I have a hash that's keyed with integers. The integers can be any ol thing, say for example:

hash{-10} = bar
hash{-1} = foo
hash{12} = baz

Now I want to change the keys of the hash to be sequential, starting at 0, so that I would have:

hash{0} = bar
hash{1} = foo
hash{2} = baz

[download]

I wrote this:

$counter=0;
foreach (sort keys(%hashone))
{
    $hashone{$counter} = $hashone{$_};
    delete $hashone{$_};
    $counter++;
}

[download]

but it does odd things, like tossing out memory addresses and stuff. (incidentally, it always messes $hash{0} = some memory address) I also realize that I will have problems if my original hash was something like:


hash{-10} = bar
hash{1} = foo
hash{20} = baz

Can this be done without swapping values with a temporary hash? Thanks!
