Used to remove 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 choose Dictionary, Addresses, and then the 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.
