Combining data help!

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi there Monks!
I need to add the values from $listA to @listB, I am later sending @listB as json to another program. What is the best way of doing this? Here is a sample code to show what I am trying to do:

...
use Data::Dumper; 
...
my $listA;
$VAR1 = [
          {
            'ZIP' => '01111',
            'CITY' => 'New York, NY',
            'STREET_NAME_1' => 'CONNECTOR PARK',
            'STREET_NAME_2' => '100 MAINST'
          }
        ];

my @listB;
$VAR1 = {
          'account' => '73240',
          'name' => 'G Church CO'
        };
$VAR2 = {
          'account' => '73240',
          'name' => 'A Church CO'
        };
$VAR3 = {
          'account' => '73240',
          'name' => 'B Church CO'
        };
$VAR4 = {
          'account' => '73240',
          'name' => 'C Church CO'
        };
$VAR5 = {
          'account' => '73240',
          'name' => 'D Church CO'
        };
$VAR6 = {
          'account' => '73240',
          'name' => 'E Church CO'
        };

What do you mean by "the values from `$listA` to `@listB`"? Do you mean append them to the end of the list (push)? Do you mean insert those fields into the hash refs? See How do I post a question effectively?. In particular, showing code and desired output would be very helpful. Assuming you are trying to insert the key-value pairs in `$listA` into each element of `@listB`, using Foreach Loops seems pretty straight forward: `foreach my $acct (@listB) { %$acct = (%$acct, %{$listA->[0]}); }` [download] #11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.	[reply] [d/l] [select]

Sorry for the incosistency, but just need to add this block `{ 'ZIP' => '01111', 'CITY' => 'New York, NY', 'STREET_NAME_1' => 'CONNECTOR PARK', 'STREET_NAME_2' => '100 MAINST' } ]` [download] to the other variable.	[reply] [d/l]

Then my first guess of push is right: `push @listB, @$listA;`. Be aware that an array is not a valid root JSON object according the to literal spec.

What have you tried? CountZero A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout.

One way would be to use JSON.pm	[reply]

What about this: `push @listB, @$listA;` [download]	[reply] [d/l]

Of course! I just focused on the JSON creation - The array merge I thought the OP should figure out ...	[reply]
