Clear dos windows

Posted by Erich Meuse on June 20, 2001 at 4:17 PM

From win95 I found the following code works:

Make sure ANSI.SYS is loaded from the config.sys file.
If the following line does not exist in the config.sys file
then you will have to add it and reboot your system before
the driver will be loaded.


Java code:

char esc = 27; // ESC code
String clear = esc + "[2J" // note case
System.out.print(clear); // Dos screen should be cleared
