A string argument is used to indicate the reason for successful termination, which can be reported back to the user in some appropriate way by the simulation tool. Terminate is most commonly used to give a more appropriate stopping criteria for terminating a simulation than a fixed point in time.&lt;/p>&lt;/body>&lt;/html></Text>
