&nbsp;&nbsp;&nbsp;&nbsp;  set SASUSER.ONE;<br>
  run;<br>
<br>

&nbsp;&nbsp;&nbsp;&nbsp;  B. 3 temporary and 2 permanent SAS data sets are created<br>
&nbsp;&nbsp;&nbsp;&nbsp;  C. 2 temporary and 2 permanent SAS data sets are created<br>
&nbsp;&nbsp;&nbsp;&nbsp;  D. there is an error and no new data sets are created</font></p>
<p><font size="4">Answer: D</font></p>
<p><font size="4">本题考察的是语句结尾注意分号的问题。<br>
在SAS里面一般一条语句都是以分号作为结束标志。<br>
本程序中第一条DATA步 后没分号。所以答案为D。</font></p> <a href="http://hi.baidu.com/crack%5Fman/blog/item/0ae57b8fee6ae102c9fc7ae7.html">阅读全文</a>
