Hi again,

Now I'd like to remove that printing hack in my program. I knew it was a
hack and it won't help with the next bit.

In principle, I want to build a list recursively using some function to
generate each element from the previous one, up to a certain length. I tried
it with /\ but just got strange results:

   (2*[)/\ 2 3 4
2 4 4

and had trouble doing it the long way:

   inc2 =: 2&+

   app =: (] , inc2@{:@])
   app (2 4 6)
2 4 6 8

   app2 =: (] , [@{:@])
   inc2 app2 (2 4 6)
4 6 8 8

I don't understand what's happening here. Please help. Isn't there something
out of the box for this?

Adrian.
