And a version based on a dispatch table (which is definitely overkill in a simple situation like this):

use strict; use warnings; my @input_array = qw( N1 N2 N3 N6 N7 ); my @input_A = qw( N1 N3 N11 N11 N10 N16 ); my @input_B = qw( N3 N6 N2 N7 N16 N19 ); my %flags; $flags{$_} |= 1 for @input_array; $flags{$_} |= 2 for @input_A; $flags{$_} |= 4 for @input_B; my %primaryCCO; my %dispatch = ( 3 => sub { my $label = shift; print "$label: only 1 input is PI\n" + }, 5 => sub { my $label = shift; print "$label: this is a wire\n" }, 7 => sub { my $label = shift; $primaryCCO{$label} = [1,1]; print "$label: CCO = ( @{$primaryCCO{$label}} )\n"; }, ); exists $dispatch{ $flags{$_}} and $dispatch{ $flags{$_} }->($_) for ke +ys %flags;
