Now I'd love the same with Starting Forth set to ANS Forth standards, and not just in web form. Yes, I know how to use wget --mirror and such, but I'm used to MuPDF and the editor terminal switching back and forth. No pun intended.

That's more for ANS Forth. PForth for instance has a block editor, but is not documented ( edit-blockfile file -- ).

I would love a Starting Forth book on PDF form but updated, as the web does.
