The program for this process, shown below, starts with two SNXT(09) instruc-
tions 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 start either
process A or process B. Both of the steps for these processes end with a
SNXT(09) that starts the step for process C.
