DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a keyboard display device for inputting and displaying alphanumeric characters and Arabic codes.

(Prior Art) Conventionally, in a keyboard display device that inputs and displays alphanumeric characters and Arabic codes, the code input from the keyboard and used in data processing and the characters displayed on the display device have a one-to-one relationship. Corresponding or 1.2 to 0 for numeric numbers
It was displayed in alphanumeric numbers, but not in Arabic numbers.

[Problems to be Solved by the Invention] The conventional display device described above has, for example, 0
．． Alphanumeric numbers 1 to 9 only 1:1
This has the disadvantage that it is difficult for people who use some Arabic characters to read the code, and in order to display numeric and Arabic numbers, the code used in general data processing systems has to be If you add Arabic numerals to support the =1 code, general data processing equipment will only process alphanumeric numerals as numbers, so if you set it to a code that does not correspond to the EBCDI (: code number) on a general data processing equipment, for example, The disadvantage is that Arabic digits cannot be processed like alphanumeric digits.

(Means for Solving the Problems) The Arabic processing device of the present invention has an input means for inputting characters, a display means for displaying the input characters, and a file means for storing the input characters as data. In the processing device, a terminal control unit that outputs input characters to a file means or sends them to a display means, a key storage buffer that stores input character codes,
an Arabic field specifying section that stores the processing mode of the input character code; a character address converting section that selects the character address to be displayed on the display means; and a character address converting section that outputs the character code and the processing mode to the character address converting section. It has an Arabic field conversion section that inputs a character address from the conversion section, a screen buffer that stores the character address corresponding to the display screen, and a screen control section that generates a corresponding character from the character address of the screen buffer.

In the present invention, both numeric numerals and Arabic numerals can be displayed on the display means, and both numeric numerals and Arabic numerals can be stored as the same data in the file means.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the Arabic processing apparatus of the present invention.

The keyboard 1 is used to input characters, numbers, etc. to be created, and has alphanumeric, upper symbol, lower Arabic, upper Arabic mode keys, tab keys, etc., and each character code can be input by specifying a mode. The input character code sent from the keyboard 1 is temporarily stored in the key storage buffer 3. The Arabic field designation section 4 has field functions corresponding to one screen of the display device 9, such as the keyboard 1.
The mode designation codes sent from , ie alphanumeric, upper symbol, Arabic lower, and Arabic upper mode, are temporarily stored. The terminal control unit 2 is a part that controls the keyboard 1, display device 9, floppy disk IO, etc., and transfers the character code input from the keyboard 1 to the key storage buffer 3 so that it can be converted into an appropriate display character address. At the same time, the character code is output to the floppy disk 10 as necessary. The Arabic field conversion section 5 inputs the input character code to the character address conversion section 6 in order to determine the character address to be displayed on the display device 9 according to the input character code of the key storage buffer 3 and the mode specification code of the Arabic field specification section 4. and the mode specification code, and receive the converted display character address. The character address conversion unit 6 receives the input character code and mode designation code such as Arabic upper mode from the Arabic field conversion unit 5, and converts the display in the screen control unit 8 using the internal character code address conversion table for display display characters. Generates a character address corresponding to the display character generation unit address. The screen buffer 7 is a general display buffer that stores display character addresses sent from the Arabic field converter 5. The screen control unit 8 reads the character address for display display stored in the screen buffer 7, generates the corresponding character from a character generator (not shown), and displays it on the display device 9 in synchronization. This is a screen control section.

Next, the operation of this embodiment will be explained.

The operator presses a mode designation key on the keyboard 1 to set, for example, an Arabic lower key mode for the character he or she wants to input. Next, enter the Arabic letters or non-numeric digits you want to enter.

The input characters are sent to the floppy disk 10 and the display device 9 via the terminal control section 2. Arabic lower key mode is Arabic field specification part 4
Character codes such as Arabic characters or Arabic numerals are respectively stored in the key storage buffer 3. A character address for display is generated by the character address converter 6 according to the character code and the Arabic lower key mode. In the case of Arabic numerals, the character addresses are in the form of Arabic numerals for display, and are sequentially shifted from left to right and input into the screen buffer 7.

In the case of Arabic characters, the corresponding character addresses are in the form of Arabic characters, which are sequentially shifted from right to left and input into the screen buffer 7. In addition, in the case of alphanumeric mode, the numeric number becomes the corresponding character address in the form of a numeric number for display, and is sequentially shifted from left to right and stored in the screen buffer 7.
is input. The alphabetic characters become corresponding character addresses in the form of alphabetic characters for display, and are sequentially shifted from left to right and input into the screen buffer 7. Screen buffer 7
The character address entered is read by the screen control section 8, and the corresponding character is generated by the character generator and displayed on the display device 9. Furthermore, the characters input by the operator are displayed on the display device 9 and output to the floppy disk 10 in the form of an EBCDIC code. The character code of the Arabic lower key mode and the Arabic numeral, or the character code of the numeric numeral in the case of the alphanumeric mode, is sent to the terminal control unit 2. The terminal control unit 2 inputs both the character code of Arabic numerals and the character code of numeric numerals, the numeric code of EDfl:DIC code of floppy disk lO,
For example, 0 is converted into a hexadecimal code of FOll is Fl, and 9 is converted into a hexadecimal code of F9 and output to the floppy disk IO.

〔Effect of the invention〕

As explained above, the present invention provides an Arabic processing device that processes Arabic characters, outputs numeric numerals and Arabic numerals to a file means with the same code, and outputs numeric numerals and Arabic numerals separately to a display device. By displaying the information, the following effects can be achieved.

■ Operators can now enter data from the keyboard in the form of Arabic numerals, making it easier to see the input keys, reducing input errors, and improving input speed and operability.

■ Since the operator can immediately see the Arabic numerals entered from the keyboard on the display device, the displayed characters are easy to see and visually check, improving input speed and operability.

■ Since the numeric numbers and Arabic numbers output to the floppy disk are the same code, for example, even if you program the numbers in Arabic characters in a Kobol program and input them from the keyboard, they will not work as EDCDIC codes on a general data processing device. This improves program productivity and data entry.
