sas虽然有do loop, while loop, until loop等等,但都只能在data 以及 macro里面应用,我该如何对proc 步骤进行一个类似于循环遍历的操作呢? 随着对sas的data step理解的加深,我认识到其实我们不能生搬硬套地将R或python里数据读取和创建的概念放到这里来,因为每个sas data step其实都是个隐式的循环!data step的...

Macro DO loop not looping through full character list in SAS Studio Posted 10-22-2018 04:53 PM (903 views) Hi, Really stumped by this one (so probably something really obvious that I'm missing). I'm trying to develop a macro with nested DO loops to cycle through all ...

second and third arguments once rather than every time the COMPRESS function is called. Using the O modifier in the DATA step (excluding WHERE clauses), or in the SQL procedure, can make COMPRESS run much faster when you call it in a loop where the ...
