File redirection

Learn what file redirection is and how it can be used.

File redirection refers to using overrides to change the file name and library or the type of the file you process. For example, you can substitute:

• One tape file for another tape file.
• One diskette file for another diskette file.
• Or change from using a tape or diskette file to using a display file, printer file, ICF file and so on.

System code might or might not support file redirection. See Recognizing Commands that Ignore or Restrict Overrides for rules on how system code processes overrides.
