on the behaviour of dim_pqsort

All

I stumbled over an interesting 'feature' of the dim_pqsort() function, basically that it tries to sort a constant series (see below). I'm not sure if this counts as a bug, a warning or just evidence that I should pay more attention to what I'm doing, but it might be of use to other NCL users.
