Now we can create the Environment and the training patterns. Locate the Project window, and select .environments / New / Environment and Ok. Your EnviroView window will appear. Then click New Event. Set the number to create to 4, then click Ok. You should see Panel buttons for all four events ("Event_0".."Event_3"). Left-click the first one to select it for viewing, then extend-select (middle-click or Shift + left-click) the rest in order, and all of them will appear to the right of the buttons. They automatically have an input pattern the same size as the input layer and an output or target pattern the same size as the output layer, and all the values of all of the patterns are initialized to 0. Both input and output patterns are displayed with the top four boxes of each event represent the output target values and the lower four boxes representing the input values. You can now set the 1 bits of each pattern by clicking on the color spot next to the value field labeled '1', then clicking on the appropriate elements of the pattern. They will turn to the appropriate color, indicating the specified value. You have to click Apply for the change to take effect. Now you have your environment. Iconify it.
