Yes - it fails gracefully in JQt 807, and it also fails in a reasonable
fashion in the older
J701 on the iPad; I attempted to give an idea of J's error-handling in
each version.
(12.4.5 is the version level of iPad's iOS operating system.)
I didn't try it in my own installation of 901, assuming it would crash
as it had for you.
However, I HAVE now tried
load 'plot'
'ylog 1' plot 1 0 2
in a new JQt session of version 9.01 and find the same reasonable
error-handling
behaviour as for version 8.07: it does NOT crash on this machine/in
this JQt 901
installation.
So maybe there's an installation problem in your case.
Cheers,
Mike

Do you mean that jqt807 on Win10 does not crash, while a newer J crashes
on your iPad?
I noticed more crashes in the past while trying to use 'plot', for me it
is enough to
load 'plot'
plot 1 2; 3 4 5
There is an error message and after like 2 seconds the whole session
crashes. Do others also see this?
A related question is, what ploting utility would you recommend for
*interactive* investigation of data, that would easily cooperate with J,
if possible.
I know there is a gnuplot addon, for instance. Do you have any
experience with it? (I would like to be able to zoom into parts of the
graph, 'plot' does not allow this) Or do you just produce a data file
and plot it seperately with a comletely external tool (matplotlib;
roassal from smalltalk; some javascript in a browser like d3js...;
grace)?
Thank you
