Note that this would be a dictionary change. http://www.jsoftware.com/help/dictionary/d610.htm says Moreover, m`n is m,n and m`v is m,av and u`n is au,n . The existing logic can be used, for example, in constructing array constants: M=:i.0 0 M`2 3 5`1 2 4`0 1 1 2 3 5 1 2 4 0 1 1 This seems obscure enough that probably not a lot of code uses it. But it is a dictionary change. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
