Re: [Bug-apl] An other question about "⍶"

[Juergen Sauermann]

Hi Christian, correct. In GNU APL you cannot use values in defined operators where functions are expected, except for very few primitive operators. A work-around for a third value in lambdas is to use the axis χ instead of function ⍶:       FOO ← { ⍺ χ ⍵ }       1 FOO[2] 3 1 2 3 /// Jürgen On 05/18/2016 09:59 PM, Christian Robert wrote: Looking at  https://www.youtube.com/watch?v=DmT80OseAGs Every thing goes fine (when he says "take" and use "⊃" you write "↑" instead in gnuapl) [...]       88 {⍺ ⍵} s44 88 ┌→──────┐    ↓0 0 0 0│    │0 0 2 1│    │3 0 0 4│    │0 0 0 0│    └───────┘ at the minute 03:41 it fail with a syntax error       88 (3 2 {⍺ ⍶ ⍵}) s44 SYNTAX ERROR       88(3 2 λ1)s44       ^         ^ Does this means that in gnuapl "⍶" cannot be data ?
