Re: Hash of a nArray and all that comes with it.

%entry = {$item_id=>\@data, $item_id=>\@data.....etc}

I hope that's not what you're doing, because that assigns a hash reference to a hash without dereferencing.

As long as I give an explicit value for $j's range, the output is fine. But I cannot figure out how to access the arraysize for $entry[$i]

my $len = scalar @{ $entry{$key}[$i]  }

gives you the length of the $i array stored at $key.

And I think you're missing the part of your code where you assign to @entry, I can't see how you'll get any output like this. @entry = @{ $entry{$key} } should fix it.

Perl 6 - the future is here, just unevenly distributed

This is how %entry is being populated in the foreach loop: `@update = ($id, $title, $foo, $bar, $baz); $entry{$file_num} = \@update;` [download]	[reply] [d/l]
