I'm trying to follow the code in "The Best FSM so far", and I can't see the moment where offset-to-action is added to the base address of the FSM like in the previous examples. Shouldn't there be a `R@ +` after `CELLS`?

Re: Finite State Machines in Forth (1995)
#32FSM is something I've always been curious about but I can't seem to find any good intro on. Does anyone have a good recommendations? I sort of don't want one tied to a specific language but rather one that helps me understand it from a conceptual level. Thanks!
I hope this book puts you on the right path, Brothers and Sisters. https://en.wikipedia.org/wiki/The_Gospel_of_the_Flying_Spagh...
Ramen!

#33Earlier quoted context omitted.
What do your friends do with it? It’s very high on my priority list for new languages to learn, and finding a job with it someday would be very interesting.
One set work with maintaining old software for a national bank and the other set work with software for a huge international company that are not IT focused but ended up with software and firmware that just been ticking along since forever. I'm not jealous and don't think I would bear working like that every day for months. Take a hard look and try to build software with Forth before you try to use it professionally.
There's a reasonable number of people out there who would be very interested in a disambiguation of scale, architecture, implementational wins/shortcomings, etc, about these two cases.
Codebase size? Entropic/organizational complexity? Word style? Environment (custom/standard)? Standard(s) used? Ease of debugging? Testing methodology used?
I most definitely am not literally asking for answers to this set of questions (considering the cases of a bank and an industry that presumably doesn't want to be known for its software) - I guess I'm just being exact in the gist of my curiosity :)
The only interesting illustrative example I can provide is that Mattel once used Forth for its toys (quoting previous times I mentioned this: https://news.ycombinator.com/item?id=21823216, https://news.ycombinator.com/item?id=17755287)
I don't know of any recent case studies.
