Java AWK Function syntax
Hi, I would like to know what is the correct syntax to perform a function in awk. Although I have seen several examples, not get it to work, this is what I'm trying:

Code:
#!/bin/bash

awk

function multi (number) {
  return number * 3
}
print multi (4)

Thanks

__________________________________________________________________________________________________________________________________________________

NAME

       fileutil::multi - Multi-file operation, scatter/gather, standard object

SYNOPSIS

       package require Tcl  8.4

       package require fileutil::multi	?0.1?

       package require fileutil::multi::op  ?0.1?

       package require wip  ?1.0?

       ::fileutil::multi ?word...?

_________________________________________________________________

DESCRIPTION

       This  package provides a single command to perform actions on multiple files selected by glob patterns. It is a thin layer over the package
       fileutil::multi::op which provides objects for the same. This package simply creates a single such object and directs all file commands	to
       it.

       At the core is a domain specific language allowing the easy specification of multi-file copy and/or move and/or deletion operations. Alter-
       nate names would be scatter/gather processor, or maybe even assembler.  For the detailed specification  of  this  language,  and  examples,
       please see the documention for the package fileutil::multi::op.

PUBLIC API

       The main command of the package is:

       ::fileutil::multi ?word...?
	      This command interprets the specified words as file commands to execute. See the section FILE API of the documentation for the pack-
	      age fileutil::multi::op for the set of acceptable commands, their syntax, and semantics.

	      The result of the command is the result generated by the last file command it executed.

BUGS, IDEAS, FEEDBACK
       This document, and the package it describes, will undoubtedly contain bugs and other problems.  Please report such in the category fileutil
       of the Tcllib SF Trackers [http://sourceforge.net/tracker/?group_id=12883].  Please also report any ideas for enhancements you may have for
       either package and/or documentation.
