The built-in i. will do this: i. _7 6 5 4 3 2 1 0 But I could see a way to do it with self-reference $: or with iterate ^:: (<:^:*^:a:) 7 7 6 5 4 3 2 1 0 This essentially says“iterate gathering results” ^:a:“while non-zero” ^:*“decrement” <:. This differs slightly from i. _7 because it includes the number 7, but whatever. The self-reference $: method is a little longer: 0:`(, $...
