### Return Value

Boolean

### Examples

#### JScript Example

    /*
             This example illustrates how to use the AddPortGroup method to define
             an PortGroup. Use this method if you want to determine the number
             of objects that can be connected to the group or restrict the
             types of objects connecting to the group by using a filter.
