Grade down
>x
The grade down primitive is used to get the indices of an array that would sort it in descending order.
Since grading is not the same as sorting, a general idiom used to sort arrays is {x(>x)} or other equivalent.
Grade primitives generally use a stable sort, which means that an descending grade may not always be the inverse of an ascending grade.
For numeric arrays:
>34 -1 0 67 32767 4 3 0 2 1
Grading of string arrays largely depends upon the implementation, as shown in grade up.
