Thx for your kindly reply, for question 2) I find out that it's because the version of my office is 32bit, and now I reinstalled a 64bit version, the problem solved. But for question 1, I still don't have any idea of what to do, because I'm a new learner of SAS, no experiences in coding. The SAS 9.4 is the newest I suppose, becasue I just installed and uploaded it. Is it because when I installed it, I didn't choose utf-8 as a default option? should I just reinstall it with utf-8? Regards.
