Here are some examples: </p> <div class="example"> <pre class="example">@acronym{ABC, A Bizarre @comma{}} @xref{Comma,, The @comma{} symbol} @mymac{One argument@comma{} containing a comma} </pre></div> <p>Although ‘<samp>@comma{}</samp>’ can be used nearly anywhere, there is no need for it anywhere except in this unusual case. </p> <p>(Incidentally, the name ‘<samp>@comma</samp>’ lacks the ‘<samp>char</samp>’ suffix used in its companion commands only for historical reasons. It didn’t seem important enough to define a synonym.) </p> </div> </body> </html>
