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 ...
However, to do this every time you must report on a database could be an onerous programming task. But by using ODS, PROC DATASETS, and a %DO loop, you can create a macro to handle your variable and data set documentation needs for any database.William C. Murphy...
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 ...

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 ...
Second take a look at what the first %DO loop actually says from the macro processors point of view. %do i = year(today()) %to 2010 by -1 (until count ge 4); %do i= This part looks reasonable as the beginning of an iterative %do loop using macro variable I as the loop counte...
