Vensim Help

A Venapp screen typically has controls and comments that are not visible when the Venapp is running.  For example, there might be a  command to load a model.  In addition to this the order in which controls are defined is important in determining the operation of the Venapp with the user presses the Tab key.  

The screen definition dialog described below allows you to edit everything in the screen - including what is visible.  To open this dialog you can select the View>Screen Definition command from the menu, click on the Screen Definition button appearing at the bottom or use the right mouse button to click on the screen at any position off of a visible control.
