SECTION
Because the screen is a window, the line of data which scrolls off the screen need not be
scrolling out of memory. And the line of data which scrolls out of memory need not be the
one scrolling off screen (see Figure 3-4). The distinction here is important: what scrolls off
the screen but remains in memory can be redisplayed; what scrolls out of memory is "lost",
it cannot be redisplayed.
