The screen graph is displayed by pressing the <br /> "S" key (without the quotes) . <br /> After inspection of the graph, you can continue by pressing any key. The <br /> graph will be cleared from the screen, and the message shown above will be <br /> displayed again. <br /> DODSON & ASSOCIATES, INC. THE DODSON HYDRAULICS LIBRARY, PAGE 7 <br />
