Control Statements in Actions ============================= "Control statements", such as `if', `while', and so on, control the flow of execution in `awk' programs. Most of the control statements in `awk' are patterned on similar statements in C. All the control statements start with special keywords, such as `if' and `while', to distinguish them from simple expressions. Many control statements contain other statements. For example, the `if' statement contains another statement that may or may not be executed. The contained statement is called the "body". To include more than one statement in the body, group them into a single "compound statement" with curly braces, separating them with newlines or semicolons.
