in reply to RegExp quick question

I'm also not quite sure what you're going for here. If you have a word such as 'foo.bar', you'd probably just want to do something like
my($before, $after) = split(/\./, $word);
Or, if the word might contain multiple periods
my @tokens = split(/\./, $word);
If you need to check that there is a period in the word, you should use the if statement posted above before splitting. If you want to verify that a word contains only letters, you'd want to do a matching regular expression prior to the split
$word =~ /^[a-zA-Z]+\.[a-zA-Z]*$/;
And potentially throw in some /s* if you want to check for whitespace in it.
