The following process requires that a product is processed in one of two
ways, depending on its weight, before it is printed. The printing process is the
same regardless of which of the first processes is used. Various sensors are
positioned to signal when processes are to start and end.

The following diagram demonstrates the flow of processing and the switches
that are used for execution control. Here, either process A or process B is
used depending on the status of SW A1 and SW B1.

The program for this process, shown below, starts with two SNXT(09) in-
structions that start processes A and B. Because of the way 00001 (SW A1)
and 00002 (SB B1) are programmed, only one of these will be executed to
