Details

The viewer calls the model's _preterm method from the viewer's _preterm method. The viewer's _preterm method is called immediately before the frame SCL's term label runs.

If return-code is set to 0 by the model _preterm method, the viewer assumes that normal termination is allowed. If return-code is set to a nonzero value by the model _preterm method, the viewer assumes that normal termination is not allowed and sets status to resume. This means that the frame does not terminate but continues execution. For example, the model should not be configured to allow termination if there are data in error.
