   To keep the shell doing what you want, consider creating a subdirectory in
your home directory called, for example, shell-scripts. In this directory
write a three-line script for your java apps and others you want to invoke
from an icon or menu. Make the script executable (e.g., 'chmod 755
treeform.sh'), then call the script from your icon.

   The treeform.sh script would look like this:

cd Software/TreeForm102
java -jar TreeForm.jar
cd

   When run, the PWD will change to the Software/TreeForm102 directory, then
invoke the java application from within that directory. When you exit, the
PWD returns to your home directory.
