Sorry that's a typo...but using the correct equality operator still results in all surnames getting printed	[reply]

Sorry that's a typo...but using the correct equality operator still results in all surnames getting printed Are all the surnames "Gay"? Is this what you have? `my %names = ( abe => { lincoln => [ 'Cheddar', 'Cheddar', ], }, george => { washington => [ 'Gay', 'Gay', ], }, ); for my $key ( keys %names ) { for my $key2 ( keys $names{$key} ) { if ( $names{$key}{$key2}[0] eq 'Gay' ) { print "Last Name:" . $names{$key}{$key2}[1] . "\n"; } } } __END__ Last Name:Gay` [download] There is no lincoln/cheddar printed	[reply] [d/l]

… the correct equality operator … Did you notice that `==` is not the correct equality operator? Most strings numerically evaluate to zero, so `'apples' == 'pears'` [download] is true, while `'apples' eq 'pears'` [download] is false.	[reply] [d/l] [select]
