Re: How do I loop over a reference to an array?

You can also use map as the looping mechanism...some may call it map abuse ;) Dereference in the usual fashion.

$arrayref = [0..10];
map {print "$_\n"} @$arrayref;

Map Abuse Map Abuse!! :) IMHO,a map in void context is a sign you should be using a for loop instead. `print qq{$_\n} for ( @$arrayref );` [download] Update: Oops, read rest of thread. Apologize for stating the obvious. :P Wonko.	[reply] [d/l]
