Output spooling is valid for batch or interactive jobs. The description of the file that is specified in the RPG program by the file name contains the specification for spooling as shown in the following diagram:
File override commands can be used at run time to override the spooling options specified in the file description, such as the number of copies to be printed. In addition, i5/OS spooling support allows you to redirect a file after the program has run. You can direct the same printed output to a different device such as a diskette.
