Who otherwise would expect new Date() + " " + new Date() to err? * Who otherwise would expect an offset from GMT of "0159"? * Which VBScript user would expect an error in ISO Week Number thrice per 28 normal years plus once per 400? >Are there any browsers that implement \w incorrectly (i.e., as anything >but [a-zA-Z0-9_])? Yes, IE 8 adds dotted I. It may well be that the two extra \b found by IE 8 in my test string are on each side of dotted I. One at least is .... both are. Tests in JS-valid, link above. The set recognised by \w should be checked using WSH CScript/WScript, hence the cross-post. Lines ending * are not for JScript. -- (c) John Stockton, nr London UK. ?@merlyn.demon.co.uk Turnpike v6.05 MIME. Web <URL:http://www.merlyn.demon.co.uk/> - FAQish topics, acronyms, & links.

I do this because usage >pattern results in the same regexp object being used over and over. Interesting. Thanks! In my casse the caching is not worth the trouble, but it's a good thought.
