For Progress OpenEdge, there's two ways to change the field's screen value - either display something on the field, or set the field's "SCREEN-VALUE" attribute, like so:

DEFINE VARIABLE chField AS CHARACTER   NO-UNDO.

DEFINE FRAME f-demo
   chField FORMAT "X(10)"
   WITH OVERLAY TITLE "Demo Frame".

ON VALUE-CHANGED OF chField
   DO:

       /* Moves data from the screen field to the variable     */

   ASSIGN chField.

       /* Upper Case the field     */

   ASSIGN chField = CAPS(chField).

       /* One way to change the screen value     */

   DISPLAY chField WITH FRAME f-demo.

       /* Another way to change the screen value */

   ASSIGN chField:SCREEN-VALUE = chField.

   END.

   /* Activate the input   */

UPDATE chField WITH FRAME f-demo.

If this doesn't answer your question, you'll need to clarify what you're looking for.
