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.
