Reading a file multiple times (CLOSE command)

You can use the CLOSE command to process the records in the database file more than once. When the file is closed, the next RCVF command implicitly reopens the file and reads a record. You can also use the CLOSE command for a database file that is already closed or was never opened; no error message is sent. When the CL program or procedure ends, all database and display files that are implicitly opened within the CL program or procedure were implicitly closed.
