Customizing File Manager to use a scrambling exit

You can use File Manager to create test data based upon production data with the option to change the values of certain fields that may contain sensitive information. This facility is known as field scrambling.

You can also write your own scrambling exit, to perform scrambling operations that are not provided in File Manager.

To specify a scrambling exit, select Scramble Type 4 ("Exit") from the Field Attributes panel of the template editing process, where you have specified the fields to be scrambled. File Manager displays the Scramble Exit Specification panel where you can provide the exit name, a constant to be passed to the exit, and specify whether numeric fields are to be formatted before the value is passed to the exit. The exit can be an assembler or LE-enabled program. The File Manager for z/OS User’s Guide and Reference describes how to use the scrambling exit.
