You need double backslashes because two things are happening. Firstly, the regexp wants \< and \> for word boundary markers because that is needed to make < and > into special markers instead of literal characters. Figure out the regexp "raw" like this first. Thus: \<etch\> Secondly, you're putting that in a quoted string. Single slosh (\) is used in quoted strings to quote stuff (eg \" for a literal double quote), you need to write \\ for a literal slosh. And you want a literal slosh. Thus: "\\<etch\\>" Cheers, -- Cameron Simpson <c...@zip.com.au> DoD#743 http://www.cskk.ezoshosting.com/cs/ No man should escape our universities without knowing how little he knows. - J.
