VIRTUAL SCREEN
The eight by forty characters on the LCD are only one sixth of
the nur:iber of characters contained within the virtual screen,
The LCD acts as a window onto the virtual screen, The contents
of the virtual screen may be inspected at will by using the
cursor control keys in their shifted state,
SCREEN SIZE
HUNTER's virtual screen is 80 characters by 24 lines. The
virtual screen behaves very much like a terminal with automatic
scrolling. When the cursor reaches the bottom line, the rest
scrolls up losing the top line,
MOVING THE WINDOW
The window r:iay be moved over the virtual screen either manually
by the user, or automatically by the virtual screen handler
resident in the operating syster:i and as such is transparent to
the user.
Manual Movement
1) Shifted state cursor control keys (looking keys):
By using the cursor control keys in their shifted state, the
window can be made to move in the direction marked on the key,
i.e. press the 'shift' key, hold it down, and then press the
desired cursor control key, When this operation is performed it
will be noticed that the cursor on the LCD (a blank flashing
block) will change its position on the LCD and quite often
disappear. This will happen because the cursor position refers
to the position in the virtual screen, and when the window is
moved the cursor position relative to the window position in the
virtual screen will change,
2) Function "cursor control keys"
By pressing CTL/Frl and either horizontal arroH key, then either
the 12ft or right 40 characters of the screen can be seen, This
function is useful for easy readimi of 1,ide screen for.;1ats.
