I am into it. And he has some more info. Just not here or there.
For batch mode you can run script. Using format print :-). But in real life when you encounter problem the great thing of lisp is you can curl-c and inspect what is going on. I just doing my study of cl-6502 and found that this interactive nature and the readable of lisp is invaluable.
For interactive mode you can do rely upon emacs (or ccl which I cannot use for look like a decade now due to sudden issue; finally resolve this using xaddr) or vim (google vim lisp lead you there) where you can load an image and then interactive with it.
Why it stop here in my script? Just inspect around.
Now this is somewhere possibly this article in the interactive mode to see how symbols, … etc might be useful. The problem I have (I just read it the third times trying my best to appreciate) is that it does not lead you to anywhere. If you do not know these the article does not help. If you do, it does not help much as it is not going deep enough.
Perhaps an interactive session or information how interaction and use of this concept in a future article might be useful. By this article alone more is expected when one read that.
Just in case I am definitely no better than him on lisp. I just expect to stand on another “giant” shoulder to learn more about this lisp approach. Sorry if I think it shortfalls a lot.
Best regards and let us move on. Good days.
