CPF
CPF2103 Library already in the library list
Most common cause
ADDLIBLE of a library that is already in the list. Harmless in itself, but without MONMSG it makes the CL fail.
Other causes
- The CL is called several times in the same job, and adds the same library each time.
How to fix it
Put MONMSG CPF2103 right after ADDLIBLE. If the library must be in a specific position, remove it with RMVLIBLE and add it again.
