Abstract

PURPOSE:To improve an input operation without losing the processing speed by providing a function to identify an item up/down shift key and to define a field right above or right under the input field as a next field. CONSTITUTION:The program of CPU1 issued the demand to start to the control means 23 instructing position and length of each field, identification of unfixed or fixed field group to be displayed to a display 3, and in case of fixed field, factors of field number which constitutes the two dimensional table. The means 23 identifies the item advance or retreat keys in addition to the identification up and down keys and delivers such information to an arithmetic means 22. The means 23 specifies not only the fields immediately back or prior to the already input field but also the fields right under or above as the next input field, and informs to an output action means 21 through the means 23. According to this information, the means 21 executes input processing from the field on the screen of a device 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a simple input device for a feed group displayed on the screen of a display device in a workstation or the like.

[Technical Background of the Invention] Conventionally, there has been a field mode on the screen of a display device with a keyboard such as a workstation.

The idea is to set several fields, which are the minimum input/output units, anywhere on the screen, and input/output data to those fields. The input processing order in such field mode input processing is performed in ascending/descending order of field numbers sequentially assigned to each field. That is, when the input of the nth field is completed, the item advance key or the item end key provided on the keyboard attached to the display device is pressed to enable the input of the n+1th field next, or to input the item backward. By pressing a key to enable input to the nith field next, input processing fields are selected one after another and input processing is performed. Here, the above set of fields is an amorphous field group A in which each field is shown individually as shown in FIG.

It can be classified into a fixed field group B in which a plurality of fields constitute a two-dimensional table. In addition, the numbers assigned to the irregular field group A and the regular field group B in the figure are 1.2.3.
and (1, 1>(1, 2>...) indicate field numbers assigned to each field in order.
White arrows indicate the movement direction of the item forward and backward keys, and black arrows indicate the movement direction of the item up and down movement keys.

FIG. 3 is a block diagram showing an example of a conventional input/output device for field groups on a display screen. In response to a program output request, the output start field number and output data sent from the external central processing unit (CPU) 1 are displayed on the screen of the display device 3 via the input/output operating means 21 of the input/output device 2. Ru. In a program input request, the CPUI notifies the input start field number to the input/output operation means 21,
The input/output operation means 21 performs input processing according to this notification. Furthermore, this input/output operation means 21 converts input data into CPI
At the same time, upon completion of data input from one field, the press of the item forward or item backward key to designate the next input field is identified and sent to the calculation means 22. The calculation means 22 analyzes the type of item completion key based on the data from the input/output operation means 21, determines the field position to be input next, and returns it to the input/output operation means 21.

The input/output operation means 21 repeats the input request for the field notified from the calculation means 22.

In the amorphous field group A described above, the input/output operation means 2
1 identifies the pressing of the item forward and item backward keys, determines the next input field in this input/output device 2, and performs input/output processing in ascending/descending order of field numbers.

[Problems with Background Art] Next, in the above-described fixed-form field group B, if input processing is performed in ascending and descending order of field numbers, that is, in the order indicated by the white arrows in FIG. Group A1
．． : The operation is the same as in .

However, as shown by the black arrow in FIG. 2, if you want to move the input field directly below or directly above, the 1, 1 person output operation means 21 cannot distinguish between the item down movement key and the item down movement key press. Conventionally, this identification and the determination of the next input field in this case were performed by the CPtJl program.

Therefore, there is a drawback that the load on the CPU 1 increases, and the information processing speed of the system as a whole becomes slow.

[Object of the Invention] In view of the above-mentioned drawbacks, the object of the present invention is to provide a method for moving the next input field to any field in the front, back, and top directions centering on the adult cuff field without placing a burden on an external central processing unit. The object of the present invention is to provide an input/output device for fields on a display screen that can be used to input and output fields on a display screen.

[Summary of the Invention] The present invention provides an input/output device that inputs and outputs data to and from a group of fields on a display screen. A control means that can also identify the pressing of the item upper and lower movement keys, and a calculation means that determines the next input field based on the identification of the pressed keys from this control means. The above object is achieved by configuring that the movement process is also performed within the input/output device.

[Embodiment of the Invention] Hereinafter, an embodiment of the present invention will be described with reference to the drawings, in which the same parts as those of the conventional example are denoted by the same reference numerals. FIG. 1 is a block diagram showing an embodiment of an input/output device for field groups on a display screen according to the present invention. The input/output device is input/output operation means 2
1, a control means 23 and a calculation means 22. The input/output operation means 21 inputs and outputs data to and from fields displayed on the screen of the display device 3.

The control means 23 requires use from a program in the CPUI,
It consists of a flip 70 tab that accepts requests and a memory that stores input data, and sends and receives data to and from the CPU. The calculation means 22 stores the number of horizontal elements and the number of vertical elements for the fixed-form field group, and when inputting a field, calculates the next input based on the type of item completion key (referring to item forward, backward, and item up and down movement keys). It consists of a flip-flop that determines the field position.

Next, the operation of this embodiment will be explained. First, CPU1
This program identifies the position and length of each field to be displayed on the display device 3, as well as the identification of amorphous fields and fixed-form field groups, and the field numbers of elements constituting a two-dimensional table in the case of fixed-form field groups. A start request instructing the control means 23 is made to the control means 23. In response to this request, the control means 23 stores the meaning of the field to be displayed, and when a fixed form field group is specified, notifies the calculation means 22 of information on this fixed form field group. Based on this notification, the calculation means 22 calculates the number of horizontal and vertical elements of the table and the table start field number (
1, 1> is stored. However, please refer to Figure 2 for the starting field number of this table. Next, when the CPU program requests the control means 23 to output data to the display device 3, the control means 23 sends the output start field number and output data to the display device 3 via the input/output operation means 21. The FeelBee group and output data are displayed on the screen of the display device 3 (see Figure i2).

Next, when the CPU program makes an input request to the control means 23, the control means 23 notifies the input start field number to the input/output operation means 21.
1 performs input processing from fields on the screen of the display device 3 in accordance with this notification. As a result, input data and item completion key press data (item forward, backward, and item up and down movement keys) pressed by the operator on the keyboard of the display device 3 at the end of the input process are returned to the control means 23. . The control means 23 stores the input field number and input data, identifies the item completion key, and notifies the calculation means 22 of this.

The calculation means 22 analyzes the type of item completion key sent, and if it is within the amorphous field group, replaces the field with the field number before or after the field number assigned to the already input field as the next field. Perform the operation to determine the input field, and select the field to be input next from the number of horizontal and vertical elements of the table already stored in this calculating means 22 as described above if it is a fixed form file (□” yield group). An operation is performed to determine the position.At this time, the control means 23
It goes without saying that it can identify the key types of item forward and item backward, but it can also identify the key types of item up and down. As shown, for example, if the already input field number is (2, 2), the field number (1, 2>) or the field number (
The field 3, 2> can be determined to be the next field to be input. The next field input position determined by the calculation means 22 is notified to the control means 23, and the control means 23 issues an input request to the notified field through the input/output operation means 21 in the same manner as described above. The subsequent operation is a repetition of the above operation, and in the case of fixed field group B, the increment of the already input field number and the field immediately above or below this field can be used as the next input field. When the input in each field on the screen of the display device 3 is completed, the control means 23 notifies the CPtJl program of the input field number and the corresponding input data.

According to this embodiment, the control means 23 not only identifies the item forward and backward keys, but also identifies the item up and down movement keys, and in response to this, the calculation means 22 not only identifies the fields before and after the already input field, but also the fields immediately above it, Since the field immediately below is determined to be the next input field, the input field can be moved in the four directions without placing a burden on the CPU 1.

Therefore, the operability of inputting to the field group can be improved without sacrificing the information processing speed of the entire system.

[Effects of the Invention] As described above, according to the input/output device for field groups on a display screen of the present invention, in addition to the item forward and backward keys, keys for moving input fields are used in input processing for a fixed-form field group. and a control means that also identifies the key presses for moving up and down the item.

a calculation means that determines a field in the front and back directions of the input field to be the next input field based on the keystroke identification from the control means, and notifies the control means of the result; By having an input/output operation means that performs input/output processing to fields on the screen based on commands from the first stage, the next input field can be input to the adult without placing a burden on the external central processing unit. It has the effect of being able to move to any field in the front, back, up and down directions around the cuff field.
