(2) Structuring by dividing into multiple files
A program is stored in a file.
Changing the file name allows the CPU module to store multiple programs.
File name: PARAM

Dividing into multiple files according to the processes or functions enables simultaneous programming by two or
more designers. Managing the files separately eases reuse and utilization to other programs.
Structured programming is efficient in this way because only the corresponding file needs to be modified or
debugged in case of change in the specifications.
(a) Dividing into multiple files according to the processes
Processing contents
are divided according
to the processes.
