Hey Pascal,
You may be looking for symmetry where there is none. The following shows these
monadic verbs are acting as the dictionary suggests.
$ > 2; < 2 4 $ i.8
2 2 4
> 2; < 2 4 $ i.8
2 0 0 0
0 0 0 0
0 1 2 3
4 5 6 7
>@}. 2; < 2 4 $ i.8 NB. }. drops first item of argument, resulting in a
one item list
0 1 2 3
4 5 6 7
$ >@}. 2; < 2 4 $ i.8
1 2 4
>@{: 2; < 2 4 $ i.8 NB. {: returns last item of argument
0 1 2 3
4 5 6 7
$ >@{: 2; < 2 4 $ i.8
2 4
Hope this helps,
Cheers, bob
