Thanks, Ian.
I've just tried closing the edit tabs again. The last remaining tab showed

it. No idea what's changed! So it seems you're ok there.

Mainly for Ian, I expect.
I’ve been playing with Raul Miller’s “countdown” solution as listed in

Actually, I’ve modified “task” slightly, in order to force the target number
and the selection of the 6 numbers.

These seem simpler and are possibly quicker, at least in J701 on this oldish
iPad:
100 (1{I.@E.) A NB. Fails if there’s no (second) 100 in A
719
100 ({.@}.@(I.@E.)) A NB. Returns 0 in that case
719
Easy to correct for such errors, of course.
I tried
A =. ?100#1000
find2 =: 13 :
I’ve just tried that on this iPad, running J701, as it’s only at iOS 12:
1x 1x I.1x 1x
2 2
0 1x 1x I.1x 1x
1 1

J701 still runs on this iPad, running iOS 12.4.9 .
But, in response to your query, I’ve just installed it on my wife’s much newer
iPad, running iOS 14.3. It seems ok there at first glance.

Thanks. Yes, agreed. I’ve avoided/not needed la/Tex in the past. Searching
the J wiki
throws up quite a few articles on rendering J and APL in laTex, but I didn’t
find anything
going the other way.
I might have a look in Knuth’s mighty tomes.

Weird! But thanks for the special treatment, or should that be general

And yes, both this iPad, and “Mailwasher” on the laptop show it as to me.
Clicking on my moniker in the iPad mail system reveals “to (me)”, “other -

Mailwasher’s email info tab shows

I tend to take the iPad out with me after updating the script I'm
working on
with a jjget from the less mobile laptop. I tweak the script a bit
perhaps, and
jjput the newer version. There are minor problems with the editing
process,
but worth it for the mobility.
The trouble with your mail
Fwiw, this runs ok under J701 on the iPad, iOS 12.0 as expected?

... was that with the M. memoiser? It seems fine without M. in all J versions.
And I expect it's ok (with M.) on the Mac book if J807; ok on iPad for smaller
args, but fails for larger values, somewhat unpredictably; though 1000 should
kill J every time. If and when it fails on the iPad, the
It looks as if the crash might have been a general J701 feature rather than a
problem with the iPad implementation. I don't now have J701 on the laptop, but
do still have a zipped J602 which I reexpanded yesterday, while away from
WiFi...
So, it turns out that invocations of f10, memoised
r work would probably be wasted. But

If it turns out the localstorage is a problem, I can easily make a version
which ignore the error. It is not required for function, but only for
