Principal Technical Training Consultant

Mark Jordan (a.k.a. SAS Jedi) grew up in northeast Brazil as the son of Baptist missionaries. He served 20 years as a US Navy submariner, pursuing his passion for programming as a hobby. Upon retiring from the Navy in 1994, he turned his hobby into a dream job and has been a SAS programmer ever since.

Mark writes and teaches a broad spectrum of SAS Foundation programming classes, and is proud to announce his first book, “Mastering the SAS® DS2 Procedure: Advanced Data Wrangling Techniques”.

When he isn’t writing, teaching, or posting “Jedi SAS Tricks” here on the SAS Learning Post, Mark enjoys playing with his grand and great-grandchildren, hanging out at the beach and reading science fiction novels. His secret obsession is flying toys – kites, rockets, drones – and though he usually tries to convince Lori that they are for the grandkids, she isn’t buying it. Mark lives in Toano, VA with his wife, Lori, and their cat, the amazing Tiger Man. To connect with Mark, check out his SAS Press Author page, follow him on Twitter @SASJedi or connect on Facebook or LinkedIn.

In the previous episode, we built our own custom SAS function - a masterful trick indeed. Gordon Keener, a developer here at SAS, responded exuberantly "You think that's cool? - try THIS!" and proceeded to demonstrate prodigious powers with the SAS by using a custom function in a custom informat

Jedi SAS Tricks: Some Experience Required

As a Master Chief in US Navy submarines, one of my favorite sayings was “Good judgment comes from experience, and experience comes from poor judgment.”  I've always had difficulty solidly learning new programming techniques in a traditional classroom.  The new techniques and theories I've learned don’t really take root until I've used them to solve

We started out in Episode 1 cleaning and standardizing data from the Academy.  As you recall, Mr. Vader apparently had a attitude when making his entry in the database.  The original data looked like this: You can find the code for creating the original data set back in Episode 1. There,
