Just use {$a cmp $b} or {$b cmp $a} for alphabetical
and {$a <=> $b} or {$b <=> $a} for numerical order.

Generally when I get any not GNU-based Unix system in my hands, I start

under NT which AFAIK lacks such tools for command-line text processing

you an error. Check out which file is included in wich one, and try to
find a loop.

Try this:

splice @array, 2, 1;

Try:

You may have to add something like this:
use lib "/path/to/your/file";
before require.
<*> is used for file globbing (that's why it's insecure to require) and
<"xxx.pl";> will return '"xxx.pl&quo

No. Printing $href->{fou} will not create 'fou' entry in %$href.
Printing
$href->{fou}{bar} will create $href->{fou} but not $href->{fou}{bar},
$href->{fou} will be a reference to an empty hash.

$hash is a hash reference, right? Then try:
$hash->{$key} = $value;
