In such examples, the convention is to include the entire contents of the buffer in question between two lines of dashes containing the buffer name. </p> <p>You can use the ‘<samp>@point{}</samp>’ command to show the location of point in the text in the buffer. (The symbol for point, of course, is not part of the text in the buffer; it indicates the place <em>between</em> two characters where point is located.) </p> <p>The <code>@point{}</code> command is displayed as ‘<samp>∗</samp>’, either a pointed star or (when that is not available) the ASCII sequence ‘<samp>-!-</samp>’. </p> <p>The following example shows the contents of buffer <samp>foo</samp> before and after evaluating a Lisp command to insert the word <code>changed</code>. </p> <div class="example"> <pre class="example">---------- Buffer: foo ---------- This is the ∗contents of foo. ---------- Buffer: foo ---------- </pre></div> <div class="example"> <pre class="example">(insert "changed ") ⇒ nil ---------- Buffer: foo ---------- This is the changed ∗contents of foo. ---------- Buffer: foo ---------- </pre></div> <p>In a Texinfo source file, the example is written like this: </p> <div class="example"> <pre class="example">@example ---------- Buffer: foo ---------- This is the @point{}contents of foo. ---------- Buffer: foo ---------- (insert "changed ") @result{} nil ---------- Buffer: foo ---------- This is the changed @point{}contents of foo. ---------- Buffer: foo ---------- @end example </pre></div> </div> </body> </html>
