gawk: User-defined

 
 9.2 User-Defined Functions
 ==========================
 
 Complicated 'awk' programs can often be simplified by defining your own
 functions.  User-defined functions can be called just like built-in ones
 (Function Calls), but it is up to you to define them (i.e., to
 tell 'awk' what they should do).
