Chains and Constellations
There are a number of commands that allow you to control the definition and graphical display of chain and constellation objects. For most commands associated with these objects, the actual command name is Chains. The generic structure of most Chains commands is:
Chains <ObjectPath> {ChainsOption} <Parameters>
or for commands that return information:
Chains_R <ObjectPath> {ChainsOption} <Parameters>
In either case, the {ChainsOption} indicates the action being executed by the command, and will change depending on the action you wish to take. Additional <Parameters> may be required depending on the {ChainsOption} specified.
If you use the Unload command to remove an object that is used by more than one chain or constellation, calculations to the other object will be affected.
