Description

Description: TECHNICAL FIELD The present invention relates to a multi-window display device of a data processing system to which a plurality of terminals are connected.
The contents of the window displayed on the terminal side can be displayed on the screen in one of the windows of the main console, so that the administrator of the main console can grasp the work contents in each terminal and the progress thereof, and The present invention relates to a multi-window display device capable of improving the management efficiency of a data processing system by enabling an appropriate response to various troubles occurring on a terminal side.

2. Description of the Related Art In recent years, with the rapid spread of office automation, data processing systems connecting a plurality of terminals have been introduced in many offices.

In such a data processing system, the main console (host side) having a central processing unit (CPU) and the terminal side are installed on different floors in the same building, or are installed separately in different buildings. In many cases, it is done.

In such a case, usually, the administrator of the main console is familiar with the expertise of the data processing apparatus, but the operator on the terminal side does not always have deep knowledge.

However, in a conventional data processing system to which a plurality of terminals can be connected, the status of each terminal cannot be accurately grasped on the main console.

In other words, on the main console, whether or not each terminal is in operation, a job corresponding to the terminal is displayed.
I couldn't tell at all whether I was waiting for I / O or active, but what exactly was displayed on the terminal screen.

For this reason, it is not possible to accurately grasp the progress status of the job for each terminal, and it may be possible to turn off the CPU.

If you accidentally turn off the CPU, the data being processed at the terminal will be lost. For example, if a program is being created on an editor, or a document is being created on a word processor, but before writing to a file, it will take a considerable amount of time and effort to recover, and work and efficiency will be reduced. It is also a problem from above.

The multi-window display device of the present invention aims to solve such a problem. However, in order to facilitate understanding, first, an outline of a data processing system having a conventional multi-window display system will be described. Will be described.

The display data passed to these virtual devices B1 to Bm of the main console, or the virtual devices Bn1 to Bnm of the n-th terminal are stored in the corresponding virtual screen memories C1 to Cm or virtual screen memory Cn1 provided next. ~ Cnm.

Generally, in a multi-window display system, these virtual screen memories C1 to Cm and Cn1 to Cnm correspond to each window.

On the main console (host side), each virtual screen memory is controlled by the multi-window input / output control unit D.
Part of the data of C1 to Cm is cut out, synthesized on the next real screen memory E, and finally displayed on the screen of the display device F composed of a CRT or the like.

Similarly, in the nth terminal, the data of each virtual screen memory Cn1 to Cnm is partially cut out by the multi-window input / output control unit Dn and synthesized on the next real screen memory En.
Finally, it is displayed on the screen of the display device Fn composed of a CRT or the like.

 Next, the input data will be described.

In the main console, the input device G is connected to the multi-window input / output control unit D.
It is controlled by the input device G. That is, the data from the input control G is transmitted to the multi-window input / output control unit D.
To the corresponding virtual devices B1 to Bm.

Finally, the data is passed to the user programs of the process units A1 to Am.

Similarly, on the n-th terminal side, data from the input device Gn is passed to the corresponding virtual devices Bn1 to Bnm via the multi-window input / output control unit Dn.

By such an operation, multi-window display is performed.
