我可以将关于未初始化变量的注释推广到错误

Question

当SAS遇到未初始化的变量时，它会向日志输出一个如下所示的注释：

NOTE: Variable not_in_data is uninitialized.

是否可以将SAS输出该消息作为警告或错误？

Answer 1

是（在9.4或更高版本中）：

option varinitchk = error;

默认值为note，其他可能的值为nonote和warning。

还有一个未记录的功能可以将某些注释更改为错误。您可以使用option dsoptions = note2err设置选项;或者将/ note2err添加到数据语句中。我在SAS-L上找到了一个列表，该选项会更改为错误：
