Re^2: Add value from one array element into another of same ID

 #Use of uninitialized value in length...
for my $d (grep ! length $_->{Name}, @data) {
 ...

and here:

  #Use of uninitialized value in length...
 push @new, $d if length $d->{Name} && ! exists $used{ $d->{Name} };

What version of Perl are you running? `length undef` should return undef without warnings since 5.012 (April 2010), if I remember correctly. `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l] [select]
