Generally, There are 2 type of copybooks.
Data division copy book
These copybooks are usually used to represent the
structure of the file or variables used in Cobol. Say if
there are any changes in the layout of copybook. make sure
the length specified in JCL LRECL is appropriate.
Procedure division Copybook.
These copybooks will have some cobol stmts coded in them.
For this copybooks there can be no changes in JCL.

The only change would be to make sure the program is
compiled and link-edited, so as to get the changes
reflected in the load module you specify in the JCL.
