Automatically Generated Nodes

Start Nodes

Start nodes point to the first node in each frame. The are created automatically by PPG when a frame or a subroutine is created.

Exit Nodes

Exit nodes indicate where the frame ends and returns to its parent frame. Exit nodes are created automatically by PPG when you create a Link from one frame to another. (Refer to Node Types and the Parent-Child Relationship on page 17 for more information on the parent-child relationship between nodes.)

Return Nodes

Return nodes indicate where a subroutine ends and returns to its calling node. Return nodes are created automatically by PPG when subroutines are created.
