In applet program mode, the program is initialised with the program's default settings. In application program mode, the settings that applied when the program was last closed are used, provided they were successfully stored in and retrieved from the urvstart.ini file. That file holds cube size, display colour values, option parameter settings and some program settings. If that file is not found, default values are used. In application program mode most of these settings can be changed on-line after start-up if desired.
