@phloggen@expressional.social Way too rich for me! I have to make do with a 6½ digit 34410A, which I purchased new twenty years ago, back when I was still employable. I'll try it, but I expect it to just give an unrecognized command error. I put an XYZZY command into several of the products I've worked on that had command parsers. Without arguments, it just gave a stock answer, like "Nothing happens." With the right arguments, it did various things useful for a developer.
