Here is the code.

ThisForm.txtProcessDisplay.value = "Building road inventory records"
ThisForm.txtProcessDisplay.refresh

SELECT *
FROM plc,lne;
WHERE lne_placement_id = plc_placement_id ;
AND lne_survey_id $ ThisForm.cSurveyString ;
AND SUBSTR(lne_lane_number,1,1) $ 'RL' ;
AND !lne_unable_to_rate ;
AND !lne_unsafe_to_rate ;
ORDER BY lne_placement_id, lne_lane_number;
INTO TABLE data\pmi_inventory;
DATABASE data\pmib;
NAME pmi_inventory

The textbox object is not refreshed until after the SQL statement finishes.
I have tried both using a refresh on the textbox alone and the whole form.
Same results, no refresh until after the SQL executes.
