You may use "match" and "on error" but it sure will not be good enough for educational purposes then.

Your routine returns a wrong result for strings just one character long - a tough problem for cryptographic character frequency methods .

You may also consider turning the routine into a function and making it ORIGIN-aware.

Maybe also adding a custom error message if the argument is the nullstring.

So we are happily awaiting your language translation routine in Mathcad 😉
