Backup programming techniques

The programming techniques include recovering jobs, displaying status messages, and redirecting output from save and restore commands to an output file.

Considerations for job recovery
Job recovery and starting again should be a basic part of application design. Applications should be designed to handle.
Information in output files
Most save commands create output that shows what the system saved. Depending on which command you use, you can direct this output to a printer (OUTPUT(*PRINT)), a database file (OUTPUT(*OUTFILE)), a stream file, or a user space.
Interpreting output from save (SAV) and restore (RST)
When you use the Save (SAV) command or the Restore (RST) command, you can direct output to a stream file or to a user space.
Interpreting output from save commands
You can use these save commands or APIs to direct output to an output file.
Retrieving the device name from save completion messages
The CL program retrieves the device name from the CPC3701 message (found in positions 126 through 135 of the message data) and uses the information to determine which device is used by the next save command.
Displaying status messages when saving
This program sends a message to the external (*EXT) program message queue if any objects cannot be saved.
