revtwoway - Reverse strings sample two-way processor extension
cmd = "/magic/mirror"
print "hello, world" |& cmd
cmd |& getline result
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.
