plot ((2&o.@*:t.i.100)&p.d._1;(1&o.@*:t.i.100)&p.d._1) 1p1*i:1j1000
This has two domain error workarounds which might interest people.
First, i:1p1j1000 does not work, but 1p1*i:1j1000 does. In other
words, i: has a gaussian integer domain (perhaps because that is
simpler to docu
That also.
But my point was that the "first class verb" concept being discussed
was a different one from the gerund use that you were documenting.

No, it's not a video game even if it sounds like it. It's a crowd-sourced
initiative from IARPA to improve recognition of compounds based on their IR
signature.
You need a topcoder.com login to register, which I have which is how I got
the email.
This is a more detailed intro to what they're try
This took me much longer than a lunch-break, partly because we
were away in France, and I was experimenting with J701 on my
iPad when Liz would let me.
I came up with a number of variants, of which the following is best.
It's slower and uses more space than Raul's for small problem-sizes,

J does have a gnuplot addon available for over 10 years if
my memory serves me.

and also to obtain axes' labels with mixed
symbol/italic/normal/subscript characters

I believe that this discussion was about something different.

K supports first-class verbs; one can make an array of verbs, index one out,
and apply it to something using the same syntax as for normal function
application.
This is feasable in J, but only by using a special "apply" verb (perhaps gurus
know another way?).
Not trying to go full tacit,
