6.5.2 Single Step Operation

    A single-step mode allows walking through a process flow on a step-by-step basis, examining the computed results and applying changes to parameter settings as necessary. If a graphical user interface is available, a confirmation dialog prompts the user before each step (Figure 6.5). The available choices are to start the next step, to continue in normal operation mode, and to stop the run.
