Happy to see Ada still gets some interest outside of MIC. When I went off to university, I was a Perl snob but my school used Ada as its primary teaching language. It was a great way of expanding my knowledge across the horizon to understand the value in strong typing.

After nearly half a century, I still don't have ASCII memorized either but usually just use asciitable.com to do a quick lookup. Having a system utility like this one would be handy in situation without internet access. Plus like he noted, it was a good way to learn more about Ada.

Obligatory Perl snobbery: Perl wins the day by being shorter and better output and already installed on your computer.
