Actually, I originally had LF,LF until someone pointed out that LF2
was in stdlib.
That said, other parsing approaches for the day 1 data are perfectly viable.
For example:
+/|:".@;S:1 cutLF each cutpara data

Perhaps you copy and paste from email to J and it contained nonbreak space
that visually identical to a normal space.
Typing it manually may solve your problem.

Going to

Note that, depending on the resource being limited, ulimit may cause
the process to crash or shut down when that resource hits the limit.

Here's the parsing routine I used for day 1:
parse=: {{ +/@(__&".;._2);._2 (y,LF) rplc LF2;LF,'/'}}
Its y argument would be the raw text of the input.txt provided for day 1.
I hope this makes sense,

Here's a cleaned up version of how I approached that (here 'input'
held the raw text of input.txt provided by the aoc website).
parsed=: ('ABC',:'XYZ') i."1 |:-.&' ';._2 input
part1=: {{ +/1+y+3*3|(1+y)-x }}/
part2=: {{ +/(3*y)+4|&.<:x+y }}/

Run jbreak twice to interrupt the running sentence (at the next point
where it allocates memory, which is often). A single Jbreak interrupts
only at the end of a sentence.

Rebooting is a bit drastic; can you not kill j from task manager?
Beyond that, break _should_ work. I can look into making it a bit more
responsive for long array operations, but am curious to know what specifically
has caused you trouble.

This is a serious known issue in jios. But since you say "Windows laptop" I

As far as jios is concerned, all I can say is: I'm working on it.

Hi!
Is there any way to avoid the situation whereby by error I put J into an
infinite loop from which the only recovery is to reboot my Windows laptop?
I guess that my erroneous routine is locking the CPU to such a such an extent
that I can’t even get to run Jbreak.
