4. RESTORE the FILE in PROD status into a test version such as T001.
5. DEFINE the RECORD where you can change/add columns.
6. Then MODIFY the ELEMENT (put Y in the newly added columns and press PF9 Apply).
7. Run MODIFY FILE to change the record length/blocksize.
8. When done, run VERIFY FILE - if no errors then COPY FILE to PROD and ENABLE FILE.
9. RESTORE the DATAVIEW from PROD to a test version like T001.
10. Then COPY the DATAVIEW from test to PROD status.
