I would just like to share a thought for anyone making material for beginners
in J.
I know that the NuVoc has been recently implemented and I find myself always
referring to it. For a J beginner like myself it is indispensable. And the J
reference card (which I printed out and often browse) is also a great help.
But a quick suggestion to anyone who is continuing to make material:
This brief introduction
www.jsoftware.com/books/pdf/brief.pdf
has several great diagrams (page 17). I found this PDF a couple of weeks ago,
and just looking at those diagrams it all clicked, in the sense that I pretty
much instantly understood how J function composition works, in general. I wish
I had found them earlier, and also wish these diagrams figured more prominently
in material. (I now the ref card has diagrams for hooks and forks)
This is just an observation that might help.
Regards.
