Abstract
Abstract This text processing and display system has the capability of effectively defining and rearranging the format of any selectable section of the block or page of alphanumeric data being displayed. The system involves the combination of a display device for simultaneously displaying a block or page comprising a plurality of lines of alphanumeric characters in ordered display position, with sequentially accessible storage means for storing coded data representations of the displayed characters in a sequence of storage positions spatially corresponding to the positions of the characters in the display block. Repetitive display scanning means are provided for traversing the character display positions in successive lines on the display device together with means for sequentially accessing the data representation for each character to be displayed from the storage means in synchronization with the display scanning means, and means for applying to the display device, signals representative of a whole character to be displayed at a display position prior to the movement of the display scanning means to the next display position whereby each whole character in the display block is refreshed before the next character is refreshed. The spatial limits for a section of stored data corresponding to the selected spatial limit of a section of alphanumeric character in the displayed block are defined by inserting coded data designating the initial character into the storage means immediately preceding the initial character data and inserting the coded data designating the final character immediately succeeding the final character data.

A text processing and display system comprising: a display device for simultaneously displaying a plurality of lines of alphanumeric characters, matrix storage means for storing data representative of the positions of the displayed characters in successive lines of ordered storage locations spatially corresponding to the positions of said characters in said display, means for sequentially storing the coded data representations of said displayed characters in the same sequence as said ordered storage locations of said position representative data for said respective characters in said matrix storage means, repetitive display scanning means for traversing ordered character display positions in successive lines on said display device, means for scanning the ordered storage locations in said matrix storage means in synchronization with said display scanning, means for accessing the data representations for characters being displayed when said matrix scanning means senses a stored character position, and means for applying signals representative of said character data being displayed to said display device in response to said accessed character representation.
Claim 2
Dependent Claim
165 words
A text processing and display system comprising: a display device for simultaneously displaying a plurality of lines of alphanumeric characters, matrix storage means for storing data representative of the positions of the displayed characters in successive lines of ordered storage locations spatially corresponding to the positions of said characters in said display, means for sequentially storing the coded data representations of said displayed characters in the same sequence as said ordered storage locations of said position representative data for said respective characters in said matrix storage means, repetitive display scanning means for traversing ordered character display positions in successive lines on said display device, means for scanning the ordered storage locations in said matrix storage means in synchronization with said display scanning, means for accessing the data representations for characters being displayed when said matrix scanning means senses a stored character position, and means for applying signals representative of said character data being displayed to said display device in response to said accessed character representation.
Claim 3
Dependent Claim
28 words
The text processing and display system of claim 1 wherein said display device is a cathode ray tube display and said display scanning means are raster scanning means.
Claim 4
Dependent Claim
64 words
The text processing and display system of claim 1 wherein coded data representative of an attribute of at least one next successive character is stored in said sequential storage means immediately preceding said character data and accessed when said character data is accessed, and said means for applying signals representing said character, further apply associated signals representative of said attribute to said display device.
Claim 5
Dependent Claim
51 words
The text processing and display system of claim 3 wherein the coded data is representative of an attribute of a plurality of next successive characters, and further including coded data representative of the termination of said attribute immediately succeeding the coded data representative of the last of said plurality of characters.
Claim 6
Dependent Claim
30 words
The text processing and display system of claim 1 wherein said displayed alphanumeric characters are arranged in said ordered locations with variable spacing there between dependent upon varying character widths.
Claim 7
Dependent Claim
44 words

Claim 8
Dependent Claim
48 words
The text processing and display system of claim 5 wherein said matrix storage means is a two-dimensional matrix of binary units arranged in said lines and each of said storage locations has a variable number of said binary units dependent upon the width of the corresponding displayed character.
Claim 9
Dependent Claim
152 words
The text processing and display system of claim 1 further including means for defining spatial limits for a block of stored data corresponding to the spatial limits of a block of alphanumeric characters in said display comprising: means for inserting data designating the position of the initial alphanumeric character in said block into a storage location in said matrix corresponding to the display position of said initial character, means for inserting coded data designating said initial character in said block into said sequential storage means immediately preceding the coded data representation of said character, means for inserting data designating the position of the final alphanumeric character in said block into a storage location in said matrix corresponding to the display position of said final character, and means for inserting coded data designating said final character in said block into said sequential storage means immediately succeeding the coded data representative of said character.
