As the author of that review, I suppose I'll comment. I'll improve that review at some later point.
I don't use Forth for anything. The language is generally tedious and difficult to program. I prefer APL, which has some similar characteristics, but without the drudgery.
Regardless, it's a very good book, and has influenced my programming. I mostly think back to a single passage, but it's a very important passage:
You often see such applications that don't check input until you press ``return,'' at which time the system responds with an error message such as ``invalid number.'' It's just as easy-probably easier-to check each key as it's typed and simply not allow non-numeric characters to appear.
