NAME
       revtwoway - Reverse strings sample two-way processor extension

SYNOPSIS
       @load "revtwoway"

       BEGIN {
	   cmd = "/magic/mirror"
	   print "hello, world"	|& cmd
	   cmd |& getline result
	   print result
	   close(cmd)
       }

DESCRIPTION
       The  revtwoway  extension adds a	simple two-way processor that reverses
       the characters in each line sent	to it for reading back by the AWK pro-
       gram.   It's  main purpose is to	show how to write a two-way extension,
       although	it may also be mildly amusing.
