 7 Patterns, Actions, and Variables
 **********************************
 
 As you have already seen, each `awk' statement consists of a pattern
 with an associated action.  This major node describes how you build
 patterns and actions, what kinds of things you can do within actions,
 and `awk''s built-in variables.
 
    The pattern-action rules and the statements available for use within
 actions form the core of `awk' programming.  In a sense, everything
 covered up to here has been the foundation that programs are built on
 top of.  Now it's time to start building something useful.

 
* Pattern Overview            What goes into a pattern.
* Using Shell Variables       How to use shell variables with `awk'.
* Action Overview             What goes into an action.
* Statements                  Describes the various control statements in
                                 detail.
* Built-in Variables          Summarizes the built-in variables.
