What am I missing here? `+' is special in a regular expression. It means to repeat the preceding item one or more times. X+++ doesn't make sense, since you're asking to repeat X one or more times, repeated one or more times, repeated one or more times. Probably the simplest thing to do is to use the `index' function instead of a regex. Instead of: > if ($teststring =~ /$alteredsearcher/) { use > if (index($teststring, $alteredsearcher) >= 0) { The whole point of regexes is that they have these magical characters like + and * and . that do special things; if you don't want those special behaviors, and you just want to see if one string is in another, `index' is the function to use. **Majordomo list services provided by PANIX <URL:http://www.panix.com>** **To Unsubscribe, send "unsubscribe phl" to majordomo@lists.pm.org**
