GrandFather is spot-on!
To steal a sheet from a talk I did many years ago:
use Data::Peek;
foreach my $b (qw{ i I s S l L j J n N v V q Q }) {
foreach my $e ("", "!", "<", ">") {
$e =~ m{[<>]} && $b =~ m/[cCnNvV]/ and next;
$e =~ m{[!]} && $b =~ m/[jJqQ]/ and next;
my $f = "$b$e";
print STDERR "$f\t";
DHexDump pack $f => 0x1234567;
}
}
