Glad to help. The only bummer is that you cna't have variable width lookbacks (positive or negative) like `(?<=x) or (?<!x)` You can have variable width look forward assertions though `(?=x) or (?!x)` ar OK..... cheers tachyon s&&rsenoyhcatreve&&&s&n.+t&"$'$`$\"$\&"&ee&&y&srve&&d&&print	[reply] [d/l] [select]
