          GRAPHICS IMPLEMENTATION AND CONCEPTUALIZATION AT ARC

Overview:

This document is a brief description of the way in which graphics
terminals are conceptualized and used at the Augmentation
Research Center. All things described are implemented and have
been operational for several months. Although our attention has
initially been centered about the display of textual material, we
are now about to turn our attention toward pictorial displays
(hopefully much enhanced over our previous 940 line drawing
capabilities).

   This document will discuss only those facits of display use
   which have been implemented and are currently operational,
   namely only those dealing with textual display.

included is a discussion of the use of multiple file viewing
display areas in NLS to provide cross file editing capabilities.
A description of our display and terminal input equipment will
be issued as a separate document.

NOTE: RFC 190 includes a functional description of the
implementation of the interface to our displays and is a
description of the way this interface was extended to include
"Processor-displays" (an IMLAC PDS-1, in this case) to our
system, thus enabling one to use Display NLS over any of our
teletype lines (including the network).

   A "processor dsplay" is a display with Processing power which
   can be controlled by character strings.

Description of the "conceptual display" implemented at ARC

The allocatable output unit for our display terminals (which
include our local terminals and all remote processor-displays) is
