I need Hash of Hashes.... But here,s the rub. All these lines are CI records from a ServiceNow CMDB. So I screwed up thinking the application name was on the same line. The application name is only the CI ( CI10335478 ). Now I need to look up the name of the CI and all applications have a sys_class_name = "cmdb_ci_appl" Its just that I need a placeholder for Application Name because the line containing that may be 10000 lines or more down the data. But I need a place holder for application name until it comes along and we can populate it. This is because the ouput data need to look like this. 

Status,Name,Description,Members,Id,InboundUtilizationBandwidth,Outboun
+dUtilizationBandwidth,Appliances,CollectOnDirector
      ,app_name1,CI10335478,MemberIP1;MemberIP2;MemberIP6,,,,,
      ,app_name2,CI10334984,MemberIP4;MemberIP2,,,,,

So what I need is to buld out the following array. 

$VAR1 = {
    'CI10335478' => 'app_name1' =>
                     MemberIP 1,
                     MemberIP 2,
                     MemberIP 6
                   ],
    'CI10334984' => 'app_name2' =>
                     MemberIP 4,
                     MemberIP 2,
        };

our %application = ();

sub add_to_application_members {
    my ($app_ci, $member_ip, $value) = @_;
    $application{$app_ci{$member_ip}} = $value;
}

sub add_to_application_names {
    my ($member, $value) = @_;
    $application{$member} = $value;
}

if ( $data[$class_pos] eq "cmdb_ci_appl" ) {
  add_to_application_names( $data[$ci_pos] => $data[$name_pos] );
  print Dumper( %application ) ;
}

if ( $data[$application_pos] ne "" && $data[$ip_address_pos] ne "" ) {
  add_to_application_members( $data[$application_pos] => $data[$ip_add
+ress_pos] );
  print Dumper( %application ) ;
}

_DATA_
u_ci_id,sys_class_name,application,ip_address ,name
CI12345,cmdb_ci_appl  ,           ,           ,foobar1
CI56789,cmdb_ci_svr   ,CI12345    ,10.10.10.10, hostname1
