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

hey, I wanted to know how Set::Scalar can be used in the same way as hashes my question is how can we set the values to the key and also whenever I wanted to replace the values with the new value using this Set::Scalar how can I do that. 
 For example
      now I have a key num_row and the values are '12350','archive'
      now how can I assign these values to the same key using Set::Sca
+lar and how can I print those values. 
Can any one please give me an idea about this.
Thank you.

    Set::Scalar manages an unordered collection of values; it doesn't have anything corresponding to keys.

    The simplest answer to what you seem to want would be a hash of arrays: 

    my %data;

# create a key num_row with two values
@{$data{num_row}} = ( '12350', 'archive' );
# add another value
push @{$data{num_row}}, '613';

foreach my $key (keys %data) {
   print "Examining key $key\n";
   foreach my $val (@{$data{$key}}) {
       print "value: $val\n";
   }
}

print "num_row's 2nd value is $data{num_row}[1]\n";
