Abstract

PURPOSE:To shorten the waiting time for answer by attaining the input of the next data to a display device even though the answer to the data transferred to a central processor from a display device is not sent back to the display device. CONSTITUTION:The data on a buffer 7 and the data on an auxiliary buffer 8 are stored immediately to a screen synthesizing buffer 9 for synthesization and sent to a host 1 together with display as long as the answer of the host 1 is already received when an ENTER key is pushed after the desired data are supplied through a keyboard of a display device 3 if a host answer is exist. In a waiting mode for host answer, an answer waiting flag is turned on to set an answer waiting mode. Then the data on both buffers 7 and 8 stored to the buffer 9 together with the answer signal given from the host 1 for synthesization and then sent to the host 1 together with display.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data input method that allows the next input data to be input and displayed before a response to data transferred to a central processing unit is returned.

Some information processing apparatuses are connected to a display apparatus using a time-sharing method, and data is exchanged between the display apparatuses in a conversational manner.

In such a system, it is strongly desired that the conversation be carried out as smoothly as possible from the viewpoint of improving its processing performance.

[Conventional technology]

A conventional display device connected to an information processing device in a time-sharing manner is configured such that input from the display device can only be started upon receiving a response from the information processing device.

[Problem that the invention seeks to solve]

Therefore, if the response is returned within a relatively short period of time, no major problem will occur.

However, even if the system is operating in such a way that the response waiting time becomes long and there is a lot of data that people want to input, it is not possible to input the data that they want to input using the data input method described above, and the response waiting time mentioned above becomes long. remains to be wasted.

[Means for solving problems]

- The present invention provides a data input method capable of solving the above-mentioned problems, and the means thereof includes an auxiliary buffer and a data transfer means of the display device in a display device connected to a central processing unit that performs various processing. human means for inputting second data into the auxiliary buffer before a response to the first data transferred by is returned to the display device; display control means for displaying the data on a screen of the display device; means for combining and storing response data to said first data from a central processing unit and said second data and causing said display control means to display said data on said screen; and means for transmitting the composite screen data to said data transfer means. and means for transmitting the data to the central processing unit.

[Effect]

According to the method of the present invention, even if a response to data transferred from the display device to the central processing unit is not returned to the display device, the next input data can be input to the display device, thereby eliminating the problems caused by waiting for a conventional response. Can be removed.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows an embodiment of the invention. In this figure, 1
is a host (central processing unit), to which a terminal device such as a display device 3 is connected via a terminal controller 2 in a time sharing manner.

The display device 3 presses the RESET key, ENTER
A keyboard 4 having function keys such as keys and general data keys, a main processing section 5 that generates a required operation in response to pressing of each key on the keyboard 4, and a main processing section 5.
A buffer 7 is used to store and display data under the control of the main processor 5, and transfer the data to the host l via the interface unit 6 and the terminal controller 2 as necessary. An auxiliary buffer 8 is used to store and display input data before a response to the data transferred to the host 1 is returned, and a buffer 7 and The screen composition buffer 9 is used to combine and store and display the data of 8 and transfer the combined data to the host 1. And the main processing section 5
An ENTER wait flag and a response wait flag can be set.

With this configuration, the next input data can be input even if no response is returned from the host 1.

That is, the initial transfer of input data from the display device to the host is performed through normal processing. This will be explained using the processing flow shown in FIG. 2 as follows. This is a check when inputting data. If the key pressed is the RESET key (or if it is a general data key and is not in the E N T E'R wait state, each data input with that general data key will be processed in normal processing. In this way, when the required input data (initial input data) is inputted and the ENTER key is pressed down, the pressed key becomes the RESET key, not the general data key, but the ENTER key. In this case, as will be explained later, there is no need to wait for ENTER, so normal processing begins, and in response to the pressing of the ENTER key, the data in the buffer 7 is sent to the ink face section 6 and the terminal controller 2. The data is then transferred to the host 1 (see Figure 4).

The inputting of data on the display device side in the dormant state in which it waits for a response from the host 1 will be described next.

Press the RESET key before pressing the general data key. As a result, there is a large blade tipping function as 0PTION, and it is waiting for a host response, so press ENTER.
The wait flag is turned on and the auxiliary buffer 8 is used as the input buffer to wait for input. After making these device settings, press down on the General Data key.
When entering data, the key to press is R.
It's not an ESET key, it's a general data key, and it's an ENTE key.
Since it is waiting for R, each of the data input from the general data key is sequentially stored and displayed in the auxiliary buffer 8 (
(See Figure 4).

After entering the necessary data in this way,
If you press down the NTER key, check '7' when inputting data.
The key to press when entering is the ENTER key, not the RESET key or the general data key.
Waiting for R.

If there is already a host response at this time, the data in the buffer 7 and the data in the auxiliary buffer 8 are immediately combined and stored in the screen composition buffer 9 and transmitted to the host 1 while being displayed.

In addition, if it is waiting for a response from the host, it turns on the response waiting flag and enters the waiting for a response, and when the response from the host 1 is received, the data in the buffer 7 and the data in the auxiliary buffer 8 are combined and stored in the screen composition buffer 9. It is also displayed and transmitted to the host 1 (see FIGS. 4 and 5). As shown in Figure 5 (cross-hatched part in Figure 4), the screen synthesis mode at this time is to sort response data A from host 1 and prefetched input data B in the order of field addresses, and to If B overlaps with B, that part is B.
shall be.

When receiving a response from host 1, it is not waiting for a response and ENTE
If it is not waiting for R, it will enter normal processing, and if it is not waiting for response E
If it is waiting for NTER, the auxiliary buffer is used to perform data input processing.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to: 1) make effective use of response waiting time; 2) allow the operator to input data smoothly; and 2) shorten the time required for data input. Effects such as this can be obtained.
