Hi, I am using the following code block to produce the datastructure shown as output. 


open (NEW , "< /text.txt");
while(<NEW>){
    @val=split /\t/;
    $Tech_fy_reldata{$val[$npo]}{$val[$fy_closed]}[0] = '0';
}

________OUTPUT_______

$VAR5 = 'Data';
$VAR6 = {
          '2007' => [
                      '0'
                    ]
        };
$VAR7 = 'DataBase';
$VAR8 = {
          '2005' => [
                      '0'
                    ],
          '' => [
                  '0'
                ],
          '2007' => [
                      '0'
                    ],
          '2004' => [
                      '0'
                    ],
          '2006' => [
                      '0'
                    ]
        };

My requirment is instead of using a predefined HoH ($Tech_fy_reldata{$val[$npo]}{$val[$fy_closed]}[0] = '0';) , I need to create the same kind of output for more no of key is more levels of hash dynamicaly.

For ex, instead of $npo,$fy_closed there may be any variables and more than two or even one.
Values $npo,$fy_closed are stored in an array.So based upon the no of elements in the array my hash tobe builded.

Basically i am using this structure to group the line in a text file(somthing like group by clause in sql)

Is there any otherway to accomplish this task? Please help me. Thanks
