ECHO, NOECHO
    

Controls whether or not commands in an Exec are displayed in the Session window. By default, NOECHO is in effect.

When you EXECUTE a file, the commands are not printed (echoed) on the output. Only output and the comments on NOTE commands will be printed. Comments after the # symbol will not be printed. When you want to turn on echo printing of commands use ECHO.

You can type ECHO and NOECHO in the session window before you invoke a macro or place them anywhere within the body of a macro. You can use ECHO and NOECHO several times in a macro to turn echo display on and off.
