Here is the equivalent code, done using OO:
use warnings; use strict; my $host = ""; my (@T1_list, $current_T1); my @check = grep { chomp $_; $_ } <DATA>; for (@check) { if (m{([0-9]/[0-9]/[0-9])$}) { push @T1_list, $current_T1 = T1->new (INTERFACE=>$1) } elsif (m{pri-group}) { $current_T1->isPRI (1); } } if ( @T1_list ) { print "T1 Controller Summary:\n\n"; print scalar(@T1_list) . " total T1 interfaces\n"; $_->PrintName for @T1_list; print scalar(grep $_->isPRI(), @T1_list) ." total voice PRI(s)\n"; $_->PrintName for (grep $_->isPRI(), @T1_list); } else { print "No T1 interfaces found"; } { package T1; sub new{ my ($class, %att) = @_; return bless ( {PRI=>0, INTERFACE=>'', %att}, $class); } sub isPRI{ my ($self, $val) = @_; defined $val or return $self->{PRI}; $self->{PRI} = $val; } sub PrintName{ print $_[0]->{INTERFACE}, "\n"; } 1; } # End of T1
