我下载的一个版本里给出的一个答案是错的。

第45题
ods csvall file='c:\test.cvs';
proc print data=work.dsl;
run;
ods csvall close;

what is produced as output?

a. A file named test.cvs that can only be opened in Excel.
b. A text file named test.cvs that can be opened in Excel or in any texteditor.

c. Atext file named test.cvs that can only be opened in a text editor.

d. A filenamed test.cvs that can only be opened by SAS.

给出的答案是C，但正确答案应该是B，因为test.csv是一个文本文件，任何文本编辑器都可以打开，但Excel也可以打开。
