[Jprogramming] Sorting on two keys

[Jimmy Gauvin]

Hi,

I need to sort on two keys, one descending the other asscending.
(J takes care were ascending or descending

Is there a better way to solve this ?

   ]t=:5 2$7 4 8 2 8 4 7 2 8 3
7 4
8 2
8 4
7 2
8 3
   ]tt=: t {~ /:1{"1 t
8 2
7 2
8 3
7 4
8 4
   ]tt {~ \:0{"1 tt
8 2
8 3
8 4
7 2
7 4

Thanks,

Jimmy
