Using overrides
You can use overrides to make temporary changes to file attributes and minor changes in how a program functions.
You can use overrides to temporarily change a file name, a device name associated with the file, or some of the other attributes of a file. Overrides allow you to select the data, on which they operate, without recompiling the program.
Note: When using overrides, the Open scope parameter (OPNSCOPE) should be
set to *JOB .
