If the Procedure is not used as a Function (i.e. it does not return any value to a Calling Procedure), then the Exit component is used instead of the Return component.
Whereas a Procedure can have only a single entry point (either a Parameter component or an Entry component), it can have many terminators. If one Exit component is not sufficient, just drag another one from the Palette.
Flow direction lines (arrows) cannot originate in the Exit component; it can only terminate the lines. However more than one flow direction line can terminate in a single Exit component.
