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

       revoutput - Reverse output strings sample extension

       @load "revoutput"

       BEGIN { REVOUT = 1 }    # Reverse all output strings

       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.

       @load "revoutput"

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

       The output from this program is:

       dlrow ,olleh
