Hi Ram. Data::Page isn't as useful as it could be as there are no methods to modify a Data::Page object. You simply set it up with new (<total_data>, <data_per_page>, <page_number>) and can then drag useful values from it about the current page. The nicest method is 'splice' which will return the correct slice of an array for the page. To change pages, however, you need to create a new object. Take a look below. HTH, Rob use strict; use warnings; use Data::Page; my @data = 'A' .. 'Z'; # Go to the third five-element page # my $data = new Data::Page (scalar @data, 5, 3); print map "$_\n", $data->splice([EMAIL PROTECTED]); print "--\n"; # Go to the 'next' (fourth) five-element page # $data = new Data::Page (scalar @data, 5, $data->next_page); print map "$_\n", $data->splice([EMAIL PROTECTED]); print "--\n"; # Go to the last page # $data = new Data::Page (scalar @data, 5, $data->last_page); print map "$_\n", $data->splice([EMAIL PROTECTED]); print "--\n"; **OUTPUT K L M N O -- P Q R S T -- Z -- -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
