            This command allows the developer to set or get the currently selected sort direction for the current
            process. If a valid direction is specified, this routine will make it the default direction for subsequent sorts,
            until the user changes the sort direction setting.
            Pass 1 for an ascending sort, or -1 for a descending sort.
              Fnd_Sort_Direction (-1) ` Descending sort.

            This function also returns the sort direction set for the current process, so it can be stored for later use in
            another process or the next time the database is used.
