DBSetOrder(0) returns FALSE but seems to actually do set the natural order. Problem exists only with DBFNTX, DBFCDX works fine.

FUNCTION Start() AS VOID
	LOCAL cDbf AS STRING
	RddSetDefault("DBFNTX")
	
	cDbf := "C:\dbf\testorder"
	
	DbCreate(cDbf, {{"FLD","C",10,0}})
	
	DbUseArea(,,cDbf)
	DbCreateIndex(cDbf, "FLD")
	DbAppend();FieldPut(1,"bbb")
	DbAppend();FieldPut(1,"ccc")
	DbAppend();FieldPut(1,"aaa")
	
	
	? RecCount()

	? DbSetOrder(1)
	DbGoTop()
	? FieldGet(1)
	DbGoBottom()
	? FieldGet(1)

	? DbSetOrder(0) // FALSE

	DbGoTop()
	? FieldGet(1) // bbb, correct
	DbGoBottom()
	? FieldGet(1) // aaa, correct
