of
character positions (bytes) in storage available
to
the user. Line 1
(input

information entered
from
the keyboard; The cursor (flashing horizontal line) indicates
where the next input from the keyboara

be displayed.
If

a position that already contains a character, that character flashes.
As

processes
the input, all lines
of
the display (except the bottom line)
are
moved up
so

can
be
entered on line 1 again.
