Jared's post reminded me how awkward it seems to get multi-line numeric data into J. A job that begs for a direct copy/paste requires more, to me.
I realize that the new direct definition feature simplifies this somewhat, but I have been looking into this task without such. I don't think the reference card would demonstrate the complexity of the (simple?) task I suggest below.
