11 Using Operator Interfaces Chapter

This creates an input object that uses a Check Box. If the

operator clicks the box, an X will appear and the object

outputs a 1; otherwise, the object outputs a 0. The output

can be tested with an If/Then/Else object to tell VEE what

to do next.

18 Select Flow ⇒ If/Then/Else and place it to the right of the

Toggle. Connect the Toggle data output to the data input A

of the If/Then/Else object. Edit the expression in the

If/Then/Else object to: a == 1. (Recall that the symbol for

“is equal to” is ==, not =.) If the terminal A holds a 1, the

Then output will fire; otherwise, the Else output fires.

Connect the output of Toggle to the input of If/Then/Else.

19 Select Flow ⇒ Repeat ⇒ Break and connect it to the Then

output on the If/Then/Else object, as shown in

Figure 243.

the right side of the object. Open the pop- up Edit menu

the Check Box.
