Hi, Not sure this is a bug or not, for me, (⍳0) ≡ ⍬, so it seems that both can be replaced each other; consider below example:
a←'abc'(⍳3)99 2(⍳0)3⊃a ⍝ ≡ 3 2⍬3⊃a ⍝ ≡ 2 ⍬ 99 (2⍬3)⊃a ⍝ ≡ 3 Doesn't the second example should return 3 as first example, without the need parentheses as third example? (btw. my version is build from SVN around Oct ) Thanks, Dave
