The STEP command provides the most elementary way of advancing and suspending the execution. You need not define any breakpoints. As a reaction to this command, the model executes the specified number of steps, passing from its current configuration to another, where the execution is again suspended. The command is entered as follows:
If no number is specified, one step is taken.
In particular, you can start the proper run of the code by using STEP as the first execution command in the debugging sessions. As a result, the model enters its default configuration and performs all actions attached to the corresponding default transitions.
