The little SAS program’s official name was Extract_Transform_Load_ 0314.sas. But, that name was much too formal, way too long, and did not roll off of the tongue very easily at all. So, everybody simply called her: ETL Pi. ETL Pi was conceived in a 2-hour project strategy meeting in conference

If you're a SAS programmer, you have likely used loops in your SAS code to make life easier from time to time. In this blog post, I demonstrate a few ways you can use loops to do clever things in your graph code. Perhaps even the old dogs can learn
When developing SAS® data sets, program code and/or applications, efficiency is not always given the attention it deserves, particularly in the early phases of development. Since data sizes and system performance can affect a program and/or an application’s behavior, SAS users may want to access information about a data set’s
I recently asked a SAS user, “Which interface do you use for SAS?” She replied, “Interface? I just install SAS and use it.” “You’re using the SAS windowing environment,” I explained, but she had no idea what I was talking about. This person is an extremely sophisticated SAS user who
Editor’s note: This is the first in a series of articles to help current SAS programmers add SAS Viya to their analytics skillset. In this post, SAS instructors Stacey Syphus and Marc Huber introduce you to our new Introduction to SAS Viya Programming for SAS 9 Programmers video library, designed to show SAS programmers how they can
What?!? You mean a period (.) isn't the only SAS numeric missing value? Well, there are 27 others: .A .B, to .Z and ._ (period underscore). Your first question might be: "Why would you need more than one missing value?" One situation where multiple missing values are useful involves survey data. Suppose
In a previous blog, Random Sampling: What's Efficient?, I discussed the efficiency of various techniques for selecting a simple random sample from a large SAS dataset. PROC SURVEYSELECT easily does the job: proc surveyselect data=large out=sample method=srs /* simple random sample */ rate=.01; /* 1% sample rate */ run; Note:
How many of you have been given a SAS data set with variables such as Age, Height, and Weight and some or all of them were stored as character values instead of numeric? Probably EVERYONE! Yes, we all know how to do the old "swap and drop" (rename and convert), but
This SAS Jedi is very excited about the SAS 9.4 M4 release, which brought many wonderful gifts just in time for Christmas. So in the interest of extending the Christmas spirit, I'm going to blog about some of my favorites! I've long loved the SAS DO statement variant which allows
SAS temporary arrays are an underutilized jewel in the SAS toolbox. I find that many beginning to intermediate SAS programmers are not familiar with temporary arrays. The good news is that there is nothing complicated about them and they are very useful. First of all, what is a temporary array?
