It's more an illustration of legacy designs that didn't stand up well but 
a short was originally used in our code for object numbers. Gotta save 
bytes. Who ever thought there would be more than 32k objects? 

Changing it to unsigned short bought us time. Going to an int would have 
had repercussions because of those bytes a diligent programmer saved back 
in the '90s.
