实际上,macro在执行当中遇到宏变量需要解析的时候,会遵循就近原则,优先解析该作用域内的宏变量,如果该作用域内不存在该宏变量,则向上递归查找该宏变量,直至最外层,如果找不到则在当前作用域内创建该宏变量。 可以利用SASHELP这个library当中的view - VMACRO来验证: %let nobs = 19; %macro chgNObs(); %let ...
很多人都知道,macro和loop结合可以成为灵活而强大的SAS程序开发工具,但他们并不是唯一的,还有其他一些有用的工具。最近发现call execute是个很灵活很多变的工具,值得花点时间掌握它。 了解SAS do loop的同学都知道,do loop只能放在data step中。这令很多来自于其他编程语言的同学不太习惯,如果我想循环执行某个proc ...
