Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention constitutes an input/output terminal for an information processing system, and performs key input control and display control while sequentially interpreting a field definition table stored in a storage device inside the device. This invention relates to a display device with a functional keyboard.

Technical background of the invention and its problems Display device with keyboard (hereinafter referred to as KB/
In the KB/CRT, a field definition table consisting of one screen worth of field definition information sent from the upper processing unit is stored in the internal storage device of the KB/CRT, and the field definition information in the table is sequentially interpreted while key By providing functions to perform input control and display control, the burden of input/display control on the upper processing device can be removed.
Thereby, the processing efficiency of the entire system can be improved. In a conventional KB/CRT with such a functional configuration, key input data is stored sequentially in the internal storage device, and key input data is stored sequentially in a storage device within the device, and data is input to all fields defined by the field definition table or to multiple fields as required. When the key input is completed, the operator issues a transmission instruction, and the key input data accumulated up to that point is transferred to the higher-level processing device. The higher-level processing device performs a predetermined data validity check on these transferred data. In this case, from the operator's point of view, no error is pointed out when inputting each field is completed, input is completed for all fields requiring key input, and after the input data is transferred to the higher-level processing device. Since a validity check is performed and an error is pointed out, there is an inconvenience that input efficiency is reduced.

Purpose of the Invention The present invention makes it possible to automatically transfer the input data to a higher-level processing device when inputting each field is completed, thereby reducing the performance of the higher-level processing device and complicating the processing flow. To provide a display device with a keyboard capable of informing an operator of the result of a validity check for inputting a field immediately after the input of each field is completed without prompting the operator.

Summary of the Invention The present invention stores in advance a field definition table in which each field has transfer point designation information for instructing transfer timing in a storage device within its own device, and executes processing according to each field definition information in the table. The functional configuration is such that the transfer point of the target field is determined at a certain time, and based on the result, the input data of the target field is automatically controlled to be transferred to a higher-level processing device. Thereby, the operator can recognize the result of the validity check for the field input immediately after completing the input in each field, and the operator's input efficiency can be improved. Furthermore, since the completion of input for each field can be automatically determined and transferred to a higher-level processing device, it is possible to reduce the processing load on the higher-level processing device and avoid complicating the processing flow.

Here, the operation in one embodiment will be explained. Predefined Field Definition Table (FDT)
is from HOST-CPU200 before starting input.
Sent to KB/CRT100. KB/CRT100
Now, this field definition table (FDT) is transferred to the reception buffer 11 under the control of the reception control section 112.
3, a predetermined area (table storage area) of the internal memory 104 is stored under the control of the M-CTL 101.
Store in. In the field definition table (FDT) stored in this internal memory 104, a field number unique to that field, information such as input control, check, display control, etc., and transfer point designation information are defined for each field. ing. After sending this field definition table (FDT), the HOST-CPU200 sends the KB/CRT
An input start request is made to 100. This request signal is sent to the M-CTL 101 after passing through the reception control section 112 and the reception buffer 113. M-CTL
Upon receiving the above request signal, the field definition table 101 reads the field definition information of the field to be processed first from the field definition table (FDT) stored in the internal memory 104, and if the field requires key input, it reads the field definition information of the field to be processed first. Input control section 107
The keyboard 10 gives an instruction to accept key input to the keyboard 10.
Enable to accept key input from 3. Also, M-
The CTL 101 sets the field number at that time in the field number register 109, and further,
Transfer point information (FP) is passed to TPD 108.
The TPD 108 determines whether the given transfer point information (FP) indicates a transfer instruction,
The determination result is notified to the M-CTL 101. Here, when the M-CTL 101 receives a notification from the TPD 108 that the transfer instruction is not indicated, it writes the key input data received from the key input control unit 107 into the display memory 105 and outputs it for display on the CRT display unit 102. At the same time, it is set in the transfer buffer 110. However, in this case, if there is an instruction to hide or not transfer in the field definition information above, the above CRT
Display on display unit 102 or transfer buffer 110
No key input data is set to . Even during subsequent field processing, the internal memory 10
Field definition table FDT read from 4
If the transfer point designation information (FP) included in the field definition information does not indicate a transfer instruction as described above, the above operation is repeated.
Also, when the M-CTL 101 receives a notification from the TPD 108 indicating that it is a transfer instruction, it displays the key input data of the corresponding field and sets it in the transfer buffer 110 (however, as described above, if the field definition information is If display or non-transfer is specified, display or setting to the transfer buffer 110 is not performed), and then a transfer command is given to the transfer control unit 111. When the transfer control unit 111 receives this transfer command, it transfers the key input data stored in the transfer buffer 110 up to that time and the field number stored in the field number register 109 at that time (that is, the transfer point was specified). and
Transfer to HOST-CPU200.

As mentioned above, from HOST-CPU200 to KB/
In the field definition table (FDT) sent to the CRT100 in advance, define the points to be transferred to the HOST-CPU200.
The KB/CRT 100 detects this with its internal TPD 108 and automatically starts transferring input data to that field.

Figure 2 shows part of the processing flow when the HOST-CPU 200 receives transfer data.Here, the condition is that the field number notification (f) in which the transfer point is specified is in which field. This shows that it is possible to develop a simple flow that branches out to a check flow for each point. When an error is detected in each of these checks, the error detection information is sent to the KB/CRT10.
Under the control of the M-CTL 101, the display control section 106 causes the CRT display section 102 to display and output the error message. This allows the operator to know of input errors immediately after key input for each field.

Effects of the Invention As detailed above, according to the display device with a keyboard of the present invention, a field definition table defined for each field including transfer point designation information is stored in advance in the self-device, and the field When executing processing according to the contents of the table, the contents of the transfer point specification information in the relevant field are judged, and when it is determined that there is a transfer point specification, the data keyed in up to that time is automatically sent to the higher-level processing device. By adopting a configuration that allows transfer control, the performance of the upper processing unit is not degraded, the processing flow within the upper processing unit is simplified, and the error status is immediately notified to the operator for each field unit input. This makes it possible to improve operator input efficiency.
