>> what good will J do for me? > The best would be to learn it and see it for yourself. I've found the statement on the front page of jsoftware.com to be rather accurate: "If you are interested in programming solutions to challenging data processing problems, then the time you invest in learning J will be well spent." And "data processing problems" could be understood pretty widely. I've had a case when I first spent about 45 minutes producing a prototype (a program which would generate realistic plans for floor of an office building) using J, then converted that prototype in functionally equivalent (no embellishments) program in C# spending a couple of hours. Certainly working on a prototype took several failed attempts, yet it was still faster than doing the same in C# after the algorithm was already clear.
