Or if you want to reveal every character in your string's ascii code, you can do this: printf "%vd \n", $string;

Thanks for that. I had no idea it existed.

And (IMO) even better is that is led me to just try: printf "%vx\n", $s;. And whaddayaknow. It worked!

I'll be making much use of that in future.

    You can even get a little fancier if you want:

    my $string = "\x15hello"; printf "%#*vx \n", " ", $string; --output:-- 0x15 0x68 0x65 0x6c 0x6c 0x6f

    And the printf() actually reveals every character's ord(), so it's not confined to ascii characters.
