Printing the hash values could be simplified thus:
my %hash = ( A => [1,2],
B => [4,6]);
while (my ($k,$v)=each %hash){
print qq ($k: @$v\n)
}
-- Output---
A: 1 2
B: 4 6
UPDATE:If you want it sorted, here is the code:
my %hash = ( S => [1,2], B => [4,6],);
print qq($_: @{$hash{$_}}\n) for sort keys %hash;
--output--(Notice, it IS sorted)--
B: 4 6
S: 1 2
