Answer / asad
A copybook is a section of code written in assembly
language or a high-level programming language that can be
copied (from a master) and inserted into several different
programs (or multiple places in a single program). It is
often used to define the physical layout of program data,
pieces of procedural code and prototypes.
The term “copybook” may have originated from use of COBOL
on IBM mainframe operating systems: COPY is the COBOL
keyword for this, and the master item was stored as
a “book” within a larger library of source code.[1]
Major reasons for using COPYBOOKs in assembly language or
COBOL are to:
ensure that everyone uses the same version of a data layout
definition or procedural code.
make it easier to cross reference where components are used
in a system.
make it easier to change programs when needed (only one
master copy to change).
save programmer time by not needing to code extensive data
layouts (minor, but useful).

Answer / kumaran
copy book is nothing but it is a common library where one
or more persons can share the same data type it can be used
in cobol cics db2 and its main function is to use in the
db2 for declaring data types beyond that it acts as a back
up for the program so the programmers can use it different
times without andy change...
