Eval tags

Eval tags are objects that acquire values on the basis of the defined expression (formula). Maintainer of eval tags is the calculation process - SELF.CLC. This process determines values of eval tags and reports changes of these values to D2000 system. Value changes are reported via communication with process D2000 Server.
