I would add `perldoc perldsc` And it happens that the free online chapter from merlyn's new book Learning Perl Objects, References and Modules covers this very topic. Check it out on the O'Reilly website. NB: that shouldn't stop you from buying the book :-) dave	[reply] [d/l]

An "array of arrays" is in fact an array of references to arrays. So each element of your @M is an array reference leading us to: `foreach $aref (@M) {...` [download] To get the actual array from an array reference, one usually writes `@$aref` leading us to `foreach $element (@$aref) {...` [download] and that's all about it.
