David and Pascal,
Yes insert produces a very concise solution that uses J's strength, too.
Thank you,

Pepe,
This solution seems to be inspired by Raul's automated version, but I
cannot be sure because the "usual definition"s are a little new and opaque
to me. Clearly it works nicely though.
Thank you,

KUAL provides extensions, one of them is Kterm which is a simple terminal
but it allows you to issue Linux commands. Is that what you are lacking?
(After that one can connect remotely wirelessly via VNC or PuTTY.) Did
you use KUAL?

I did already root my Paperwhite and it's supposed to be Linux underneath
but I haven't figured out how to remote in yet and there's no obvious
keyboard, so I don't really know how to interact with it.

This is interesting but I don't think it helps someone like me with a
Kindle Paperwhite as I believe the underlying OS is different. I do like
the Kindle's size - it has a pretty big screen but still fits into a jacket
pocket.

The original description talks about alternatively subtracting 2, then 1,
it doesn't mention detecting odd or even numbers (although the example code
does). So I'm not sure whether the following is acceptable, but it is an
example that uses power and a bit of array thinking.

I recently inherited a Kindle Touch. Of course, to be really useful it
would have to run J. Thanks to the efforts of Thomas and Marshall now it
does:

J can run under both jconsole and jhs (plot works). If there is enough

Yes, it's very satisfying, isn't it.
Mind you, your sticky tabs
probably need to have a
more practical size when N is >> 5 !
Did you

Raul,
Your explanation is great. To understand it better I tried the following,
which worked nicely. My original approach, before the explicit definition
was to us EE and OO, shown below. But apparently smoutput causes the
sequence of results to halt and I needed your 1!:2&2 idea. Your tacitizing
Actually, thinking about this, it would be nice to have an adverb
which worked something like `:6 but which gave the effect of running
the gerunds in sequence (from right to left). That way, I could
encapsulate the details of how this to encode the train and then
ignore those details after that.

This is not a good candidate for the power conjunction.
You could do it with the power conjunction but it's not a good fit.
The reasons for this are:
(1) You have two independent values you are working with - the value
you use for flow control is independent of the value you are passing
to your

I have the following verb t and wonder if anyone would like to show how it
could be more elegantly defined (using the Power conjunction?) I would
enjoy learning your result.
The intent of t is to alternatively subtract 1 or 2 from a positive number
