Abstract

When output is being scrolled to a display screen, it is usually desirable to pause when the screen has been filled to allow the screen to be read before continuing. Conventionally, provision has been made to allow the screen to be cleared after having been read by the user so that the next screen of output may be displayed. There are times when the user may not want to clear the entire screen. The display of a logical block of data may start in the middle of the screen and be continued on the next logical screen. The user may want to move the start of the logical block to the top of the screen so that s/he can view the entire logical block together as a unit. Thus, what is needed is a simple way to allow a user to clear a partial screen.

Partial Clearing of Scrolling Display Screen

      When output is being scrolled to a display screen, it is
usually desirable to pause when the screen has been filled to allow
the screen to be read before continuing. Conventionally, provision
has been made to allow the screen to be cleared after having been
read by the user so that the next screen of output may be displayed.
There are times when the user may not want to clear the entire
screen.  The display of a  logical block of data may start in the
middle of the screen and be continued on the next logical screen. The
user may want to move the start of the logical block to the top of
the screen so that s/he can view the entire logical block together as
a unit.  Thus, what is needed is a simple way to allow a user to
clear a partial screen.

      This invention accomplishes this function.  The user, using the
cursor movement keys on the terminal, places the cursor on the line
which s/he wishes to appear at the top of the screen.  The enter key
is then pressed and this causes all lines above the one identified by
the cursor to be cleared and the line identified by the cursor to
become the top line on the screen.  With this procedure, the user can
easily clear any portion of the screen so that s/he may view logical
blocks of data together on a single screen.
