Hi Bob, thank you very much, that helps indeed. It seems, I have had a too minimal approach towards J. I worked through a lot of material like, e.g., Roger Stokes excellent book on learning J. But this material mostly focusses on the J primitives.
Probably that left me with the impression, that you have to build everything yourself and so I built a lot of stuff for myself which might already be part of the standard library. I will have to give a closer look, I think...
