| - | This command will sort all of the elements in the variable list and remove duplicate values in the variable list. All values in the variable list are stored as character strings. The order of numbers when sorted lexicographically is not the same as the numeric order of the same set. If a user need a numerically sorted list, the sorttype argument will convert the elements of the variable list before the set reduction is implemented. The numerically sorted variable list will then be stored as character strings after the operation; | + | This command will sort all of the elements in the variable list and remove duplicate values in the variable list.
