Juergen, thank you for the workaround. it appears that Dyalog APL also supports 
,[2]/A A

Hi Alex,
 
 I would say that this is illegal syntax if we look at the ISO standard, but it 
seems to work in
 IBM APL2. I will try to make it work in GNU APL as well. In the meantime you 
can do this:
 
       {⍺,[2]⍵}/A A

 Hi Bug APL,

 
I am willing to admit that my syntax is actually incorrect,and would appreciate 
any help in that sense, but ,/Matrix works:
      A
1 2 1 2 1
2 1 2 1 2
1 2 1 2 1
2 1 2 1 2
1 2 1 2 1
      A,A
1 2 1 2 1 1 2 1 2 1
2 1 2 1 2 2 1 2 1 2

      A,[2]A

 2 1 2 1 2 2 1 2 1 2 
 1 2 1 2 1 1 2 1 2 1 
      ,[2]/A A
SYNTAX ERROR
      ,[2]/A A
      ^    ^

 
Even parenthesis don't work:

 
      (,[2])/A A
SYNTAX ERROR
      (,[2])/A A
      ^      ^
