What are UDG's and how can I use them?
UDG's are user defined graphics, i.e. characters of which you can completely determine the shape yourself.  
There are 8 of these, and they have character codes 0 to 7. See the OPL-Reference for details.  
An important point to consider is that on the older CM/XP organisers (before version 2.6) the UDG shapes are lost every time the Psion is switched off. Therefore the automatic timeout must be avoided, otherwise you have to redefine the UDG shapes when the organiser switches on again. The LZ does not have this problem.
Another important thing to be aware of is that if a UDG is redefined, all instances of that UDG character already on the screen are immediately changed as well (this feature can be used to display small animations).
