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 mildy amusing for the
       unwary.

EXAMPLE
       @load "revoutput"

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

       The output from this program is:

       dlrow ,olleh
