Basics Hy-Phy is very feature rich, as its primary purpose was to serve as the authors' research tool. Therefore, there are many features that most users will never implement. In fact, many, if not most users, will rely almost totally on prewritten Hy-Phy "batch files" (lines of code that Hy-Phy interprets, much like a SAS program). To introduce the major components of the Hy-Phy language, we will first step through some very basic batch files so that the core batch file elements are described.
