The base library had assumed all JFE had defined BINPATH, but
apparently this is not always true. Fix will be in the next
base library update. Thank you for reporting this bug.

Iospacman.txt is decommitted, there will be other ways to move files in and out
of j ios and more addons might be bundled inside j ios assets.

I am glad, thank you for bringing 3!:2 and 3!:1 to my attention. There
could be a high performance price to pay for going fully tacit from half
way tacit, not to mention, from explicit (which is another issue):
v0=. 3 : 'R=. R , y'
v0
3 : 'R=. R , y'
v0 1 2 3 [ R=. 0
0 1 2 3
lr

I agree with Don's suggestion. I've also found things like "++" to be a
little notational wart in the C; it extends to "--", both pre- and post-fix
forms, but is similar to nothing else in the language. Learning about it
gives you nothing of value that's generally applicable elsewhere.

Thanks, Eric. Sorry for the delay - watching Wimbledon & out for a while.
Yes - it seems fine in portrait mode.
It's not immediately obvious that there are three sections of display;

I am indeed not entirely sure what you are thinking of, but you can do
stuff like this:
nrep=: '3!:2 a.{~',&":a.i.3!:1
".nrep 1 2 3
1 2 3
That said, if you really want 5!:5 functionality but as a verb, and if
the use of : to construct that verb is a real problem for you, there's

Eric,
Is there a file which j701 reads on startup,
or is there another way to avoid having to type
load 'my_profile'
every time?

For information about J forums see http://www.jsoftware.c
"you cannot avoid referring to the name"
That is precisely the problem. If one intends to use ". , to solve the
original request, then the linear representation of the argument is
required and you have to name it. Hence,
lrep=: 3 :'5!:5<''y'''
lrep 1 2 3
1 2 3
works. However,

With a bit of work and documentation of steps at the wiki it will soon be
possible to to put addons on J iOS.
New documents and document exchange within your own environment (your
desktop to your device) is more clearly within the Apple rules than
download from Jsoftware.
Here is a rough sketch:
It is not about pointlessly updating the libraries, but rather a simple way
to download more addons.

Ok, I won't do this:

But this, in the plot lab, is disappointing:

Thank you Eric!
I've just tried j701 on my iPhone 6+. The new keyboard
is a *vast* improvement making the entry of the most common
characters much more convenient.
My phone was jailbroken for years, which made it easy to
move files onto the J app, but eventually I was forced to
upgrade to t
you cannot avoid referring to the name, but there's no need to use the
: conjunction for this.
For example:
lrep=: [: ". '5!:5 <''',,~]
lrep 'lrep'
[: ". '5!:5 <''' , ,~ ]
Thanks,

Why? Is this accomplishing anything ? Is the value of t changed?
t=:1 2 3
t+3 or 3+t give 4 5 6 but t is not changed
to have a change in t then t=:t+3 works and its meaning is clear.
I would suggest that the value of J (as with APL) is that it is not C
and non-C thinking is a benefit.

The folder structure in J iOS is a bit different. I think it would be a
mistake to worry about things like updating the base library. Why not just
use what is already there? Updating for the mere sake of updating doesn't
make sense.

What a coincidence that this type of question was posed a day after I

Looks like the new Iospacman.txt updated by bill lam is working again, but the
updated base library cannot be loaded, because JFE doesn’t have BINPATH defined.

UGH. A bug introduced at the last minute (making landscape keyboard buttons
taller - so they were square) broke landscape keyboard on all devices. This
is in addition to the initial confusion of not seeing the help html view if
you start out in landscape.
I want to wait a bit to see if there are o

I was too enthusiastic last night to report that landscape is broken.
The problem is worse than you indicate, only the top 4 rows of the keyboard
appear in landscape, i.e. a s d f...k l ' and the control row below are
missing. When the keyboard is dismissed before rotation, the scrolling area is
I think I see the problem you report with landscape. Everything is working
as intended, but the html view (where ? and plots are displayed) is not
seen because the screen is taken up with the keyboard and log area. There
just isn't enough vertical space.
Please run J again in landscape and dismiss
Oh!
I rotated the screen, so moving from landscape to portrait, and

Sorry, I prefer l/scape most of the time. Prepared to use Portrait, but
shouldn't landscape work too?
