Re: [Bug-apl] axis specification with scalar dyadic functions (2)

[Christian Robert]

NARS2000 give:

     a←2 3⍴.1×⍳6
     b←2 3⍴⍳6
     a + b
1.1 2.2 3.3
4.4 5.5 6.6
     a+[1]b
LENGTH ERROR
     a+[1]b
      ∧
     a+[2]b
LENGTH ERROR
     a+[2]b
      ∧

looks like something *I* do not yet master. Ah the newbies ... they talk, talk 
and it's just wind.
