Hi!

I hope this helps, this is what happens:

1: keys %Hash returns a list of all the keys in the hash
2: sort sorts that list
3: The foreach goes over the sorted list, presenting you the keys
of the hash in sorted order

foreach $key (sort{($a)<=>($b)} keys %hash)
[download]

is a perfectly valid way to get a list of the keys of the hash in
a sorted order (provided they are numeric)

btw the block that you mentioned does not operate on the hash
in any real sense, you use the keys of the hash in there
and yes, you can use those to access the hash.

GreetZ!,
