Thanks... it works!
A couple/triple of things:
I moved a saved user folder from iCloud back to jios. I'd removed the 3(?)
sample scripts, try1 ... try3. The edit window seems to be preset with tabs
for these scripts, showing <READFAIL>, I think. "Close Tab" then works for
try1 & try2, but J crashes when I attempt this for try3. I've got round this
by ' ' fwrite '~user/try1.ijs' etc. But I'd rather not have to keep these files.
There's still some issue with direct definition. Defining a script file in
iCloud with a direct definition starting "{{)n" , moving it to jios's user
folder, and then looking at it with J's Edit window reveals a gratuitous space
after )n, which messes with direct noun definition.
Jios still crashes without warning, apparently when exceeding some unknown
memory limit. For example, I've been toying with maze construction. dfmaze &
dfmazel use depth-first trees; the first is recursive, the second loopy.
ts'dfmazel 10 10'
0.000686 41216
ts'dfmaze 10 10'
0.00089 241632
ts'dfmazel 10 10'
0.000597 41216
ts'dfmazel 10 100'
0.005346 374976
NB. So far so good... and twice as fast as my laptop w Windows 11
But it crashes with dmaze 10 100
The laptop's performance here is
0.012 4.86e6
so the memory load doesn't seem to be excessive.
This is only an example; Jios crashes on larger but not massive instances in
various quite different tasks/problems, so I'm not inclined to probe the
innards of particular verbs such as dfmaze/l .
On the other hand, this is robust for q=1 to 400 at least!
ts'%.?10$~10 10*q'[q=.10
0.003218 822304
ts'%.?10$~10 10*q'[q=.400
17.5701 8.38864e8
So perhaps my various examples are all at fault.
Cheers,
Mike
