Which was sort of my point: APL/X and GNU APl have almost identical handling to that of IBM APL2.
i’m sorry if that was not stated clearly enough. The three of them: APL2, GNU APL and APL/X have almost identical handling of that issue. Dyalog is clearly the odd man out. > On Aug 26, 2021, at 13:26, Blake McBride <blake1...@gmail.com> wrote: > > I would think what APLX or Dialog do is somewhat irrelevant.
