你现在写的code 是虾米啊？

Alrighty, here is the situation. I bought this SAS student version 8.0.
But I always have problems importing data into the program. So I chose
to directly save data sets in sas format, in that way, I can directly
have SAS read them. However, recently, the damn library in SAS didnot
work for some reason. Basically, I have this directory in my computer
set up for all the sas programs and datasets, I used to be able to use
library to locate and open these programs as well datasets. But not
anymore. Does anybody know how to deal with this?
