Copybook is a bunch of source code statements.
Lets take an example:
I have around 100 programs which are doing addition for two numbers.
Now in this scenario I can write logic of adding two numbers but instead of writing same code in alll programs I can create a member and put the code for adding two numbers into it and just copy that member into the programs where I want to implement this logic.
The source of this copy book can be seen into the spool file of the program in which you ha ve included it.
let me know if you stilll need any more explanation.

Hi,
You use the compile time directive /COPY to add the source from another source member into your
program.
These days it would be more advisable to use a module instead of a copybook.
