Abstract

An information processing apparatus for processing document information including image information has a printer, a line number register, registers for storing format information for each line displayed on a screen of a CRT display, and a processing section for retrieving the format information corresponding to a portion of document information at which the cursor is currently located and for allowing the display to display the document information together with the format information.

Claims

1. An information processing apparatus comprising:

input means for inputting character information;

memory means for storing the character information input by said input means;

display means for displaying the character information stored in said memory means on a plurality of lines and tab format and a cursor;

format memory means for storing respective tab format information defined for each of the plurality of lines;

position designating means for designating, with the cursor, a display position, on said display means, in which the character information is displayed;

means for, when said position designating means moves the cursor from one of the plurality of lines to another, reading the tab format information for the another line, which tab format information is different from that defined for the one line, from said format memory means; and

means for controlling said display means to display respective tab format information for the line on which the cursor is positioned by said position designation means in response to the updated read tab format information read by said reading means and for controlling said display means to change the tab format information displayed by said display means based on the updated read tab format information read by said reading means when the cursor is moved to a different line by said position designation means.

2. An apparatus according to claim 1, wherein said format memory means stores the tab format information defined for each of the lines simultaneously.

3. An apparatus according to claim 1, further comprising cursor position memory means for storing position information of the cursor and switching means for switching the tab format information read from said format memory means in response to the position information stored in said cursor position memory means.

4. An apparatus according to claim 1, wherein said display means can display a plurality of lines of the character information simultaneously.

5. An information processing apparatus comprising:

input means for inputting character information;

memory means for storing the character information input by said input means;

display means for displaying the character information stored in said memory means on a plurality of lines and format and a cursor;

format memory means for storing a plurality of types of format information defined for each of the plurality of lines;

position designating means for designating, with the cursor, a display position, on said display means, in which the character information is displayed;

means for, when said position designating means moves the cursor from one of the plurality of lines to another, reading the format information for the another line, which format information is different from that defined for the one line, from said format memory means; and

means for controlling said display means to display respective format information for the line on which the cursor is positioned by said position designation means in response to the updated read format information read by said reading means and for controlling said display means to change the format information displayed by said display means based on the updated read format information read by said reading means when the cursor is moved to a different line by said position designation means.

6. An apparatus according to claim 5, wherein said format memory means stores the format information defined for each of the lines simultaneously.

7. An apparatus according to claim 5, wherein said display means can display a plurality of lines of the character information simultaneously.

8. An apparatus according to claim 5, wherein said format memory means comprises an area for storing tab information and an area for storing margin information.

9. An information processing method comprising the steps of:

displaying on display means character information stored in a memory on a plurality of lines and format information stored in a format memory;

designating with a cursor, a display position on the display means in which the character information is displayed, and moving the cursor from one of the plurality of lines to another;

reading format information for the another line from the format memory means, which format information is different from the format information defined for the one line; and

controlling said displaying step to display respective format information for the line on which the cursor is positioned by said position designating step in response to the updated read format information read by said reading step and for controlling said displaying step to change the format information displayed by the display means based on the updated read format information read by said reading step when the cursor is moved to a different line by said position designating step.

10. A method according to claim 9, wherein said reading step comprises switching the format information read from the format memory in response to said moving step moving the cursor.

11. An information processing apparatus comprising:

input means for inputting information;

memory means for storing the information input by said input means;

display means for displaying the information stored in said memory means on a plurality of lines and format information;

position designating means for designating a display position, on said display means, in which the information is displayed;

means for, when said position designating means moves the designated display position from one of the plurality of lines to another, updating the format information displayed by said display means, which format is different from the format of the another line, to correspond the format of the one line to the format of the another line; and

means for controlling said display means to display respective format information for the line of the designated display position designated by said position designation means in response to the updated format information and for controlling said display means to change the format information displayed by said display means based on the updated format information when the designated display position is moved to a different line by said position designation means.

12. An apparatus according to claim 11, further comprising means for displaying the format updated by said updating means.

13. An apparatus according to claim 11, wherein said display means can display a plurality of lines of the information simultaneously.

14. A storage medium of an information processing apparatus storing program means for causing the information processing apparatus to control display means to automatically change displayed format information for a line of text when a cursor is moved from one of a plurality of lines to another in the event the one line and the another line have different formats, said program means in said storage medium of the information processing apparatus comprising:

means for causing the display means to display character information stored in a memory on a plurality of lines and format information stored in a format memory;

means for causing a cursor displayed on the display means to move from one of the plurality of lines to another;

means for causing the reading of format information for the another line from the format memory which format information is different from the format information defined for the one line; and

means for causing the display means to display format information for the one line when the cursor is positioned on the one line and to display format information for the another line when the cursor is moved to the another line in response to the read format information and for causing the display means to change the displayed format information based on the read format information when the cursor is moved from the one line to the another line.
