Dear Jsoftware, (2nd attempt to post this - hope it doesn't come twice now)
I have matrices where the elements are boxed lists of numbers. I want to combine the lists in neighboring positions of the matrix and I am using ;. for that. A trivial example is: $ ijconsole-8.07 JVERSION Engine: j807/j64/linux Release: commercial/2018-10-04T15:00:41 Library: 8.07.20 Platform: Linux 64 Installer: unknown InstallPath: /usr/share/j/8.07 Contact: www.jsoftware.com ]P =: <"0 i.3 4 ┌─┬─┬──┬──┐ │0│1│2 │3 │ ├─┼─┼──┼──┤ │4│5│6 │7 │ ├─┼─┼──┼──┤ │8│9│10│11│ └─┴─┴──┴──┘ 1 2 <@:; ;. _3 P ┌───┬────┬─────┐ │0 1│1 2 │2 3 │ ├───┼────┼─────┤ │4 5│5 6 │6 7 │ ├───┼────┼─────┤ │8 9│9 10│10 11│ └───┴────┴─────┘ NB. So far so good. But when I want to see P again, the system crashes: P Segmentation fault (core dumped) $ I tried it in windows as well, with the same result. In j64-806 (and earlier) it used to work. Perhaps I should do something different, but my "real case" is much more complicated and I'm not looking forward to turning it upside down. Could there be something wrong in the interpreter?
