There are two types of copybooks: 1. Working storage
copybook 2. Procedure division copybook
1. Working Storage copybook: It contains the input or
output fields names with the field definitions like type or
length of the fields. Instead of defining so many variables
in the WS section, we can have it in a separate file like
thing. It is also useful in mapping the I/P or O/P records
with the specific fields.
2. Procedure Division copybook: It contains set of COBOL
statements in order to execute it at a particular time. It
acts as a sub-program.
