I *think* I'm doing this in pforth, for the simple reason that gforth, uh, isn't maintained anymore it seems, and so got dropped out of Debian Testing (which I have now)? I *think* I'd be *happier* using RetroForth, which is a "modern" Forth, but I guess it's better to learn the standardized, ANS Forth first. Even though everyone hates ANS Forth? Including the inventor of Forth…?
My biggest fear is there appears to be no way to read numbers written in ASCII from a file. We're predating ASCII
