For database files, you first specify a generic name on the FROMMBR or FROMLABEL parameter. You then modify the generic name to indicate the starting character string that each member or label has in common, and then follow it with an * (asterisk).
For example, if you specified FROMMBR(ORD*), the copy command would copy all database members that start with ORD.
Note: 
If you copy a generic set from a diskette, and a label that
is being copied continues on another diskette volume, then the copy command
copies all the affected labels on the continuation volume. This is also true
when you copy all labels.
