How about reading the fine manual.

       Syntactically, a rule consists of a pattern followed by an action.
    The action is enclosed in curly braces to separate it from the pattern.
    Newlines usually separate rules.  Therefore, an `awk' program looks
    like this:

         PATTERN { ACTION }
         PATTERN { ACTION }
         ...
