Re: [Bug-apl] Each bug

[Elias Mårtenson]

Interesting. Given the following definition of pp:

    ∇Z←X pp Y

    ⎕←'comparing'

    ⎕←'  X=' (8⎕CR X)

    ⎕←'  Y=' (8⎕CR Y)

    Z←X≡Y

    ∇

I get the following output:

      (⊂'foo') pp¨ (,⊂'foo')

comparing

   X=  ┌─────┐ 

       │┌→──┐│ 

       ││foo││ 

       │└───┘│ 

       └∊────┘ 

   Y=  ┌→────┐ 

       │┌→──┐│ 

       ││foo││ 

       │└───┘│ 

       └∊────┘ 

Seems to be to be a bug in the implementation of ¨ (each).

GNU APL:

IBM APL 2 returns 1 in both cases.  I had a vector I was using.  I got one result when I had 2 or more elements, and another result when there was only one element - even though it was still a vector.  IBM's result is consistent regardless of 0, 1, 2 or more elements.

Thanks.
