Connecting Objects
You connect objects in the Program Flow workspace using connection points on the object. The connection points on an object are usually located over and under the object as shown in the following image.

Objects can be connected using either the upper or lower connectors. However, when you connect an object to an endpoint object, the connector must start from the lower connection point of the source object and end at the upper connection point of the target object.
To connect objects
To connect an object to another object, select the connection point on one of the objects and, without releasing the selection, then move it to start the connection.
Place the connection on the relevant target object and then release the selection.
Once you select the connection point on an object, the connection points on any other object in the workspace where the connection can be dropped are highlighted.
Note: To create a constrained connector, navigate to the Connector object in the palette and change the Constrained attribute to ON by selecting the button before creating the connector. For information about constrained connectors, see Applying Funneling with Constrained Connectors.
