The wiki page that you followed was written J602 wd commands. Jqt wd
commands adopted a similar but different syntax. J602 set command always
sets the 'text' property and is implied, but Jqt needs the explicit 'text'
because it can also set other properties, see wiki wd commands reference.

Hi,
Does anyone use the JQt environment for J much? I'm taking a stab at
updating and extending the code here:

If you want to map arbitrary n to a permutation with unknown length,
you could use something like this (I love J for things like !^:_1):
