File Management - IBM

copied from the from-file to the to-file, disregarding differences in record
formats (similar to the FMTOPT(*NOCHK) parameter option on the CPYF
command, except for the CCSIDs.)
CPYFRMQRYF
Copy from Query File copies an open query file to a database or device
file.
The system does not reclaim DDM conversations for a job when a copy command
produces an error.
Note: In releases prior to Version 3 Release 2, copy errors caused the Reclaim
Resources (RCLRSC) command to run, which also ran the Reclaim
Distributed Data Management Conversations (RCLDDMCNV) command.
Although the RCLRSC command still runs, it no longer runs the
RCLDDMCNV command when a copy error occurs.
If you specify a DDM file and a local file on the CPYF or CRYSRCF commands,
the system does not verify that the remote and local files are not the same file on
the source system. If you specify one DDM file, you can potentially copy to and
from the same file.
For information on how to copy DBCS-open fields to graphic fields (including the
option of removing trailing single-byte blanks for the DBCS-open field first), see
“DBCS-graphic fields using FMTOPT(*MAP) or FMTOPT(*NOCHK)” on page 115.
Throughout this topic, unless the text specifies a specific command, the term copy
commands refers to all the commands just described.
The device and database files where you can perform copy operations are shown
