And having a running status display function 5 that identifiably and displayed in real time as the finished state, at least.

(B) In the program execution status display system described in (a) above, the execution status management function 3 counts the number of executions of each flow chart symbol and registers it together with information indicating the execution state of each flow chart symbol, The execution status display function 5 is characterized in that, at the time of displaying each flow chart symbol, the number of times of execution of each flow chart symbol to be displayed counted by the execution situation management function 3 is added to each flow chart symbol and displayed.

[Action]

In order to make it easy for humans to understand visually, during each test execution of the program, for each of the elements (corresponding to a statement in the high-level language structure) that make up the program, (1) during execution, (2) already executed, (3) Not executed,
(4) The number of times each element is executed is stored, and when the execution of the next element is started, the stored one is updated, and the correspondence on the screen of the interactive terminal is further based on the stored information. By displaying the elements to be displayed in different colors, the execution status of the blocks is displayed in real time on the interactive screen.

〔Example〕

An embodiment of the present invention will be described in detail below with reference to the drawings.

In the present embodiment, the following description will be made assuming that it is applied to an information processing system including a computer and a dialogue terminal. Further, the overall configuration diagram of the information processing system is omitted, and the description will be given based on the characteristic functional configuration of the present invention.

FIG. 1 is a functional configuration diagram incorporated in an information processing system showing an embodiment of the present invention. This information processing system includes an interactive terminal, and the operator develops the program (for example, program test, program debug) while interacting by seeing the messages and programs displayed on the screen of the interactive terminal. , Program reviews, etc.) can be performed.

In FIG. 1, 1 is a program storage function that stores a program and retrieves it as necessary, and 2 is a program execution function that sequentially executes the constituent elements of the program retrieved from the program storage function 1. . Reference numeral 3 stores execution status information for each program element, and is an execution status management function for updating the information about the program element executed by the program execution function 2. A program structure display function 4 displays the structure of the program retrieved from the program storage function 1 on the screen. Reference numeral 5 denotes an execution status display function that displays whether or not each program element on the screen displayed by the program structure display function 4 has been executed according to the execution status information stored in the execution status management function 3. A display device 6 visually displays a program as shown in FIG. 2 described later on the screen in a PAD expression format shown in FIG. 3 described later.

FIG. 2 is a diagram showing an example of a program stored in the program storage function 1 in FIG. This example is known
It is written in the PL / M86 language and consists of program elements shown in line numbers 01 to 28.

Hereinafter, each function of FIG. 1 will be described in detail as an example of the program shown in FIG.

The program storage function 1 retrieves the stored program of FIG. 2 and supplies it to the program execution function 2 and the program structure display function 4. The program structure display function 4 displays the structure of this program on the screen of the display device 6.

FIG. 3 is an example in which the structure of the program of FIG. 2 is displayed on the screen. In Fig. 3, the well-known PAD (Problem Analysis D: Problem Analysis D
iagram) is adopted and displayed. The method of converting and displaying the PAD shown in FIGS. 2 to 3 can be realized by, for example, the method shown in Japanese Patent Application No. 60-228682 previously proposed by the present inventors. Here, 30 indicates the screen of the display device 6, and boxes 35 to 52 are line numbers 01 to 28 in FIG.
It corresponds to each of the program elements of. For example, a box
Reference numeral 35 corresponds to the program element at line number 01, and box 37 corresponds to the program element at line number 03.

On the other hand, the program execution function 2 receives the program from the program storage function 1 and sequentially executes the program elements in line numbers 01 to 28 from the beginning. In the example of FIG. 2, first,
Since the line number 01 exists at the beginning of the program, the program element of the line number 01 is executed, and when the execution is completed, the execution status management function 3 is notified that the execution is completed. By this notification, the execution status management function 3 stores, according to each element of the program of FIG. 2, information on whether or not the element has been executed.

FIG. 4 is a diagram showing an example of the structure of the execution status storage table of the execution status management function 3 in FIG. This is for storing information on whether or not the program element has been executed.

In FIG. 4, the execution status storage table is composed of a field 41 for storing box numbers and an execution status field 42 as shown in FIG. 3, and one storage area is provided for each program element. A structure indicating that the numerical value entered therein is "1" has been executed and the numerical value entered therein is "not executed" is provided. Before the program is executed, "0" indicating that the program has not been executed is stored in all areas. Program execution function 2 is line number
When the program element of 01 is executed and its execution is completed,
The execution status management function 3 is notified of the information that the execution of the program element is completed. Upon receiving this notification, the execution status management function 3 stores "1" indicating that it has been executed in the area corresponding to the program element in line number 01. That is, "1" is stored in the area corresponding to the box 35. Next, the execution status display function 5 manages the execution status information of the program element of each program and the display position of the program element displayed on the screen 30 of the display device 6 in association with the program element. From the function 3, for each received and executed element,
The element on the corresponding screen 30 is displayed as having been executed. FIG. 5 shows a method using diagonal lines as a display mode indicating that the execution has been completed. Further, the display style may be a colorized style or the like. Hereinafter, description will be made using an example of diagonal lines shown in FIG.

Similarly, the program elements on and after line number 02 are sequentially executed, and in response to this, the execution status management function 3 updates the execution status information in the execution status storage table shown in FIG. The execution status display function 5 identifies and displays the executed program elements on the screen 30 based on this, so that the program execution status can be displayed in real time.

FIG. 6 is an operation flowchart of the program execution status display processing by each function of FIG. Hereinafter, description will be given with reference to FIG.

First, the program memory function 1 reads information specifying which program to execute (step 601),
Continue reading the specified program (step 60)
2). Next, the structure of the read program is analyzed by the program structure display function 4 (step 603), and the analyzed program structure is displayed on the screen 30 of the display device 6 (step 604). Before executing the program read by the program execution function 2, the execution status management function 3
Thus, the execution status storage table shown in FIG. 4 is initialized (step 605). Next, the program execution function 2 sets the line number N to 1 and extracts the first program element (steps 606 and 607) and executes the extracted program element (step 608). After execution, the execution status management function 3 stores "1" in the execution status storage table corresponding to the first program element (step 609). After storing, the position size of the box on the screen corresponding to the Nth element is obtained by the execution status display function 5 (step 610), and the box corresponding to the first program element is hatched (step 611). See FIG. 5 for the screen 30 with this hatching. In the program execution function 2, it is checked whether or not there is a next program element (step 612). If there is no next program element, the process is terminated. Return.

In the above embodiment, the execution progress of the program is displayed, but which program element is currently being executed is not displayed. To perform this display, each function of FIG. 1 is expanded as follows.

First, the program execution function 2 is provided with a function of giving not only the information "unexecuted" and "executed" but also the information "executed" to the execution status management function 3. Secondly, the execution status management function 3 includes "unexecuted" for each program element,
In addition to “executed”, a function of storing information indicating “in execution” is added. For this purpose, for example, in the table shown in FIG. 4, "0 (unexecuted)", "1"
In addition to “(executed)”, “2 (in execution)” is stored. When the program execution function 2 provides the execution status management function 3 with information indicating that a certain element is being executed,
The execution status management function 3 writes "2" in the portion corresponding to the element in the table of FIG. Next, when the program execution function 2 provides the execution status management function 3 with information indicating that another element is executing, the execution status management function 3 rewrites the corresponding "2" to "1", and The part corresponding to the element is rewritten as "2".

Thirdly, in the execution status display function 5, for each program element on the screen displayed by the program structure display function 4, depending on the execution status information stored in the execution status management function 3, only unexecuted or executed Instead, a function is added to display so that it can be identified that each is being executed.

In Figure 7, the execution of the program element at line 01 is completed,
Screen when the program element at line number 02 is currently being executed
It is a figure which shows the example of 30. Although there are various display modes for each execution status, this example is an example in which the executed status is displayed by the right diagonal line and the running status is displayed by the left diagonal line. As another example of the display style, a method of distinguishing between executed and executed by monochrome and color may be used.

FIG. 8 is an operation flowchart of the program execution status display processing when the above function is added to the function of FIG.
Hereinafter, description will be given with reference to FIG.

First, information that specifies which program is to be executed is read by the program storage function 1 (step 801), and then the specified program is read (step 80).
2). Next, the structure of the program read by the program structure display function 4 is analyzed (step 803), and the analyzed structure of the program is displayed on the screen 30 of the display device 6 (step 804). Before executing the program read by the program execution function 2, the execution status management function 3
Thus, the execution status storage table shown in FIG. 4 is initialized (step 805). Next, the line number N is set to 1 by the program execution function 2 and the first program element is taken out (steps 806 and 807). It is checked whether or not the line number N fetched by the added program execution function 2 is equal to the line number of the program element currently being executed (step 808). If they are equal, the process proceeds to step 812. If they are not equal, the execution status management function 3 sets "1" to "2" in the execution status storage table corresponding to the program element at line number N-1 (step 809). Next, by the execution status display function 5, N-
The position and size of the box on the screen 30 corresponding to the first element are calculated (step 810), and the calculated box is hatched (step 811). Next, when the execution status management function 3 stores "2" in the execution status storage table corresponding to the Nth element of the matrix (step 812), the execution status display function 5 is notified of this information. Upon receiving this notification, the execution status display function 5 obtains the position and size of the box on the screen 30 corresponding to the Nth element in the line number (step 81).
3) Then, the hatched box indicating the execution is put in the obtained box (step 814). Here, see FIG. 7 for an example of the hatching shown in steps 811 and 813.

Next, the program execution function 2 executes the Nth program element (step 815). After that, it is checked whether there is a next program element (step 816), and if there is an element, the line number N is incremented by 1 (step 81).
7) and returns to step 807. If there is no element, the execution status management function 3 sets the execution status storage table "2" corresponding to the Nth element to "1" (step 818), and notifies the program status display function 5 of this information. Upon receiving this notification, the execution status display function 5 obtains the position and size of the box on the screen 30 (see FIG. 7) corresponding to the Nth element (step 819), and indicates the completed box. Add hatching (step 820).

As the execution status, it may be easier to understand the entire flow if the execution count is displayed on the screen in addition to the execution status, executed status, and non-execution status. Therefore, the following functions are added to the functions shown in FIG. As a first function addition, the execution status management function 3 has a function of storing the number of executions.

FIG. 9 is a diagram showing an example in which the storage structure of FIG. 4 is expanded to store the number of executions. This execution status storage table includes a box number field 91, an execution status field 92, and an execution count field 963.

The execution status management function 3 puts “0” in the area of the execution count field 93 at the start of the program, and executes the execution count field each time the program execution function 2 gives information indicating that an element is being executed. The integer value stored in the storage area of 93 is incremented by one.

As the second addition of the function, in addition to the functions that have been used up to now, the execution status display function 5 receives information about the execution count from the execution status management function 3, and the execution status management function 3 sends the execution count to any position on the screen 30. A function for receiving information about whether to display and displaying the execution count on the screen 30 based on the information is added.

Figure 10 shows a screen displaying the number of executions due to the addition of the above functions.
It is a figure which shows the example of 30. Here, the right diagonal line indicates the box of the executed program element, and the left diagonal line indicates the box of the currently executing program element. The numbers attached to the right shoulders of the boxes 35 and 36 indicate that the program elements of the boxes 35 and 36 have been executed once.

FIG. 11 is an operation flowchart of the program execution status display processing when the function of the third embodiment is added to the function of FIG. Hereinafter, description will be given with reference to FIG.

Since the flowchart of FIG. 11 has a process for displaying the number of executions added between steps 814 and 815 of the flowchart of FIG. 8, only the processing operation of that part will be described here. That is, after the process of step 814, the execution status display function 5 adds this information by adding "1" to the execution count of the storage table (see FIG. 9) corresponding to the N-th element by the added execution status management function 3. (Step 1101). When this notification is received, the execution position display function 5 is added to obtain the execution position display position (step 1102), and the execution number is displayed on the screen 30 (No.
(See FIG. 10) (step 1103). After that, the processes of step 815 and thereafter as described above are performed.

Although the above description is directed to an example in which the program structure is displayed in the PAD expression format, it is also possible to adopt a flowchart as the display format of the program structure. Differences between the flow chart adoption and the PAD adoption as the display format of the program structure are as follows.

The program structure display function 4 is to display the structure of the program given from the program storage function 1 on the screen as a flowchart.

Based on this difference, the present invention can be implemented by performing the following function expansion with respect to FIG.

FIG. 12 is a diagram showing a rule table corresponding to program elements, PADs, and flowcharts. Program display function 4
According to the correspondence in Fig. 12, a function to convert from PAD to flowchart is added. For example, conversion of a concatenated sentence from PAD to a flowchart is performed according to rule 73. Similarly, in the case of repetition, rule 74, in the case of judgment rule 75, DO CASE
In the case of sentences, it is according to Rule 76.

FIG. 13 is a processing operation flowchart of the function for converting the PAD into the flowchart, which is added to the program structure display function 4 in FIG.

It is checked whether or not the box subjected to the structural analysis is a box of a connected sentence (step 1301), and it is converted into the form of rule 73 (step 1302). It is checked whether there is a next box (step 1303). If there is a box, the process returns to step 1301. If there is no box, the process ends. Step 1301 If there is no box that means concatenation, check whether there is a box that means repetition (Step 130).
Four). If there is a box, convert it to Rule 74 (Step 1
305). If there is no box, it is checked whether or not there is a box indicating the judgment (step 1306). If there is a box, it is converted to the form of rule 75 (step 1307), and if it is not, it is converted to the form of rule 76 (step 1308). ).

The above method can be applied to the case of displaying in a format other than the flowchart. In this case, a conversion rule table corresponding to the display style is provided. By creating a dictionary of these conversion rules, the functional configuration for facilitating the conversion of the display format is as shown in FIG. This is provided with a conversion dictionary for converting the structure of the program from PAD to another graphic structure in the configuration of FIG.

FIG. 15 is a flowchart of the processing operation of the dictionary function 7 in FIG. Hereinafter, description will be given with reference to FIG.

First, when the display style information is input by the operator, the display style designation information is read (step 1501), and the conversion rule of the designated display style is retrieved from the stored memory (step 1501).
1502), the conversion rule table of the designated display format is passed to the program structure display function 4 (step 1502).

Through the above processing, the PAD program structure can be converted into another program structure.

As described above, in the present embodiment and other embodiments, when the program is tested, the structure of the program is displayed on the screen of the display device (interaction terminal) 6, and (1) executed, (2) During execution, (3) Determine whether it is not executed,
By displaying the screen corresponding to each execution, the test execution status can be displayed visually.

〔The invention's effect〕

As described above, according to the present invention, when the program is tested in the development of the program or the like, the progress of execution of the program is visually displayed in real time on the display device, so that the entire program It becomes easy to understand the flow of. Further, since the position currently being executed and the number of times of execution are displayed, it becomes possible to easily visually understand the abnormality of the path. Therefore, the efficiency of program testing and the like can be improved, and the number of man-hours for program development can be reduced.
