In certain old pieces of lisp code you will encounter error warnings, when running in Emacs to the following effect:</p> <table bgcolor="#000000" border="1"><tr><td border="0"><font color="#FFFF00"><b>Warning: !! The file uses old-style backquotes !!<br /> This functionality has been obsolete for more than 10 years already<br /> and will be removed soon. See (elisp)Backquote in the manual.</b></td></tr></table>

To fix this, so that these errors are no longer reported, remove oldstyle backquotes from your lisp code and replace them with newstyle backquotes, in line with the following example:

<table class="muse-table" border="2" cellpadding="5">

<tbody> <tr> <td>*Oldstyle</em></td> <td>(` (foo (, bar) (,@ bing)))</td> </tr> <tr> <td>*Newstyle*</td> <td>`(foo ,bar ,@bing)</td> </tr> </tbody> </table> <!— Page published by Emacs Muse ends here —> </div> <i>To send me feedback about this page, use the below email.</i><br /> <b>&copy; sumoudou.org 2010</b><br /> <img style="border:0" alt="sumoudou.org" src="email.gif" width="129" height="10" /><br /> <a href="http://www.gnu.org/" style="text-decoration: none;"><img style="border:0" alt="GNU" src="powered-by-gnu.png" />]] <a href="http://www.gnu.org/software/emacs/emacs.html" style="text-decoration: none;"><img style="border:0" alt="GNU Emacs" src="made-with-emacs.png" />]] <a href="http://hcoop.net/" style="text-decoration: none;"><img style="border:0" alt="HCoop" src="hcoop-proud-member.png" />]] <a href="http://hcoop.net/" style="text-decoration: none;"><img style="border:0" alt="HCoop" src="hosted-by-hcoop.png" />]] <a href="http://mwolson.org/projects/EmacsMuse.html" style="text-decoration: none;"><img style="border:0" alt="Emacs Muse" src="made-with-muse.png" />]] <a href="http://mwolson.org/projects/EmacsMuse.html" style="text-decoration: none;"><img style="border:0" alt="Emacs Muse" src="powered-by-muse.png" />]] <br /> <a href="http://www.fsf.org/resources/formats/playogg" style="text-decoration: none;"><img style="border:0" alt="Ogg" src="play-ogg.png" />]] <a href="http://www.catb.org/hacker-emblem/" style="text-decoration: none;"><img style="border:0" alt="Glider" src="glider.png" />]] <a href="http://ubuntu.com/" style="text-decoration: none;"><img style="border:0" alt="Ubuntu" src="ubuntu.png" />]] <a href="http://validator.w3.org/check?uri=referer" style="text-decoration: none;"><img style="border:0" alt="Valid XHTML 1.0 Strict!" src="valid-xhtml10-blue.png" />]] <a href="http://jigsaw.w3.org/css-validator/check/referer" style="text-decoration: none;"><img style="border:0" alt="Valid CSS!" src="valid-css-blue.png" />]] <br />Last updated March 5, 2010
