Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a method for controlling and controlling graph ink screens, especially multi-job operation for display screens that display text screens and graph ink screens in a superimposed manner. This relates to the job frame control force f (of the graphic screen that occasionally maintains screen switching).

[Conventional technology and problems]

Conventionally, graphics processing on terminals has been an optional feature, and when switching the projection screen of the terminal display to another job frame during graph ink processing in multi-jijibu operation 1. The graph ink screen was not controlled during the process.

Therefore, for example, as shown in Figure 5, the display (
When the character screen and the graph ink screen are superimposed on the screen 1 and the screen switching key 3 is pressed from the keyboard 2, the character screen is switched to another job frame and the graphic image 1f11ζ, 1 is not erased. ζ The original screen will be left in a pile. If you try to erase 1h1 of graphics or pictures,
Double-sided switching requires key operations other than 3, for example: 1 control key and other key combinations, υ key operations, which makes the operation cumbersome, and also makes it difficult to switch between the text screen, graphics, and screen. There was a problem with not being able to synchronize.

[Failure to solve the problem]

The present invention aims to solve the problems mentioned in item 1-1 above, and for a display screen that displays a text screen and a graphic screen in a superimposed manner, it is possible to switch between the text screen and the graphic screen at the same time during multi-job operation. The main objective is to provide a job framework and a control method to control the process. Therefore, the graphic screen shove lane control method of the present invention is such that the control method is such that the control method of pressing the key 1/display on one of a plurality of jobs running simultaneously is 1.

The keyboard 1/display control unit 4
It controls the display of the character screen and also controls the key input from the keypad 12.

The second console control unit 5 is a system task that controls both sides of a job frame, which will be described later. Control is performed to attach the virtual keyboard/display to the actually existing display 1, 1, and 1--port 12. Hereinafter, in this embodiment, it is assumed that a maximum of two jobs can be run simultaneously.

The frame switching unit 6 is activated by pressing the double-sided switching key 3 provided on the keyboard F2J:4, and controls switching of frames J related to the display screen of each job. The frame J that is in a state of connection with the actual display is called a foreground frame, and the frame that is not in a state of connection is called a domain frame.

Frame J, information record 1a section 7 contains these frame information,
For example, it is a control table that stores correspondence information between job numbers and frames, correspondence information between frames and main origin (QAlus?υ, etc.).

The job management unit 8 manages the execution and termination of the jobs running on the computer system B. The application processing unit 9 performs a job-based processing.

This is a well-known circuit that displays on the display 1 by superimposing +c, 7+ graph ink patterns.

Next, the relationship between the character screen and the graphic screen will be explained in more detail with reference to FIG.

In general, the operation of the system is carried out through frequent conversations between the operator and the Sosuu-J. Cystine and operation 1
7-Ta conversations are conducted through the -Topo F/Y display. When multiple jobs are running at the same time,
For example, an IQ concept called a frame is introduced to share one keyboard/display between jobs. this)
I/-J may be considered to be screen information related to the above-mentioned 1LI- area in which the job moves. That is, in the above 1011, the first frame L--frame character: 1-1 area 1
Two areas, 2 and 2J-1 for the second frame, are provided corresponding to each frame. Control of the virtual keyboard/display is then performed to effectively combine the two frames 1 with one keyhole 1/display.

The virtual keyboard/display is frame 1, case lj
To a job running on the resulting system or frame, it appears as if there is an actual keyboard/display combination. The real keyboard/display is combined with the virtual keyboard/display of 1-). If the operator wants to switch the virtual keyboard/display coupled to the real keyboard/display to the virtual keyboard/display of the other frame, this can be done at any time by pressing the screen switching key 3 shown in FIG. There is.

There are roughly two types of screens in the system.

One is a character screen, and the other is a CT graph ink screen. The character screen has a virtual screen in the main memory 11 as a character code 1'' (JEF or EBCDIC, etc.) as shown in FIG. 2. One of the virtual screens is associated with an actual physical screen.

Similarly, as shown in FIG. 2, for the graphic screen, a virtual screen is provided in the form of a bitmap in the center of the I10 weighing scale. By switching the screen, it is possible to make that one virtual screen correspond to the physical screen.

The projected screen on the display that is actually visible to the operator is a superimposed display of the physical screen of the above characters and the physical screen of the -1- graphic.

Therefore, in order to control frames, it is necessary to switch between two screens: a character screen and a graphic screen. This switching I trigger is provided by the screen switching port 3 provided on the port 2 as described above.

Here, in the conventional method, since the control of the graphic screen is handled as an ozone-like function and is treated as a -C phase, only the switching of both sides of the characters is performed, but according to the present invention, the following Δ Switching control is performed.

For example, in FIG. 3, first, the first arene,
Assume that a corresponding character screen and a graphic screen are displayed on the display 1. Here, when the operator presses the screen switching key 3, the following control section is performed.

(2) The console control unit 5 is notified that the screen switching key 3 has been pressed.

(2) The frame switching section 6 is activated by the console control section 5, and the frame switching section 6 performs frame switching of the character screen.

(2) This causes the character screen to be switched from the first frame to the second frame (/-J).

(2) Next, the frame switching section 6 notifies the graph ink screen control section IO of frame switching 71/-.

■ With this notification, the graphic screen control unit IO will
Changes the frame of the graph ink screen.

■ This causes the graph ink screen to change to the first frame 1.
will be switched from to the second frame,
Both the character screen and the graph ink screen will be switched.

FIG. 4 shows the processing of the frame switching unit 6 and the graphic screen control unit 10 at this time) [1-]. The frame switching section 6 is activated using, for example, the switching destination tree 1 and number as parameters. First ζ2 determines whether the specified frame number is correct. If the specified frame number is equal to the current I-nome number, the process ends with an error. If the frame number of the finger is correct, perform the following processing. In addition, when switching frame J, ′ci
t, actually -1- of the advance input regarding baud 1゛;1-
Jansel processing "~ is also performed, but the explanation will be limited to screen control and will be explained in 14.

First, what about the physical screen explained in Figure 2? do.

Then, for example, the display area information and the old frame information of "1 flag" are stored in the frame 1 shown in FIG.
evacuate to. Next, the current frame number is switched to the specified new frame number, and the character screen is switched. It may be assumed that the above process is performed in the same manner as before.

Next, a request is made to the graphic screen control unit 10 to change the graphic screen using the 1 and -l interface. When the graphic screen control unit 102 receives the macro L2, it determines whether it is a request for screen switching based on whether the macro issuing source is the frame 1 or the switching unit 6. When the activation is not from the frame switching unit 6, normal macro processing is performed. In the case of activation by frame 1 and switching unit 6, it is determined whether or not it is necessary to change the display of the graph ink screen by checking the job number and the currently displayed screen state information. If a display change is necessary, the graph ink screen is changed, macro 0 return information is set in a predetermined register, and control is returned to the macro issuer.

The frame switching unit 6 then sets new frame information in the frame information storage unit 7 shown in FIG. 1, and ends the process.

〔Effect of the invention〕

As explained above-1-, according to the present invention, during multi-job operation, in response to a screen switching instruction, the text screen and graph ink screen are switched in synchronization, and both the text screen and the graphic screen are placed in a frame. Because it is integrated and controlled, there is confusion on the projection screen of the De3 Display! I never do anything.

Moreover, switching is possible easily without requiring any special operation.
