It's probably worth noting here that (for example) the quicksort

0 1 result can't distinguish between ordering and equality. Many

Looking at this, the domain errors do seem analogous to divide by zero errors.
So, in the context of %m.n, if we were being purely symmetric, a 0
result when both the numerator and denominator were effectively 0
would be the way to go, with an infinite result for the remaining
cases.
Actually, https://code.jsoftware.com/wiki/System/Installation/J9.5/Zips

The browser displays the message: "j9.4_win.exe isn't commonly

below that line is a "See more" link (or maybe pseudo-link -- it's

I think boxing each line and discarding the unwanted lines is a good
approach here.
For example:

That said, I guess you could do something like this:
require'regex'
,d rxfrom~'^.*\S.*$' rxmatches d
Or, equivalently:

open 'ide/qt/gl2' works.
I do not know why open 'gl2' silently fails.

I remember "foo" showing up a lot in some boston related contexts, and
a quick web search finds:

https://en.wikipedia.org/wiki/Ruby_Foo

The recent change in directory naming from j903 to j9.4 introduces an
interesting issue for shell scripts on unix-like systems.
In J shell scripts, this works:
#!/home/username/j903/bin/jconsole
However, this fails with a spelling error:
#!/home/username/j9.4/bin/jconsole

The problem is this line of install-usr.sh:

That final 9.4 is the priority of the alternative. It should probably be 904.
(A higher priority alternative overrides a previous priority, and this
