Trying to understand.

[Almusious]

I wrote this late at night, pretty sure it will work out, though my comments -may- be off a little, maybe someone can correct me on any wrong points. We're all here to learn.

%HoH = (
	'leather'	=>	{
					'head'	=>	147587,
					'chest'	=>	147588,
					'legs'	=>	147591,
				},
	'plate'		=>	{
					'head'	=>	147580,
					'chest'	=>	147581,
					'legs'	=>	147584,
				},
	'chain'		=>	{
					'head'	=>	147573,
					'chest'	=>	147547,
					'legs'	=>	147577,
				},
	'cloth'		=>	{
					'head'	=>	147566,
					'chest'	=>	147567,
					'legs'	=>	147570,
				},
);

sub EVENT_SAY 
{
	if ($text=~/hasharmorset/i)
	{

		# iterate the parent keys of hash %HoH one by one and put the current key being read into $parentkey

			# make reference of first level hash based on current parent key (i.e. $parentkey)
			# $childhashref now equals $HoH{plate}
