Abstract

PURPOSE:To display and update the whole fields correctly with a simple operation even if a format at the time of input is not informed by providing an operation specifying means or the like for delimiting inputted data selectively into units consisting of two bytes each and specifying these unit data. CONSTITUTION:The operation specifying means or the like for delimiting the inputted data selectively into units consisting of two bytes each and specifying these units is formed. When a format program at the time of input is not informed, a ''kanji'' (Chinese character) display key 12A or 12B on a keyboard part KB12 is selectively operated and the keyed data is inputted to a control part CTL14 through a keyboard controller KBC13. Subsequently, flopply disk (FD) data is read out from a floppy disk device FDD10 through a two-byte code extracting function part KCC 14A in the CTL 14 and inputted to a ''Kanji'' code detecting part KCD15. The KCD15 checks whether the inputted two-byte code exists in font codes or not, and if exists, the two-byte code is sent and displayed to/on a CRT display part 17 as an effective code.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a character display method for a data entry machine that handles 2-byte character codes without shift codes, for example, Kanji codes without Kanji shift codes.

[Technical background of the invention and its problems]

In traditional data entry machines, such as key-to-floppy, Kanji and ANK (alphabetic, numeric, single-stage name characters)
When inputting data, you usually specify a format (togelogram) that defines the shift code attributes and start/end positions using simple parameters. In this case, the ANK data is 1 byte. /1-character display, Kanji data supports 2-byte/1-character display, so if there are a mixture of Kanji fields and ANK fields, or if there is only a Kanji field, not only when inputting data but also during input View and update completed data (
The above format program is also required when performing (updating).

Therefore, in the past, there was a drawback that if the format program for inputted data containing a mixture of 11 kanji fields and ANK fields was not known, it was not possible to correctly display and update all the fields.

[Purpose of the invention]

The present invention was developed in view of the above-mentioned circumstances, and is applicable when the format at the time of input is unknown for input data that contains a mixture of character fields consisting of character code strings with different byte units, such as Kanji fields and ANK fields. An object of the present invention is to provide a character display method for a data entry machine that can correctly display and update all fields with simple operations.

[Summary of the invention]

For example, the present invention provides a 2-byte/1-character Kanji field that does not have a Kanji shift code and a 1-byte/1-character ANK field.
For inputted data containing a mixture of fields, the data is separated by 2 bytes starting from odd digits (odd byte positions) and by 2 bytes starting from even digits (even byte positions) using a specific operation specifying means. It determines whether each of the separated two-note code belongs to the character codes that can be used in the own system, and displays and outputs characters including kanji only for the character codes that can be used in the own system. This allows all fields containing kanji to be correctly displayed and updated for data that has already been entered, even if you do not know the formatting program.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. The figure shows one embodiment of the present invention, in which a key tool 70 is shown.
Taking Tsupi as an example, the system configuration is shown in blocks. In the figure, 10 is 70 used as external storage.
70. Tsupid disk device (hereinafter referred to as FDD).
Under the control of the floppy disk controller (FDC) 1j, data is stored on a floppy disk (hereinafter referred to as FD), which serves as a storage medium, with only the ANK field consisting of a 1-byte/1-character code string, or with the above-mentioned general fields. Storing data in which a kanji field consisting of a 2-byte/1-character kanji code string is mixed, and reading the stored data on the FD 2
12 is a keyboard section (mB) which is provided with various keys necessary for normal entry operations and two specific function keys for displaying kanji characters. One of them is the first kanji display key (FKC), which specifies whether to extract the input data (data stored on the FD) in 2-byte units starting from the odd-numbered digit (first digit) of the record. , )12 A, and the remaining one is the second Kanji display key (FKC2) that specifies that the input data should be extracted in 2-byte units starting from the even-numbered digit (second digit) of the record. ) 12B. Reference numeral 13 indicates a key controller (KBC) which controls the exchange of key data between the keymate section 12 and a control section (CTL) to be described later. Reference numeral 14 denotes a control unit (hereinafter referred to as CTL) which controls the entire system of the system using microprogram control. cTL14 with
The above key receives the key manual data (7 keys) associated with the operation of the first kanji display key 11 of the one-hand section 11, and reads out the data from the FD of the FDD 10 under microprogram control. The odd-numbered digit (first digit) of the record is separated into 2-byte units and retrieved, and the data read out from the FD is read out by receiving key manual data from the operation of the second kanji display key 11B. Extract the record by dividing it into 2-byte units starting from the even-numbered digit (second digit) 2.
A separate code extraction function unit (hereinafter referred to as KCC) 14A is provided. Reference numeral 15 denotes a Kanji code detection unit (KCD) that checks whether the two-byte code extracted from KCC1'4A of CTL J4 corresponds to the font (Kanji) of the system. 16 is a CRT controller having a code/character conversion function for displaying and outputting the data (character code string) read from the FDD under the control of the CTL 14 as characters/characters.
17 is this CRT controller 1
This is a CRT display unit that displays/outputs character information turned into /zo turns under the control of 6.

The operation of one embodiment will now be described with reference to the drawings. FDD the FD where data including kanji fields have been entered 2
o, and operate the keyboard section to select update mode. At that time, if you know the format program, use that format, 2
By selecting a dobrogram or specifying the start and end positions of the kanji field, the data of each character field containing the same kanji can be transferred to CTLJ4 and CRT.
The data are displayed on the CRT display section 17 under the control of the controller 16.

Next, the Kanji field character display function according to the present invention when the format program is not known will be explained. If you do not know the format program, select update mode and press the Hansui display key 12k.
12B is selectively operated. For example, first, the kanji display key 12k is operated. When the key manual data associated with the operation of this kanji display key 12 is input to CTL l 4 via the keyboard controller 13, the KC of CTL J 4
The C14A is activated, and the FD data read by the read operation of the FDD 10 is divided into 2-byte units starting from the odd-numbered digit (first digit) of the record and sent to the Kanji code detection section 15. The kanji code detection unit 15 detects the input 2
It is checked whether the bytecode exists in the code of the font (kanji) owned by the system, and the result of the determination is notified to CTL Z 4. If the determination result of the kanji code detection unit 15 indicates "not present", the CTL 14 replaces the 2-byte code with a blank code,
Also, if it indicates 'exists', that 2-byte code is used as a valid code, and each CRT controller 1
Send on 6. Under the control of the cTL 14, the CRT controller 16 receives the above code and sends character (kanji) pattern data corresponding to the code to the CRT display section 17 for display output. As a result, only the kanji patterns corresponding to the kanji codes usable in the system are selectively displayed and output among the codes separated by 2 bytes from the first digit of the data stored in the FD. A blank display is made for the 2.guit code portion that is not used in the system. At this time, if there is a remainder in the last digit, the remaining 1-digit data is ignored.

If a satisfactory kanji display result cannot be obtained by operating the kanji display key 12A described above, then the kanji display key 12B is operated. The key data associated with the operation of this kanji display key 12B is transmitted to CTL J via the keyboard controller 13.
4, the KCC 14A of the CTL 14 divides the data j read from the FD into 2-byte units starting from the even-numbered digit (second digit) of the record and sends it to the kanji code detection unit 1.
5, and the same kanji characters as above are displayed based on the result. Therefore, the character display of the kanji field stored in the FD is as follows:
If you press one of the keys, the display will not necessarily be output. Even if you do not know the formatting program, you can easily print all characters, including kanji, with a simple key operation. Fields can always be updated correctly.

As described above, by appropriately operating the kanji display keys 121 and 12B provided on the keyboard section 12, the kanji data on the FD can be easily and easily displayed and output without the hassle of the formatting program. Furthermore, in the case of data containing only kanji fields, conventionally, it was necessary to create a format program that specifies all digits of kanji, register it, and furthermore, perform selection operations, which saved a lot of effort, but according to the embodiment described above, Kanji characters can be displayed in all fields with a simple (one or two) key operation. Furthermore, by having the kanji code detection unit 15 selectively display only the codes corresponding to the kanji fonts of the system as kanji patterns, the character data in the kanji field can be displayed in an easy-to-read manner.

In the above-described embodiment, the keyboard section 12 includes:
A kanji display key 12A for extracting the data on the FD in 2-byte units from the odd number byte and a kanji display key 12B for extracting the data in 2-byte units from the even number byte are provided separately. For example, one kanji display key is provided, and by operating that key, you specify the extraction of a 2-byte code, specify the starting digit position and ending digit position, and then select A means for displaying kanji characters separated by 2 bytes or a single kanji display key is provided, and when the key is operated once, the kanji characters are displayed from the odd numbered digits, and when the key is operated twice, the kanji characters are displayed from the even numbered digits. The present invention can also be easily realized by means etc.

〔Effect of the invention〕

As described in detail above, according to the character display method of the data entry machine according to the present invention, inputted data containing a mixture of character fields consisting of character code strings with different byte units, such as an ice field and an ANK field, can be displayed. Even if you do not know the input format, you can display and update all fields correctly with a simple operation.
