我可以将有关未初始化变量的注释升级为错误吗 [英] Can I Promote Notes About Uninitialized Variables to Errors

问题描述

当 SAS 遇到未初始化的变量时，它会在日志中输出一条如下所示的注释:

When SAS encounters an uninitialized variable, it will output a note to the log that looks like this:

NOTE: Variable not_in_data is uninitialized.

是否可以让 SAS 将该消息输出为警告或错误?

Is it possible to have SAS output that message as a warning or an error instead?

推荐答案

是(在 9.4 或更高版本中):

Yes (in 9.4 or later):

option varinitchk = error;

默认值为note，其他可能的值为nonote和warning.

Default value is note, other possible values are nonote and 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；或通过将 /note2err 添加到数据语句中.我在 SAS-L 上找到了此选项更改为错误的注释列表:

There is also undocumented feature that changes certain notes to errors. You can either set the option using option dsoptions = note2err; or by adding / note2err to a data statement. I found a list on SAS-L of the notes this option changes to errors:

19   Variable %*v is uninitialized.
97   Missing values were generated as a result of
98   Division by zero detected at %2q.
99   Mathematical operations could not be performed

139  Argument to function %*s is not a known variable name:  %*v.
140  Argument to function %*s is not a valid variable name:  %*s.
205  Invalid argument(s) to the exponential operator "**" at %2q.
