New field in subfile display will not displaying on the screen.

[chuckw0325]

Working in COBOL 400. I have a display file that has a size defined as DSPSIZ(24 80 *DS3). The subfile that is being displayed currently the last field going to character 75. I'm trying to add a new field that is 3 characters in length to the end starting at value 78. This should work but for some reason, it will not display. Any guidance would be greatly appreciated.

How did you try to add the new field? Using SDA or editing the display file source?
