Ooooh, fighting words if you wander into a Forth bar.
The attraction of threaded code is that it stays in cache. J has that
advantage too. But J is not compiled & so doesn't fit the paradigm exactly.

I made the same assumption as you when first hearing the concept of threaded
code. If you read the link, it has nothing (or little) to do with single vs
multi threaded code.

Subject: Re: [Jprogramming] threaded code
Yes - mostly (but not entirely) as something to be avoided.
You can emulate threading with gerunds, if you are also willing to maintain
a stack. J's implementation also has contained some overhead from threaded
attempts which wound up causing more problems than they solved. But mostly
threaded code winds up being a lot of wasted motion, in the context of the
kind of program which J is well suited for.
Threaded code can be nice, however, for fast animated contexts, such as
games. J is suitable for tools to edit data structures used in games, and
it's suitable for exploring concepts useful in games, but I think you'll
need to refactor a threaded game architecture before using J to implement
it.
That said, threading can also be nice for servicing user interface
mechanisms. If jqt had a way of interrupting a J program, the interrupt
servicing code would need to be an independent thread.

Does this concept apply to J's implementation in any way?
