You can use the CREATE STATIC keyword, and the class name as the only 
instance. 

Note that it won't prevent anyone else to instanciate the class. An example of 
that is the Setting class in the gb.settings component.

If you really want to prevent the instanciation, you can put that in the 
constructor:

PUBLIC SUB _new()

  IF Class[Object.Type(ME)].Count > 1 then Error.Raise("Singleton class")

END
