You can save yourself a lot of effort in posting by putting "<code>" at the beginning of your perl code, and "</code>" at the end.

Your "check_same" sub is written to use just two array refs as args, but you are calling it with a long list of arrays (not refs to arrays). The two calls you have to check_same should look like this: 

print "\@D is not the same as \@E\n" unless check_same( \@D, \@E );
print "\@D is the same as \@F\n" if check_same( \@D, \@F );

Apart from that, you should probably make your sub definition simpler (skip the "(\@\@)" part), but check to make sure the args are refs to arrays: 
sub check_same {
    my ( $ref1, $ref2 ) = @_;
    die "Bad args passed to check_array\n"
        unless ( ref( $ref1 ) eq 'ARRAY' and ref( $ref2 ) eq 'ARRAY' )
+;

    return 0 if @$ref1 != @$ref2;
    for my $i ( 0 .. $#$ref1 ) {
        return 0 if $$ref1[$i] ne $$ref2[$i];
    }
    return 1;
}

You might also consider the "carp" or "croak" methods provided in Carp, instead of "die", to handle those kinds of error conditions in a subroutine.
