Description

[Detailed description of the invention] 〔overview〕 Program control [! construction and data structures, etc.

In a logic diagram creation processing device that uses a computer to create/restore logic diagrams represented by graphical patterns, important elements in the control structure such as processing in the logic diagram are extracted according to a specified control level. The logical diagram (a
By providing means for displaying the components as a summary representation on a display.

The overall importance of a large logical diagram can be understood by looking at it.

[Industrial application field]

The present invention relates to a logic diagram summary display processing method in a logic diagram creation processing device, and in particular to a device for creating/editing a logic diagram that describes the control structure and data structure of a program using nine graphic patterns. The present invention relates to a logic diagram summary display processing method in a logic diagram creation processing device that allows the summary to be displayed easily.

In recent years, increasing the productivity of programs executed by computers has become increasingly important. Therefore, it is desired to develop a design document that is easy to structure and a programming language that is similar to human language. In line with this, it is desired to facilitate the creation and preparation of design documents or programs.

[Conventional technology]

In conventional program development, design specifications are described using a flowchart or the like, and coding is performed based on predetermined syntax rules depending on the programming language while referring to the flowchart.

However, conventional flowcharts are not necessarily suitable for structured programs, and it is difficult to intuitively understand the control structure of a program using flowcharts and source programs.

Therefore, we have created a logic diagram in which control structures are represented by graphical symbols, the scope and level of control are clearly indicated by control lines, and five sentences can be written in correspondence with the graphical symbols.
It is considered to be used for program development and maintenance. This logic diagram can be used as a design document, and if the textual parts follow certain rules,
Furthermore, through translation processing, it can be used as a source program, which is considered to be extremely beneficial in improving the productivity, readability, and maintainability of the 5 programs.

However, if creating/editing a logic diagram takes time,
This increases the burden on designers and reduces production efficiency.
It is desirable to be able to create/edit such logical diagrams as easily and quickly as possible.

Conventionally, when creating a document consisting of two graphical elements and a sentence, it was common to create it by hand using a template or the like. Alternatively, such a document has been created using a word processor or the like that can input five graphical elements.

[Problem that the invention seeks to solve]

It has been considered to create the logic diagram by hand or by using a general-purpose word processor, program editor, etc., but this takes a lot of time and effort and places a heavy burden on the designer.

In addition, there is a problem in that it is inconvenient to make corrections, etc.

For this reason, a processing device is being considered which is a device that uses a computer to create/edit a logic diagram while displaying it on a display screen, and which can easily input specific graphical symbols and text portions.

Incidentally, in a logic diagram created by such a processing device, processing is usually detailed in a top-down manner, rather than being described in detail from the beginning. In such a logic diagram, the control level indicating the structure of processing etc. becomes clearer as the details become more detailed, but as the details become more detailed, the logic diagram becomes longer.

It is expected that it will be difficult to grasp the overall outline of the logic diagram.

The present invention aims to solve this problem and to display the entire outline of the logic diagram on a display according to the desired control level, so that the main points of 4a can be easily grasped.

Measures to solve problem C) FIG. 1 is a block diagram of the principle of the present invention.

In FIG.
12 is a summary display instruction input processing unit that inputs a summary display instruction through a menu or the like; 13 is a control level determination unit that determines the control level of each record in the logic diagram; 14 is a logic diagram component extraction unit that extracts components of a logic diagram to be displayed in summary according to the control level; 15 is a summary display output processing unit that displays summary information of the logic diagram on a display;
17 is a summary display editing buffer in which the summary display is edited; 1st is the edited summary display; 19 is a logic diagram which is stored as a code in a memory or the like; 32 is a display; 34 is a printer 551 is a logic diagram. Represents a logical diagram file in which the contents of FIG. 19 are stored.

The logic diagram 19 created by the logic diagram creation processing device 11 is a chart described by a combination of graphical elements representing processes and data structures and sentences representing processes and data contents. 2 for graphical elements that represent the structure
Codes corresponding to various graphical symbols of graphical elements are 1 assigned in the same way as normal character codes 0 The logical diagram 19 to be created/updated is stored in the logical diagram file 51 and read out onto memory as necessary. It will be done.

In this logic diagram 19, control lines indicating the control level ■, O,
Ll, L2. . . . makes it possible to illustrate the hierarchy of five logical structures. This control level becomes deeper by, for example, repeating structure 1 judgment structure, summary block formation, etc. Note that S20 in the logic diagram 19 is a notation for calling an external program, and S21 is a notation for 5 summary descriptions. Generally, it can be considered that the deeper the control level, the more detailed it becomes. With such a logic diagram 19, it is possible to proceed with nine stages of design from general design to detailed design in program development using the same logic diagram.

Instructions regarding editing operations to the logical diagram creation processing device 11 are given by, for example, a menu.

The summary display instruction input processing unit 12 is activated by selecting "Summary Display" from the menu, and manually inputs control level information to be displayed as an e-required display.

The control level determination unit 13 includes a summary display instruction input processing unit 12.
For each record of the logical diagram 19 started by and stored in the logical diagram file 51.

The control level of each record is determined directly or by using an attribute information table (reference omitted) corresponding to each record created in advance.

The logic diagram component extracting unit 14 determines whether or not to select a record of the logic diagram as a summary display according to the control level determination result, and selects a summary display "tM" prepared in advance for the record of the logic diagram for the summary display. For example, if the specified control level is "1", the control level is set to 5 or higher, that is, the control level is "0".
Records with control level "1" are subject to summary display.

Records with a control level of "2" or lower are removed from the summary display. In this case, instead of displaying all the records of control level rOJ and control level "1" as 411'N, within the range of the control level, control groove follow-up important element 1, for example, external program call S20 It is also possible to select a summary description 321 or the like.

The summary display output processing unit 15 has a summary display editing buffer 17.
The process of displaying and outputting the summary display 18 edited above on the 5th display 32 is executed. If the 4Q required display I8 cannot be completely displayed on one screen of the display I32, a scrolling process or the like is performed according to the instruction. It would be even more convenient to be able to print the summary display 18 on the printer 34 if necessary.

[Effect]

When the summary display instruction and control level designation are input by the summary display instruction input processing unit 12, the control level determination unit 13 determines the control level of each record of the logic diagram 19, and extracts the logic diagram components. The unit 14 edits the summary display according to the control level. and,
A summary display 18 is displayed by the summary display output processing section 15.

As a result, a program developer or maintainer of the logic 1'2119 can easily grasp the overall outline of the logic diagram 19.

Especially with the level of detail you want, depending on your level of control.

Since the summary display can be performed, the display level of the summary display can be increased in detail step by step, first displaying the summary at the highest control level, then displaying the summary up to the second control level, and so on. I can go. Therefore,
Even if you want to know the overall processing structure in detail, you can easily understand the structure.
