[Jprogramming] @: and capped fork

[David Ward Lambert]

Sadly, the current j version 7 version of the "Object Oriented
Programming" is broken.

Lab: Object Oriented Programming
To advance the lab, press Ctrl-. in JHS or Ctrl-J in Gtk.
On a tablet your mileage may vary.

── (1 of 70) Overview ───────────────────────────────────────
This lab is about Object Oriented Programming.

It covers OOP ideas and terminology and shows how to do it.

-----------------------------------

I was struck, by an earlier post in this thread, of differing
impressions of j.  I see j as having been carefully crafted with names
and symbols carefully chosen.  Were I to offer an introduction for
intended users, say to a j club, the circle functions o. would be among
the first things I'd show off as mnemonic, easy to learn.  Then again, I
think the standard emacs key sequences make good sense.  My only gripe
is that having been a Pascal programmer, and a Makefile writer, and a
Mathematica user, I often write  noSpace:=  causing spelling error that
gives me a devil of a time to spot.
