"Escape" meaning what, exactly? If you want to escape it for use in a URL have a look at URI::URL's `equery()` method. If you want to escape it for use in a regex, take a look at the `quotemeta()` function and the `\Q` and `\E` escapes. (Info in perldoc perlre.) If you want to escape it for use in HTML, use CGI.pm's `escapeHTML() method`... If you want something else, you'll need to be more specific. -sauoq "My two cents aren't worth a dime.";	[reply]

If you're talking about escaping characters that have special meaning inside a regex, what you're looking for is `\`. perlre perlretut If not P, what? Q maybe? "Sidney Morgenbesser"	[reply] [d/l]
