Hello Henry, Yes I'm using J9.02. I saw your explanation in the NuVoc writeup about the implied rank and had solved the problem as you show in the examples,
test2 =. 0: ` 1: ` 2: @. (3&|)"0 by specifying the rank of the test-verb instead of each gerund-verb. From the discussion at the bottom of the page, using atomic rank for the test-verb is more efficient than specifying for the gerund-verbs, right? Since test1 didn't throw a rank error for i.6, and from reading the writeup it seemed like it should, I thought I must be missing something deeper. As a J beginner I blame my understanding of the language rather than the beta. Perhaps it would be good if J9.02 also threw a rank error.
