我可以将有关未初始化变量的注释提升为错误吗

Question

当 SAS 遇到未初始化的变量时，它会在日志中输出一条注释，如下所示：

NOTE: Variable not_in_data is uninitialized.

是否可以让 SAS 将该消息作为警告或错误输出？

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；或者通过将 / note2err 添加到数据语句。我在 SAS-L 上找到了这个选项更改为错误的注释列表：
