REVOUTPUT(3am)		   GNU Awk Extension Modules		REVOUTPUT(3am)

NAME
       revoutput - Reverse output strings sample extension

SYNOPSIS
       @load "revoutput"

       BEGIN { REVOUT =	1 }    # Reverse all output strings

DESCRIPTION
       The  revoutput extension	adds a simple output wrapper that reverses the
       characters in each output line.	It's main purpose is to	 show  how  to
       write  an output	wrapper, although it may be mildly amusing for the un-
       wary.

EXAMPLE
       @load "revoutput"

       BEGIN {
	   REVOUT = 1
	   print "hello, world"	> "/dev/stdout"
       }

       The output from this program is:

       dlrow ,olleh

BUGS
       This extension does not affect the default standard output.
