Scroll Blocks for Positioning On Non-Programmable Terminals

       This article describes a method in an application program
for navigating within a large document displayed on a
non-programmable terminal (NPT).

      If a user is viewing a large document on an NPT and the entire
document does not fit on the screen at once, the user needs some
visual cues to show how to get to the rest of the document.  IBM's
Common User Access (CUA) (SAA Common User Access Basic Interface
Design Guide SC26-4583) defines scrolling information that is meant
to point the user in the correct direction.  According to CUA, the
application displays scrolling information as
 More: < + - > showing information is to the left, above, below and
right (respectively) of the visible area.  This scrolling information
shows the user in which direction to go to see more of the document,
but does not provide any information about where the user is within
the document.

      The method expands the scrolling information to include
location within the document and also provides a technique to rapidly
move through the document.
-    When an object that will overflow the screen is to be displayed
on an NPT terminal, an icon shaped like a tic-tac-toe board is shown
in the upper right corner. This is called a scroll box.
-    The application program divides the object into ninths and shows
the first portion of the object.  The amount of the object being
shown on the screen is indicated by...
