What is the difference between 2 (a list of moves for the current
board) and 3 (a path list for the solution, initially empty) in this
description?
Thanks,

Sorry about the typo.
It's pretty late now. Will revisit your message in the morning.

The gap between J and most computer languages is pretty wide.
Maybe this will help.
The board, a noun, is represented by a 15 element binary array with 1s for
full positions and 0s for empty ones. It is initially all 1s. Id, a noun,
is a 15x15 identity matrix.
Function flip, given a board and po
@Henry,
I think I have found out why g530 had failed,
there was already x=:.. defined eariler,
and today's patch adding local name x=. as in
'agifuwy' -: 3 1 ((5!:1<'x')`[`])} 'aeiouwy' [ x =. 'fg'
therefore there are 2 instance of x (one global, one local)
the 4!:55 at the end had erased only o
That is interesting, right now, for

That's a nice idea. Leads also to this rephrasing of that part:

Or, in context:

Right, I made and push that change. However I still encountered the
same failure at g530 on run RUND1 ddall as Bill had reported.

IIRC I experimented in ge.ijs with a system of automatically deleting
the definitions created in the script. As Bill says, that method would
leave x y u v m n undeleted. The fix, which I assume he is talking
about, would be to delete those names willy-nilly at the end of the script.

Thank you for report. the problem is that nl'' exclude reporting
x and y. I will push a fix.

I have seen the problem with g530 once (today), but running:
xxx> $j32
load'~/tmp/jsource.git/trunk/test/tsu.ijs'
1 RUND2 ,268 { ddall
triggers the problem, and explicitly deleting x and y at the end of
ge.ijs "cures" it (it's full of x =: ... and y =: ... ).

there has been a recent change in g530 that add x=. please confirm if it is
the culprit.

Now that in-place assignment is available for most occurrences of m}, is
doesn't hurt performance to use modifiers to make things easier to read:

a =: 'fg' (3 1 replace) a NB. Parentheses optional

Well... the result is not the same here, because 2 3 is different from 1 2.
That said, <@, produces the same result as <@:, for the same
arguments. The difference between @ and @: would

Hi,
My iPad 3 (32 bit I think) cannot go any higher than IOS 9.
I presume this new version will not run on it, but I would like to have the
'real improvements to the user interface'. Any chance of backward compatibility?
Regards, Rob.

I have difficulty in reading your code, perhaps you want to
make everything looks functional. To that end, you may
replace the if/then with @. (agenda)

Odd, that's the KISS way, the way that always works, and the one way I
hadn't considered.
On to your "simplifications."
