Abstract

PURPOSE:To avoid such a case where the input numerals remain partially in an input mode of numerals, by updating the contents of a document memory means according to the number of data stored in a memory means. CONSTITUTION:The value of a present cursor column address CRX is transferred to a work register RA and decided for transfer the contents of a numeric buffer (NBUF) to a document memory (DBUF). If the valid numeric data is available, the numeral of the lowest digit shown by a numeric counter NBC in the buffer NBUF is transferred to the memory DBUF. here the transfer position is indicated by a cursor row address CRY and the register RA. Then '1' is subtracted from the register RA and also from the counter NBC. These processes are repeated to transfer completely all numeric data stored in the buffer NBUF to the memory DBUF.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a character processing device for inputting and editing characters, and particularly to a batch input of data such as numbers.

[Conventional technology]

Conventionally, some character processing devices of this type are equipped with a decimal tab key in order to align the scale of input data, such as numeric data. After moving the cursor to the desired position using the decimal tab key, part of the input numerical data is stored in the line memory, and the numerical data input so far is transferred to the document memory or display memory, etc. display and print.

In other words, the data that has been input is stored and transferred all at once to the document memory.

[Problem that the invention seeks to solve]

However, in such a device, when, for example, numbers have already been input and the number of new numbers to be input is small,
There was a problem in that some of the numbers that had already been entered remained and were connected to the newly entered numbers.

[Means for solving problems]

In order to solve this problem, the present invention includes a storage means for storing data and a document storage means for transferring and storing data.
A control means is provided for updating the contents of the document storage means according to the number of data stored in the storage means.

[For production]

The contents of the document storage means are updated according to the number of data stored in the storage means, so that already input data and newly input data do not connect or overlap.

are doing.

FIG. 8 is a main flowchart showing this embodiment. FIG. 9 is a detailed flowchart of process 4 in FIG.
It shows the flow of processing for transferring the contents of the numeric buffer/NBUF to the document memory DBUF.

The embodiment carried out with the above configuration will be described in detail with reference to the flowcharts of FIGS. 8 and 9, and how the state changes from the initial state diagram of FIG. 5 to the state of FIG. 7.

In the flowchart of FIG. 8, in process 1, initial settings are performed when the power is turned on, and devices connected to the common bus BUS are made available for use. In this embodiment, initial settings, character input, etc. are implemented using known techniques, so detailed explanations will be omitted.

Random access memory lJRAM in this embodiment
The initial value in decimal Φ mode φ flag DTM=O
, numeric buffer counter NBC=O, and the contents of numeric buffer NBUF are all O. The cursor is 3 digits,
Assume that it is in column 10, column address CRX=IO, and row address CRT=3.

Next, in process 2, key input is performed, and subsequent judgment process 2
．． 1 to 2.4 select the process corresponding to each key. When the cursor key 〇K is input, processing 3 is selected by 1 judgment processing 2.1, and in processing 3, the column address CRX and row address C are selected depending on the moving direction of the cursor.
Change RY to determine the position to display the cursor. In this embodiment, column address CRX=10, row address CRY
=3.

Next, when the decimal key DTK is input, judgment process 2
．． 2, processing 4 and processing 5 are selected. In process 4, the process shown in the flowchart of FIG. 9 is performed.
In this embodiment, as the initial state, the number buffer counter NBC is set to O, so in the 0th order processing 6, which is not processed according to the judgment processing 4.1, 1 is stored in the decimal input mode flag DTM, which will be described later. Enables accumulation in the number buffer NBUF by process 8.

Next, when numerical data is input, the decimal input mode flag DTM is 1 in 1 judgment process 2.3, so judgment process 2.4 is selected.

Here, when the decimal input mode flag DTM is O, process 6 is selected, and in the 0 judgment process 2.4, normal character input/editing is performed, when the decimal input mode flag DTM is 1, the input is Determine whether the entered character is numeric data or non-numeric data. If it is numeric data, add 1 to the numeric buffer counter NBC and store the input numeric data in the numeric buffer NBUF.0 In this embodiment, as shown in FIG. is 5. Process 7 shows the process when characters other than numeric data are input, and by storing 0 in the decimal input mode fist flag DTM, it is instructed to stop storing in the numeric buffer NBUF, and the numeric buffer is・Counter N
By setting BC to O, the number buffer NBU is already
If there is numerical data stored in F, it will be invalidated.

Thereafter, in process 6, the input characters are stored in the document memory DBUF.

Next, by process 8, the number buffer N is set as shown in FIG.
When the decimal fist key DTK is input again with BUF and number buffer counter MBC set, processing 4 and processing 5 are selected by determination processing 2.2.

In process 4, the numerical processing shown in the flowchart of FIG. 9 is performed, and from the state of the document memory DBUF of FIG.
As shown in the figure, the contents of the number buffer NBUF are transferred. To explain in detail, in determination process 4.1 in FIG. 9, the number buffer counter MBC is determined, and the process proceeds to process 4.2 only if a valid number exists in the number buffer NBUF; otherwise, no processing is performed. becomes.

In process 4.2, the column address CRX of the current cursor position is
0 plus 1 to the work register RA.
In the next determination process 4.3, it is determined whether the character in the document memory DBUF indicated by the line address CRY at the current cursor position and the work register RA is a number. If it is a number, in the next process 4.4, the number data is replaced with a space and 1 is added to the work register RA. The above processing is repeated until a character other than numeric data is detected. This process erases the input numerical data following the right side of the transfer destination cursor position.

If a character other than numeric data is detected in judgment process 4.3, perform the following processes 4 and 5. Here, the data is transferred from the cursor column address CRX to the numeric buffer (Number) NBC.
and sets the result in work register RA. In the embodiment, cursor column address CRX=10
.

Since the number buffer φ count MBC=5, 5 is set in the work register RA.

In the next judgment process 4.6, the document memory DB specified by the work register RA and the cursor row address CRT is
Determine whether the character data of UF is numeric data. If it is numeric data, in process 4.7, it is replaced with a space and 1 is subtracted from work register RA. By repeating this process, the numeric data on the left side of the transfer destination is erased. If a character other than numeric data is detected, proceed to the next process 4.7.

In processes 4 and 8, the value of the current cursor column address CRX is transferred to the work number register RA. Next judgment process 4.9
Now, transfer the contents of the number buffer NBUF to the document memory DBU.
If there is valid numeric data to be determined for transfer to F, process 4.10 and processes 4 and 11 are selected. In process 4, '10, the lowest digit number indicated by the number buffer φ counter NBC in the number buffer NBUF is transferred to the document memory DBUF. The transfer position is indicated by the cursor line address CRY and the work register RA. In the next processes 4 and 11, subtract 1 from the work register RA, and then subtract 1 from the numerical buffer counter NBC. Repeat the process for 0 or more. As a result, all the numerical data stored in the numerical buffer NBUF is transferred to the document memory DBUF.

With the above process 4, the left and right sides of the inputted numbers in the transfer destination document memory DBUF are erased, and the contents of the number buffer NBUF are transferred.

In the above embodiment, only when inputting numbers,
I try to erase the numbers that have already been entered so that they do not connect, but in Roman character processing devices, words are separated by spaces, so when re-entering over a word that has already been entered, the spaces before and after it are deleted. You may also delete the word and transfer the new word.

That is, in the embodiment, only numbers are processed, but it is also possible to process character data including plus/minus signs, decimal points, stacking cutoff symbols, etc.

In addition, if the judgment is Yes in judgment processes 4 and 3 or processes 4 and 6 in FIG. - Lower the line on the target document memory DBUF by one line, or use the document memory DB indicated by CRY.
The present invention is effective even if one line of data on the UF is moved down by one line.

As described above, according to the present invention, it is possible to prevent part of the inputted numbers from remaining when inputting numbers, and to reduce the burden of inputting work, especially when handling a large number of numbers such as in a numerical table. This has the effect of eliminating mistakes.
