A.11. Answer for Chapter 12A.11.1. Exercise (Section 12.12.1)The module Oogaboogoo/date.pm looks like this: package Oogaboogoo::date; use strict; use Exporter; our @ISA = qw(Exporter); our @EXPORT = qw(day mon); my @day = qw(ark dip wap sen pop sep kir); my @mon = qw(diz pod bod rod sip wax lin sen kun fiz nap dep); sub day { my $num = shift @_; die "$num is not a valid day number" unless $num >= 0 and $num <= 6; $day[$num]; } sub mon { my $num = shift @_; die "$num is not a valid month number" unless $num >= 0 and $num <= 11; $mon[$num]; } 1; The main program now looks like this: use strict; use Oogaboogoo::date qw(day mon); my($sec, $min, $hour, $mday, $mon, $year, $wday) = localtime; my $day_name = day($wday); my $mon_name = mon($mon); $year += 1900; print "Today is $day_name, $mon_name $mday, $year.\n"; Copyright © 2003 O'Reilly & Associates.
