From line vertices are called anchor points. It snaps anchor points to 10-mile increments and orders anchor points in a clockwise direction. MetGen determines the states affected by a particular from line and labels each one in the display. Via the graphics, the user can toggle off state labels to remove those states from the list.

Objects interact by sending each other messages.
An object's behavior, the list of messages it recognizes, is defined by the object's class. In the computer science sense, a process is a program - a separate and distinct piece of executable code. Since it is often desired that processes interact, the operating system provides mechanisms for processes to communicate with each other. WFO-Advanced uses these mechanisms to provide higher level abstractions for developers to use for interprocess communication. Each display monitor hosts five IGCs, one for each data display pane.
