A new feature on the SAS support site makes it easier to look up SAS syntax. This is the SAS 9.3 Syntax Index, which lists the important keywords of SAS so that you can quickly look up the syntax models and rules you need.
You have to know the name of the statement, function, option, or other SAS feature to look it up, though often it is easy enough to guess. Let’s say you’re hoping to find a function to compute the distance between U.S. ZIP codes. Maybe the name starts with ZIP. In the SAS 9.3 Syntax Index, click the letter Z, scroll down till you get to ZIP, and you find, among other things, “ZIPCITYDISTANCE function.” Is that the function you want? Click the list item, and the syntax entry appears in the right side of the window.
