A COBOL source program must be identified, it must specify linkage between the computer system
and the data files to be processed, it must define the data to be processed, and finally it must specify
how the data is to be processed. A COBOL source program consists of the information required to
perform these functions organized into the four required divisions.
Identification Division contains the information that identifies the program. At the very least, this
division states the program name. In addition, it may contain the date the program was written, the
date compiled, the author, the installation, and any remarks that might be useful to someone
reading the program.
