You are correct when you asked about the other data set, since in reality the data is with much more data as in this small code sample, but just like your previous observation:

my $data =[

   { Ad1 => '20 SOUTH CENTRAL  #B3', status => 'Main',     City => 'NY
+', zCode => '0002', name => 'John D',     ID => '2222', state => 'TO'
+ },
   { Ad1 => '15 SOUTH CENTRAL  #B4', status => 'Property', City => 'NY
+', zCode => '0002', name => 'John V',     ID => '2222', state => 'TO'
+ },
   { Ad1 => '100 main St.',          status => 'Houses',   City => 'BO
+', zCode => '0007', name => 'Mary Due',   ID => '2222', state => 'TO'
+ },
   { Ad1 => '5540 Chelsea Avenue',   status => 'Cabin',    City => 'NE
+', zCode => '4562', name => 'Carly Simon',ID => '2222', state => 'TO'
+ },

   { Ad1 => '12th Street',           status => 'Main',     City => 'NM
+', zCode => '2334', name => 'Charles D',  ID => '1111', state => 'CA'
+ },
   { Ad1 => '44 Dell St',            status => 'Houses',   City => 'MA
+', zCode => '9857', name => 'Marie Doe',  ID => '1111', state => 'CA'
+ },
   { Ad1 => '33 Dust Road',          status => 'Property', City => 'ET
+', zCode => '3345', name => 'Chapim Thor',ID => '1111', state => 'CA'
+ },
   { Ad1 => '01 Charles St',         status => 'Cabin',    City => 'CA
+', zCode => '2334', name => 'Claud Odur', ID => '1111', state => 'CA'
+ },
   
   
  ];

Now the results are confused:

$VAR1 = [
          {
            'new_City' => 'MA', # Should be BO
            'ID' => '2222',
            'status' => 'Main',
            'name' => 'John D',
            'City' => 'NY',
            'new_aA1' => '44 Dell St', # Should be 100 main St.
            'state' => 'TO',
            'new_zCode' => '9857', # Should be 0007
            'Ad1' => '20 SOUTH CENTRAL  #B3',
            'new_name' => 'Marie Doe', # SHould be Mary Due
            'zCode' => '0002'
          },
 
          {
            'new_City' => 'MA',
            'ID' => '1111',
            'status' => 'Main',
            'name' => 'Charles D',
            'City' => 'NM',
            'new_aA1' => '44 Dell St',
            'state' => 'CA',
            'new_zCode' => '9857',
            'Ad1' => '12th Street',
            'new_name' => 'Marie Doe',
            'zCode' => '2334'
          },

        ];
