Details on Running JRG/Viewmat

On Windows, open a DOS or Command Prompt window, ``cd'' to the folder for this exercise, and enter: ``java -cp jrg.jar Viewmat''.
```
	cd c:\jrg
        java -cp jrg.jar Viewmat
```
On WindowsXP with Sun's J2SDK 1.4.1 installed, the commands would be:
```
	cd c:\jrg
	"C:\j2sdk1.4.1_01\jre\bin\java" -cp jrg.jar Viewmat
```
Note Viewmat with a capital V. The java commands are case-sensitive.
On Windows98 with Sun's JRE 1.2 installed, you have to run the commands:
```
	cd c:\jrg
	"c:\Program Files\JavaSoft\JRE\1.2\bin\java" -cp jrg.jar Viewmat
```
(Copy them from here in the browser and paste it into the DOS window using the paste button at the top of the window.) This adds the jrg.jar file to the ``classpath'', allowing Viewmat to use all the .class files without unpacking them from the .jar file.
On MacOS X, open the Terminal application, and use these commands to go to the folder you set up in your Home, and run JRG (also case-sensitive):
```
	cd ~/jrg
	java -cp jrg.jar Viewmat &
```
On MacOS 8-9, first unpack the jrg.jar file with the jar application included in the MRJ JDK package. Then you can drag the Viewmat.class icon in the onto the JBindery icon. Use Find File or Sherlock to locate JBindery within your installed MRJ JDK folders. Then click the Run button. Note that you can save a double-clickable application out of JBindery for Viewmat.
