Creating New Nodes

2.To position the subroutine, move the pointer to it, hold down the left mouse button, and drag the subroutine with the mouse. When the subroutine is positioned where you want it, release the mouse button. Since subroutines aren’t Linked to other objects, their locations are optional. Normally, they are placed to one side of the frame.

3.To give the subroutine a more useful name, select Edit > Properties from the menubar or select Properties from the pop-up menu (point and click the right mouse button). This opens the Subroutine Proper- ties dialog box (Figure 30 on page 51). Enter the new name in the name field, and select OK.

If you're creating several subroutines, you can create a single subroutines as described above. Then select the subroutine by clicking on it with the left mouse but- ton. Copy the subroutine by selecting Edit > Copy from the menu. Then select Edit > Paste as many times as necessary to create the number of copies you need.

To reference a subroutine from within a frame, use a Call node (refer to Call Nodes on page 72). When the subroutine has been executed, control continues with the next node after the Call node.

Creating New Nodes

Each Frame and Subroutine of a program flow chart contains its own set of nodes, in a child (sub-level) flow chart. Every Frame is assigned at least one node automatically: a Start node, which shows the name of the Frame. If the Frame contains Links to other frames, an Exit node for each Link is also created automatically. A subroutine has a Start node and a Return node, which are created automatically by PPG. You add and Link your own nodes to define details for the Frame.

To get to the Operation level of a frame, double-click on it. You can also move to it with the mouse and then select

from the menubar.

To create a node, complete the following steps:

1.Select the type of node you want to create from the Create menu. A new node will appear in the lower right corner of the frame window. The new node is assigned a default name.
