When a filing system READNEXT call is made, the status argument is used to pass to the filing system the direction of the READNEXT operation (ascending or descending). The filing system uses this direction in maintaining the select pointer. If the BASIC+ READNEXT operation designates the select list as descending, the select pointer is decremented with each filing system READNEXT operation, rather than being incremented for an ascending READNEXT.
