Re: ¨ (each) on defined function on array of empty arrays

[Dr . Jürgen Sauermann]

Hi Ben, thanks, fixed in SVN 1291. BTW: if EACH is called with a defined function then it is is computed with an internal APL function (aka. a Macro). You can display the APL code of a Macro in APL like this:       ⎕CR 'μ-Z__sA_LO_EACH_vB' Z←A (LO Z__sA_LO_EACH_vB) B;rho_Z;N;N_max   rho_Z←⍴B ◊ N←⎕IO ◊ N_max←N+⍴B←,B ◊ Z←N_max⍴0 (N⊃Z)←⊂(⊃A) LO N⊃B ◊ 0 → N_max>N←N+1        Z←rho_Z⍴Z                                   Best Regards, Jürgen On 6/1/20 2:26 AM, Ben Harris wrote: On Sun, 31 May 2020, Dr. Jürgen Sauermann wrote: thanks, fixed in SVN 1290. Thank you!  That seems to have left some more misbehaviour around "each", this time with scalars containing arrays passed to defined functions:       (⊂0 0)≡¨((0 0) (0 1)) 1 0       ∇z ← x eq y [1] z ← x ≡ y [2] ∇       (⊂0 0)eq¨((0 0) (0 1)) 0 0 Here I'd expect eq and ≡ to behave identically, but they don't.  There are no empty arrays here, so no fill functions or identity functions are involved.
