Abstract

PURPOSE:To easily execute a correction, etc. in case of processing a mathematical expression, by bringing a hierarchical correspondence of parentheses to count-up and count-down, in case of the left parentheses and the right parentheses, respectively, and bringing depth of the hierarchy to a suffix display. CONSTITUTION:When a working object of one text sentence exists in a text sentence buffer 1 and a display instruction is executed by an operation from an input operating part, a parentheses managing means fetches the text sentence by one character each to a display scanning side and decides the right parentheses or the left parentheses, and in case of the left parentheses, count-up is executed, and in case of the right parentheses, count-down is executed, and in case said character is not the left nor right parentheses, it is displayed as a character as it is. In case of the left or right parentheses, a processing for justifying that which has selected parentheses provided with a suffix, related to a value of a parentheses register 2', or has added a suffix portion, to a display buffer 3 is repeated by a portion of one text sentence, and when the processing is ended, it is displayed on a display part 4.

Description

[Detailed Description of the Invention] 3. Detailed Description and Summary of the Invention> When editing text using the LISP language, etc., the number of parentheses in the sentence is too large (the person operating it)
It becomes confusing to keep track of the number of layers, leading to errors, and reduces productivity and operability due to checking time and attention.

The purpose of this case is to provide a terminal device with a means to automatically manage the hierarchy of parentheses displayed on the screen according to the number of input parentheses as an usability support tool, and a means to display the parentheses hierarchy as a suffix so that it can be operated easily by humans. <Industrial Application Field> The present invention relates to a data processing system, and in particular, it reduces the input load and judgment load on the operator when creating or editing a program using, for example, LISP' as the language used. The present invention relates to a terminal device equipped with a support function prepared for the purpose of improving operability and productivity by reducing the number of operations.

<Prior art and problems> When creating a program or editing a program, the operator must use the display screen as a monitor to input and make corrections.

Cutting out, erasing, changing the order, etc. are performed, and devices for performing these operations are also known. However, when performing editing work such as importing and editing for such input and correction, it is normal for the processing device to have a means to verify consistency at the stage of the created text. It is usually possible to detect an error in a program that has gone wrong before it is compiled, but even if it is detected at this stage, it is too late to correct the error, and it is too troublesome to find the correct place and fix it. However, there was a problem in that a significant part of the previous work was wasted.

In addition, in order to prevent such errors from occurring in advance, it is possible for the operator to be careful and manage them in his or her mind during operation. I'm sure there's a problem.

For example, when a large number of parentheses are used in the expression, such as text editing in a program that processes mathematical formulas or text editing in LISP, and the correspondence between the parentheses has an important meaning, it is not possible to visually manage the parentheses on the display screen. Management of hierarchical correspondence is difficult, and especially when a long text sentence does not fit on one line, there is a problem in that careful concentration of attention and operation overlap, deteriorating operability and reducing productivity.

In view of the above, an object of the present invention is to automatically manage the hierarchical correspondence of parentheses (commonly referred to as nest correspondence) in such cases based on the presence of parentheses, and to display the hierarchy R-X as a suffix. To provide an editing means that can lighten the burden on an operator, facilitate the discovery of errors at that point, and improve productivity.

Means for solving the problem〉 It is possible to achieve all of the above objectives by using a display means (such as a display part of a display device) and an operation input means (
the same keyboard, etc.] and their control processing means (input/output control of the keyboard display unit, data reading from the memory file, data storage in the memory file, and control for transferring data to the host 110 in the case of a subsystem) Processing unit) t-Means for detecting the beginning and end of one text sentence in a terminal device that may be equipped with: (can be done by hardware, firmware, or instructed by the operator) and display as one text sentence Means to scan the attributes of the presence of parentheses present in the text displayed on the display screen in digit order, and count up if the parenthesis is a left parenthesis, and count down if it is a right parenthesis: (Initial) and zero for the reset value, it can be a hardware counter or firmware), and each time the above count value changes, the left parenthesis that displays the VC at the corresponding screen position should be selected with a suffix that matches the value after counting, and the stone The parentheses are a means to select the one with a suffix that matches the value immediately before the countdown: (The contents include a verification means as a logical means, a means for storing suffixes or parentheses with suffixes, and a selection means as a logical means, and it can be done by hardware or firmware. However, it can be realized by providing the following.

Equipped with such a configuration function, whether the operator creates it manually from the input operation means or reads it from a file and edits it, the hierarchy of parentheses in a text sentence can be seen in the suffix. Even if a partial display is blurred, it can be seen immediately and at a glance, and strange situations can be easily detected by simply displaying a partial display.It is a powerful tool that not only reduces the burden on the operator but also supports improved operability and productivity. Embodiment that can provide a terminal device equipped with a tool> FIG. 1 is an explanatory diagram of an embodiment that embodies the principle diagram of the present invention, and shows a processing flow diagram of hierarchical management and display as a system assist tool. Figure 2 is a supplementary figure to Figure 1, showing the representation of the original text sentence extracted into text sentence buffer 1 and the parentheses I'
! 2. Among the means constituting the logic means 2, FIG. 3 is a comparison of the count value of the number of parentheses counting means (bracket register 2') and the expression of the text sentence in the display buffer 3, according to the present invention. Figure 4 shows an example of a text sentence displayed on the display in the conventional format for comparison. Source buffer 6 is also input during the configuration shown in Figure 1. The operation unit 5, the display buffer 3, the display unit 4, and these control processing units (not shown) are necessary to establish the embodiment, but they correspond to the conventional example, and one text sentence buffer is required. 1 also exemplifies a container to be processed, and the new part in the embodiment corresponds to a parenthesis register 2' as a container for processing and data included in the parenthesis management means 2 enclosed by dotted lines.

Further, characters other than parentheses are transferred to the display buffer 3 in the same manner as in the conventional case.

The initial value or reset value of the Matakatsuko register 2' is set to zero.

The operation of the parenthesis management means 2 as an additional tool will be explained based on the above premise. If a text sentence to be processed exists in the text sentence buffer 1 and a display instruction is given by an operation from the input operation section 5, the parenthesis management means 2 will be explained. Extracts the text sentence one character at a time to the display scanning side, checks the right parenthesis and left parenthesis, and if it is a left parenthesis [open parenthesis [class]], counts up the value in the parenthesis register 2', and determines the right parenthesis [
(closing parenthesis)], the value in the parenthesis register 2' is counted down, and if it is neither a left parenthesis nor a right parenthesis, it is stored as a character in the display buffer 3. If ``na'' is a left or right parenthesis, the process of filling the display buffer 3 with the force with the suffix associated with the value of the parenthesis register 2', or by adding the suffix. When the above processing for one text sentence is completed, it will be displayed on the display section 4. If you want to supplement the 0 in the middle, the numerical value of the above suffix is a left parenthesis, after the operation when the parenthesis register 2' counts up. If it is a right parenthesis, it is automatically set to a value that matches the value before the operation (even if the value after the operation is automatically +1 added) of the value counted down by the parenthesis register 2'. It is characterized by having a built-in tool that supports the operator's work with the function of executing such processing in conjunction with the instruction operation on the display. 1. Since the addition of a suffix is allowed in the expression format of a text sentence after correction, it is possible to compile it as it is, and the fact that it is converted for convenience of display by such a tool is itself the content of the program. We believe that there is no need to carry out a full concrete demonstration to prove that the conversion means described above can be implemented as a relatively simple logical process, for example, in hardware or as a firmware.

The same result can be obtained by storing "parentheses with suffix" in memory for each parenthesis hierarchy and assigning them instead of adding a suffix to the parentheses as in this embodiment.

Effect> As explained above, according to the present invention, it is possible to make the hierarchy of parentheses visible to the operator at a glance during editing work by adding only a small amount of additional means and logical procedures. 0 that has a distinctive effect
