@unique_array[12..24] is an array slice. A slice is a subset of an array (or list or hash.) The statement above is equivalent to: $unique_array[ 12 ] = $first_total; $unique_array[ 13 ] = $second_total; $unique_array[ 14 ] = $third_total; $unique_array[ 15 ] = $fourth_total; $unique_array[ 16 ] = undef; $unique_array[ 17 ] = $fifth_total; $unique_array[ 18 ] = $sixth_total; $unique_array[ 19 ] = undef; $unique_array[ 20 ] = 1000; $unique_array[ 21 ] = undef; $unique_array[ 22 ] = undef; $unique_array[ 23 ] = undef; $unique_array[ 24 ] = undef; Slices are described in the perldata.pod document in the section "Slices". perldoc perldata John -- use Perl; program fulfillment -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
