The following diagram demonstrates the flow of processing and the switches
that are used for execution control.
The program for this process, shown below, utilizes the most basic type of step
programming: each step is completed by a unique SNXT(009) that starts the
next step. Each step starts when the switch that indicates the previous step has
been completed turns ON.
