Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing device,
Specifically, it has a keyboard and a display, and indicates the input position by displaying the cursor on the display screen of the display to perform key input, create a database file having multiple fields, and display it by the input format program. The present invention relates to a data processing device configured to input data to the file on a data input screen.

[0002]

2. Description of the Related Art In this type of data processing device, when data is input to a database file created on a display screen of a display, the cursor on the display screen is moved to the beginning position of a desired field to input the data. To do.
Conventionally, the cursor can be moved back and forth by one digit or continuously by operating a so-called cursor key or the like, and can also be moved back and forth in field units and further back and forth in record units.
There is also known a configuration in which a cursor can be skipped in a plurality of fields and moved backward in response to a key input of a special key called a group skip key.

[0003]

By the way, depending on the use of the database file, the record length is, for example, 1K.
Although it is longer than byte and has a large number of fields, the number of fields to be left blank is large and the number of fields to which data is always input may be small. When data is input to such a database file and the cursor is moved to the field at the end of one record, it will be at the beginning of the record or at the beginning of the field in which data must be entered. In order to return the cursor, conventionally, it is necessary to perform a plurality of key operations for returning the cursor in field units while looking at the display screen of the display. This imposes a heavy burden on the operator, and data input cannot be performed efficiently.

Therefore, an object of the present invention is to solve such a problem, improve the operability of this type of data processing apparatus, and allow an operator to efficiently input data in a database file. ..

[0005]

In order to solve the above problems, according to the present invention, in a data processing device of the above type, the cursor on the display screen of the display is returned to the head position of a predesignated field. When the back key for inputting commands and data input to the database file are input, the display on the display is displayed so as to return the cursor to the head position of the field in which a predetermined mark is set in advance in the input format program according to the input of the back key. A structure provided with a control means for performing the operation is adopted.

[0006]

With this structure, when the data is input to the database file, the cursor can be returned to the head position of the desired field designated in advance by setting the mark just by operating the back key once. ..

[0007]

Embodiments of the present invention will be described below with reference to the drawings. First, the schematic configuration of the data processing apparatus of the embodiment will be described with reference to FIG.

In FIG. 1, reference numeral 3 is a CPU (Central Processing Unit) composed of a microprocessor or the like which is the main body for data processing, and a keyboard 1 and a magnetic disk for an operator to input data to the CPU 3. An external storage device 2 such as a device, a ROM (read only memory) 4, a RAM (random access memory) 5, a display 6 for displaying data, a printer 7 for recording and outputting, etc. are connected.

The CPU 3 executes a program stored in the ROM 4 or a program transferred from the external storage device 2 to the RAM 5 to execute processing such as creation of a database file and data input to the file according to an input from the keyboard 1. Then, the display 6 is made to perform the necessary display. When a command for recording and outputting data is input from the keyboard 1, the CPU 3 drives the printer 7 to perform recording and output.

By the way, the point that the apparatus of this embodiment is different from the conventional one is that a designated back key 1a is provided on the keyboard 1, and when this key 1a is pressed at the time of data input to the database file, the cursor on the display screen of the display 6 is moved. It is returned to the head position of the desired field designated by the operator in advance (hereinafter referred to as "designated back"). The start position of the desired field is set by setting a predetermined mark in the desired field in the input format program that displays the data input screen for the database file.

Details of the configuration for such a designated bag will be described with reference to FIG.

FIG. 2 schematically shows the contents of processing by the program of the CPU 3 relating to the designated back. In FIG. 2, a control program 8 is a program for performing basic control of the entire apparatus including input / output control of peripheral devices such as the keyboard 1 and the display 6, and is a so-called operating system.

The entry program 9 is a program for performing various data processing such as creating a database file, inputting data to the file, changing data and deleting data.

Further, the input format program 10 is a program for displaying on the display 6 a data input screen for inputting data to the database file. This program 10 is created as desired by the operator's key input using a general editor program or a program for creating an input format program included in the entry program 9.

The data of the input format program 10 includes the designated back position information and the normal position information shown in addition to the format data such as the field name of each field, the data format such as alphabet or numerical value, and the length of the data. .. Here, the designated back position information is the information of the position where the designated back should be performed, and the normal input position information is the information of the normal input position where the designated back is not performed. The designated back position information is given when the operator sets a predetermined mark, for example, a "#" mark, at the beginning position of a desired field to be designated back when the input format program 10 is created.

Such an input format program 1
An example of the input format of 0 is shown in FIG. Where "A" is the alphabetic data format,
"N" is a numerical data format, the length of "..." is the data length,
“E” indicates the end of one record, and “#” is the mark at the beginning position of the field to be designated back as described above. Note that the designated back position may be set at one place by the symbol “#”, or may be set at a plurality of places.

Assuming that the input format is set in this way, when inputting data to the database file, the operator inputs "ABCD" data in the first field by key operation as shown in FIG. 3 (b). Then, if the designated back key 1a is pressed after moving the cursor to the fifth field, as shown in (c), the cursor is set to the second mark marked with "#" in the format of (a). It is possible to return to the head position of the field and immediately input data to the second field.

Next, the details of the processing by the program of the CPU 3 for realizing such a designated back will be described.

In FIG. 2, when there is a key input from the keyboard 1 (step S1), the key input analysis program in the control program 8 analyzes the key input to create key input information, and the entry program is created according to the input information. 9 is called (step S2).

If the key input is the input of the designated back key 1a, the entry program 9 analyzes the input format program 10 (step S3), and retrieves the designated back position information to which the cursor should be returned at the designated back (step S3). Step S4).

In this case, in detail, as shown in FIG.
Alternatively, a plurality of designated back position information is read (step S11), the designated back position information is compared with the current cursor position information (step S12), information of the designated back position immediately before the current cursor position is taken out, and the cursor is returned. Control program 8 as information on the designated back position to be used
(Step S13, step S5 in FIG. 2).

The control program 8 having received the designated back position information controls the display 6 so as to change the display position of the cursor on the display screen of the display 6 to the designated back position based on the information (step S6). As a result, the position of the cursor on the display screen of the display 6 is returned, for example, from the position (1) in FIG. 2 to the position (2), or as shown in FIG.
Will be returned to the position of (c).

As a result of the comparison in step S12 of FIG.
If there is no information on the designated back position before the current cursor position, the process may be terminated as it is, or an alarm indicating that the designated back key 1a is erroneously operated may be output.

According to the present embodiment as described above, when the data is input to the database file, the operator only needs to operate the designated back key 1a once to return the cursor to the head position of the desired designated field. Can
Moreover, at that time, the back position of the cursor is not erroneous even if the display screen is not viewed. Therefore, the burden on the operator of key operations can be greatly reduced, and data input can be performed efficiently.
