The following expression should work, if I'm reading the ISO spec correctly:
⊃ 3 (1 2) (2 2 ⍴ 0 1 2 3)
It does work on Dyalog, and gives the expected result.

And what is the correct answer?
I tried it with APL/X 5.1, and i get the same “RANK ERROR” as in GNU APL.
If i understand disclose correctly, the right argument are nested elements, but
of a shape that allows for them to be laminated into a matrix as a result.
Having a scalar, a vector and a ma
What does IBM APL 2 do?

Hi Elias,
thanks, fixed in SVN 1485.
Best Regards,

Strange, because when i tried it in Dyalog 18, the result is only the number 3,
not the matrix you got.
display 3 (1 2) (2 2 ⍴ 0 1 2 3)

Well, for each element that has lower rank than the highest-rank element in
the list should be rank-extended by prepending 1.
In other words, in the example I gave, the maximum rank (last element) is
2. The rank-1 element (the second one) should be extended to (1 2) by
prepending 1.
Thus, the res
In Dyalog, did u change the Quad ML setting?
Because this is definitely not the result i am getting

Very interesting.The APLX manual is quite explicit in that all element of the right argument must be of the same rank or a scalar. So the rank error makes sense.Dialog, as usual, doesn't fail to surprise.At ML 1 Disclose behaves like Pick and at levels 2 and 3 it extends rank, not just shape as A
