Autoexec.bat help

Question

I've recently purchased a book called "Object-Oriented Programming With JAVA Second Edition" by Barry J. Holmes and Daniel T. Joyce. I've downloaded and installed version 1.2.2 of java because that is what the book refers to. That's no problem. I've also installed the avi package that came on cd with the book, that went well except for one thing, it asked me to edit my autoexec.bat file to tell the PC how to interact the two programs. I have no idea how to do this, although I do know where my autoexec.bat file is. This is what I have now:
SET PATH=%PATH%;C:\PROGRA~1\COMMON~1\AUTODE~1
This is what it says I need to have:
@C:\PROGRA~1\NORTON~1\NAVDX.EXE /Startup
set CLASSPATH=.;c:\
path=c:\jdk1.2.2\bin
Here's the instructions given to me:
Now that the SDK and the AVI package has been installed on your computer, you must set up your computer so that these programs can be located when needed. Use the NotePad utility to open the autoexec.bat file that is stored on your C drive. Amend the file to include the jdk1.1.2 directory in the path entry. Also include a CLASSPATH entry. The following listing of an autoexec.bat file illustrates how the path and CLASSPATH entries have been modified to include jdk1.2.2 and the avi package.
@C:\PROGRA~1\NORTON~1\NAVDX.EXE /Startup
set CLASSPATH=.;c:\
path=c:\jdk1.2.2\bin
The interpretation of the CLASSPATH entry follows. The pathways are separated by the semicolon, hence there are two pathways the computer should use when searching for the named packages. The first pathway is signified by the use of a period . which implies the current directory. The computer will search all subdirectories of the current subdirectory to find the subdirectory of the avi package.
The second pathway is signified by c:\ which is the root directory of the C drive. The computer will search all the subdirectories of the root directory to find the subdirectory of the avi package. If you use software that also requires a CLASSPATH entry, append the entry to the one shown here. Separate the entries with a semicolon, and only set the CLASSPATH once.
The path entry signifies where on the C drive the computer can find the Java development environment. Once again, if you use software that requires a path entry, append the entry to the one shown here, separating different pathnames by a semicolon.
Save the modified autoexec.bat file, and finally restart your computer.
Please help me.
Also, I'm new to this site, if there was a better place to post this, please let me know. Thanks.

thanks guys, it now works but I'm getting a strange error for the test code, here's the test code I was using:
// program to write the text literal "HELLO WORLD" centrally on the screen
import avi.*;
class Example_1
     public static void main(string[] args)
     // create a window object screen
     Window screen = new Window("Example_1.java","bold","red",72);
     screen.showWindow();
     screen.write("\\n\\n\\n\tab\tab\tab HELLO WORLD!");
The error it was giving me was:
class string not found on line 7 and it had a pointer looking at the 'm' in the "public static void main(string[] args) line. I did this in the command console using 'javac Example_1.java' command. Am I missing something?, or should I just start using something else? I've done C++ but this has me boggled.
