CLOSE statement. The file or device may then be reopened using the same or a different file number. A
CLOSE statement with no file number specified closes all open files and devices.
CLOSE statement sent to a file or device opened for sequential output writes the final buffer of output to that file or device.
This closes all open devices and files.
