Visual Logic Instructions and Assignments
Visual Logic can be installed from the CD that accompanies our textbook. It is a nifty tool for creating program flowcharts, but that is only half of the story. Until this software came along, flowcharts were static diagrams that outlined the flow of execution of a computer program. When a Visual Logic flowchart is done, you can run the program
“behind” the flowchart. This is a great learning resource for budding programmers.
You can even create interactive programs that allow the user to input values for variables at runtime. Visual Logic is a terrific tool for grasping basic programming concepts such as variables, operators, expressions, branching, and looping. It is excellent preparation for more sophisticated programming with Visual Basic.NET. We hope you like it!
Install Visual Logic on your home PC by accepting all defaults in the installation wizard.
Then, put the CD away in a safe place.
Once installed, Visual Logic can be started in the usual way from the Windows Start menu. On the “splash screen” shown here, click on “Continue” to produce the starting flowchart. The starting flowchart displays a “Begin” and “End” symbol as shown. To create a flowchart, you add symbols between these starting symbols. Lesson One : Sample Visual Logic Program
( perform the actions that are in boldface )
Hover your mouse over the red arrow between the Begin and
End symbols. It will turn green, indicating that you can click on it to get a popup window. This popup window has the other symbols we will need to create programs.
Click on the green arrow and select the Output symbol.
This inserts the Output symbol into the flowchart as shown. The Output symbol produces output on the display screen. Next, we will specify what the program should output.
Double click on the Output symbol to get the
Output dialog box.
Output that consists of a text message must be enclosed in quotes. This is called a string.

    Logic models are typically diagrams, flow sheets, or some other type of visual schematic that conveys relationships between contextual factors and programmatic inputs, processes, and outcomes. Logic models can come in all shapes and sizes: boxes with connecting lines that are read from left to right (or top to bottom); circular loops with arrows going in or out; or other visual metaphors and devices. What these schemata have in common are they attempt to show the links in a chain of reasoning about "what causes what," in relationship to the desired outcome or goal. The desired outcome or goal is usually shown as the last link in the model.…
