CPF
CPF5813 File already exists
Most common cause
CRTPF, CRTLF or CRTSRCPF with the name of a file already in the library.
Other causes
- An install CL is run again without checking what it already created.
How to fix it
If re-creating is intended, delete the file first (mind the data). In CL use CHKOBJ before creating, or MONMSG CPF5813 if it existing is fine.
