The following SAS program is submitted:
data ONE TWO SASUSER.TWO;
set SASUSER.ONE;
run;
Assuming that SASUSER.ONE exists, how many temporary and permanent SAS data sets are created?
A. 2 temporary and 1 permanent SAS data sets are created
B. 3 temporary and 2 permanent SAS data sets are created
C. 2 temporary and 2 permanent SAS data sets are created
D. there is an error and no new data sets are created
Answer: A
注解：DATA statement中可以同时建立多个data set，以WORK为libref或者省略libref的为临时data set，保存在WORK library下。指定其它libref的，比如题目中的SASUSER，则在该library下建立永久data set。更多关于DATA statement建立多个data set，可以参考SAS Base (35)。
The answer should be D， I think. :-))
Do you know why the answer is D?
Based on the solution or explanation from Crackman, this problem is different from yours where the first line of code ：”data ONE TWO SASUSER.TWO;“ has no semicolon.
