Thanks the very first one worked. I was just trying to understand how it was working. So when we do array of hash the each new indices of array will have new key and value that way we avoid overwriting of same key value right?	[reply]

You are correct. If you dump the data, you will see all of your data in an array of hashes. `use Data::Dumper; print Dumper(\@information);` [download] *Have a cookie and a very nice day!* Lady Aleena	[reply] [d/l]

It's a hash of arrays %info is a hash $info{lastnames} is an array reference To take a page out of Basic debugging checklist tutorial `use Data::Dump; dd { lastnames => [ qw/ ro sham bo / ] }; __END__ { lastnames => ["ro", "sham", "bo"] }` [download] Hmm, lets try that again `use Data::Dump; my %info; push @{ $info{lastnames} }, 'ro'; push @{ $info{lastnames} }, 'sham'; push @{ $info{lastnames} }, 'bo'; dd \%info; __END__ { lastnames => ["ro", "sham", "bo"] }` [download] Thats better. Last demo `use Data::Dump; my %info; $info{lastnames}[0] = 'ro'; $info{lastnames}[1] = 'sham'; $info{lastnames}[2] = 'bo'; dd \%info; __END__ { lastnames => ["ro", "sham", "bo"] }` [download] Any time you're wondering about something , write yourself a little program like these three :) hashofarrays.01.pl, hashofarrays.02.pl, hashofarrays.03.pl Does a hash of arrays make sense for your use case, maybe :) maybe @records is a better fit, I can't tell yet	[reply] [d/l] [select]
