Example (3) Parallel branch/join control of processes
● This program starts multiple processes at the same time. When the work is completed in
each of the branched processes, they merge again before transferring execution to the next
process.
● In the program, write multiple process transfer instructions for one execution condition in
succession in a process.
● To merge processes, include a flag indicating the state of the other processes in the transfer
condition for the next process. When they merge and execute the next process, clear all
uncleared processes at the same time.
