Thanks for that explanation, Ken.

I was aware of what "print for..." does (though I didn't realise some of the finer points you've mentioned), but I asked because I thought your code also worked without the 'for'. I now notice that the output without the 'for' has no newline between the returned arguments, i.e.:
ABCDEFGHIJabcde
which I assume is because it's just printing the 2 arguments (like a list) together.

All that makes sense now though (I think), thanks.

Sorry I wasn't clearer with my last question.

No worries. And, yes, your assumption is correct. Alternatives might be `print join "\n", unzip('AaBbCcDdEeFGHIJ', 5);` [download] or the completely mad and hairy `{ local $" = "\n"; print "@{[unzip('AaBbCcDdEeFGHIJ', 5)]}"; }` [download] which, of course, you'd never consider doing, would you? :-) -- Ken	[reply] [d/l] [select]

Thanks Ken. Correct - I would not do that. I does my head in.	[reply]
