Problem:

To be able to control a ListView via the keyboard you need to set focus on the control.  Is there a way of doing this?

Resolution:

Unfortunately the Dialog System SET-FOCUS function does not work with ListView controls.  So, it is necessary to look at the control program and add the following code:

...

PROCEDURE DIVISION.

...

   when "SET-FOCUS"

      invoke Object-Reference "SetFocus"

         ...

This new function is then called from the screenset via the following code:

...

          SET OBJECT-REFERENCE(1)  LVIEW

MOVE "SET-FOCUS" call-function(1)

CALLOUT "lviewctl" 3 $NULL

...

Functions can also be added for hiding and showing the ListView control if required.
