Abstract

PURPOSE:To suppress the generation of a misoperation by giving a notice to an operator by a buzzer sound, etc., in case when a business program data has been stored in an internal storage part. CONSTITUTION:When a program number of one business program is brought to a key input by a business selecting key 16, first of all, whether other business program data which is being executed already is stored in a program area in an RAM 4 or not is checked. Also, a capacity of an idle area in which the business program data is not stored yet, in the program area of this RAM 4 is checked. If the business program data concerned can be stored in the idle area, the business program data of the program number concerned is read out of a floppy disk recording device 10 and stored in the idle area of the program area of the RAM 4. Also, a buzzer 6 outputs a confirmation sound.

Description

[Detailed Description of the Invention] [Industrial Application Field] Second, the present invention is a data management device that reads out one or more business program data stored in an external storage unit, temporarily stores the data in an internal storage unit, and then simultaneously executes the data. Regarding.

[Prior Art] In a computer system, multiple types of business program data are stored in advance in an external storage unit such as a floppy disk recording device, and necessary data are stored by key input operation of a business selection key provided on a keyboard. There is a system in which business program data is read out from the 70-bit disk recording device, temporarily stored in an internal storage unit such as a RAM, and then executed. Usually, in such a computer system, a plurality of business programs are executed simultaneously under time-sharing control.

[Problems to be Solved by the Invention] However, as described above, the data management device for a computer system that can simultaneously execute a plurality of business programs has the following problems that still need to be improved. In other words, even if an operator inputs a task selection key on the keyboard to execute a new business program while the computer system is already running a large number of business programs, the business program in internal storage such as RAM will be deleted. If the previously selected and running business program is already stored in the storage area and there is no empty space,
Business programs cannot be executed. However, in conventional data management devices, even if the business program selected by the job selection key is not stored in the internal storage as described above and the business program does not start running, the operator can There was no way to check whether the business program was actually executed until checking whether the final result of the program was output. As a result, the operator feels very anxious until the execution results of the selected business program are output.

In addition, since it is not possible to immediately confirm that the business program is being executed reliably, the operator may become anxious and may press the wrong key again or press the wrong key.

The present invention has been made based on the above circumstances, and its purpose is to store the business program data selected by the selection key in the internal storage section when the business selection key is input. If an error occurs, the data management device notifies the operator with a buzzer, etc., so that the operator is immediately informed that the business program has started execution, giving the operator a sense of security and preventing the occurrence of erroneous operations. It is about providing.

[Means for Solving the Problems] The present invention provides a method for selecting one of a plurality of types of business program data stored in an external storage unit by a key input operation of a business selection key provided on a keyboard. After storing three or more business program data in the internal storage unit,
In a data storage device that simultaneously executes each business program, in response to a key input operation of a business selection key, there is an empty area in the internal storage section to store the business program data selected by this key input operation. If there is an empty area, the business program data selected by the job selection key is stored in this empty area, and it is notified that this business program data has been stored in the internal storage. This is what I did.

[Function] With a data management device configured in this way, when an operator inputs a specific job selection key to execute a job program, there is an empty area in the internal storage and the job selection key is filled in. When the selected business program data is stored in the internal storage and the business program starts running, the operator is notified by, for example, a buzzer.
Immediately after operating the job selection key, the operator can confirm that the corresponding job program has started executing.

[Example] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a computer system incorporating a data management device according to an embodiment.

1 in the figure is a CPU (central processing unit) that executes various information processing based on data input from a keyboard etc.
This CPU I is connected via a path line 2 consisting of a data bus and an address bus to a ROM that stores fixed data such as control programs that are the basis of this computer system.
(Read-only memory) 3. RAM 4 which temporarily stores variable data such as each business program data. A keyboard interface 7, CR receives key input signals from the keyboard 5 for key inputting various control commands and various data, and sends drive signals to the buzzer 6.
7 Display unit interface 9 for sending display data to display unit 8. It also controls the disk interface 11, etc., which sends and receives data to and from the floppy disk recording device 10 in which a plurality of business program data are stored.

As shown in FIG. 3, the keyboard 5 has a large number of keys arranged for inputting various command codes and data. 12 in the figure is a character key for inputting various command codes, and a cursor 13 displayed adjacent to this character key 12 on the display screen of the CR7 display section 8 shown in FIG.
Cursor key to move 14. Numerical keys for entering data numbers 15. Floppy disk recording device 1
For example, business selection keys 16 of 1 to 15 are arranged to select the program number of each business program read from 0 and displayed on the display screen of the CR7 display section 8.

The floppy disk recording device 10 includes, for example, 15 disks.
A floppy disk on which various types of business program data are pre-recorded is set, and each of the 15 business program data recorded on this floppy disk can be read out at any time by a read command from the CPU 1 via the disk interface 11. Ru.

In addition, the RAMJ has an area for temporarily storing various commands and various data inputted from the keyboard 5.
A program area is formed to store each business program data read from the floppy disk recording device 10 by a read command from the CPU 1.

Further, the CR7 display unit 8 displays the names of each of the 1 to 15 business programs stored on the floppy disk as described above, and also displays the execution results of each business program.

When the operator inputs a predetermined specific display key on the keyboard 8 to execute a new business program, the CPLJl is transferred to the floppy disk recording device W110 via the disk φ interface 11.
A read command for the names of business programs 1 to 15 recorded on the floppy disk and the program capacity to be used is sent. When the business program names 1 to 15 and the program capacity are read out, each business program name is displayed on the display screen of the CR7 display unit 8 via the display unit interface 9 as shown in FIG.

Then, the operator looks at the business program names 1 to 15 displayed on the display screen of the CR7 display section 8 and enters the program number 1 to 15 of the business program name to be executed using the business selection key 1 on the keyboard 5. When a key is input at , the CPU 1 is configured to start executing the corresponding business program according to the flowchart shown in FIG. That is, when the program number of one business program is keyed in using the business selection key 16, other business programs that are already being executed are first stored in the program area in RAMJ.

Check whether data is stored. If one or more business programs have already been stored, the capacity of the empty area in the program area of this RAM 4 where no business program data is stored is checked. Then, if the empty area is larger than the program capacity of the business program corresponding to the input program number, it is possible to store the corresponding business program data in this empty area. The business program data of the corresponding program number is read from the recording device 1110 and stored in an empty area of the program area of the RAM 4.

Note that if no other business program data is stored in the program area of the RAM 4, the business program data of the corresponding program number is immediately read from the 70 disc recording device 10 and stored in the program area of the RAM 4.

When the storage of the 19 grams of the relevant business in the program area of the RAM 4 is completed, and after confirming that no writing errors have occurred, a drive signal is sent to the buzzer 6 via the keyboard interface 7 to start the selected business program. A confirmation sound indicating that the program has been properly stored in the program number area of the RAM 4 is output. When the output of the confirmation sound is finished, the execution of the business program newly stored in the program area of the RAM 4 is started.

Note that if the capacity of the free space in the program area of RAM4 is smaller than the program capacity of the business program to be newly executed, it is impossible to store a new business program in the program area of RAM4, so the flowchart will continue as is. terminate.

With a data management device for a computer system configured in this way, while the computer system is already running a large number of business programs, an operator can enter the program number of the business program in order to execute a new business program. When a key is input using the selection key 16, if there is still an empty area in the program area of the RAM 4 that can store new business program data, this new business program data is stored in the corresponding empty area, and the buzzer 6 is activated. makes a confirmation sound.

Then, a new business program starts running.

On the other hand, if there is no longer an empty area in the program area of the RAM 4 to store a new business program, the buzzer will not sound and the new business program will not be executed.

In this way, the operator can immediately confirm whether or not the business program selected and set using the business selection key 16 is properly stored in the RAM 4 and started to be executed at the time of key input operation of the business selection key 16. It is possible. Therefore, the operator can feel at ease because he or she does not have to worry about whether or not the business program input by key has actually been executed, and there is no fear that the operator will press unnecessary keys due to anxiety. As a result, the occurrence of erroneous operations on the keyboard 5 can be suppressed.

Note that the present invention is not limited to the embodiments described above. In the embodiment, the buzzer 6 is used as a notification means to notify that the business program has been properly stored in the RAM, but it may also be displayed on the display screen of the CRT display section 8 on that day. Further, it may be displayed using a display lamp or the like.

[Effects of the Invention] As explained above, according to the present invention, when a business selection key is input, a buzzer sounds if the business program data selected by the selection key is stored in the internal storage. etc., to notify the operator. Therefore, the operator can immediately confirm that the execution of the business program has started, allowing the operator to work with peace of mind and preventing the occurrence of erroneous operations.
