Abstract
Abstract A display system for horizontally segmenting text made up of varying width characters and spaces. When a text measure is wider than the width of a display device, only a portion of the text can be displayed at one time. By dividing the text into segments, all of the text can be ultimately displayed. This is done automatically dependent upon the current location of a cursor positioned within one of the lines of the text. Entire lines of text, including a scale line, are sequentially loaded into a line buffer beginning with the line containing the cursor. A segment of the line containing the cursor is determined and displayed, and then corresponding segments of subsequent lines are determined and displayed. Thereafter, a corresponding segment of the scale line is determined and displayed. The display includes only whole characters adjacent its left edge.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
164 words
In a system for displaying information such as a number of lines of characters, symbols, etc., in horizontal segments, due to a measure, which is the distance between a left and a right margin, for said information being wider than the width of a display included in said system, the improvement comprising in combination: (a) means for selecting an operating mode for said system including a proportional spacing mode; (b) means when operating in said proportional spacing mode for horizontally segmenting said information to obtain, for display, a horizontal segment of said information having a beginning following and not including a beginning of said measure and made up of a segment of each of said lines with each horizontal segment beginning with each whole character, symbol, etc., following (1) said beginning of said horizontal segement and (2) any character, symbol, etc., which overlaps said beginning of said horizontal segment to be displayed; and (c) means for separately displaying said horizontal segment of said information.
Claim 2
Dependent Claim
164 words
In a system for displaying information such as a number of lines of characters, symbols, etc., in horizontal segments, due to a measure, which is the distance between a left and a right margin, for said information being wider than the width of a display included in said system, the improvement comprising in combination: (a) means for selecting an operating mode for said system including a proportional spacing mode; (b) means when operating in said proportional spacing mode for horizontally segmenting said information to obtain, for display, a horizontal segment of said information having a beginning following and not including a beginning of said measure and made up of a segment of each of said lines with each horizontal segment beginning with each whole character, symbol, etc., following (1) said beginning of said horizontal segement and (2) any character, symbol, etc., which overlaps said beginning of said horizontal segment to be displayed; and (c) means for separately displaying said horizontal segment of said information.
Claim 3
Dependent Claim
33 words
A system according to claim 1 including means for defining an operating point in one of said lines of said horizontal segment which is obtained by said means for horizontally segmenting said information.
Claim 4
Dependent Claim
160 words
A system according to claim 2: (a) including a first storage means for storing said information to be segmented by said means for horizontally segmenting said information; a second storage means for storing one of said lines of said information to be segmented by said means for horizontally segmenting said information; and means for sequentially transferring said lines of said information beginning with said line having said operating point defined therein from said first storage means to said second storage means; (b) wherein said means for horizontally segmenting said information includes means for determining a segment; (c) including a third storage means for storing said segment determined by said means for determining a segment; (d) wherein said means for horizontally segmenting said information includes means for transferring said segment to said third storage means; and (e) including a fourth storage means for storing a scale line for said information to be segmented by said means for horizontally segmenting said information.
Claim 5
Dependent Claim
36 words
A system according to claim 3 wherein said means for sequentially transferring said lines to said second storage means includes means for transferring said scale line from said fourth storage means to said second storage means.
Claim 6
Dependent Claim
34 words
A system according to claim 4 wherein said means for determining a segment includes means for determinig corresponding segments of lines, including said scale line, following said line having said operating point defined therein.
Claim 7
Dependent Claim
30 words
A system according to claim 5 wherein said means for transferring said segment to said third storage means includes means for transferring said corresponding segments to said third storage means.
Claim 8
Dependent Claim
20 words
A system according to claim 6 wherein said display means includes means for displaying said segment and said corresponding segments.
Claim 9
Dependent Claim
20 words
A system according to claim 7 including means for causing said scale line segment to be displayed in standard spacing.
Claim 10
Dependent Claim
19 words
A system according to claim 8 wherein said mode selection means includes means for selecting a standard spacing mode.
Claim 11
Dependent Claim
31 words
A system according to claim 2 wherein said display means includes means for displaying said horizontal segment of said information containing said operating point adjacent a left edge of said display.
Claim 12
Independent Claim
132 words
A system for horizontally scrolling information, such as a number of lines of characters, symbols, etc., by segments for display, said lines extending between a left and a right margin, said system comprising: (a) means for selecting an operating mode for said system including a proportional spacing mode; (b) means for defining a plurality of horizontal segments of said information between said left and right margins; (c) means, when operating in said proportional spacing mode, for obtaining said segments of said information made up of a segment of each of said lines with each segment beginning with each whole character, symbol, etc., following any character, symbol, etc., which overlaps a beginning of said segments; and (d) means for separately displaying each of said segments of said information for horizontally scrolling said information.
Claim 13
Independent Claim
132 words
A system for horizontally scrolling information, such as a number of lines of characters, symbols, etc., by segments for display, said lines extending between a left and a right margin, said system comprising: (a) means for selecting an operating mode for said system including a proportional spacing mode; (b) means for defining a plurality of horizontal segments of said information between said left and right margins; (c) means, when operating in said proportional spacing mode, for obtaining said segments of said information made up of a segment of each of said lines with each segment beginning with each whole character, symbol, etc., following any character, symbol, etc., which overlaps a beginning of said segments; and (d) means for separately displaying each of said segments of said information for horizontally scrolling said information.
