Thanks for that link. Do you know if the results are posted anywhere? https://shakti.com/license.php says "Customer shall not... distribute ... any report regarding the performance of the Software benchmarks..." which I would need to agree to if I want to download the binaries at https://shakti.sh/benchmark/

You could check and see if it was ever posted on the Shootout site with archive.org, but when I checked coverage was spotty. The point of these benchmarks is everyone being able to run them themselves, though.

No, K was never installed.

Exactly.

And compare with programs in some other language:

Subjectively, APL is pretty and enticing in a way that J isn't. It's very strange to me that someone who promoted Iverson Notation as a better math notation, and wrote Notation as a Tool of Thought, could apparently completely switch notation from 30 yea…

It's also easier to do scripting with J since you can just use files. The (Dyalog) APL workspace infrastructure is very powerful but a bit heavy to use when all you want is a simple script. Of course, large banks and Fortune 500 companies seldom use just simple scripts, so that makes sense I guess.

Afaik the newest version of dyalog can run so. 'dyalog -script whatever.apl'
