Abstract

PURPOSE:To attain automatically the screen address designation at each line at the multistage display, by providing a display control function section containing the mode discrimination of multistage and the screen address control of the mode, for a display controlling device. CONSTITUTION:Various address register sections TZAA for multistage display control are assigned to a part of an RAM in a CRT display control and a keyboard input device CRT/KB controller. Address registers 201AS, 201AE, 201BS and 201BE of the TZAA store each digital address of the left end digit and the right end digit of a paper-tablet shaped areas A, B on the display screen. Address registers 202S, 202E of a register TZBA store the content of the register TZAA of the area in which write is done, and store the next write position to an address register 203 of a register TZCA. The screen address designation of each digit is done automatically with those registers.

Description

Detailed Description of the Invention [Technical Field of CM Akira] The present invention relates to a display control device suitable for use in a Japanese word processor having a multi-column editing function.

[Technical background of the invention and its problems]

In recent years, a ``multi-column # editing function'' has been added to one of the document editing functions of Japanese word processors.

This is a method that divides the two-dimensional space on the CR7 display screen or printing paper into multiple stages, and within the divided area, the character string of the document is displayed or printed in a folded manner like a 1 m 1 diagram. Calibration is also performed within this divided space. At the time of this multi-stage assembly, CRT
The character string of the document is displayed within a narrow digit range from the left digit to the right digit, depending on the configuration of the display screen. Displayed again.

When displaying characters on the CRT 1lii screen using the multi-column display function described above, there is no problem in display control if the display address is instructed to the control device one character at a time. In the case of a control method in which the control device automatically interpolates the address (by specifying the address and then transmitting the character string), the Therefore, when performing multi-column display using address control using the conventional control method, the display rewriting speed decreases and the load on the host device increases. occurs.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and it is possible to estimate the 1iiirTi address tmm of each row of strawberries during multi-stage display.
It is an object of the present invention to provide a display control device which can reduce the negative *O@ applied to a host device and improve the display rewriting speed.

'1 [Praise of the invention] The present invention provides a display control function S that includes a multi-stage mode and screen address 1lllltt for the P water system system, and displays the screen address of the mode when the mode is active. In “
By specifying the leftmost digit position and rightmost digit position of the column ・After the first screen address instruction, the display screen address tube is incremented for the character code string sent sequentially, and the rightmost digit position is The configuration is such that when the rating f is exceeded, the leftmost rating f of the next line is automatically set as the next screen address, so the screen address for each line from the host device can be omitted, and the load on the host device is reduced. It is possible to reduce this and improve the screen rewriting speed.

c Examples of the invention] An embodiment of the present invention will be described below with reference to the drawings.
