cpyf copy file member is to copy file content to an existing
file. If file does not exist then user can create a new
file. The structure will be based on source file.
crtdupobj create duplicate object, create clone exactly as the
source file with structure and content with its link to prgram
and logical file and its authority setting as well. no need to
recompile pgm that use this file.

cpyf command is to be used when you want to copy the data
of the file. For eg. if want a selection of data that can
be done. It is not necessary that from file and to file
record format are exactly same
In case of crtduobj, a clone of the object is created.

CPYF command are used to copy the all data from one data
base file to another or copy the required data from one
file to another files .
when we copy the data from one file to another file that
time if user want to create new file then create new file

Answer / shikha
Copy File (CPYF) command could be used to copy the source
into a database file.
(CRTDUPOBJ) command to create a copy of an existing object.
The duplicate object has the same object type and
authorization as the original object and is created into
the same auxiliary storage pool (ASP) as the original
object. The user who issues the command owns the
duplicate object.
If you create a duplicate object of a journaled file, the
duplicate object (file) will not have journaling active.
However, you can select this object for journaling
later. If you create a duplicate object and the object
(file) has no members, the last used date field is blank
and the count for number of days used is zero.
