The UCF/batch front end module (i.e., the program on the EXEC PGM= card for a UCF/batch job) is something which the user can configure.
This configuration includes a RETCD parameter which can be set to YES or NO.
NO results in the suppression of both of these non-zero return codes.
During the installation process, a default UCF/batch module called RHDCUCFB is created which defaults to RETCD=YES.
If you want to suppress these return codes, create your own version of a UCF/batch front end module
and specify RETCD=NO.
Note that the UCF/batch job will still see the 1469 error-status or the D902 abend code, but the return code will be zero.
