$_=$`.$_.$'.<>;split//;${/[@_[map{$i-($i="@-")%9+$_,9*$_+$i%9,9*$_%26+ +$i-$i%27+$i%9-$i%3}0..8]]/o||do$0}for/0/||print..9

Dear Monks, I need your help

I don't understand the "split" statement: no return value, apparently no side effect. Reading split was not helpful... :-/

Another thing: this solver works fine on debian but loop on win xp (strawberryperl 5.14.2.1)

UPDATE (solved):Thanks to BrowserUk, tobyink and eyepopslikeamosquito. Very clear and fast answers. FYI, in my case, difference between debian and winxp was in fact, between perl 5.8.8 and 5.14.2.1.

English is not my mother tongue.

    [Discipulus]: i will need to handle by reference later on
    [Eily]: kinda sounds like father Christmas is late
    [hippo]: (asking because I'm sure you said before about learning English) Did you know there are 2 different words for smaller quantities in English? They are "less" and "fewer". Fewer applies to a number of discrete things like days.
    Eily notes also
