A running screen comes up transiently during a simulation, showing the results as they unfold, and then disappears. This can be an effective visual device for displaying information in two formats — such as time graphs and Gantt charts. A running screen is very similar to an Anykey screen, except that you don't need a key stroke. The last two controls in the screen must be a COMMAND control asking for a simulation, and a CLEARSCREEN control telling which screen to shift to at the end of the simulation.
