Composite flows with branches and recombination
The single flow format is the fundamental style in process transfer control. Only single flow is sufficient in sequence
control for simple operations. When various input conditions and operator manipulations intervene, however,
complicated conditions can be easily handled by using selective branches and parallel branches.
A branch for selectively processing many processes depending on a condition is called selective branch. A branch for
processing many processes at the same time is called parallel branch.
1. Selective branch
Either one among many flows is selected and executed.
2. Parallel branch
All of many flows are executed at the same time.
