Abstract

PURPOSE:To eliminate a need of extension of a picture table area on a main memory by storing picture tables corresponding to display pictures in an auxiliary memory and reading out a prescribed picture table to store it in the main memory in case of display processing. CONSTITUTION:When the picture number of a display picture to be displayed on a CRT display device 3 is inputted from a keyboard 4, a CPU discriminates the picture number to fine that this picture number designates a picture 1. A prescribed picture table is read out from a picture table area 61 of the picture 1 corresponding to the picture number in an auxiliary memory 6 and is stored in a picture table load area 55 in a main memory 5. The CPU1 accesses a processing area 51 of the picture 1 corresponding to the picture number in the memory 5 and executes the processing according with its contents to display the picture 1 designated by the keyboard 4 on the device 3. An area 55 in the memory 5 is accessed also on demand to use picture tables stored in this area 55.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display processing method in a computer system.

[Prior Art] Recently, display means for visually displaying information for man-machine interfaces in computer systems have come into widespread use. FIG. 3 is a block diagram showing an example of such a computer system. In the figure, (1) is a central processing unit (hereinafter referred to as CPU);
(2) is an input/output interface connected to this CPU (1); (3) is a CRT display device as the display means connected to this input/output interface (2); (4)
is a keyboard as an input means connected to the input/output interface (2), (5) is a main memory of the CPU (1), and (6) is an auxiliary memory connected to the CPU (1). .

FIG. 4 is an explanatory diagram showing a conventional display processing method in such a computer system.
5) is shown.

In the figure, (51) and (52) are the screen processing area of screen 1 and the screen processing area of screen 2 set on the main memory (5), and (53) and (54) are also the screen processing area of the main memory (5).
Screen table area of screen l and screen 2 set above
The screen is a table area.

Next, the operation will be explained. FIG. 5 is a flowchart showing the operation of the display processing. CRT display device (3)
When the screen number of the display screen to be displayed is input from the keyboard (4), the CPU (1') first determines the input screen number and determines whether it specifies, for example, screen l. (Step 5TI). Next, the processing area (51) of screen 1 corresponding to the screen number of the main memory (5) is accessed, and processing according to the contents is executed and specified on the CRT display device (3) using the keyboard (4). The displayed screen l is displayed (step 5T2). At this time, the screen table area (53) of screen 1 of the main memory (5) is also accessed as needed, and the screen table stored there is used.

[Problems to be solved by the invention] Since the conventional display processing method is configured as described above, a screen table area for storing a screen table is secured in the main memory (5) corresponding to the display screen. As the number of display screens increases, the main memory (5)
There was a problem in that the upper screen table area increased.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a display processing method that does not require an increase in the screen table area on the main memory even if the number of display screens increases.

[Means for Solving the Problems] The display processing method according to the present invention secures a screen table area in an auxiliary memory to store a screen table corresponding to each display screen, and stores a screen table load area in the main memory. During display processing, the screen table corresponding to the display screen is read from the screen table area of the auxiliary memory corresponding to the input screen number, stored in the screen table load area of the main memory, and then This is used to execute screen-compatible processing.

[Function] In the display processing method according to the present invention, a screen table load area is provided on the main memory, and a screen table corresponding to the J display screen is stored in the screen table area of the auxiliary memory. The screen table read from the screen table area of is stored in the screen table load area of the main memory, and this screen table is used to perform screen corresponding processing according to the contents of the screen processing area associated with the screen number of the main memory. and displays a predetermined display screen on the display means.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. 1st
In the figure, (5) and (6) are the aforementioned main memory and auxiliary memory, and (51) and (52) are this main memory (5).
) are the screen processing area of screen l and the screen processing area of screen 2 set above. In addition, (55) replaces the conventional screen table area (53), (54) with this main memory (
5) The screen table load area set above,
(61) and (62) are the screen table area of screen l and the screen table area of screen 2 set on the auxiliary memory (6), and conventionally, the screen table area (53) or (54) of the main memory (5) ) is stored.

Next, the operation will be explained. FIG. 2 is a flowchart showing the operation of the display processing. CRT display device (3)
When the screen number of the display screen to be displayed is input from the keyboard (4), the CPU (1) will, as in the conventional case,
First, the input screen number is determined, and it is determined that it designates, for example, screen 1 (step 5TI). Next, a predetermined screen table is read from the screen table area (61) of screen 1 corresponding to the screen number of the auxiliary memory (6), and stored in the screen table load area (55) of the main memory (5). (Step 5
T3). The CPLI (1) further accesses the processing area (51) of the screen l corresponding to the screen number in the main memory (5), executes processing according to the content, and displays the keyboard (4) on the CRT display device (3). ) is displayed (step 5T2). At this time, the screen table load area (53) of the main memory (5) is also accessed as necessary to utilize the screen table stored there.

In the above embodiment, a CRT display device is used as the display means, but the present invention may also be applied to a logging device, for example, and the same effects as in the above embodiment can be obtained.

[Effects of the Invention] As described above, according to the present invention, a screen table corresponding to each display screen is stored in the auxiliary memory, and during display processing, a predetermined screen table is read out and stored in the screen table load area of the main memory. As the number of display screens increases, there is no need to reserve an area in the main memory to store all the screen tables corresponding to these display screens, saving main memory usage. I can,
Further, there is an effect that a simple memory map configuration can be obtained.
