Hi,

I didn't understand following parts of your program:

1.

push @{ $data{ $cols[ 0 ] } }, pack 'C*', @cols[ 1 .. $#cols ];

2.

my $mask = $keyset1 ^ $keyset2; next unless 1+ index $mask, chr( 0 ); printf "%3d : %3d : ", $key1, $key2; print join ', ', map{ substr( $mask, $_, 1 ) eq chr(0) ? $_+1 : () } 0 .. length( $mask )-1;

I didn't understand the concept of map and $mask. When I trying to print the hash of arrays it is not giving me any numbers. Can you please help with it. Also, how can I use String::LCSS_XS on the hash of arrays (%data) to get the longest common substring between the various of rows apart from the ones having same id number.

Thanks.
