Reading database records using an arrival sequence access path
These read operations are allowed if the file is defined with an arrival sequence access path, or if the file is defined with a keyed sequence access path, but you choose to ignore the keyed sequence access path.
Note: The system performs the read operations based on the operations that
you specify using your high-level language. Your high-level language might
not allow all of the following read operations. See your high-level language
topic collection to determine which operations are allowed.
