SAS expert Leonid Batkhan presents the %embed macro function as a way to embed both “foreign” and SAS native code from a file into a SAS program, preventing clutter in your code.
SAS SQL handles missing values differently than the ANSI standard for SQL.

Welcome back to my SAS Users blog series CAS Action! - a series on fundamentals. I've broken the series into logical, consumable parts.
The term "fuzzy matching" describes a method of comparing two strings that might have slight differences, such as misspelling or a middle initial in a name included or not included. One of my favorite functions to compare the "closeness" of two strings is the SPEDIS (spelling distance) function. Have you
In honor of Valentine’s day, we thought it would be fitting to present an excerpt from a paper about the LIKE operator because when you like something a lot, it may lead to love! If you want more, you can read the full paper “Like, Learn to Love SAS® Like”
One great thing about being a SAS programmer is that you never run out of new things to learn. SAS often gives us a variety of methods to produce the same result. One good example of this is the DATA step and PROC SQL, both of which manipulate data. The
With the release of SAS Viya 3.3, you now have the ability to pass implicit SQL queries to a variety of SQL data sources, including Hive. Here's what happens as users write SAS compliant SQL code.
Wow did the summer fly by! Now that grad school is over, it’s about time to resume the “it’s all about the data” series. In the last several posts, I tried to lay a foundation for understanding how SAS stores and manages data for use in business intelligence and analytic
This is the fifth post in the SASonality series. In this week’s post, I’ve interviewed Rick Langston, a man most SAS users have met or read about. He’s been with SAS for 30 years and attended nearly every SUGI/SAS Global Forum. In the photo at the right, Rick is the
