    Using @names as before... 
    my %names_h = map { $_->[0] => 1 } @names;
#             map { @$_ } @names; # similar, but more scary

my $name = 'Jim';

print "Jim's in the hash\n"
  if $names_h{$name};

      Thank you all, I seem to be close...
      But if I go with grep as you suggest, I DO find the names, but how do I print the numbers as well? I tried with $_->1 but didn't work...

        Assuming you mean $_->[1] (wrapping code in <code>...</code> tags preserves things like []).

        It works for me! Perhaps you should show exactly what you tried and how exactly it "didn't work".
