I was trying examples of APL code from the book "APL2 At a Glance" in order to become more familiar with APL2 features. I found an example that doesn't work.
]BOXING 8SA←10 'ABC' (3 3⍴⍳9) 20 (5 6)SA┌→────────────────────────┐│10 ┌→──┐ ┌→────┐ 20 ┌→──┐││ │ABC│ ↓1 2 3│ │5 6│││ └───┘ │4 5 6│ └───┘││ │7 8 9│ ││ └─────┘ │└∊────────────────────────┘

So far, so good. But when I try the selective assignment I get
(,2 2↑3⊃SA)←'WXYZ'SA┌→──────────────────┐│10 ┌→──┐ Z 20 ┌→──┐││ │ABC│ │5 6│││ └───┘ └───┘│└∊──────────────────┘
when according to the book I should get
┌→────────────────────────┐│10 ┌→──┐ ┌→────┐ 20 ┌→──┐││ │ABC│ ↓W X 3│ │5 6│││ └───┘ │Y Z 6│ └───┘││ │7 8 9│ ││ └─────┘ │└∊────────────────────────┘
which is what I would expect.
I hope that this information proves useful.
I am having fun experimenting with GNU APL and exploring APL2 features.
