Hi, you may want to take a look at tr// (`translate'), especially the `s' modifier. This will replace multiple duplicated characters with one instance of the required character. For example, in your line $_=~s/ +/\t/s;, (the $_ isn't really necessary here) you could have tr/ /\t/s;. I understand it's quite a bit more efficient.
