4GL Q: Popup window from within Construct statement

Fellow Informix'ers, A question on the construct statement in 4GL. I am creating the where clause of a select using construct, but when the cursor goes to a particular field, I want to throw up a window and let the user select one of the available values. How would I do this from within construct? From within INPUT ARRAY, I can do this using the ON KEY and the INFIELD() function, figure out which field the cursor is on, and throw up a Window and let the user pick one value from a list. Is it possible to achieve the same functionality from within a construct statement? Any and all responses appreciated.
