| They aren't. Those are terms relating to COBOL programs. |

Hi Mayos,
1. A COPYBOOK can contain some portion of your COBOL program.
For instance you have two programs: prog1 and prog2.
Both of these use a same set of working storage variables. Here, instead of using them twice in both programs, you can make a COPYBOOK ie another pgm/dataset letz say "progcpy", wch will only contain these working storage variables and nothing else.
This is called a working storage cpybook. You can incluse this "progcpy" in both of your pgms by using the statement:
====prgcpy====
05 working_variable1
05 working_variable2
05 working_variable3
============
prog1
UNEXPANDED: - progcpy
prog2
UNEXPANDED: - progcpy
2. A COPYLIB is the one where, after compiling your programs, the copy of it is picked up by the CICS scrn.
