pages of memory and be capable of retaining the position of the cursor on
each page to get the proper effect.
Most state-of-the-art terminals have multiple pages of memory that allow
them to switch between sessions. Each page of memory available on the
terminal allows its user to establish another session on the host. The
multiscreen capability of the terminal stores screen information and cursor
position for each session to a different page of memory.
Multi_View allows the host to process the session-switching hot keys and
issue the necessary escape sequence to the terminal so the appropriate page
displays. Multi_View treats each new screen opened by the user as a virtual
screen and maintains mapping between each virtual screen created and a
page of memory on the terminal. The number of virtual screens and pages
of memory available are dependent on the terminal emulation, the particular
terminal being used, and the number of pseudo devices created by the
system administrator during installation.
In an ideal case, there can be as many virtual screens as there are pages of
memory on the terminal. If more virtual screens are specified than there are
pages of memory, two virtual screens can be mapped to a single page of
memory where both sessionss screens display when that page of memory is
recalled.
Once Multi_View successfully reads the terminal description and initializes
the terminal, the hot key sequence for help displays. The following hot keys
are defined:
Go to n

virtual screen
Create new virtual screen
Switch between current and previous screens
Provide help on hot keys
Quit Multi_View with an exit status of zero
End Multi_View with a nonzero exit status
