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.
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 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:
