If you add new symbols to an encyclopedia in USRPROPS.TXT, you must specify what definition type they are associated with by using the ASSIGN keyword.
If a new symbol specified in USRPROPS.TXT is missing this clause, System Architect gives a warning when opening the encyclopedia, and defaults to the null definition for the symbol, which consists only of the Description property.
SYMBOL "My Symbol" { DEFINED BY " My Definition" ASSIGN TO "My Diagram" }
Example
The following example defines the “Satellite” symbol type to be defined by the “Satellite” definition type (the fact that they share the same name is not enough).
Rename Diagram "User 1" TO "Wireless Network" Rename Symbol "User 1" TO "Satellite" Rename Definition "User 1" TO "Satellite" SYMBOL "Satellite" { DEFINED BY "Satellite" ASSIGN To "Wireless Network" }
