If you are not concerned about platform independence, which your question seems to imply (since you are talking about MS-DOS boxes), why not just call a native method that does your trusty old C++ clrscr()? To figure out how to do this, look for documentation at java.sun.com on JNI. I don't have anything significant about JNI here at artima.com, so I'd just do a search at java.sun.com for JNI (Java Native Interface). bv
