NAME

6       revoutput - Reverse output strings sample extension
7

SYNOPSIS

9       @load "revoutput"
10
11       BEGIN { REVOUT = 1 }    # Reverse all output strings
12

DESCRIPTION

14       The  revoutput extension adds a simple output wrapper that reverses the
15       characters in each output line.  It's main purpose is to  show  how  to
16       write  an  output  wrapper,  although  it may be mildly amusing for the
17       unwary.
18

EXAMPLE

20       @load "revoutput"

23           REVOUT = 1
24           print "hello, world" > "/dev/stdout"
25       }
26
27       The output from this program is:
28
29       dlrow ,olleh
