In the line

$report =~ tr/-_.//d;  # underscores, dashes, and periods

won't the . match any character and filter it out? Don't you need to escape it, or does it work differently with the tr as opposed to s?

There is no emoticon for what I'm feeling now.

No, tr/// is not s/// or m//, but it's y/// :-) The transliteration operator does not have anything to do with regular expressions, that's why the . doesn't have special meaning in it. See perlop. -- http://fruiture.de	[reply]
