someone else is sure to call you out on defining this stuff at the
beginning of the program before i am able to hit send, but i figured
i'd add to the message - don't do this.

not sure i get this, you get the keys, check if they match and assign
the values, why not just use 'each' if you want to check both keys and
values?

how about elsif?

you said you want a third hash, but then assign them to an array?

so, lets do what you asked (i like hashes better anyway :) )
my %hash3, %nothash;
my $found = 0;
while( my( $ikey, $ival ) = each( %hash1 ) ) {
while( my( $jkey, $jval ) = each( %hash2 ) ) {
if( ( $ikey == $jkey ) and ( $ival == $ikey ) ) {
$hash3{ $ikey } = $ival;
$found = 1;
}
}
if( $found == 0 ) {
%nothash{ $ikey } = $ival;
$found = 0;
}
not sure if that is any quicker and i just typed it, so it should work, but...
