qr// is sweet. Big patterns are slower than many small patterns.
UNTESTED CODE:

my @codes = qw/ CODE1 CODE2 CODE3 /;
my @regex = map { qr/$_/i } @codes;

while (my $inputline = <FILE>) {
    my $found = 0;
    foreach my $regex (@regex) {
        last if ($found) = $inputline =~ /($regex)/);
    }
    next unless $found;
    
    # logic goes here
}

Make sure you put the most common codes at the front of your @codes array for more speed, since you'll do less searching.
