fileDialog.show();
// Get and set the String file project name
newProj = fileDialog.getFile();
System.out.println("File Name :" + newProj);
// Open or create a random access file
raf = new RandomAccessFile("c:/"+newProj+".kss", "rw");
randomAccssFile = "c:/"+newProj+".kss";
}

System.out.print("Error: " + ex);
System.exit(0);
}
