From crackman's blog on Baidu

44.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: D
本题考察的是语句结尾注意分号的问题。 
在SAS里面一般一条语句都是以分号作为结束标志。 
本程序中第一条DATA步后没分号。所以答案为D。 <a href="http://hi.baidu.com/crack%5Fman/blog/item/0ae57b8fee6ae102c9fc7ae7.html">阅读全文</a>
