The OS/400 system provides for the use of input and output spooling functions. Each OS/400 file description contains a spool attribute that determines whether spooling is used for the file at run time. The ILE COBOL program is not aware that spooling is being used. The actual physical device from which a file is read or to which the file is written is determined by the spool reader or the spool writer. See the Data Management guide for more information.
