| - | The single selection rule tests an input and calculates the defined output based on a simple logical relation. The Input "object" can be of any type available, but the output one can only be a position or a variable. If the input is set to be a variable, its value may come directly from a field placed in a mask or a default value. The output quantity ("Q out") is determined by the input quantity ("Q in"). If they are both set to "1", then for every number of input there will be an output. On the other hand, if the "Q out" fields is set to 2, it means that for every input there will be 2 output. | + | The single selection rule tests an input and calculates the defined output based on a simple logical relation.
