It is non-procedural, meaning that you state what you want. Regardless of the route, the one guarantee you have is that you never know how they did your shopping. They might go to the stock room directly since they know your product is yet to be stocked on shelves. You have no control over the clerk’s route. Method 2: Give the clerk your shopping list. In SAS, what you ask for is what you get (and how you get it). These languages were designed to mimic human behavior in processing paper forms. Programming languages like FORTRAN, BASIC, C, JAVA, COBOL and SAS have files with records stored sequentially-so processing happens one record at a time.
It is procedural, meaning that you write a procedure for what you need. Method 1: Go directly to the aisles for your products, you may have to ask around to get to the right shelf, but you know exactly where you are going and how you are going to get there. What is the difference between the DATA Step and PROC SQL? In this blog post I will answer a question posed by a student when I taught the SAS SQL 1: Essentials course. I’m sure you can now relate to Stephen’s answer. Welcome to the programmer’s world where everything depends on your need. Have you ever wondered why sometimes things appear grey? It puzzled me, as I just couldn’t fathom why things weren’t black or white. Going to my manager Stephen Keelan (who happens to be one of the most enabling managers I’ve ever worked with) with my SAS questions, brought the inevitable response of “It depends.” The questions I asked would make even the most seasoned programmer blush a beetroot red! Those were an intense nine months-I’ll tell you more in a later post about the learning system at SAS Institute which is simply world class.
When I joined SAS Institute I had no knowledge of SAS.
