>In the appwiz class library there is a container class called wzapplication. It has a custom method called DoForm. TLNOSHOW is a parameter name for this method. I searched throughout the project and this is the only place I could find it. Since it's a parameter and since it's refered to in the code as a logical, it *should* always be defined. It will be .F. if the parameter isn't passed.
