Valid Expression and Statement Groups by Field

When running a simulation, expressions and statements are either evaluated 1) once at translation (before initialization logic and before any events are created) or 2) continuously during the simulation run. The following chart categorizes the edit fields in this manner and shows the expression and statement groups that can be used in each field. Fields are classified as either expression fields or logic fields. Fields not listed on this chart are either menu fields or expression fields that accept only numbers.
