NONADDR or NONADDRESSABLE removes definitions from the address list.

There are 13 definition types that have been predefined as ‘Addressable’, meaning that you can ‘address’ a symbol on a diagram with them (select any symbol, and then click Dictionary > Addresses > definition type). Definition types specified as ‘Addressable’ are generally things like requirements, rules, test plans, and so on; things that the symbol on the diagram is ‘addressing’ or satisfying. To remove any one of those definitions from the Dictionary, Addresses drop-down menu, modify the statement in USRPROPS.TXT.
