Hi Hans-Peter,
thanks, I will look into this.
The general problem is that the rules how nested values with rank
≥ 2 should
be displayed are, at least as far as I know, nowhere specified in
a formal fashion.
From old APL 1 we know that the
Hi again,
checking the same in IBM APL2, the behaviour of GNU APL seems
correct.

Hi Hans-
I tried the same examples in APL/X and Dyalog APL.
APL/X seems to give the same results as GNU APL: but both enclose are indented
right by one column
But Dyalog APL has quite a different result: no blank lines between rows.

I would think what APLX or Dialog do is somewhat irrelevant. I believe GNU
APL is treating IBM APL 2 as the standard to be matched.

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.

Hi,
thank you for your insight.
