from-file members are copied because no existing data will be destroyed. Each<br />
member that is copied is identified by a normal copy completion message. If the<br />
to-file is spooled, an empty spooled file is produced for each empty from-file<br />
member. If the PRINT parameter on the CPYF command specifies *COPIED,<br />
*EXCLD, or *ERROR, the empty members are shown in the lists, and no records<br />
are printed.<br />
Except for the CPYFRMQRYF command, an empty from-file member is never<br />
copied to a diskette or tape file, or to a physical file when MBROPT(*REPLACE) is<br />
specified. Empty from-file members are skipped for these types of to-files, and a<br />
CPF2869 message is sent (as either an informational or diagnostic message) to<br />
identify each empty member. The empty members are skipped to avoid destroying<br />
existing data. When an empty from-file member is skipped, the following<br />
considerations apply:<br />
v A tape or diskette file is not produced on the output volume. If the diskette file<br />
is spooled, no spool output file is created.<br />
v An existing to-file physical file member is not cleared.<br />
v If the to-file does not exist and you specified CRTFILE(*YES) on a copy<br />
command, a physical file is created.<br />
v If the to-file is a physical file and the to-file member does not exist, a member is<br />
added to the file.<br />
v If the PRINT parameter on the CPYF command specifies *COPIED, *EXCLD, or<br />
*ERROR, the empty members are not shown in the lists.<br />
When the copy command specifies a generic name or *ALL for the FROMMBR<br />
parameter, each empty from-file member skipped is identified by message<br />
CPF2869, sent as an informational message. If all the from-file members are<br />
skipped, a CPF2870 diagnostic message is sent after all the CPF2869 informational<br />
messages, followed by a CPF2817 escape message.<br />
When the copy command specifies a single member name or FROMMBR(*FIRST),<br />
or when there is an override for the from-file that forces a single member to be<br />
processed, an empty member that is skipped is identified by the diagnostic<br />
message CPF2869. The CPF2869 diagnostic message is followed by a CPF2817<br />
escape message.<br />
In the following example, the from-file and to-file are both database files, and<br />
EMPTY1 and EMPTY2 are empty members in the from-file.<br />
