Warning message:

Code:
foreach (sort { $dHash{$b}{'VAL} <=> $dHash{$a}{'VAL'} } keys %dHash) {
How do I fix? Should my sort function be checking for variable
defined? What do I return on undefined?

perhaps
foreach (sort { $dHash{$b}{'VAL'} <=> $dHash{$a

Inside the loop I check if the value is defined, so I don't care where
in the order the undefined one shows up in. I don't want to delete
undefined ones or anything...

Give it an initialized value. Maybe like this?
sort { ($dHash{$b}{VAL} ||

Then you can either turn off the warnings for that section (not
advised), ignore

In that case just create a list of the keys with a defined VAL value
before you do the sort:
my @keys = grep defined $dHash{$_}{VAL}, keys %dHash;
foreach (sort { $dHash{$b}{VAL} <=> $dHash{$a}{VAL} } @keys) {
print $_, "\n";
}

This solution appeals to me. I'll use it. Tha
