想知道如何在 SAS 宏中实现 %input 吗？
Wanna know how to implement %input in SAS Macros?
谁能帮我在 SAS 中使用 %input 宏语句。我通过谷歌搜索知道 %input 是用于创建宏变量的宏语句。
%INPUT 只应在遗留情况下使用。
文档（如果您阅读的话）说明了使用条件。
Details
The macro processor interprets the line submitted immediately after a %INPUT statement as the response to the %INPUT statement. That line can be part of an interactive line mode session, or it can be submitted from within the Program Editor window during a windowing environment session.
这意味着您正在从控制台输入值或在 程序编辑器 中提交代码。从默认增强编辑器或 SAS 服务器提交时，%INPUT 将导致错误。
