SAS has many ways to automate and maintain any given process. Iterative DO loops and macros offer the flexibility to automate a process. At experimentation team, we were able to achieve around 70% reduction in program length and scale down manual errors via automation in our process.Arun Akk...
In SAS, a Do Loop is a repetitive control structure used to execute a block of code repeatedly while a condition holds true. It is used when we want to perform a certain operation a number of times or until a condition is met.

With those performance numbers and a sense of scale in mind, let’s add some numbers that matter every day. Let’s say our data source isX, where whatXis doesn’t matter. It could be SQL, or a microservice, or a macroservice, or a leftpad service, or Redis, or a file on disk...

Iam in process of automating SAS code,I have a macro whose input argument is date.For example:%monthly("20jun2019"d)%monthly("21jun2019"d)...%monthly("29jun2019"d)I need to automate the above code.i have tried using do loop but it didn't worked.here is the code that I have t...
Virtual Accessing of a SAS® Data Set Using OPEN, FETCH, and CLOSE Functions with %SYSFUNC and %DO LoopsOne of the truths about SAS(R) is that there are, at a minimum three approaches to achieve any intended task and each approaches has its own pros and cons. Identifying and using ...
Retain statement with do loops Posted 09-05-2017 04:08 AM (6219 views) Hi there, I currently have the following code which works a dream when replicating the first row of a dataset down to all non missing rows within the same dataset - in my scenario only the first row should ever...
