                                    ECHO
 
Displays or hides the text in batch programs when the program is running.
Also indicates whether the command-echoing feature is on or off.
 
When you run a batch program, MS-DOS typically displays (echoes) the batch
program's commands on the screen. You can turn this feature on or off by
using the ECHO command.
 
Syntax
 
    ECHO [ON|OFF]
 
To use the echo command to display a message, use the following syntax:
 
    echo [message]
 
Parameters
 
ON|OFF
    Specifies whether to turn the command-echoing feature on or off. To
    display the current ECHO setting, use the ECHO command without a
    parameter.
 
message
    Specifies text you want MS-DOS to display on the screen.
 
Related Command
 
For information about suspending the execution of a batch program, see the
<PAUSE> command.

                                ECHO--Notes
 
Using a message with the ECHO command
 
The ECHO message command is useful when ECHO is off. To display a message
that is several lines long without displaying other commands, you can
include several ECHO message commands after the ECHO OFF command in your
batch program.
 
Hiding the command prompt
 
If you use the ECHO OFF command on the command line, the command prompt does
not appear on your screen. To redisplay the command prompt, type ECHO ON.
 
Preventing MS-DOS from echoing a line
 
You can insert an at sign (@) in front of a command in a batch program to
prevent MS-DOS from echoing that line.
 
Echoing a blank line
 
To echo a blank line on the screen, you can type ECHO and then a period
(ECHO.). There must be no intervening space.
 
Displaying pipes and redirection characters
 
You cannot display a pipe (|) or redirection character (< or >) by using the
ECHO command.
                                      ***

                               ECHO--Examples
 
The following example shows a batch program that includes a three-line
message preceded and followed by a blank line:
 
    echo off
    echo.
    echo This batch program
    echo formats and checks
    echo new disks
    echo.
 
If you want to turn ECHO off and you do not want to echo the ECHO command
itself, include an at sign (@) before the command, as follows:
 
    @echo off
 
You can use the IF and ECHO commands on the same command line, as follows:
 
    if exist *.rpt echo The report has arrived.
 
                                      ***
