PT Program Generator (PPG) v5.0
Flow Chart Levels
After creating an empty application with the File New command, start in the
main frame level. Nodes at this level should include frames and subroutines
defining major steps in the application. Take advantage of the parent-child
relationship to organize the application in a logical and maintainable fashion.
To access the steps within a frame or subroutine, double-click on the frame
with the left mouse
button or select View > Show Frame/Subroutine Nodes
from the menubar. To return to the higher level, double-click on one of the
Exit or Entry nodes or choose View > Show Calling Function from the
menubar.
Frames
Each frame in a program flow chart represents a major function or option.
Typically, a program's frames include a
Main Menu frame and a frame for each
option on the menu. Links connect the frames in a way that indicates program
flow.
Figure 29 shows the start frame of the sample2.scr application
installed with PPG.
