Drawing one influence diagram per adjustment

Consider the example code in Figure 11.1, where A,B,D,E,F,X,Y,Z are the names of elements or bases to take part in the adjustment. The influence  option is used to switch on the influence diagram display. Next, the overwrite  control is switched off (it is switched on by default). When this command is switched off, the graphics screen is cleared when the new adjustment begins. The sequence of commands shown in Figure 11.1 will achieve the following:

1. display an influence diagram for the adjustment ;
2. clear the graphics screen;
3. display an influence diagram for the adjustment .
4. the diagram will remain in the graphics window - you can return to the text window and resume processing.
