On the fork page, vvv and nvv share a row, and that’s for a good reason.
FWIW I added the NVV entry to that page, and I added it to the same row as

mention of y.)
Another good reason to write it that way: the resultant verb is ambivalent.

In the original code snippet, the argument was '', so I assumed it didn't
matter. Actually, I originally wrote it as an adverb, then realised it

However, it occurs to m
I forgot: it doesn’t /need/ to be an adverb:
replace m by x, and you’ll get the same functionality
with type 'seeq' returning <'verb' but I think
adverb better fits the purpose.

Gee, guys, I wasn't saying I would remove `:0, or even that I wanted
to. The language doesn't belong to me. We only make incompatible
changes when we realize something should never have been implemented or
was wrongly implemented.
It's nice to know there are applications for `:0 . A suitabl
I'm not a pro developer in any way, but my job entails some data analysis.
Executing multiple verbs on the same data is something I do whenever I'm
extracting distinct feature vectors or summary stats from raw data.
Also, same thing when working on trees Hsu-style. I'd be sad to see :0 go!
Just my
Huh. That's a strange thought to me.
I execute a bunch of verbs on the same arguments **all the time**,
especially when I'm working with input/output or mutable data:
- parser combinators
- virtual machines
- terminal i/o
Usually the argument in question is the empty string or some kind of state
I would vote to delete u`:0 rather than extend it. Executing a bunch of
verbs on the same arguments? Not a very useful thing I think.
Using [ to separate executions is The J Way. Very efficient. Train
yourself to get used to it.
Newlines are even better. Then you can put a comment on each
That is unfortunate. Normally, I am perfectly comfortable with [ and @
to do function composition, but sometimes I really wish to convey the idea
of a sequence,
and it just doesn't feel like the same thing as function composition to me.
(So I prefer newlines to [ or @ in these situations, but th
You cannot count on the order. All you know is that each cell of the
result corresponds to an AR in the gerund.
To execute short sentences the usage
sentencen [ ... [ sentence2 [ sentence1
can't be beat unless one of the sentences produces a modifier.

J903-beta-s is available for windows/linux/macos.
If you already run J903-beta, then upgrade is easy:
load'pacman'
'upgrade'jpkg'jengine'
If you have not yet installed J903-beta, time to get started!

Today I discovered that `:0 executes the gerund in series from left to
right.
The execution order isn't specified in the docs (as far as I can tell), so
I wonder if it's an implementation detail subject to change, or if I can
rely on this?
Almost all of the cases where I want '..' as a statement
my fault: I didn’t mean to show VVN as a fork
I should have just said 'execute immediately' there

No, we release when we think there are no major features to add. It's
