DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program control method for an interactive system, for example, an online system for displaying a screen on an online terminal or a program control for an interactive system for displaying a screen on a personal computer.
About the method .

[0002]

2. Description of the Related Art In an interactive system, characters and graphic information are displayed on a display, and an operator inputs information from a keyboard or the like with reference to the display.
Further, by repeating a series of processes for displaying the next screen corresponding to the information input by the operator on the display, the intended business is processed. Conventional techniques for realizing this are roughly divided into the following two.

The first method is used in an interactive system for controlling one display device. The processing method is as follows. When the system is started, data of the screen to be output first is created and displayed on the display, and the display waits until data is input. When data is input from the display device, the input data is processed on the assumption that the data is input from the currently displayed screen.

A second method is used in an interactive system for controlling a plurality of display devices. In this system, data input from the display is provided with a transaction code representing the type of data. Further, for each transaction code, a correspondence of a program for processing data to which the transaction code is assigned is set and stored. When data is input from any of the displays, the control unit activates a program corresponding to the transaction code of the data and delivers the input data. The started program performs processing related to the passed data, creates data to be output to the next screen, and delivers it to the control unit. At this time, processing such as reference update of the database is performed as needed. When receiving the data to be output to the next screen, the control unit outputs the screen to the display to which the above-described data has been input.

[0005]

The above prior art has the following problems. That is, since the program control method is different between the interactive system for controlling a plurality of displays and the interactive system for controlling one display device, a creator of the program must use both methods according to the operating environment of the system. You have to use them properly. Further, the program determines a screen to be displayed next according to a result of processing the screen input data input from the display, and creates screen output data of the screen.
Therefore, when the display order of the screens is changed, it is necessary to change the program.

Further, a program for processing data input from a specific screen is created on the premise of a specific screen to be displayed next to the screen. Therefore, when constructing a business system that uses the same screen a plurality of times, if a screen to be displayed before or after the screen is different, it is necessary to create a program for each combination of screens. On the other hand, the program is created in accordance with a processing method such as a screen input / output method and a transaction processing method provided by a computer system that runs the program. Therefore, in order to test a program, a method that uses a computer with a processing method equivalent to the computer that actually runs the program and a method that uses a computer that is actually operated on a test computer are simulated. Had to be done in one of the ways to work.

As described above, in the conventional method, it is necessary to create a program in a different method for each processing method of a computer, and it is necessary to create a program in consideration of the order relation of screens.

A first object of the present invention is to provide a program control method for an interactive system which does not depend on a processing method of a computer.

A second object of the present invention is to provide a program control method for an interactive system which can create a program independently of the display order of screens.

A third object of the present invention is to provide a program control method for an interactive system that can create a program for a screen and a database.

A fourth object of the present invention is to enable a program developed for one computer to be executed on another computer.
An object of the present invention is to provide a program control method for an interactive system that enables data transfer independent of a processing method of a computer.

Next, in the screen transition diagram of FIG. 5, screens G01, G02, G03, G02
1 will be described with reference to FIG. 7 based on the flowchart of FIG. 2 using the embodiment shown in FIG.

A plurality of display devices are connected to the present system, and each display device displays one of the screens shown in FIG. 5, and at least one of the display devices displays one of the screens. Is the screen G0
It is assumed that 1 is displayed. In the following description, description will be made using a specific one display device on which the screen G01 is displayed and screen data input / output via this display device. That is, in the present embodiment, it is assumed that the “screen output data operation unit for the screen G01” 71 has already been executed.

First, when a user inputs screen data from the display 22 (step 101), the program transition control unit 11 receives the screen input data from the display 22 and stores it in the screen input data storage unit 17 (step 102).

Next, program transition control information and business data are extracted from the program transition control information saving unit 20 and the business data saving unit 21 corresponding to the display 22 (hereinafter simply referred to as a display) to which the screen data is input, and It is stored in the transition control information storage unit 16 and the business data storage unit 19 (step 103).

The program transition control information storage section 16 shown in FIG.
The pointer stored in the currently executing program pointer section 41 is the currently executing program or the program described in the table of the program transition description section 63 which is a part of the program transition storage section 15 in FIG. The position of the program to be executed next is shown.

The program transition control section 11 refers to the program transition description section 63 of the program transition storage section 15 using the pointer of the executing program pointer section 41 of the program transition control information storage section 16 and should execute next. The program name "G01" is obtained. Further, a flag indicating "input mode" is set in the input / output mode setting section 47 of the program transition control information storage section 16, and the program "G01" as the screen data operation section 31 is started (step 10).
4). At this time, a space is set as a control code in the program control code section 43 of the program transition control information storage section 16. As a result, the “screen input data operation unit for screen G01” 72 is executed.

In the program "G01", since the flag indicating "input mode" is set in the input / output mode setting section 47 of the program transition control information storage section 16, the screen input data operation section 12 is executed. The screen input data operation unit 12 checks the data stored in the screen input data storage unit 17 for errors, and if there is an error, sets an error code in the error information transfer unit 42 of the program transition control information storage unit 16 and sets the program. Transition control unit 11
Transfer control to. If there is no error, the information in the screen input data storage section 17 is edited and the business data storage section 19 is edited.
After that, the control is transferred to the program transition control unit 11 (step 105).

In the program transition control section 11, the error information transfer section 42 of the program transition control information storage section 16
(Step 106), if an error occurs, an error message corresponding to the error code of the error information transfer unit 42 is created (Step 107), displayed on the display 22 (Step 108), and the process is terminated. (Step 109). The error message is
This is displayed in the error message display area of the already displayed screen, and is of a format that does not destroy the drawing being displayed.

At this point, a screen "G01" is displayed on the display 22, and an error message is displayed in its error message display area. The user inputs correct screen data with reference to this error message (step 101). Thereafter, the operation up to Step 105 is as described above.

On the other hand, the program transition control unit 11 operates in the error information transfer unit 4 of the program transition control information storage unit 16.
2 (step 106), and if there is no error, first, the pointer of the program pointer section 41 during execution is evacuated (step 110). Next, the program to be executed next is determined by updating the pointer of the program pointer section 41 during execution according to the code of the program control code section 43 (step 111). In this embodiment, a space is set in the program control code. Here, when a space is set as the program control code, the program described in the entry next to the entry indicated by the executing program pointer is specified in the program transition description section 63 of the program transition storage section 15. . Therefore, the running program pointer section 41 of the program transition control information storage section 16 is updated to indicate the entry of the program “D01” described in the program transition description section 63 of the program transition storage section 15. The details of the updating process of the running program pointer unit 41 will be described later.

The program transition control section 11 refers to the program transition description section 63 of the program transition storage section 15 using the pointer of the executing program pointer section 41 of the program transition control information storage section 16 and should execute next. The program name "D01" is obtained. Further, a flag indicating "output mode" is set in the input / output mode setting section 47 of the program transition control information storage section 16, and the program "D01" which is a database operation section is started. At this time, the screen creation flag unit 45 of the program transition control information storage unit 16
Is set with a flag indicating that a screen has not been created. In this embodiment, a space is set. As a result, the “database operation unit D01” 73 is executed.

The program "D01", that is, the database operation unit 14, exchanges data between the business data storage unit 19 and the business database 23. For example,
The data in the business data storage unit 19 is stored in the business database 23
Or read data from the business database 23 using the data in the business data storage unit 19 as a key and set the data in the business data storage unit 19. After a series of these processes is completed, the control is transferred to the program transition control unit 11.
If an error occurs during this processing, the error information transfer unit 4 of the program transition control information storage unit 16
2, an error code is set, and the program transition control unit 11
Is transferred to (step 112).

In the program transition control section 11, the error information transfer section 42 of the program transition control information storage section 16
(Step 113), and if there is an error, after recovering the running program pointer saved in advance (Step 110) (Step 114), an error message corresponding to the error code of the error information transfer unit 42 (Step 107), and the display 22
Is displayed (step 108), and the process is terminated (step 109).

On the other hand, the program transition control section 11 refers to the error information transfer section 42 (step 113). If there is no error, the program transition control section 11 refers to the screen creation flag section 45 of the program transition control information storage section 16 to display the screen. Check whether data has been created (step 11)
5).

When a flag indicating that a screen is not created is set in the screen creation flag section 45 of the program transition control information storage section 16, the pointer of the program pointer section 41 during execution is updated in accordance with the code of the program control code section 43. Thus, the program to be executed next is determined again (step 111), and the subsequent processing is repeated. In the present embodiment, since the screen creation flag section 45 is a space, the process of determining the next program to be executed again (step 1)
Perform 11). At this time, since a space is set as the program control code, the running program pointer is updated to indicate the entry of the program “G02” described in the program transition description unit 53. Therefore, the program transition control unit 11 uses the pointer of the executing program pointer unit 41 of the program transition control information storage unit 16 to store the program transition storage unit 1.
5, the name "G02" of the program to be executed next is obtained. Further, a flag indicating "output mode" is set in the input / output mode setting unit 47 of the program transition control information storage unit 16, and the program "G02" as the screen data operation unit 31 is started. At this time, a flag indicating “screen not created” is set in the screen creation flag section 45 of the program transition control information storage section 16.
Thereby, “the screen output data operation unit of the screen G02” 7
4 is executed.

In the program "G02", since the flag indicating "output mode" is set in the input / output mode setting section 47 of the program transition control information storage section 16, the screen output data operation section 13 is executed. The screen output data operation unit 13 creates screen output data by referring to the data in the business data storage unit 19 as necessary, and stores the screen output data in the screen output data storage unit 18. When creating output screen data,
A flag indicating “screen creation completed” is set in the screen creation flag section 45 of the program transition control information storage section 16. After these processes are completed, the control is transferred to the program transition control unit 11. If an error occurs during this process, an error code is set in the error information transfer unit 42 of the program transition control information storage unit 16, and control is transferred to the program transition control unit 11 (step 112).

Thereafter, the program transition control section 11 checks for an error by referring to the error information transfer section 42 as described above (step 113).
With reference to the screen creation flag section 45 of the program transition control information storage section 16, it is checked whether or not screen data has been created (step 115). When the screen data has been created, the program transition information stored in the program transition information storage unit 16 and the business data stored in the business data storage unit 19 are transferred to the program transition information saving unit 20 and the business data saving unit. 21 (Step 11
6). Next, the screen of the screen output data storage unit 18 is displayed on the display 22 (step 108), and the process is terminated (step 109).

At this time, the executing program pointer section 41 saved in the program transition control information saving section 20
Is the program "G02" described in the program transition description section 63 of the program transition storage section 15.
Shows the entry. Further, a screen G02 is displayed on the display 22. Here, when the user
02 and input screen input data (step 10
1), the program transition control unit 11 receives screen input data from the display 22, and stores the screen input data storage unit 1
7 (step 102), and by repeating the above-described processing, the processing after the “screen input data operation unit for the screen G02” 75 and thereafter is executed.

The updating of the program pointer during execution will be described below in detail.

The pointer of the currently executing program pointer section 41 of the program transition control information storage section 16 is the position where the currently executed screen data operation section or database operation section is stored in the program transition description section 63 of the program transition storage section 15. The execution order of the screen data operation unit 31 (the screen input data operation unit 12, the screen output data operation unit 13) and the database operation unit 14 is controlled by updating this pointer. When the execution order is dynamically changed in accordance with the processing result of the screen data operation unit 31 or the database operation unit 14, the screen data operation unit 31 or the database operation unit 14 uses the program control code unit 43 of the program transition control information storage unit 16. Set the program control code in. The program transition control unit 11 updates the program pointer during execution according to the code set in the program control code unit 43.

FIG. 8 is a correspondence table of functions for realizing program transition and corresponding program control codes.

A method of updating the program pointer during execution corresponding to each function of FIG. 8 will be described with reference to FIGS.

(1) Next Screen In the screen transition diagram, when the screen to be displayed next is uniquely determined, the next screen is designated to be displayed next. For example, when the screen G02 is displayed after the screen G01 in FIG. 5, the screen G01 is specified in the screen input data operation unit 12 of the screen G01. However, in the present embodiment, when the program transition control code section 43 of the program transition control information storage section 16 is not updated in the screen input data operation section 12, it is regarded that the "next screen" is designated. This is realized by setting a space as a program transition control code in the program transition control code unit 43 of the program transition control information storage unit 16 before activating the screen input data operation unit 12. In addition, the program pointer under execution is updated by calculating a value indicating the next entry of the entry in which the currently executed screen data operation unit or database operation unit is stored in the program transition description unit 63 of the program transition storage unit 15. I do.

(2) Branch In the screen transition diagram, when the screen to be displayed next is not uniquely determined, the screen is designated to uniquely determine the screen to be displayed next. For example, it determines whether the screen displayed after the screen G02 in FIG. 5 is the screen G03 or the screen G04. At this time, a branch destination name is specified in the branch destination specifying unit 44 together with the screen control code indicating “branch” in the program transition control information storage unit 16. When the program control code indicating “branch” is designated, the program transition control unit 11 stores the program transition using the “branch destination name” designated in the branch destination designation unit 44 of the program transition control information storage unit 16 as a key. The branch destination name 62 which is a part of the unit 15 is searched, and a line in which the same “branch destination name” is described is specified. Next, the running program pointer of the program transition control information storage unit 16 is updated so as to indicate the second entry from the top of the same line in the program transition description unit 63.

(3) Re-execution The processing relating to the same screen is executed again. The running program pointer of the program transition control information storage unit 16 is updated so as to indicate the screen data operation unit of the currently displayed screen. For example, in FIG. 5, after operating the screen input data of the screen G01, the database operation program D
01, and when "re-execute" is designated here, the screen G01 is updated to indicate the entry.

As shown in the above example, when the screen data operation unit and the database operation unit dynamically change the next program to be executed, the program control code unit 43 of the program transition control information storage unit 16 stores the program control code Set. Program transition control unit 11 in accordance with a program control code of the program <br/> arm control code unit 43, by updating the running program pointer, program
Change transitions dynamically.

Next, the program transition control information storage section 16
The method of using the screen creation flag unit 45 will be described using another embodiment.

FIG. 9 is a screen transition diagram of another embodiment of the present system, FIG. 10 is a layout diagram of one screen in FIG. 9, FIG. 11 is a part of the business data storage unit 19, and FIG. FIG. 4 is an explanatory diagram of an execution order of a screen data operation unit and a database operation unit of each screen.

The embodiment shown in FIG. 9 is an application example of the personal information search system. When the name of an individual to be searched is input on a name designation screen 91, the date of birth of the individual having the same name as the designated name is displayed. A list of addresses is displayed on the same name and same name screen 92, and by specifying a specific individual here, the personal information screen 9 is displayed.
3 is displayed. However, when only one person with the name specified on the name specification screen 91 is registered, the personal information screen 93 is displayed without displaying the same name and same name screen 92.

In this embodiment, first, the screen output data operating section 13 of the name designation screen 91 is executed, and the screen output data of the screen is created and stored in the screen output data storage section 18, and then the program transition control information storage section The 16 screen creation flags 45 are set to a screen creation state (step 1201).

Since the screen creation flag 45 of the program transition control information storage unit 16 is in the screen creation state, the program transition control unit 11 displays the name designation screen,
Data is input from the screen, and the screen input data storage unit 1
7, the screen input data operation unit 12 of the name designation screen 91 is activated. The screen input data operation unit 12 of the name designation screen 91 edits the data of the screen input data storage unit 17 and sets the name in the name area 1001 (step 1).
202).

Since the screen creation flag 45 of the program transition control information storage unit 16 is not in the screen creation state, the program transition control unit 11 does not perform input / output of the screen and searches the next database operation unit, the name database search unit. Start The name database search is performed by the business data storage unit 19
The name database (business database 23) is searched using the name stored in the name area 1001 of the
The name, the date of birth, and the address of all the individuals having the name are set in the same name and the same name area 1002 of the business data storage unit 19 (step 1203).

Since the screen creation flag 45 of the program transition control information storage unit 16 is not in the screen creation state, the program transition control unit 11 does not input / output the screen and outputs the screen output data of the next same name / same name screen 92. The operation unit 13 is started. The screen output data operation unit 13 of the same name and same name screen 92 creates screen output data of the same name and same name screen 92 using the data of the same name and same name area 1002 of the business data storage unit 19.
After storing in the screen output data storage section 18 , the screen creation flag 45 of the program transition control information storage section 16 is set to a screen creation state (step 1204).

Since the screen creation flag of the program transition control information storage unit 16 is in the screen creation state, the program transition control unit 11 displays the same name and name screen 92,
Data is input from the screen, and the screen input data storage unit 1
7, the screen input data operation unit 12 of the same name and same name screen 92 is activated. The screen input data operation unit 12 of the same name and same name screen 92 edits the data of the screen input data storage unit 17 and stores the name and number of the designated individual in the business data storage unit 1.
Nine personal information areas 1003 are set in the area of the name number area (step 1205).

Since the screen creation flag in the program transition control information storage section 16 is not in the screen creation state, the program transition control section 11 does not perform input / output of the screen and the personal information of the next database operation section 14 Invoke a database search. In the personal information database search, the personal information database (business database 23) is used with the name of the personal information area 1003 of the business data storage unit 19 as a key.
Is stored in the personal information area 1003 of the business data storage unit 19 (step 1206).

Since the screen creation flag of the program transition control information storage unit 16 is not in the screen creation state, the program transition control unit 11 does not input / output the screen and outputs the screen output data of the next personal information screen 93. Start the operation unit. The screen output data operation unit 13 of the personal information screen 93 creates screen output data of the personal information screen 93 using the data of the personal information area 1003 of the business data storage unit 19 and stores the data in the screen output data storage unit 18. Thereafter, the screen creation flag in the program transition control information storage unit 16 is set to the screen creation state (step 1207).

Since the screen creation flag of the program transition control information storage unit 16 is in the screen creation state, the program transition control unit 11 displays the personal information screen, inputs data from the screen, and enters the screen input data. After storing in the storage unit 17, the subsequent processing is continued.

On the other hand, a name database search (step 1)
In step 203), if only one individual having the same name is found, the name, the date of birth, and the address of the individual are set in the same name and same name area 1002 (step 120).
3). The subsequent processing in this case is as follows.

Since the screen creation flag of the program transition control information storage unit 16 is not in the screen creation state, the program transition control unit 11 does not perform input / output of the screen and outputs the screen output data of the next screen with the same name and the same name 92. The operation unit 13 is started. The screen output data operation unit 13 of the same name and name screen 92
When the data in the same name and same name area 1002 of the business data storage unit 19 is set for one person, the personal name number is set in the name information area of the personal information area 1003. That is, the same name and the same name screen 92 is displayed, and the same processing as when the individual is designated is performed. Further, the process ends without setting the screen creation flag in the program transition control information storage unit 16 to the screen creation state.

Since the screen creation flag in the program transition control information storage section 16 is not in the screen creation state, the program transition control section 11 does not perform input / output of the screen, and the personal information of the next database operation section 14 Invoke a database search. In the personal information database search, the personal information database is searched using the name of the personal information area 1003 as a key, and personal information such as date of birth, address, occupation, etc. is stored in the personal information area 1003 of the business data storage unit 19 (step). 1206).

As described above, the same processing as when a specific individual having the same name and the same name screen is selected is performed by the screen output data operation unit of the same name and the same name screen 92, and the screen creation flag is set to the screen. By not making the state of creation, in the steps after the personal information database search (step 1206), exactly the same processing can be performed as when displaying the same name and same name screen and when not displaying it.

Next, a method of changing a transaction code will be described with reference to FIG.

In the embodiment of FIG. 6, first, the screen input data input by the transaction code "TR1" is operated by the screen input data operation unit of the screen data operation unit "G01", and subsequently, the database operation unit "D01" is operated. ”And the screen output data operation unit of the screen“ G02 ”, and then the screen“ G02 ”is displayed.

The program transition control unit 11 stores “G0” in the program transition description unit 63 in the program transition storage unit 15.
A search is performed for the screen data operation unit or the database operation unit corresponding to “2”, and the database operation unit “D02” and the screen “G
03 "is executed. The program transition control unit 11 determines the transaction code that has already been saved and the branch destination “R02” of the program transition storage unit 15.
Is compared with the transaction code “TR2” of the transaction code specifying unit 61 corresponding to the new transaction code “TR2”.
"2" is designated to display the screen "G03". As a result, the transaction code changes from “TR1” to “TR1”.
2 ".

As described above, in the present invention, by designating a transaction code in the program transition storage unit 15, the program transition control unit 11 dynamically changes the transaction code.

Next, another embodiment of the present invention will be described. FIG. 13 is a block diagram when the present invention is applied to an interactive system for controlling a single display, and FIG. 14 is a flowchart thereof.

In FIG. 13, only one display 22 exists in the present system, and displays screen data and inputs screen data input from a keyboard or a mouse.
The program transition control unit 11 has a function of storing data input from the display 22 as an input / output device in the screen input data storage unit 17 and a function of outputting data stored in the screen output data storage unit 18 to the display 22. It has a function of activating the screen input data operation unit 12, the screen output data operation unit 13, or the business data operation unit 19 according to the information in the transition storage unit 15 and the program transition control information storage unit 16. That is, the program transition control unit 11
Has almost the same functions as the interactive system for controlling a plurality of displays in FIG. 1, but has a program transition control information storage unit 16 corresponding to the displays in FIG.
And the function of saving and recovering the business data storage unit 19 is not provided. Screen data operation unit 31 and screen input data operation unit 12

By referring to the section 63, the name "G01" of the program to be executed next is obtained. Further, a flag indicating "input mode" is set in the input / output mode setting section 47 of the program transition control information storage section 16, and the program "G01" which is a screen data operation section is activated (step 205). At this time, a space is set as a control code in the program control code section 43 of the program transition control information storage section 16. Thereby, the “screen input data operation unit of the screen G01”
72 is executed.

In the program "G01", since the flag indicating "input mode" is set in the input / output mode setting section 47 of the program transition control information storage section 16, the screen input data operation section 12 is executed. The screen input data operation unit 12 performs an error check on the data stored in the screen input data storage unit 17, and if there is an error, sets an error code in the error information transfer unit 42 of the program transition control information storage unit 16. Then, the control is transferred to the program transition control unit 11. If there is no error, the information in the screen input data storage unit 17 is edited and stored in the business data storage unit 19, and then control is transferred to the program transition control unit 11 (step 206).

In the program transition control section 11, the error information transfer section 42 of the program transition control information storage section 16
(Step 207), and if there is an error, an error message corresponding to the error code of the error information transfer unit 42 is created (step 208) and displayed on the display 22 (step 209). The error message is displayed in the error message display area of the screen that is already displayed, and has a format that does not destroy the screen that is being displayed.

After inputting the screen data from the screen being displayed, the program transition control unit 11 uses the pointer of the executing program pointer unit 41 of the program transition control information storage unit 16 to write the program transition description of the program transition storage unit 15. By referring to the section 63, the name "G01" of the program to be executed next is obtained. Further, a flag indicating "input mode" is set in the input / output mode setting section 47 of the program transition control information storage section 16, and the program "G01" which is a screen data operation section is activated (step 205). After that, the processing after step 206 is repeated.

On the other hand, if there is no error, the program transition control unit 11
It is determined whether or not the processing is to be ended by referring to the end flag section 46 of Step 6 (Step 210).

When the end flag section 46 of the program transition control information storage section 16 is not in the end state, the program transition control section 11 updates the pointer of the running program pointer section 41 in accordance with the code of the program control code section 43. Then, the program to be executed next is determined (step 211). In this embodiment, a space is set in the program control code. Here, if a space is set as the program control code,
Program transition description section 63 of program transition storage section 15
, The program described in the entry next to the entry indicated by the program pointer being executed is specified. Therefore, in the case of FIG. 6, the running program pointer is updated to indicate the entry of the program “D01” described in the program transition description section 63. The method of updating the program pointer during execution is the same as in the above embodiment.

Next, the program transition control section 11 refers to the program transition description section 63 of the program transition storage section 15 using the pointer of the executing program pointer section 41 of the program transition control information storage section 16, and then The name “D01” of the program to be executed is obtained. Further, a flag indicating "output mode" is set in the input / output mode setting unit 47 of the program transition control information storage unit 16, and the program "D01" which is a database operation unit is started. At this time, a flag indicating that a screen has not been created is set in the screen creation flag section 45 of the program transition control information storage section 16. In this embodiment, a space is set. As a result, 73 “database operation unit D01” 7
3 is executed.

The program “D01” transfers data between the business data storage unit 19 and the business database 23. For example, the data in the business data storage unit 19 is written into the business database 23, or the data is read from the business database 23 using the data in the business data storage unit 19 as a key and set in the business data storage unit 19.
After a series of these processes is completed, the control is transferred to the program transition control unit 11. If an error occurs during this processing, an error code is set in the error information transfer unit 42 of the program transition control information storage unit 16, and the control is transferred to the program transition control unit 11 (step 21).
2 ).

The program transition control section 11 refers to the error information transfer section 42 of the program transition control information storage section 16 (step 213). If there is an error, the program pointer stored in advance (step 206) is saved. After the recovery (step 214), an error message corresponding to the error code of the error information transfer unit 42 of the program transition control information storage unit 16 is created (step 208) and displayed on the display 22 (step 2).
09).

After inputting the screen data from the screen being displayed, the program transition control unit 11 uses the pointer of the executing program pointer unit 41 of the program transition control information storage unit 16 to write the program transition description of the program transition storage unit 15. By referring to the section 63, the name "G01" of the program to be executed next is obtained. Further, a flag indicating "input mode" is set in the input / output mode setting section 47 of the program transition control information storage section 16, and the program "G01" which is a screen data operation section is activated (step 205). After this,
The processing after step 206 is repeated.

On the other hand, the program transition control unit 11 stores the error information delivery unit 4 in the program transition control information storage unit 16.
2 (step 213). If there is no error, it is checked whether or not screen data has been created by referring to the screen creation flag unit 45 (step 215).

When the flag indicating that the screen has not been created is set in the screen creation flag section 45 of the program transition control information storage section 16, the program transition control section 11 By updating the pointer of the unit 41, the program to be executed next is determined again (step 211), and the subsequent processing is repeated. In the present embodiment, since the screen creation flag unit 45 of the program transition control information storage unit 16 is a space, a process (step 211) of determining the next program to be executed again is performed. At this time, since a space is set as the program control code 43 of the program transition control information storage unit 16, the pointer of the executing program pointer unit 41 is changed to the program transition storage unit 15.
Is updated to indicate the entry of the program “G02” described in the program transition description section 63 of FIG.

Therefore, the program transition control section 11 refers to the program transition description section 63 of the program transition storage section 15 by using the pointer of the executing program pointer section 41 of the program transition control information storage section 16 and executes the next program. The program name "G02" to be obtained is obtained. Further, a flag indicating "output mode" is set in the input / output mode setting section 47, and the program "G02" which is a screen data operation section is set.
Start At this time, the program transition control information storage unit 1
A flag indicating “screen not created” is set in the screen creation flag unit 45 of No. 6. As a result, the “screen output data operation unit for the screen G02” 73 is executed.

In the program “G02”, since the flag indicating “output mode” is set in the input / output mode setting section 47 of the program transition control information storage section 16, the screen output data operation section 13 is executed. The screen output data operation unit 13 creates screen output data by referring to the data in the business data storage unit 19 as necessary, and stores the screen output data in the screen output data storage unit 18. When creating output screen data,
A flag indicating “screen creation completed” is set in the screen creation flag section 45 of the program transition control information storage section 16. After these processes are completed, the control is transferred to the program transition control unit 11. If an error occurs during this process, an error code is set in the error information transfer unit 42 of the program transition control information storage unit 16, and control is transferred to the program transition control unit 11 (step 212).

Thereafter, the program transition control section 11 checks for an error by referring to the error information transfer section 42 of the program transition control information storage section 16 as described above (step 213). It is checked whether or not the screen data has been created with reference to the creation flag section 45 (step 215).

If the screen data has already been created, the program pointer during execution is saved (step 21).
6) Display the screen of the screen output data storage unit 18 on the display 22 (step 209).

At this time, the saved pointer of the executing program pointer section 41 indicates the entry of the program “G02” described in the program transition description section 63. The display G22 is displayed on the display 22.
Is displayed.

After inputting screen data from the screen being displayed, the program transition control unit 11 uses the pointer of the executing program pointer unit 41 of the program transition control information storage unit 16 to write the program transition description of the program transition storage unit 15. With reference to the section 63, the name of the program to be executed next, "G02", is obtained. Further, a flag indicating "input mode" is set in the input / output mode setting section 47, and the program "G02" which is a screen data operation section is started (step 205). Thereafter, by repeating the processing of step 206 and subsequent steps, the “screen input data operation unit for screen G02” 75
