By default, each line in a batch file is displayed or "echoed" as it is executed. You can change this behavior, if you want, in several different ways:
|Any batch file line that begins with an @ symbol will not be displayed.|
|The default setting can be changed with the SETDOS /V command, or the Default Batch Echo configuration option.|
For example, the following line turns off echoing inside a batch file. The @ symbol keeps the batch file from displaying the ECHO OFF command itself:
TCC also has a command line echo that is unrelated to the batch file echo setting. See ECHO for details about both settings.
