I was using a machine that did not have J installed. I needed to do a little bit of calculations that would be easy in J.
I was thinking about downloading J to be able to do what I wanted. Then I saw I could use J directly on the web without doing download. https://jsoftware.github.io/j-playground/bin/html2/# That was very convenient and solved my needs. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
