When you create a database file, you can name the file and the
member with the FILE and MBR parameters.
You name a file with the FILE parameter in the create command. You also
name the library where the file is stored. When you create a physical or logical
file, the system normally creates a member with the same name as the file.
You can, however, specify a member name with the MBR parameter in the create
command. You can also choose not to create any members by specifying
MBR(*NONE) in the create command.
Note: The system does not automatically
create a member for a source physical file.
