Re: i must have forgotten how split works...

Aaah - - - regexes in Perl can be both a Boon and a Bane!
You are splitting on "." - the regex for any character - - so all you are going to get back is what is between each character - - - nothing!
So split on "\."
You haven't forgotten how Split works - - just overlooked how regexes work! :)

So a split on "\." No... `"\."` is still `"."`. The constructed string should contain a backslash, so you have to write either `"\\."` or `'\.'` (or `'\\.'`). Constructing a regexp in a string is a bit of a pain. That's one of the reasons why `qr` was invented: `qr/\./` will do the right thing, and still return something that can be treated like a string. Safer still is to stop playing games and just use the regexp, and write `my ($pre, $suf) = split /\./, $DOMAIN;` [download]	[reply] [d/l] [select]
