">category</var> <var class="var">class</var> <var class="var">name</var></code><a class="copiable-link" href='#index-defcv'> &para;</a></span></dt>
 <dd><p>The <code class="code">@defcv</code> command is the general definition command for
 variables associated with classes in object-oriented programming.  The
 <code class="code">@defcv</code> command is followed by three arguments: the category of
 thing being defined, the class to which it belongs, and its
 name.  For instance:
 </p>
 <div class="example">
 <div class="group"><pre class="example-preformatted">@defcv {Class Option} Window border-pattern
 &hellip;
 @end defcv
 </pre></div></div>

 <p>produces:
 </p><dl class="first-defcv">
 <dt class="defcv" id="index-border_002dpattern"><span>Class Option of Window: <strong class="strong">border-pattern</strong><a class="copiable-link" href='#index-border_002dpattern'> &para;</a></span></dt>
 <dd><p>&hellip;
 </p></dd></dl>

 <p><code class="code">@defcv</code> creates an entry in the index of variables.

 </dd>
 <dt id='index-deftypecv'><span><code class="code">@deftypecv <var class="var">category</var> <var class="var">class</var> <var class="var">data-type</var> <var class="var">name</var></code><a class="copiable-link" href='#index-deftypecv'> &para;</a></span></dt>
 <dd><p>The <code class="code">@deftypecv</code> command is the definition command for typed
 class variables in object-oriented programming.  It is analogous to
 <code class="code">@defcv</code> with the addition of the <var class="var">data-type</var> parameter to
 specify the type of the instance variable.  Ordinarily, the data type
 is a programming language construct that should be marked with
 <code class="code">@code</code>. For instance:
 </p>
 <div class="example">
 <div class="group"><pre class="example-preformatted">@deftypecv {Class Option} Window @code{int} border-pattern
 &hellip;
 @end deftypecv
 </pre></div></div>

 <dd><p>The <code class="code">@defivar</code> command is the definition command for instance
 variables in object-oriented programming.  <code class="code">@defivar</code> is
 equivalent to &lsquo;<samp class="samp">@defcv {Instance Variable} &hellip;</samp>&rsquo;.  For

 </p>
 <div class="example">
