It works in Xy4DOS that way too. That could explain why people think it has to do with a path stack: if you issue CD with no argument, it goes to the previous directory. A stack of one item.QS has to be a carryover from Xy ties to Atex. As I recall, the Atex command for changing directories (ques) was QS. For me, using XYWIN, QS works as well as CD.
