Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a character processing method and apparatus capable of handling input character information as command information.

[Prior Art] Conventionally, there has been a character processing device that can input characters or the like from a keyboard and use the information (character information) of a series of inputted character strings as command information to instruct a specific task. In such a character processing device, a command instruction and an operation according to the instruction are performed in one step.
There is a one-to-one relationship, and when a specific task is performed many times in succession, the command instruction corresponding to the task must be re-inputted each time, which is a drawback.

[Problems to be Solved by the Invention] As mentioned above, in conventional character processing devices, when a specific task is performed repeatedly using a command instruction, a command instruction corresponding to the task is input each time the task is performed. I had to redo it, and the work efficiency was poor.

[Means for Solving the Problems] The character processing method and device thereof of the present invention have the following means. That is, (1) identifying whether or not the character information inputted from the input means for inputting character information and delimiter information is sandwiched between delimiter information, and based on the identification, regarding the input character information delimited by the delimiter information; is a character processing method that controls the execution of a command corresponding to the character information, which stores the input character information sandwiched between delimiter information, and executes the stored character information each time the re-execution of the character information is instructed. This is a character processing method characterized by re-executing a command based on the character information obtained. Furthermore, (2) input means for inputting character information and delimiter information, and identification for identifying whether or not the character information inputted from the input means is sandwiched between delimiter information of the input means. means, a control means for controlling the execution of a command corresponding to the character information input separated by delimiter information as identified by the identification means; a storage means for storing information; an instruction means for instructing re-execution; and a re-execution control means for controlling re-execution of a command corresponding to character information stored in the storage means based on an instruction from the instruction means. This is a character processing device having the following functions.

[Effect] In other words, when issuing the same command many times in a row, from the second time onwards, you can press a specific key without inputting command information (the above-mentioned "means for executing commands with text information"). By operating , you can perform the same command instructions as before.

[Example] The present invention will be described in detail below with reference to the drawings. FIG. 1 shows an embodiment of a character processing method and apparatus according to the present invention.

In the illustrated configuration, the CPU is a microphone processor that performs calculations and logical judgments for character processing, and is connected to the address bus AB, control bus CB, and data bus DB via the address bus AB, control bus CB, and data bus DB. Control each component.

Address bus AB transfers address signals indicating the components to be controlled by the microprocessor CPU. The control bus CB transfers and applies control signals to each component to be controlled by the microprocessor CPU. The data bus DB transfers data between each component.

Next, ROM is a read-only fixed memory and is used by the microprocessor described later in Figure 3.
Store the control procedures etc. by the CPU.

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

RAM Random access memory used for temporary storage of various data such as command buffer CBuF, stack pointer SPOi, command flag CFLG, etc.

The command buffer CBuF is a memory that stores character information treated as input command information.

The stack pointer SPOi is an index that indicates the storage position when storing a character in the command buffer CBuF, and is added one by one each time a character is stored in the command buffer CBuF. Specifies the storage location.

The command flag CFLG is used to identify whether the input character information is command information or not. For example, in response to the input of "Keisan", if it is mere character information, the characters "Keisan" will be displayed, and if it is "command information", it will be a command to execute a calculation.

KB is a keyboard, and is provided with various key groups arranged as shown in FIG. 2, for example, for inputting various data and giving instructions to this character processing device.

In Figure 2, CIK represents various key groups such as character keys and function keys for character processing, and CSKEY
is the command start key that instructs the start of command input, CEKEY is the command end key that instructs the end of command input and performs processing according to the contents of the command, and CMKEY is the same process as for the previously input command instruction. This is a command execution key for performing.

An outline of the operation of the character processing method and apparatus having the above structure according to the present invention will be explained with reference to FIG.

Here, all operations are performed using the character keys or function keys on the keyboard KB.

First, the command flag is automatically set when the power is turned on.
CFLG and stack pointer SPOi are cleared,
The keyboard is configured to work.

When a key on the keyboard KB is operated, it is determined which key has been input, and the process is roughly divided into four types depending on the type of each key.

First, when delimiter information is input by pressing the command start key CSKEY, the command flag CFLG is set to 1.
, and returns to the state of waiting for key input.
When the command flag CFLG is set to 1, character information input thereafter will be handled as command information.

Next, when the delimiter information is input by pressing the command end key CEKEY, the command flag CFLG is set to 0.
It is cleared by. That is, the command start key
After the starting delimiter information is entered with CSKEY,
When the end delimiter information is input using the command end key CEKEY, the character information sandwiched between the delimiter information is input to the command buffer CBuF, and the character information is treated as command information. Then, the stack pointer SPOi is cleared, and the work corresponding to the command information stored in the command buffer CBuF (in the case of "Keisan", the actual calculation is executed) is executed by the processing unit CPU, and then again. Returns to the state of waiting for key input.

If you want to execute the command in the command buffer CBuF again, if the command key CMKEY is input, the work corresponding to the command information stored in the command buffer CBuF will be executed, and then the state will return to the state waiting for key input again. .

If the character key CIK is input, first determine whether the command flag CFLG is cleared to 0 or set to 1, and if it is cleared to 0, the character information forms command information. Normal character processing is performed (for example, in the case of ``Keisan'', the character ``Keisan'' is displayed) without being treated as a character to be entered, and then the state returns to the state of waiting for key input.

If the command flag CFLG is set to 1, the input character is identified so as to be treated as one of the character information forming the command information. Then, it is stored in the command buffer CBuF at the location indicated by the stack pointer SPOi, and the stack pointer SPOi is incremented by one. After that, it returns to the state of waiting for key input.

As mentioned above, once you enter character information that is treated as command information, that character information is always stored in the command buffer CBuF, and can be stored in the command buffer CBuF by operating the command execution key CMKEY. This means that the task corresponding to the command information is executed.

In the embodiment of the present invention described above, there is only one command execution key CMKEY, and only the work corresponding to the most recently input command is re-executed, but if two or more command execution keys CMKEY are used, By increasing the number of commands to each command execution key CMKEY according to the input order, and operating one of the command execution keys CMKEY, you can execute the command entered last time, the time before last, or before. The corresponding work may be executed.

In the embodiment of the present invention, when the same command instruction is input continuously, the command execution key is used as a substitute for the second and subsequent inputs. You may substitute the command execution key by using a combination of keys used for input. For example, in a kana-kanji conversion type input device, a space key sandwiched between kanji shift keys may be used as a command execution key. For example, it can also be applied when inputting commands to a computer or the like.

[Effects of the Invention] As is clear from the above description, according to the present invention, by identifying whether input character information is sandwiched between delimiter information, if input character information is sandwiched between delimiter information, By controlling the execution of commands corresponding to character information and storing the character information sandwiched between delimiter information, re-execution for the second and subsequent times can be performed with a simple operation.
