These are a group of commands that affect the current model state. Thus, unlike with most commands that are specific to a model component (i.e., a data scalar or a geometry set), many model commands act on the entire model. For instance, the entire model state is reset with the model new command and is saved/restored with the model save and model restore commands. These commands differ from the program commands where the results are not saved with the model state but are generally stored in the computer registry.
