I think he want array of integers to become key, not value	[reply]

ah, okay. Well, a reference to an array is a scalar. So, perhaps something like: `my @foo = qw/1 2 3 4 5 6/; my %bar = ( \@foo => 'elephants', ); my $zonk = \@foo; print "$bar{$zonk}\n";` [download] prints: `elephants` [download] Cheers, Darren :)	[reply] [d/l] [select]

I'm wondering why this is so difficult. If you take a string as the key to a hash, that string is actually an array of bytes, which is probably searched for by the C function strcmp. Now all I want is an array of which the elements are a tad larger (4 bytes iso 1 byte, because I need unsigned longs), and possibly another hash function (hashword in http://burtleburtle.net/bob/c/lookup3.c) and another comparison function similar to strcmp but working on integers.
