>What is the procedure when you do not want the user to edit a control (text field), but you do want your program to change the values in the table associated with the control. When I set the control to READONLY = .t., I can not update the table with program code? Any ideas?

I'm assuming you have the field bound to the control. You could unbind the control from the field, then programmatically update the control.value when you update the field.
