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

Up: String Functions ... In awk, the ‘*’ operator can match the null string. This is particularly important for the sub, gsub, and gensub functions. For example:

section User-Defined Functions, describes how to write your own @command{awk} functions. Writing functions is important, because it allows you to encapsulate algorithms and program tasks in a single place. It simplifies programming, making program development more manageable, and making programs more readable.

The functions in this section look at or change the text of one or more strings. Optional parameters are enclosed in square brackets ([ ]). Those functions that are specific to gawk are marked with a pound sign (`#'): ... Note: In older versions of awk, the length function could be called without any parentheses.
