CHANGING A SEGMENT'S DISPLAY
Because segments are stored in terminal memory, the terminal can highl ight them ,
make them visible or invisible , and change them in other ways. Because the
terminal is unaware of graphics that are not part of segments (like the circular
panel) , it can't control them once they are displayed.
Segment Visibility
You can remove a segment from the screen without deleting it. By making it
invisible , you can redisplay it by just making it visible .
Make a segment invisible by entering :
SGVISIBILITY 2,NO
Note that the star and brick wall that comprise Segment 2 disappear (Figure 2-4) .
They are still in the terminal's memory, but are currently invisible.
Now, make the segment visible again by entering :
SGVISIBILITY 2,YES
Segment 2 is once again displayed on the terminal's screen .
