- ** PROGRAM SETUP **
-
- The program consists of the following independent parts:
- Input system data
- Time response
- Root loci
- Frequency analysis
- Close control loop
- System Matrix
- Display of system - page-overview
- Options
- Transition from the one independent part to the other independent
- part always occurs via the main menu (F10).
- The system data are entered through the keyboard or from a data
- file. The various program parts use these data and, in general, do
- not change them. Data are exchanged when new data are entered or
- when data are changed via F6. Old data are automatically saved on a
- scratch pad. Five scratch pages are available. When the scratch pad
- is full, the oldest data are discarded. All the data on the scratch
- pad may be called back and/or reactivated in the menu item
- 'Display of system - page overview'.
