Abstract

PURPOSE:To improve the flexibility of a calculating function in the case of executing search or sort by providing the means for calculating a numerical value to be processed while ignoring the modifying attribute in the case of executing a command. CONSTITUTION:When a search command start key SSKEY is inputted, search flag is set to '1' and returned to the state of input waiting again, and following inputted characters are handled as the search character string of the search command. When a search command end key SEKEY is inputted, the search flag is cleared to '0'. Next, it is discriminated whether an underline ignore key UNKEY is operated or not and when the underline ignore key UNKEY is depressed, the search is performed while ignoring underlines. In this case, the search can be prepared for designating whether respective changes are ignored or not concerning whether information is printed or not, whether lightness/darkness is inverted or not and whether it is capital letters or small letters in the attributes of all the characters or the change of respective combination.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing device having a calculation function.

[0002]

2. Description of the Related Art Conventionally, an input text is stored in a memory, and when an information processing apparatus for calculating the text executes a command such as a search, an additional character such as underline is added to a character When the information was attached, the command had a one-sided interpretation, and the calculation function lacked flexibility.

For example, when searching for a character string "A", "A" is found, but " A " (A with an underline) is not found. If it is desired to search for a character string "A" regardless of the presence or absence of an underline, it is necessary to search for two character strings "A" and " A ".

In addition, for example, in a command such as calculation, a numerical value without an underline can be calculated, but a numerical value with an underline is regarded as another character and the calculation is not executed. Therefore, in order to execute the calculation of the numerical value with the underline, it was necessary to remove the underline from the numerical value and then execute the calculation command.

As described above, the conventional information processing apparatus has a drawback that it lacks flexibility in the calculation function and is troublesome.

The object of the present invention is to eliminate the above-mentioned drawbacks, for example, to enable desired processing with one command execution even if it is desired to search while ignoring underlines. An object of the present invention is to provide an information processing device capable of calculating numerical values.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings. FIG. 1 shows an embodiment of the information processing apparatus of the present invention.

In the configuration shown in the figure, the CPU is a microprocessor which performs arithmetic operations for information processing, logical judgments, etc., and has an address bus AB, a control bus CB,
The respective components connected to those buses are controlled via the data bus DB.

The address bus AB is a microprocessor C
An address signal for instructing a component to be controlled by the PU is transferred. The control bus CB transfers and applies a control signal to each component to be controlled by the microprocessor CPU. The data bus DB transfers data between the constituent devices.

Next, the ROM is a read-only fixed memory, and stores the control procedure by the microprocessor CPU, which will be described later, as shown in FIG.

Further, the CRT is a display device using a cathode ray tube or the like, and the display pattern of the dot configuration and the display of the cursor on the display device CRT are controlled by the CRT controller. Further, CG is a character generator for generating character signals such as characters, symbols and cursors to be displayed on the display device CRT.

The RAM is a random access memory and is used for temporary storage of various data. SBUF is a search buffer and SFLG is a search flag.

The KB is a keyboard provided with various key groups for inputting various data and giving instructions to the information processing apparatus, for example, arranged as shown in FIG.

In FIG. 2, CIK is a group of various keys such as information processing character keys and function keys, and SSKEY.
Is a search command start key for instructing the start of search command input, SEKEY is a search command end key for instructing the end of the search command, and UNKEY is whether to perform the search regardless of the presence or absence of an underline when executing the search command. It is an underline ignore key that makes a distinction.

To input a search command, enter SSKEY, then the character string you want to search for, and finally SEK
This is done by inputting EY. In that case, UN
If KEY is pressed, the search is performed regardless of the presence / absence of an underline, but if UNKEY is not pressed, only the aforementioned character string will be searched. If the character string has an underline, the underline will be searched. If the character string without "" is not found and the character string is not underlined, the character string with underline is not found.

FIG. 3 shows an example of the internal type of character data.

Bits 1 to 7 are character codes,
For example, the ASCii code is stored. Bit 0 is the underline bit, if bit 0 is 1 then the character is underlined, if bit 0 is 0 then the character is not underlined .

An outline of the operation of the information processing apparatus of the present invention having the above configuration will be described with reference to FIG.

Here, all the operations are executed by the character keys or function keys on the keyboard KB.

First, when power is turned on, step 1 is automatically executed, the search flag SFLG is cleared, and the keyboard is operated.

Next, when a key on the keyboard KB is operated, the process proceeds to step S2 to determine which key has been input, and is roughly divided into three processes depending on the type of each key.

First, the search command start key SSKEY
Is input, the process proceeds to step S3 and the search flag SF
LG is set to 1 and the key input waiting state is restored again. When the search flag SFLG is set to 1, the subsequently input characters are handled as the search character string of the search command.

Further, a search command end key SEKEY
Is input, the process moves to step S4 and the search flag SF
LG is cleared to 0. Next, in step S5, it is determined whether the underline ignore key has been operated.

At this time, if the underline ignore key UN
If KEY is pressed, a search is performed ignoring the underline in step S6.

That is, the search command start key SSKEY
Is input and the search command end key SEKEY is input, the character string input to the search buffer SBuF is treated as a search character string, and a search is performed. Further, in the search ignoring the underline, AND (7F) ₁₆ is performed so as to kill bit 0 of the underline bit for each character data of the character string in the search buffer.
It is carried out by masking by taking, and similarly, by masking and comparing the searched character string in the text. When the search is completed, the system waits for input again. If NO in step S5, step S7
In, a search considering underline is performed.

If the character key GiK is input, it is first determined in step S8 whether the search flag SFLG is cleared to 0 or set to 1. If it is cleared to 0, the step In step S9, the character is not treated as a character forming a search command, normal information processing is performed, and then the key input waiting state is restored.

If the search flag SFLG is set to 1, the character entered in step S10 is treated as one of the character strings forming the search character string and stored in the search buffer SBuF. . Then, it returns to the state of waiting for key input.

In the above-described embodiment of the present invention, whether the searched character string is underlined or not is 2
Although I have only described the changes in types, in addition to these, for each change in the attributes of all characters or their combinations such as whether to print, whether to reverse light and dark, whether it is uppercase or lowercase, May be prepared by designating whether or not to ignore.

Although the command is limited to the search, the present invention is effective regardless of the work as long as the work has different results according to the attribute of the character, such as sorting and calculation.

Although a specific command key is prepared as a command input method, the command key can be substituted by using a combination of keys used for inputting characters etc. without providing such a key. Good.

[0031]

As is apparent from the above description, according to the present invention, when executing various commands such as search and sort, there are various added attributes (for example, attributes such as underline). , It has an excellent effect that can be calculated by ignoring those attributes.
