BLOX maintains an image of all the classes currently defined. When you modify classes or their methods, the memory image is changed, but not the permanent image on disk. To make this happen, choose ``Save image'' from the File menu. It will replace the gst.im file in your directory. (BLOX will ask whether to save the image when you exit the program.)
It's a good idea to save the image early and often. BLOX is not entirely stable, and if it crashes, you'll lose all the work you've done since you last saved the image. It entered an infinite loop once as I was writing this, and it could happen to you.
When you want to submit your assignment solutions, you will want to export a file representing all the information about the class. To do this, select the class in the class browser, and then choose ``File out...'' from the Class menu. This generates a small ASCII file containing the code underlying the class definition.
