Great news Eric. Already have many projects in mind to try out Jd.

Thank you Eric. This is indeed motivating to learn/use Jd.

I'm not so sure because I seldom use JQT or dissect. there seems an option
in config to control qt ide to load dissect during booting up. you can
check config and enable auto load.

That's great news! I echo Eric's suggestion for J users to take a look.
I've been using Jd for a few months now and it's been wonderful to work
with.
I'm working with around 10 million rows of data which is just outside of
what Excel/PowerBI can comfortably deal with and even SQL Server on a

Jd (Jdatabase) new release available.
This release automatically installs a free non-commercial key if it is run
without a key.
The non-commercial key enables all of Jd and the only limitation is that it
is licensed only for non-commercial use.
We strongly encourage all J users to take a serious
Hello Raul,
that solved my problem - thank you very much.
Thank you Pascal, too.
A new programming environment is always challenging in the beginning - and J is
quite special compared to other languages.
But I am very much motivated to invest some time in learning J:

in previous versions (and likely current status), you needed to reload jqt
after any edit of the key shortcut settings file.

Hi all,
In "Makers of Mathematics" by Stuart Hollingdale there is a reference about
Pythagoreans who where in the habit of representing numbers by pebbles in
the sand.
Figure 2.1 illustrates how square numbers can be generated by adding
successive odd numbers.

That error message means that the dissect library was not loaded.
You have several options including:
(0) load it manually
(1) have your profile load it
(2) add [ require 'debug/dissect' to the end of each of those user
keys config lines:
F2;0;Dissect Line;dissect&.finddissectline_dissect_ 0 [re
Try this:
smodd1=:+/@:>:@:+:@:i.
Your tacit verb was creating forks, as can be seen with dissect:
load 'debug/dissect'
dissect '+/1+2*i. 5'
But since the sum of the first N odd numbers is N^2
it is easiest to write
smodd=: *:

Since you have an even number of verbs in your train (1 and 2 are parsed as
constant 1"_ and 2"_ verbs) the whole is interpreted as a hook, with the
leading +/ taking its dyadic form. Your smodd1 verb is (in its monadic form)
equivalent to

Since you want to apply +/ to the resu
Hello,
I am new to J and I am very impressed by J.
Doing my first steps in learning J, I found ‚Dissect‘ and followed the
instructions in wiki/Vocabulary/Dissect#IDE to use it with PF keys:
But after putting the following lines into Edit>Configure>User Keys in Jqt
F2;0;Dissect Line;dissect&.fi
A simple Quora question wants to know the formula to sum the first n odd
numbers.
I can write an explicit verb:
smodd =.3 :'+/1+2*i.y'
smodd 5
25
I want to write a tacit verb:
smodd1=:+/1+2*i.
smodd1 5
6 8 10 12 14
What am I doing wrong?
